I had Vipeq cork spray applied about 3 years ago, to my 1950’s double brick bungalow, which had no insulation. Vipeq had many colors to choose from, I picked my color and had it applied and it was done quickly and efficiently. Since Vipeq sprayed my home it is warmer in the winter and cooler in the summer. My furnace also picked up about 2 degrees. When it’s hot outside, it’s cool inside my home. When it’s cold outside, it’s warm inside my home. The cork spray doesn’t allow the transfer of heat or cold. I had great results!!
