Fire Resistant Insulation

About

Fire Resistant Insulation Types Fire resistant and fireproof insulation is designed to resist the spread of flames, limit smoke emission, and in the case of stone and glass mineral wool, achieve full non-combustibility. It is used in walls, partitions, floors, loft conversions, and cavity walls in domestic and commercial buildings, and is increasingly specified following changes to UK fire safety legislation. Insulation UK stocks a comprehensive range of fireproof insulation materials from Rockwool, Knauf, Superglass, and Tekfon, with competitive trade pricing and fast UK-wide delivery on every order. Rockwool Fireproof Insulation All Rockwool products are Euroclass A1 non-combustible and deliver combined thermal, acoustic, and fire performance in a single product. Rockwool RWA45 (45kg/m³, lambda 0.036 W/mK) is the UK's most widely specified acoustic and fire resistant slab, available from 25mm to 100mm in 1200 x 600mm format. It friction-fits between timber studs and floor joists and is the standard choice for party walls, separating floors, and acoustic partitions where fire resistance is required. Rockwool RW3 is a higher density slab for applications demanding both maximum acoustic performance and fire resistance, available from 25mm to 100mm. Rockwool Flexi is a multi-purpose stone wool slab with a flexible edge for a tight friction-fit without cutting. Available in 400mm and 600mm widths from 50mm to 100mm, it has been specifically tested to provide 60 minutes fire resistance for loft conversion floors, allowing existing ceilings to be retained while meeting Building Regulations for habitable loft space. Knauf Rocksilk Fire Resistant Insulation Knauf Rocksilk is a range of rock mineral wool slabs, all Euroclass A1 rated and manufactured with ECOSE Technology. Five density grades are stocked, from RS45 through to RS140, covering general building applications through to high-specification commercial acoustic and fire requirements. RS45 and RS60 are the most comm
