    8 x16 vents that are passive Should I close up the vents and install mechanical exhaust only ventilation and if so how much do i need What codes or formulas do i need to use to size the exhaust only ventilation Or what is your recommendation on treating this crawlspace area The exterior walls of this crawlspace are insulated with 1 5 bead board on teh walls and above grade it is 3 of bead board insulation Looking for advice Answer In a primarily heating environment like MN extending the ground cover vapor barrier up the crawl walls and sealing it to the rim joist underside of the floor as you plan is the correct choice Permanently sealing the foundation vents is also the correct call The intent is to bring the crawl space inside the building envelope There is huge amount of information on this topic available free at buildingscience com should you wish further confirmation or detail Crawl space exhaust venting while it probably isn t necessary unless you are concerned with radon or some other untreatable ground source pollutant or if you want backup redundancy in case the ground cover air vapor seal fails will do no harm beyond slightly increasing the building heat load to condition the exhausted air and adding maintenance fan electrical use costs As for sizing the fan and determining its CFM setting I would suggest that the smallest fan running 100 of the time and set at the lowest CFM that would create a very slight depressurization say one PA or less in the crawl when the space is completely closed up should be sufficient Tony Gill From Aaron Cate Subject Rules and Guidance Question I have question concerning ASHRAE 62 2 2010 Option 1 says specify that each bathroom recieves 50 cfm intermittent or 20 cfm continuous and kitchen to recieve 100 cfm of intermittent exhaust If i can achieve the continuous ventilation needed by just doing the bathroom fan does this mean I still have to install the kitchen exhaust I need some clarification on this Answer The ASHRAE 62 2 2010 Standard requires 1 local ventilation in bathrooms AND kitchens and 2 whole building ventilation However if you choose to use the alternative compliance approach Appendix A of the Standard for existing homes you may reduce or even eliminate the requirement for local ventilation but you must increase the whole building ventilation rate to compensate for the deficiency in local ventilation Let s look at two examples the first meeting the minimum requirements of the Standards without using the alternative compliance approach First you must verify that an existing fan or a new fan you install is providing 50 CFM on demand or 20 CFM continuous in the bathroom if there are multiple bathrooms you must provide this in each Second you must verify that an existing fan or a new fan you install is providing 100 CFM on demand in the kitchen Finally you must size the whole building fan and install it The whole building fan size is dependent on the square footage of the dwelling and the number of bedrooms let s assume this is required to be 30 CFM for continuous operation For the second example we will use the alternative compliance approach Let us assume that the house has an existing 20 CFM fan in the bathroom and that it has no fan in the kitchen You decide that it will be too expensive to upgrade the bathroom fan and install a kitchen fan Using the alternative compliance approach there is a 30 CFM deficit in the bathroom 50 CFM required but only have 20 CFM and a 100 CFM deficit in the kitchen 100 CFM required but have zero CFM Each of these deficits can be reduced by 20 CFM if there is an openable window in the bathroom and kitchen let s assume there is So we have a final deficit of 10 CFM in the bathroom and 80 CFM in the kitchen The Standard requires us to sum the deficits 90 CFM and divide them by 4 for a result of 23 CFM This 23 CFM must be added to the required whole building ventilation rate to compensate for the deficits in the local ventilation So based on the first example we would add 23 CFM to the required 30 CMF for whole building ventilation a result of 53 CFM Each of these examples complies with the minimum requirements of the Standard but the first does not use the alternative compliance approach It is likely that the first example will provide better indoor air quality but the second would be significantly less expensive to install For more detailed information take a look at the ASHRAE 62 2 2010 Standard especially Appendix A Rick Karg From Amy Hollander Category Health and Safety Subject PPE necessary for exterior wall insulation Question Does the RRP personal protective equipment rule and training require full protection when blowing outdoor sidewalls I have a film on sidewall insulation but it is quite dusty and the guy is wearing a dust mask instead of a respirator Is this the rule if you are going to disturb more than 20 sq ft of outdoor siding you have to wear a respirator Answer According to EPA RRP Rules if you are disturbing an exterior surface greater than 20 feet on a pre 1978 house that has been tested positive for lead or presumed to have lead the minimum recommended respirator protection is a disposal P 100 respirator A dust mask would not provide adequate protection Mike Vogel Subject ASHRAE 62 2 Question I would like to install a small hrv in a modular home actually thiry modular homes I don t have a lot of space need a small unit 20 to 40 cfm currently looking at the Zehnder Please advise on products Answer The first place to look for HRV ERV performance is the HVI Certified Product Directory which has the performance information on all of the certified products I find the directory tough to search because there s a lot of information there but it is the best reference The second point is to look at the Gross Airflow and Net Supply Airflow ratings The Gross Airflow ratings include the cross flow leakage and should be used for duct design The Net Supply airflow subtracts the measured cross leakage and is the actual amount of outdoor air delivered by the supply system of the unit and should be used for meeting the required ventilation rate And make sure you are comparing the same efficiency numbers The directory defines these things well Apparent Sensible Effectiveness ASEF The measured temperature rise of the supply airstream divided by the difference between the outdoor temperature point 1 and entering exhaust system air temperature point 3 then multiplied by the ratio of mass flow rate of the supply airflow divided by the mass flow rate of the lower of the supply or exhaust system airflows Apparent Sensible Effectiveness is useful to predict final delivered air temperature at a given flow rate and should be used for energy modeling when wattage for air movement is separately accounted for in the energy model Sensible Recovery Efficiency SRE The net sensible energy recovered by the supply airstream as adjusted by electric consumption case heat loss or heat gain air leakage airflow mass imbalance between the two airstreams and the energy used for defrost when running the Very Low Temperature Test as a percent of the potential sensible energy that could be recovered plus the exhaust fan energy This value is used to predict and compare Heating Season Performance of the HRV ERV unit Total Recovery Efficiency TRE The net total energy sensible plus latent also called enthalpy recovered by the supply airstream adjusted by electric consumption case heat loss or heat gain air leakage and airflow mass imbalance between the two airstreams as a percent of the potential total energy that could be recovered plus the exhaust fan energy This value is used to predict and compare Cooling Season Performance for the HRV ERV unit This table includes a handful of the smaller systems Some of them have ECM motors that can be speed controlled but these are their HVI performance

Paul H Raymer From Al Gleason Category Health Safety Subject CAZ depressurization Question WAP Notice 11 6 references combustion appliance zone depressurization testing for Solid Fuel Heating when conducting a required chimney and flue inspection pre weatherization What is the CAZ depressurization Pascal limit for atmospheric wood stoves Answer Because there is wide variation in the design of solid fuel appliances this is a challenging question For example an air tight wood stove is likely to be more resistant to surrounding negative pressure than a non air tight stove Additionally there is much variation of draft strength within the normal operating range of a given appliance For example the draft of a wood stove is stronger 30 minutes after loading it at night than it is eight hours later just before its morning loading I think a reliable resource for wood stove depressurization limits is the Minnesota Energy Code 7672 0900 2005 edition This Code states that the maximum depressurization for closed controlled combustion wood burning appliances is 7 pascals 0 028 inch water column The same table lists decorative wood burning appliances as 5 pascals 0 02 inch water column Unfortunately these two types of wood appliance are not defined by the Code The Minnesota Code makes it clear that if a manufactured certified negative tolerance rating is available it should be used instead of the above limits This information indicates that these wood burning appliances are more resistant to depressurization than Category I natural draft gas fired water heaters 2 pascals and have about the same resistance as natural draft oil and gas fired furnaces and boilers 5 pascals Because of the inherent variability of wood stove design and operation I suggest using care when doing combustion safety testing for these appliances Additionally a working carbon monoxide alarm installed in the room in which the stove is located is very important Solid fuel appliances ALWAYS produce carbon monoxide if a stove is spilling carbon monoxide is entering the house air Rick Karg From Amanda Clyne Category Health Safety Subject Mobile homes and condening furnaces Question What is the proper way of disposing the condensate from the furnace if there is no drywell or ground drainage system available for a mobile home Also how do you stop the condensate line from freezing under the mobile home belly Note skirting is present Answer 1 I would run it into a washer or other drain in the home you could probably run the line in the belly over to the other drain that way it would be out of the way and still not freeze or make a French drain under the home trench and pea gravel run a steep drain and larger diameter pipe with some insulation Joe Hall Answer 2 Click here for Answer 2 Stacey Keys From Dave Masse Category Health and Safety Subject ASHRAE 62 2 Question I am currently looking into whole house ventilation to meet ASHRAE 62 2 2010 Are there any Ceiling Mount HRVs I see Panasonic makes a Ceiling Mount ERV the FV 04VE1 I am looking for a similar unit that is a HRV The big attic closet under floor mount HRVs are too complex and time consuming to install and then periodically service the filter A nice ceiling mount HRV to provide balanced ventilation would be great but I can t find any Also do you know of any wall mount ventilation fans that are one sone or less I see the Panasonic FV 08QW1 at 1 1 sone Close but not good enough As far as I can tell the only good choices for meeting 62 2 are ceiling mount exhaust fans or attic mount inline exhaust supply fans Your response to my questions will be greatly appreciated Thank you in advance for your time and expert advise Answer 1 I know of no ceiling mount HRVs and I know of no 1 sone or less wall mount I have viewed the 1 1 sone wall mount as meeting the to the extent possible part of the WAP requirement Paul W Francisco Answer 2 I don t know of any single point HRV that are readily available Although it is difficult to get a handle on all of the different models that all the different manufacturers are making I do think that Mr Masse needs to recognize that any HRV or ERV needs regular service and filter cleaning You might consider running a duct down from the bathroom to an in line fan or an externally mounted in line fan like the Fantech RVF4 or RVF6 Because it is a remote mounted fan it is exempt from the sound requirement as long as he has 6 feet of ducting Although I think the RVF6 is fairly noisy But going down and out is often one of the best options Paul Raymer From Mark Crabtree Category Health and Safety Subject ACH Combustion Air Question I have a unique issue I have a home with 1 102 sq ft 8 816cu ft with two exhaust fans that measure out at over 150cfm each These are not continuous flow fans I do not have ACH in the home but at the same time I do not have enough combustion air for two appliances at 102 000 btu s These are located in a small open room with a clothes dryer which is creating a roll out problem on the water heater WHAT DO I DO Answer The problem you describe is not unusual and it can be hazardous Flame rollout from a combustion appliance can create carbon monoxide in the living area and can damage the controls on the appliance leading to malfunction As you have found the dwelling has too much negative pressure when the fans and the dryer are operating There are a number of options for solving this problem I will begin with the least expensive and move on from there First you can add enough make up air to comply with the mechanical code used in your area and to relieve the excessive negative pressure in the space You can use a passive make up air system the least expense or a mechanical make up air system that supplies air to the house when the water heater is operating Second you can downsize or eliminate one or both of the 150 CFM exhaust fans You don t indicate what the uses of these fans are so I can t comment on that but if their function allows downsize or eliminate one or both Finally you can change out the water heater to another type that is more resistant to backdrafting and rollout I suggest a Category III forced draft unit that vents through the wall This water heater type with a positive pressure in the vent connector has the ability to withstand three to four times the negative pressure in the dwelling as a standard Category I natural draft unit You have done your client a great service by discovering this hazardous problem Rick Karg From Randall Olsen Category Monitoring Subject Mobile Home Rodent Barriers Question Is a rodent barrier underbelly required on a mobile home If the rodent barrier is very damaged can it be removed the floor insulated with batts twined and no rodent barrier installed Answer We used to do something similar to this in the old days first off it s very labor intensive and shall we say not so pleasant of a job It also leaks quite a bit of air and leaves lots of holes for varmints to enter the belly cavity It would be easier and more efficient if the belly was a flat or longitudinal floor system but if it s a hanging belly or crosswise floor system then I would say there is a better way We use tyvek or other house wrap material and staple and or nail it to the wings then we use about a 9 foot wide piece cut as long as the trailer and thread it through the supports under the duct system in the middle of the trailer We then spread it out and secure it to the floor joists next to the I beam We then blow the belly in the normal way from the side It sounds harder than it is It s actually much easier than insulating the belly using batts Cal Steiner From Mark Kapner Category Technical Tools Subject Gas Furnace Tune Up Question What is the expected improvement in steady state furnace efficiency for a residential gas furnace tune up following your guideline What is the baseline furnace efficiency and the efficiency after the tune up Answer 1 A furnace tune up often referred to as a clean and tune is typically done in WAP as part of the overall furnace inspection Quite often the systems have not received regular maintenance and have soot build up The furnace is cleaned combustion analysis testing is done for CO levels stack temperature O2 levels etc and then tuned to the maximum efficiency that can be reached The expected improvement is that the SSE will be at or close to the original SSE for the unit for instance an 80 SSE unit will test at 80 or close to it and a newer 90 high efficiency unit will test at the manufacturer s suggested level after the tune up It is more difficult to answer when the unit is very old and the rated SSE is unknown I think many HVAC technicians base the desired and realistically expected SSE on their experience with similar units maybe with an expected SSE of 72 or 76 on older units and maybe even lower on very old units The units with lower SSE s may be candidates for replacement based on potential energy efficiency savings Bob Scott From Bill Beachy Category Health and Safety Subject ASHRAE 62 2 and Multifamily Question Should ventilation fans in a multi family building be set the same for all units on all floors especially if the CFM readings differ from the lower and upper floors Answer 1 First I am going to assume that this question has to do with whole building ventilation rather than local ventilation intended to exhaust moisture from bathing activities from bathrooms and cooking related pollution from kitchens For multifamily buildings the ASHRAE 62 2 committee has defined the word building in the term whole building to mean single dwelling unit For whole building ventilation ASHRAE 62 2 2010 does not specify that ventilation rates should be set at the same flow rate for each unit in a multifamily building nor does it specify a method of determining this ventilation rate other than the procedure used for a single family buildings Because the ASHRAE standard is silent on this issue I will express my opinion It is important to understand that my opinion does not necessarily express the sentiment of the ASHRAE 62 2 committee nor the DOE low income weatherization program s policy regarding ASHRAE 62 2 2010 OK here goes Because it is difficult in multifamily buildings to be certain whether infiltration as measured by the blower door is from outdoors or from other apartment units size the ventilation flow rates assuming no infiltration credit based on the square footage and number of bedrooms Note that the ASHRAE 62 2 committee has passed an addendum that will be part of the 2013 edition that specifies exactly this so this position can be considered the view of the committee members even if this addendum is not a part of the version of the standard required by DOE Rick Karg with the wise and kind help of Paul Francisco ASHRAE 62 2 committee members Answer 2 About the only thing I could add is that if they made an honest attempt and could not find an appropriate sone fan install the next best fan I would then get a waiver from the state and document all the searches and info that went into the decision to go with a lesser fan I have not had the time to research this properly however so I m relying on their info that a low sone fan cannot be found for mobiles I would if I were the state receiving the request for the waiver ask if they contacted several fan companies for advice Cal Steiner From Dan Auer Category Technical Tools Subject Bath Fan Controls Question I am looking for a fan control that will have the fan run a few minutes every hour I have installed the airetrack and am now hearing of a smart switch Do you know this product or alternates please advise Answer I m not aware of a specific smart switch but there are several out there that are programmable both for fan speed and cycled run time Most have an override to boost to full speed when desired The EFI website catalogue is a good source for what s generally available Try http www energyfederation org consumer default php cPath 39 766 Tony Gill From Henry DeWerth Category Technical Tools Subject Balanced Return Air Pathway Question If an agency bid proposal included a line item that simply stated install jump duct in all bedrooms in this scenario the supply ducts are in conditioned space and the Building Code terminology is transfer ducts would it not be considered prudent to install RAp devices in the partition walls to keep the return air in conditioned space versus running flex duct runs in an unconditioned attic to a common ceiling grill We are in a hot humid Florida climate and the attic temps can be 140 at times We think that keeping the return air ducts in conditioned space would yield higher efficient installation and reduce the loads on the heat pump Would this be true Would this method be preferred by DOE on a heat pump change out It would also cost less to implement Answer A jump jumper or transfer duct serves the function of 1 allowing a free return air pathway so that the space conditioning system can do a more effective job of conditioning and 2 minimizing pressure imbalances in rooms with closed doors during air handler operation In some cases doors can be undercut rather than installing transfer ducts Clearly in the case here transfer jump ducts are being specified rather than undercutting doors this is preferred to undercutting It is always best if ducts can be kept within the thermal pressure envelope of the dwelling This minimizes heat transfer to and from conditioned air in the ducts and is likely to make any duct leakage less of an energy drain So it would be more efficient in Florida to install transfer ducts in interior walls rather than through the hot attic This will reduce the heat pump loads summer AND winter and save energy Another advantage to keeping ductwork out of the attic is the elimination of the possibility of condensation on the outside of the ducts during cooling season Because transfer ducts are often installed to serve bedrooms it is important be aware of the movement of sound If a transfer duct consists of two grilles across from one another in a partition wall sound will move freely through this direct hole A better method is to vertically offset the grilles on either side of the partition wall stud bay by three feet or more Although I don t speak directly for DOE I think it is safe to assume DOE would agree with Henry s ideas for transfer ducts Rick Karg From Dean Cibotti Category Training Subject Strapping a cathedral ceiling Question I am wondering if strapping affects the insulative values of insulation The drywall contractors want to strap but I am not sure have a 1 2 barrier before the kraft face is a good idea Answer Drywall contractors and many builders prefer to strap ceilings before installing drywall because strapping evens out any irregularities in the joists For example if one joist bottom is a half inch higher than the two adjacent ones the strapping will eliminate the problem especially if wood shims are used ensure straight strapping and an even drywall plane However this practice does add a ¾ inch to ½ inch air space between the bottom of the insulation facing and the top of the drywall As it turns out this space can be beneficial to the R value if the space has no air flowing through it The additional R value created by the air space is approximately 0 75 with the kraft paper facing On the other hand if the fiberglass were foil faced the added R value from the air space would be approximately 2 0 The additional R value from the foil facing can be attributed to the radiant component of heat transfer That is the foil reflects infrared energy much more readily than the non reflective kraft paper So not only is the strapping a good technique for ensuring a more even ceiling plane but it can enhance the ceiling R value A warning is appropriate for this strapping detail It is important to ensure that the air space created by the ceiling strapping is sealed so that air cannot flow through it and thereby eliminate or more than offset any R value gained Rick Karg From Andy Caler Category Technical Tools Subject ASHRAE 62 2 2010 Question This question was brought to my attention by one of our agencies here in Colorado The issue is with how in the Ventilation section of 11 6 it states Implementing ASHRAE 62 2 is not required where acceptable indoor air quality already exists as defined by ASHRAE 62 2 ASHRAE defines acceptable indoor air quality as air toward which a substantial majority of occupants express dissatisfaction with respect to odor and sensory irritation and in which there are not likely to be contaminants at concentrations that are known to pose a health risk Is this as straightforward as it sounds Are auditors required to determine if a house currently has indoor air quality issues If no indoor air quality issues are detected installing ventilation is not required Thanks Answer Let s begin by quoting the Ventilation action required by DOE Weatherization Program Notice WPN 11 6 January 12 2011 2010 or most current ASHRAE 62 2 is required to be met to the fullest extent possible when performing weatherization activity Implementing ASHRAE 62 2 is not required where acceptable indoor air quality already exists as defined by ASHRAE 62 2 Existing fans and blower systems should be updated if not adequate ASHRAE 62 2 2010 defines acceptable indoor air quality IAQ as air toward which a substantial majority of occupants express no dissatisfaction with respect to odor and sensory irritation and in which there are not likely to be contaminants at concentrations that are known to pose a health risk page 3 Determining unacceptable indoor air quality can occasionally be quite simple but it is usually challenging If the air in a house is reeking of cat urine it is unacceptable We all know this it s simple If the water heater is spilling causing 200 ppm of carbon monoxide to enter the home it is unacceptable If a waste pipe has broken in the basement it is unacceptable High polluting events are usually pretty easy to detect not in the case of carbon monoxide or radon and fix Our health and safety protocols are set up to find and correct such issues ASHRAE 62 2 is not intended to address these high polluting events The challenges are the more typical cases that might include mold and mildew formaldehyde emitted from kitchen cabinets or volatile organic compounds VOCs from carpets paint and household cleaners Weatherization personnel do not have the equipment or protocols to detect these problems ASHRAE 62 2 is intended to mitigate these types of pollution by diluting the household air with fresh outdoor air whole building ventilation and eliminating some pollution at its source local bathroom and kitchen ventilation We expect DOE was aware of this when policy makers adopted the use of 62 2 for Weatherization Both the definition of acceptable IAQ in ASHRAE 62 2 and the full WPN 11 6 acknowledge that there are many contaminants beyond mold and mildew formaldehyde and VOCs that might be of concern These include but may not be limited to radon carbon monoxide and carbon dioxide The Ventilation statement in the WPN 11 6 allows agencies to avoid the prescriptive requirement of installing a fan if they can demonstrate acceptable IAQ on a performance basis However it is our interpretation that this demonstration is not fulfilled by a subjective assessment by an auditor Rather it must be an objective assessment that holds up to questioning Essentially if you don t want to install a fan prove why it is not needed Otherwise don t try to subjectively assess whether each home meets the definition of acceptable IAQ but instead implement the prescriptive 62 2 ventilation Interviews with the client should not be used to assess whether a home has acceptable indoor air quality One reason is that expressed dissatisfaction is only a part of the definition of acceptable IAQ and there are pollutants that clients cannot sense which are likely to increase in concentration following weatherization if ventilation is not added A second reason is that the responses from clients will be based on pre weatherization rather than post weatherization conditions The Wisconsin Weatherization Program has been using ASHRAE 62 2 since 2004 and as a result has installed thousands of ventilation systems in low income homes Their auditors use the appropriate ASHRAE 62 2 calculations for every job to determine whether to install ventilation rather than making a subjective determination about indoor air quality This is the safe way to proceed at least until a sure fire and inexpensive method of determining indoor air quality is found Rick Karg with the generous and expert help of Paul Francisco Both are members of the ASHRAE 62 2 committee From Randall Olsen Category Monitoring Subject Kneewall Insulation Question We have long required all kneewall insulation to be covered with a housewrap Tyvek etc We believe this has to do with possible wind washing reducing the thermal performance of the insullation batt non human contact area We request your expert opinion and thoughts on installing housewrap over kneewall insulation Thank you Answer Yes it is always a good idea to cover insulation in a manner that air movement cannot degrade the R Value it also helps keep pests out of the insulation Covering it with house wrap will work We use John Mannsville comfort therm R 19 or R 13 It is a poly encased fiberglass batt We choose to do that as it saves us the labor of installing the house wrap However your method is absolutely acceptable Cal Steiner From Kevin Simonson Category Technical Tools Subject Core Sampling of Sidewall Insulation Question We are supposed to take core samples to verify density of sidewall insulation What is the weight of the sample supposed to be What tools are needed Is there an industry standard for core sampling We are supposed to have 3 4 lbs per cubic foot Answer The important reasons to dense pack insulation are to reduce air leakage through the cavity and to prevent settling Core sampling can verify the proper density was installed and it can serve as a great training tool I have probably done from 200 to 300 core samples on walls where cellulose was blown I have found it to be a great technique but it has limitations Core sampling will give a reliable value for insulation density but only where the sample is taken this is important to keep in mind The core sample at 3 feet above the floor might be 3 5 pounds ft3 but at 7 feet above there might be little or no insulation The density of cellulose insulation determined by the core sampling should be from 3 25 to 4 5 pounds ft3 from 3 5 to 4 pounds ft3 is just right If you are measuring another type of insulation the ideal density will be different Blown fiberglass for example should have a density of 2 pounds ft3 or more Unfortunately a core sampling kit must be pieced together I don t know of any commercially available kits you can purchase You can find the parts required for a core sampling kit on my website at http www karg com pdf Insulaton density Core Sample Kit document pdf Instructions for the use of the kit are included The core I have always used is 2 inch diameter Drain Waste and Vent DWS copper tubing 12 inches long Others use different cores or tubes for extracting the insulation sample Whatever you use for the core it is important that your density equivalency table be based on the exact inside diameter of the core For the core I use you can find the density table at http www karg com pdf Insulaton density Core sample chart pdf This chart is ONLY for cellulose not for fiberglass I am not aware of an industry standard for core sampling installed insulation A few quality control experts have told me that in order to get a reliable idea of whether the walls of a house are adequately dense packed we would have to take about 30 core samples Of course for day to day weatherization operations this is not possible Don t ever take a core sample at or within 2 feet of the fill hole where the insulation was blown in What matters is the density further away from the fill hole the density 3 to 6 feet from the fill hole demonstrates the skill of the installers and the quality of their equipment There are a few other methods for checking density that are easier than core sampling but not as precise Because I have never checked the density of blown fiberglass I am limiting my suggestions to cellulose First the finger or digit method Drill a hole in the exterior wall sheathing to expose the blown cellulose If your index finger is able to penetrate the blown cellulose it is not adequately packed probably less than 3 5 pounds ft3 This doesn t give you a density value but it is quick Another simple method was devised by Andy Cordova in Colorado it s ingenious I call it the twisty thing This simple tool is a piece of heavy wire heavier than a coat hanger similar to the gauge of the wire used to hold up fiberglass batts under floors 15 inches long At one end put a bend at a right angle to create a 3 inch long leg Do the same at the other end but put the 3 inch leg in the opposite direction After the bending is complete you have a 3 inch leg at each end pointing in opposite directions with a 9 inch straight piece connecting the
