FLOORMATE 300-A insulation awarded BBA accreditation

FLOORMATE 300-A extruded polystyrene (XPS) insulation from Dow Building Solutions has been awarded a BBA certificate, offering specifiers valuable third party endorsement for the product’s performance.

FLOORMATE 300-A - which is a STYROFOAM-A grade manufactured in the UK - is durable enough to be laid beneath concrete floor slabs, and can help to prevent thermal bridges at floor and wall junctions.

Thermal conductivity is 0.034W/mK in a 100mm thickness; the product also offers good compressive strength of 300kPa and a high design load of 130kPa. In addition, FLOORMATE 300-A has excellent moisture resistance thanks to its closed cell structure, making it suitable for a range of external insulation applications.

“FLOORMATE 300-A is a great choice for designers aiming for an ‘envelope’ of continuous external insulation that minimises heat loss, because thanks to its high strength and moisture resistance it can be used below the slab,” explained Steve Johnson, Technical Sales Manager for Dow Building Solutions.

“This BBA endorsement offers specifiers extra confidence that it can safely be used in such floor designs, and that when installed with the overlays specified in the certificate will remain effective as an insulating material for the life of the building in which it is incorporated.”

With a range of single, extruded thickness up to 200mm, the FLOORMATE 300-A boards are lightweight yet robust, offering durability across a range of domestic and medium load bearing floor constructions.
