Extruded polystyrene (XPS) insulation for flooring and flat roof applications

Through its Floorboard and Roofboard ranges, Polyfoam XPS Ltd offers high quality, high performance, rigid, closed cell, extruded polystyrene (XPS) insulation for use in domestic, commercial and industrial buildings alike.

XPS insulation is moisture tolerant, meaning it can be installed in damp or wet environments, and has a high compressive strength. These qualities make it the perfect choice for inverted flat roofs, below concrete floor slabs and to the outside of basement structures.

Providing a flat, strong and dimensionally stable insulation layer, XPS is also a robust solution for conventional warm flat roofs, green and blue roofs, car park decks, floating floors above the ground floor slab, and swimming pool basins.

It is compatible with underfloor heating systems at ground and intermediate floor level, can provide external wall insulation below the damp proof course in low-energy construction projects, and is suitable for use with a variety of building boards and materials to create thermal laminate products.

Polyfoam XPS credentials

Polyfoam XPS Ltd is a leading manufacturer of closed cell, extruded polystyrene insulation. The Polyfoam range is lightweight, strong, moisture resistant and easy to cut and shape, providing thermal performance and strength for the lifetime of the building.

Manufactured in the UK using a blowing agent with low global warming potential (GWP) and zero ozone depletion potential (ODP), Polyfoam XPS products are free from CFCs and HCFCs.

They have Environmental Product Declarations (EPDs) and raw material procurement is certified to BES 6001 (Responsible Sourcing of Construction Products).

The Polyfoam XPS factory in Hartlepool has been assessed as operating under an ISO 9001:2015 Quality Management System, an ISO 14001:2015 Environmental Management System, an ISO 50001 Energy Management System, and an ISO 45001 Occupational Health & Safety Management System.

Both the flooring and roofing systems benefit from BBA Agrément certification.

Benefits of Polyfoam XPS insulation

When you specify and install XPS insulation, you’re working with a material that is unique among widely-available thermal insulation materials for its tolerance of damp or wet environments. That means it can be installed external to below ground structures, and below ground floor slabs, with no detriment to the performance of the product over the life of the building.

It offers the opportunity to enclose below-ground building fabric within the thermal envelope, reducing linear thermal bridging at junctions between construction elements, and achieving a greater level of building performance, comfort and energy efficiency.

Thanks to its superior load-bearing performance, Polyfoam XPS insulation is a robust solution that will stand up to the demands of any construction site, delivering its intended thermal performance and contributing to a reduction in the performance gap once the building is finished and in use.
