Under Concrete Insulation

Our insulation can be used under concrete slabs or flooring. It has been used under heated concrete floors for over 40 years.

It is so strong that some people drive semi trucks and trailers on the floors that are have the insulation under it. it has also been used under large walk-in large freezer units/refrigerqated warehouse floors.
