Alexander Bell replied to Jack Baikoff's discussion Just how much does adding air barrier to a knee wall insulation increase it's performance?
"Here is a chart from a presentation by Steve Easley.  I would like to see the data but this gives some insight to your question. "

Alexander Bell replied to Craig Bird's discussion Insulating a garage in hot dry climate?
"I think your first sentence of this post clarifies what you intended but did not say in the OP - insulating only the ceiling. I think the garage door is the first choice.  Second would be the ceiling and third the walls.  If this is an…"

Alexander Bell replied to Bob Blanchette's discussion Problem Room on North Side of House
"From looking at the pictures (inside and out) the likelihood is that this ceiling assembly is too shallow and has less (possibly R-19) while the rest of the building has R-30 or more.  Add to that the probability that the soffit venting is…"

Alexander Bell replied to Alan Meier's discussion Folk Labeling of energy controls - request for photos
"I have newly built house with a switch box (4g) served by two circuits (one is part of a 3 way).  I think it is lazy planning, or inexperienced installers, plus your code inspectors will never spend the amount of time at a house to actually…"

Alexander Bell replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?
"This was a project that was supposed to be a demo, HQ project.  I think they made some mistakes and probably took on too much with little experience in EE building.  It falied the Thermal Bypass inspection for Energy Star and they did…"

Alexander Bell replied to Joel Greenberg's discussion The Truth About Windows? in the group Weatherization
"If you look closely at the inputs for Manual J in Wrightsoft; exterior storm windows provide some benefit. Example: single glaze wood SHCG w/o storm 0.64 SHCG w/storm 0.56 U-val w/o storm 0.90 U-val w/storm 0.57   Example: double glaze…"

Alexander Bell replied to Mark Bradley's discussion Does anyone have any experience with an Owens Corning product called "Energy Complete" ?
"I have seen it in use on one job and was under-whelmed by the actual installation.  The demo card shows a nice thick gasket-like application; what I observed was closet to paint, and left me doubting it would have the desired sealing between…"

Alexander Bell replied to John Poole's discussion Historic Windows: UV and Thermal Transfer in the group Historic Home
"Why no mention of interior storm windows.  They seem to be better than exterior units in many respects.  I have no hands on experience, but the info available on the web seems to make a compelling case.   Anybody with first hand…"

Alexander Bell replied to Jerry Adlon's discussion IS ATTIC VENTING NECESSARY IN ST. LOUIS, MISSOURI?
"If I understand the situation, unless they added blocking between the roof trusses at the roof sheathing, the fiberglass insulation will slow the movement of the air, but certainly not stop it.  Unless the air-sealing has been done, it sounds…"

Alexander Bell replied to George M. Matthews's discussion Blowing smoke - into ducts to find leaks
"I have not found it to be very helpful and have tried on a number of occasions with a  theatrical fog machine.  If it is a big leak or at the air handler, then you can see some smoke.  If the leaks are at fittings and connections, by…"
