  1. Thermo-Tech Windows of Sauk Rapids MN, we have also submitted our formal proposal to the DOE to participate in the R-5 program with high hopes also that this program will help sale more of the higher efficient windows. With this program our hope is not only will this entice current home owners to purchase the R-5 windows but also the new construction housing industry to take notice and incorporate more efficient windows in their projects as housing does make a come back. We have been producing a R-5 for over 2 years now and have had a medicore response due alot to the cost of this product so this program should end up being a big plus.
