The BME has introduced a product developed by Tyz-all for window weatherization.  Easy to install and reuseable year after year.
The 4mill PVC plastic has a R value similar to a plate of window glass. The application of the window kit is to stop air infiltration from reaching the interior of your home.
Those cool breezes coming thru your old window frame are not just annoying but cost you money.  The BME Tyz-all window kit puts an end to it.
Weatherization kits are great for fund raisers also.   Click here for installation video.
