Under Slab Insulation


Specifically designed to withstand the weight of a concrete slab and the rigors of foot traffic. Prodex exhibits less than 9% compression in thickness when subjected to loads associated with standard concrete floor systems. (Note: The amount of pressure under a typical four inch concrete slab section is less than one pound per square foot).

With a perm rating of less than 0.1, this class 1 vapor barrier excels in water protection. It is also ideal for retarding the passing of soil gasses such as radon into your home. The reinforced foil sheet also serves to prevents the passing of termites.

Benefits of this under concrete insulation: Thermal break, durability, moisture resistance, low water vapor transmission, radon resistance, termite resistance and ease of installation.
