Insulating Basement Walls with FOAMAX

Dec 10, 2020

Welcome to the 80th episode of Dr. Energy Saver’s On the Job Video Series!

This episode is all about the importance of basement wall insulation in home comfort and energy savings. Basements are a subject that Larry Janesky, owner and founder of Dr. Energy Saver, knows very well. After all, he’s been in the basement waterproofing business for over 20 years as the owner and founder of Basement Systems — the world’s leading basement waterproofing network. In this video he explains why basements are so damp and cold, and how much impact an uninsulated basement can have on the comfort of your home and your energy bills.

The concrete walls in the basement are very dense and cold year-round. The ground is cold and during the winter, the outside air is equally cold. According to the laws of thermodynamics, heat tends to travel from more to less. That means that a significant portion of heat produced by your boiler or furnace will tend to escape to the outside through the basement walls — a problem that Larry demonstrates using thermal imaging. Watch the results in the thermal imaging camera as the basement walls are insulated with FOAMAX.

FOAMAX is a special type of polyisocyanurate rigid foam insulation board that is especially suited for basement walls. It has a high R-Value per inch, and — unlike other types of rigid foam — it can be left exposed in a basement. FOAMAX is also waterproof and acts as a vapor barrier, directing any wall seepage to the perimeter drain system installed down below.
