I have seen a performance curve for fiberglass insulation in the past but have not seen anything for other types of insulation. This curve plotted R-values vs. temperature. I'd like to compare the different materials side by side to better inform customers. If I remember correctly the fiberglass curve looked like a bell curve with its greatest value at 55 degrees. Does a comparison study exist?

Thanks

I am working on a repair project. My clients had a pipe burst causing damage to a wall, ceiling and floor in their living room. Currently, the room is carpeted. Under the carpet (adhered directly to the beautiful 1 1/2" original oak flooring) someone laid sheet vinyl. We wondered if this 60's era vinyl might contain asbestos and had it tested - the backing does contain asbestos. Our option seem to be: 1. Have a certified asbestos removal company remove the entire floor (oak and all) and start from scratch or 2.

I am residing a 30 year old house in North Jersey. In order to match the exisiting house I need to add about 1 and 3/4 inch filler over the 1/2 plywood sheathing to some exterior walls before reinstalling vinyl siding.

Over the 1/2 plywood, I have been using using 1 inch unfaced expanded poly (i remove the plastic backer as I dont know if that is permiable) then use 3/4 extruded poly (I punch about 100 nail holes first to ensure it breaths)

THere is no vapor barrier inside other than standard r 11 fraft faced insulation

So my questions are,

Equipment with two motors with 8" diameter provision for exhaust system. It is OK if I'm going to use Y connector ( g.i. sheet ) with 10" diameter and 2-8" diameter and split them with flexible duct? Existing supply for exhaust system is 12" diameter.

I am building a new home to PassivHaus standards, while undergoing LEED certification. The LEED section on ventilation pertaining to kitchens seems unclear to me. We are providing ventilation of the kitchen via an HRV, but we couldn't possibly tie in the ventilation unit that comes with the cook top (downdraft) as it uses a 600cfm motor. We instead were going to tie in the downdraft to a filtered recirculation unit.
