Insulating Exterior Walls with AirKrete (Short Version)

Dr. Energy Saver recently performed a number of energy-saving improvements in this ranch-style home to help lower energy bills and increase overall interior comfort.

In this "On The Job" episode, Larry Janesky, owner and founder of Dr. Energy Saver, demonstrates how they air sealed and increased the R-Value of existing walls using a new injection foam product called AirKrete.

A lot of energy was being lost through the walls of this home, because the walls were insulated with fiberglass batts, which do not stop air flow. There was no tar paper or Tyvec liner on the exterior of the walls to act as a wind breaker so the air was flowing right through them.

AirKrete foam insulation was injected in the existing walls, through small holes drilled on the outside, to access the wall cavities. AirKrete is a 100% inorganic and environmentally-friendly foam insulation product that has an excellent R-4 value per inch significantly increasing the insulating performance of the existing walls. Its consistency is similar to that of shaving cream, which allows the foam to completely fill the wall cavity and any existing gaps; air sealing and insulating the wall at the same time.

AirKrete is free of harsh, volatile chemicals and does not produce smelly or toxic fumes before, during or after application. In fact you can't smell AirKrete at all.

Perhaps one of the most beneficial characteristics of AirKrete is its fire rating, especially when compared to fiberglass. To see a demonstration of the material's impressive fire resistance, watch the complete version of the AirKrete video.
