Celotex GA4000 PIR Insulation Board 75mm (2.88m²)
SKU: 227271
Product Description
Celotex GA4000 is an easy to install polyisocyanurate (PIR) thermal insulation board with a low emissivity foil facing, available in thicknesses from 50mm to 100mm for roof, wall and floor applications.
Celotex GA4000 is a rigid polyisocyanurate (PIR) thermal insulation board with low emissivity foil facings on both sides. It is supplied as a 2400 x 1200 mm board with straight edges and can be considered for a wide range of roof, wall and floor applications. With a declared thermal conductivity of 0.022 W/m·K and thicknesses from 50 mm to 100 mm, GA4000 provides good thermal performance to help achieve target U-values with relatively slim build-ups.
The product is BBA certified for defined pitched roof, dry lining and floor applications and manufactured under independently monitored quality and environmental management systems in line with EN ISO 9001 and EN ISO 14001.
- Lightweight 2400 x 1200 mm PIR insulation boards.
- Low emissivity foil facings on both sides.
- Declared thermal conductivity 0.022 W/m·K.
- BBA certified for defined roof, wall and floor applications.
Typical applications
Pitched roofs (between rafters, between and under rafters, between and over rafters, loft insulation, sarking); Flat roofs (balconies and terraces, between and under joists); External walls (timber frame walls); Ground floors (beam and block floors, concrete slab ground floors, upgrading existing slabs, suspended timber floors).
