50mm Celotex GA4050 PIR Insulation Board 2400mm x 1200mm

What Is 50mm Celotex GA4050?

Keep the desired temperature in your house all year round with 50mm Celotex GA4050 PIR Insulation; a general application board suitable for floor, wall, and roof applications. 

50mm Celotex boards are manufactured using a blowing agent that has zero ozone depletion potential (ODP) and low global warming potential (GWP) making it an eco and green-friendly insulation solution. 

These high-performance 2.4m x 1.2m PIR boards are BBA certified and feature low-emissivity foil facings that give improved thermal insulation performance in sealed cavity air spaces, improving the thermal envelope of your home. 

Among its other product features are excellent water vapour resistance and reasonable compressive strength. 

50mm Celotex GA4050 PIR Applications

As a general application ('GA') insulation board, this BBA certified PIR insulation board is suitable for roof, floor, and wall applications.

This includes pitched roofs, flat roofs, solid masonry walls, partition wall, timber frames, and steel-framed systems, specifically timber frame internal linings, solid masonry internal linings and between timber joists.

BS EN is British and European Standard Specifications. With over 100 years of experience, the British Standards Institute is recognised as the UK’s National standards body.

• Spread of flame: Euroclass E Reaction to Fire classification, according to BS EN 13501-1
• Thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value - BS EN 12667
• Compressive strength: ≥140kPa - BS EN 826
• BRE Green Guide Rating of A for sustainability - which can assist in demonstrating environmental performance in your BREEAM assessments
• BBA certified

50mm Celotex GA4050 Storage & Handling

As they are super light and portable, 50mm Celotex boards can also be handled and transported easily; making them a doddle to install. If you need to store 50mm Celotex GA4050 boards for a while before installation, you should choose a cool, dry space.

Our rule of thumb when it comes to storage is that the boards should not be stored on the ground. Instead, pop them on a level surface and under a protective cover, just for good measure.
