My 40 foot sailboat is only about 100 ft2 of floor space, the surface area is more that of a mobile home - long and narrow, the hull and deck are about an R-5, the glass is all single pane, and there…Continue

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

John White replied to Ed Minch's discussion Heat and A/C on a boat
"Effective boat ventilation helps air to circulate areas as much as below decks and other areas. Fresh air in and the state air out. A single vent will now allow the air to flow. A minimum and two well-separated vents need to allow dry air to flow in…"

Heat and A/C on a boat

My 40 foot sailboat is only about 100 ft2 of floor space, the surface area is more that of a mobile home - long and narrow, the hull and deck are about an R-5, the glass is all single pane, and there are skylights and hatches that let in ALL of the sun, so how do you calculate the conditioning needs for winter and summer?  Tricky and lots of rule of thumb going on, but here is an interesting article that uses all the techniques we have for homes:…See More

This House has some CRAZY Insulation Details

"I like the  piece of Advantek at the top of the wall to connect the exterior sheathing with the drywall ceiling. With an R-9 airtight exterior sheathing, the flash of foam on the inside becomes much less important. I have had to air seal the…"

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
