EXPOL CONCRETE FLOOR INSULATION

EXPOL’s range of under concrete floor (slab) insulation products provide thermal insulation and strength where it counts. Up to 10% of heat loss from a building is through the concrete slab. A building with underfloor insulation provides a warm, dry and healthy indoor environment for occupants, and reduces heating and cooling costs.

EXPOL ThermaSlab (EPS – Expanded Polystyrene), EXPOL Platinum Board (Graphite Infused EPS – Expanded Polystyrene) and  EXPOL-X (XPS Extruded Polystyrene) products won’t degrade over time, meaning thermal insulation performance is maintained for the life of the building. EXPOL concrete floor insulation is suitable for both residential and commercial building projects.

Compared to other insulation, EPS offers superior resistance to the ingress of water. Samples of EPS retrieved after 30 years in the ground showed less than 1% water content by volume. Boards periodically submerged over the same amount of time showed less than 4% water content.

The Products

EXPOL ThermaSlab S and H (EPS – Expanded Polystyrene) sheets are the most cost-effective products for insulating under a concrete slab. These densities will suit most residential floors and will achieve R values above building regulations.

EXPOL ThermaSlab VH (EPS – Expanded Polystyrene) sheets would normally be required in commercial applications where very high loads are probable. Also see EXPOL-X for these situations.

EXPOL Platinum Board (Graphite Infused EPS – Expanded Polystyrene) sheets are suitable for insulating under a concrete slab.EXPOL Platinum Board (Graphite Infused EPS – Expanded Polystyrene) is a premium product which achieves superior R values relative to thickness, commonly used when thickness is an issue or high R values are required.

Installation for:

EXPOL ThermaSlab VH (EPS – Expanded Polystyrene)
EXPOL Platinum Board (Graphite Infused EPS – Expanded Polystyrene)
EXPOL-X (XPS – Extruded Polystyrene)

The installation process of EXPOL concrete floor insulation is quick and easy. Simply butt the sheets together on top of the DPC (polythene). It is important that the polystyrene sheets are not placed under any footings or thickenings for load bearing walls.

The sheets can be taped together however this is not absolutely necessary. Once the sheets have been laid, place the reinforcing mesh on top using the required mesh chairs. See our Masterspec document for further information.
