High performance thermal insulation for residential and industrial building
Polyfoam XPS Ltd is a leading manufacturer of closed cell, extruded polystyrene insulation.
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.Â
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.
The versatile solution architects and homeowners have been looking for
Providing a flat, strong and dimensionally stable insulation layer, XPS is also a robust solution for conventional warm flat roofs, green roofs and blue roofs, car park decks, floating floors above the ground floor slab, and swimming pool basins.Â
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.
Quality insulation from the ground up and the top down
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.
Product applications
Polyfoam XPS is a versatile, unfaced insulation material that is suitable for numerous applications
The Polyfoam Orange Book is a comprehensive guide to extruded polystyrene (XPS) and its performance characteristics. There are also pages of application-specific design guidance for flat roofs, ground floors and basements, swimming pools, and cavity insulation below damp proof course (DPC).
