Effect of Moisture
POLYFOAM is generally resistent to moisture gain.

Uses in Construction
Concrete slab-on-ground floors
POLYFOAM in various thicknesses can be used as an insulation material in slab-on-ground concrete slabs.
Best practice suggests that a minimum of 60mm S grade POLYFOAM sheet is laid on top of the DPM, sand blinding and hardfill before the reinforcing is laid and concrete is poured. The R value of 60mm S grade POLYFOAM is approximately 1.6 plus the additional R value of the concrete.
When to use Poyfoam in a concrete slab?
Adding Polyfoam insulation into a concrete floor is particulary important:-
for small floor slabs (<80m2),
when heating elements are incorporated into the slab,
when the water table beneath the slab is less than 1 m below the surface,
when the slab is designed to act as a thermal store for solar heat gain
Architectural Shapes
POLYFOAM is very easily cut into architectural shapes that can be used to enhance the look of your home.
Cavity Insulation
POLYFOAM is an ideal insulating material for the cavity in timber framing construction or as a core in insulated panel. It can also be use as a core in concrete tilt slab panels or in the ceiling spaces.
Exterior Insulated Finishing Systems (EIFS)
POLYFOAM has is an excellent cladding for EIFS rendered plaster finishes.
Lightweight construction material
POLYFOAM is great for formwork.
It can be used as protective sheet anywhere
Protection from backfill and water run off
A layer of POLYFOAM will protect blockwork and applied waterproofing mebrames from potential damage.
The impervious nature of EPS will assist in deflecting water and runoff away from the building.
