"Tyvek (tm) air barrier is sealed to the concrete and run up onto the sheathing before the foundation foam goes in. Then a z-flashing sits right on top of the foundation insulation, and is taped into the Tyvek. . And, this is Wisconsin.…"

"Don - thanks for the additional detail and design info. I do understand cost decisions (there is a current blog on Fine Homebuilding that speaks directly to that decision) and also wonder if ANY current mechanical devices have the longevity desired.…"

Don Hynek replied to Jack Baikoff's discussion Vermiculite in the fireplace
"Our weatherization protocol (based on Wisconsin DHS rules) says there is no reliable sampling protocol for asbestos  in vermiculite. The reason (I am told)  is that the asbestos fibers laid in veins in the original ore, and not dispersed…"

"You are probably right, but there were multiple levels of decision-making on the window issue. First of all, it was really hard to keep the Department of the Treasury (my wife) on line with simple Anderson 400 series windows. I finally had to…"

"Don,   Great response as I was sure that you had dealt with the issue.  Perhaps just posting your response to me would help to keep others out of trouble - - minus "I don't know if I can edit the original post -- do you think I…"

"Correct -- for cold climates. That's why this REMOTE system is ideal for retrofit in OLD cold-climate  houses, and for new construction anywhere. The key is that the sheathing (the outermost wood layer) is the "break point." The…"

"Don,  As I mentioned in another forum, the foil vapor retarder (covering the insulation) on the exterior of the building could be a problem in some instances - - especially with any type of interior vapor retarder (paint, foil, etc.).…"

"Don, Placing horizontal R-10 slightly sloping away from the building (for drainage purposes) and near the bottom (not below) of the 1'-0" vertical insulation on your foundation walls would help immensely.  I understand that such…"

"Don - Good work! Can you add more detail to what windows/doors you used? Maybe one of the reasons you did not test out as tight as expected was the use of double-hung windows (I see nine in the above photo which is just 2 sides) versus…"

"to derate a furnace takes a very good teck.   Top 10% teck  and a master in combustion.   In Kansas City there is less than 50.   Most maker of furnaces do not want derating done.  If you need 4-5 ton AC but just 40,000…"

"derate the furnace then test with a flue gas meter.   I find most nat gas and LP gas furnaces are 3-4 times over sized.   After the building is sealed and R-60 is added -  most gas furnaces will go off high limit with low air flow and…"

"Well, the roof is the one weak spot left. The flat attic areas (center of house and above the dormers) are R-60 loose-fill cellulose, but the four slopes are 2x4 rafters with dense-pack cellulose. The slopes still melt snow in a hurry. And I…"
