Floor Insulation Systems

 
Under Concrete Floor
Where a regularly used concrete floor is to be poured on grade or in a basement use PlastiSpan® insulation board installed in adequate thickness under the floor before pouring. A vapour barrier should be placed between the insulation layer and the underside of the concrete slab. The floor surface will be noticeably warmer to anyone standing on the floor.

Over Concrete Floor
Place PlastiSpan insulation boards above concrete slab-on-grade to make the floor surface temperature noticeably warmer.

PlastiSpan insulation boards of adequate thickness placed above the floor slab and on the interior surface of the foundation wall will raise the surface temperature to within 3°C (5°F) of the room temperature under normal conditions.

This system uses wood nailers with insulation boards between them and a panel overlay which serves as the base for flooring.
