Ed, I have finished my basement remodel – many months ago. I’m sorry it took so long to get back in touch with you. The installation was so easy.It took approximately 2 weekends to install and sheetrock. The basement had 2 x 4’s on their sides with paneling over top painted an ugly color. We demoed this first, then applied the InSoFast panels. We sheetrocked over the panels and painted.This WAS so easy! Our basement was always cool, but we’ve lowered the temperature by at least 10 degrees. In fact, we don’t use the A/C in the basement at all (been 100 outside for weeks). Our house was built in 1964. Love the product!
