SpeedDeck has launched an insulated structural cassette roofing system called SpeedForm

The prefabricated sections are lifted into place on site to provide the structural element of the roof, which SpeedDeck says cuts build times and costs and reduces the need for working at height.

The system can be used for all roofing applications and supports most roof systems. It is built around EcoJoist’s open-web product and incorporates 305mm or 425mm of

non-combustible glass wool primary insulation with rock fibre infill insulation. The panels are faced with 11mm OSB to the top and a 0.7mm polyester-coated steel WalkLiner on the underside. The company says the design ensures an airtight roof with a low U-value (0.143 W/m2K for 425mm thick insulation) and spans of up

to 8.5m. U-values can be further cut to 0.122 W/m2K by adding 50mm of PIR insulation on site.
