Cold climate wall

Started this discussion. Last reply by Don Hynek Jul 11, 2014. 2 Replies

I have heard Joe Lstriburek twice say that a wall in this climate (Albany NY, almost 6,000 DD) should have 1/3 of the R-value on the outside of the structure and 2/3 in the cavities to prevent…Continue

Concerning duct testing in crawlspaces (this is for new houses for Energy Star, but will be the same for existing houses):I have a house on a conditioned crawl with ducts in that crawl.  There is an…Continue

Ed Minch replied to Danny Gough's discussion Sealing Flex Duct Passing Through an Air Barrier
"Kent At least in the mid-Atlantic, there is no place in single family detached housing three stories and under that needs to be fire stopped.  There are plenty of areas needing fire BLOCKING, but not fire STOPPING, and single part foam is fine…"

Ed Minch replied to Danny Gough's discussion Sealing Flex Duct Passing Through an Air Barrier
"Danny When we find one of these (more and more rare these days) we use single part foam around the perimeter and are very generous with the amount. The hope is that it will compress the insulation enough to reduce any air leakage through that area.…"

Ed Minch replied to Tim Kendzia's discussion Cooling effect from solar panels
"Dennis I get what you are saying, but that makes R-13 batt insulation and an inch of styrofoam thermal bridges also - it's all just a matter of degree.  And room temp is effected by surface temps.  The closer to the interior air temp…"

Ed Minch replied to Tim Kendzia's discussion Cooling effect from solar panels
"Not sure the drywall being a thermal bridge pertains in this discussion - it is on the inside of a bunch of insulation and serves to add a bit of continuous R-value and provides airtightness.  What are the readings you are getting on the attic…"

Ed Minch replied to Tim Kendzia's discussion Cooling effect from solar panels
"I have used IR equipment in thousands of houses, both new and existing, since 1981, and my observation is that it does not matter what the temperature in the attic is, it matters what the temperature of the drywall surface inside is.   For the…"

Ed Minch replied to Gordon Smith's discussion Duct Cleaning? Good value or a waste of money?
""They are taken in by the return ducts and circulated around the home by the HVAC system. A regular duct cleaning can help reduce the number of these particulates building up and being pushed back into the home." If they are circulating…"

Ed Minch replied to Brett Little's discussion Virtual CEU Tour of the Pembroke Passive Solar Zero Energy Ready Home
"Bret Thanks - I also found the attachment that had more specs on it.  The windows are triple glazed - what are the numbers?  Is he really paying 3.6¢/kWh? Ed"

Ed Minch replied to Brett Little's discussion Virtual CEU Tour of the Pembroke Passive Solar Zero Energy Ready Home
"I sure wanted to know more about the wall and roof construction, type of insulation, window numbers, air sealing techniques, floor area, south facing and total window area. etc, etc. Also, something is wrong with the numbers.  At 13:35 of part…"

Ed Minch replied to Paul Raymer's discussion Stud cavity air returns
"I work with the State of DE on code language, and for 2012 there was was backlash from the HVAC guys about panned returns.  We managed to get language stating that they could be used only if the ducts are not required to be tested (i.e. all…"

Ed Minch replied to Paul Raymer's discussion Stud cavity air returns
"Has anyone documented mold inside a panned return?  We discourage the practice for different a reason.  We frequently see a 4 X 12 return grill = 48 in2 (less a bit for louvers), but the hole in the bottom plate of the wall is 2-1/2 X 10 =…"

Ed Minch replied to John Carton's discussion Insulation touches underside of roof in home with no soffit or soffit venting.
"I don't think it would be a problem provided there is no large source of interior moisture getting into the attic, especially in a cold climate.  With that in mind, a thorough sealing of the attic floor - including those plates at the…"

Ed Minch replied to Jerry Needham's discussion HVAC Question about running fan continuously VS setting on Auto so it runs when AC or furnace runs
"It all depends on the house - attic ducts, older unit, poor return capability - but I like the thermostats that have the "CIRC" circulate mode that operates the fan for only a portion of the time.  In my experience, it does the job…"

Ed Minch replied to Dav Camras's discussion Adding blown insulation to poorly installed batts?
"After lifting specific batts for blower-door/IR/experience guided air sealing, (rarely with 2 part foam) my crews will use a narrow rake to push batts down against the ceiling and around wiring and framing anomalies.  Then we will blow on top.…"

Ed Minch replied to Ed Minch's discussion Open return in the group Hall of Shame
"This is a return high on a cape cod knee wall after we took off the grill - the glove has a hand in it.  That is a supply duct running up through the return, and the angled roof above the knee wall attic visible through the hole"
