As a design-builder in Cape Cod, MA, where we have a good deal of water issues, I have to say you are all wet and number of your claims. The BigBoss is right on about cellulose. Fiberglass insulation is a thing of the past and the quicker everyone gets off that bandwagon the better. We spend our money on rigid insulation over the exterior sheathing to really eliminate any heat loss from the walls then blow in cellulose inside the walls. Spray soy foam in the ceilings and rafter spaces to eliminate venting the roofs at all (again no heat loss).The Bluejean insulation is meant for walls, not meant for ceilings our wherever you have it in the picture. Tight homes are good, and i venture to say if you're not building tight homes in Canada....well nuff said on that.
Any green is good, moving away from the old inefficient ways needs to happen now, not later.
