can't believe I'm actually supporting a 'radiant barrier' application, but if any one works, this is probably as good of application as can be had. Thermax applied and then strapping on top, you gain the bit of thermal insulation of the reflective surface and air space combo. you do something and then realize why/how your method or shortcut doesn't work. The strapping has to be fastened much like the drywall, so not sure of the benefit (although there may very well be one that is hidden from our view. What about strapping over the rigid insulation, then screwing into that?. I'll check out the building science website. We have it on the ceiling, but I'm afraid I didn't seal up the overlaps with foil tape. We put up a vapor barrier after the insulation went in. When the temperatures really dip those bands are often times ice.

We do tend to get large bands of condensation on our windows when the weather turns colder. Should I go around with some "great stuff" and start sealing up these areas? I'm assuming this is better to use than fiberglass? I just need to be careful on how much I fill the drilled or cut out holes. When will contractors be required to be licensed to build and remodel houses?Īnyway, I just looked down in the basement and indeed, none of our heating pipes, drain pipes, or the plumbing vent are sealed. I'm afraid when we put this house back together (we had to gut the entire house when we bought it) 12 years ago, we had a builder who didn't do us any favors a great guy, but his building practices have something to be desired. Most of our upstairs is unfinished, but we would like to put things in motion to get it finished. The dormer area has insulation, vapor barrier, 1inch foam insulation, then sheetrock. So,after the insulation was installed we put in a 6mil vapor barrier, then strapping on the ceiling, then sheetrock. Unfortunately he only built it out about 4-6 inches, so it isn’t far enough out to maximize venting.
When we bought the house there was no soffit, so we had the contractor build one out. The proper vents aren’t out to the roof edge and don’t fill the cavity between rafters enough. The dormers and steeper roof pitches have a R-19 insulation in them. The attic space (such as it is) has 2 layers of R-15 in it – running in opposite directions. We’ve had some major problems with ice dams over the years since we bought the house. The rafters are only 2×6’s as are the ceiling joists.

Unfortunately I found out recently we didn’t install the vents correctly and also didn’t add enough insulation. My partner and I put in all of the proper vents and insulation ourselves.
