There have been a lot of questions regarding the use of the “blankets” or wide bat insulation on concrete basement walls to meet the energy code requirements. (Without R-10 on concrete or masonry basement walls, it gets very difficult to get a res-check to pass compliance with the 09 IECC)
We have found that they are rated for R-10+ IF installed according to manufacturers specifications. Simply stapling it to the plate and draping it to the floor is NOT compliant.
The manufacturers we have been able to find require attachment to 2X2 fur strips run horizontal at the top, bottom and at intervals matching the width of the bats.
We would like to allow these types of systems IF PROPERLY INSTALLED to meet the insulation requirements of the Energy Conservation Code. When installed properly, the likelihood of removal 10 minutes after final inspection is much less.
If you don’t want them, please let us know why AND either, how you are getting R-10 on the basement walls OR how the res-checks are coming out without R-10 on the basement walls. Thanks, this is greatly appreciated!
