75mm Celotex GA4075 PIR Insulation Board 2400mm x 1200mm

What Is 75mm Celotex GA4075?

Where thermal performance counts, depend on 75mm Celotex GA4075 thermal insulation board. 

These high-performance 2.4m x 1.2m PIR boards feature low-emissivity foil facings that give improved thermal insulation performance in sealed cavity air spaces. 

With a thermal conductivity as low as 0.022 W/mK, the boards do an excellent job of retaining heat within a building structure without compromising building regulations or internal floor or wall space.

In terms of its composition, 75mm Celotex GA4075 comprises a rigid foam core and is manufactured using a blowing agent that is free of ozone depletion potential and low global warming impact - promising high thermal results without enervating the environment.

Suitable for floor, wall (partition wall/solid masonry wall), and roof insulation, 75mm Celotex GA4075 thermal insulation solution offers excellent water vapour resistance as well as a reasonable compressive strength of 140kPa. 

75mm Celotex GA4075 PIR Applications

As a general application insulation board, 75mm Celotex GA4075 is suitable for roof, floor, and wall insulation in both residential and commercial properties. 

Equipped with an innovative low emissivity foil facing and manufactured from tough polyisocyanurate (PIR), the boards are easy to cut and shape for application in pitched roofs, solid masonry walls, partition walls, timber frames, and steel-framed systems, specifically timber frame internal linings, solid masonry internal linings and between timber joists. 

It can also be used as floor insulation in solid floor systems such as screed and concrete slab floors, and as loft insulation between timber rafters.

Celotex GA4075 is suitable for the following applications:

• Pitched roofs
• Solid masonry walls
• Timber frames & steel framed systems
• Timber frame internal linings
• Floors - screed, concrete slab and timber joist floors
• Ground floors
• Loft insulation – between and over timber joists (pitched roof)
• Timber frame sheathing (external wall)
• Between timber frame studs (external wall)
• Solid masonry internal linings (external wall)

75mm Celotex GA4075 Specifications

This 75mm Celotex rigid PIR insulation board can achieve low U-Value with just a single layer of insulation. 

Available in 2.4m x 1.2m, GA4075 insulation board can improve the thermal envelope of your home better than almost any other material on the market; with an outstanding thermal conductivity of 0.022 W/m.K, PIR is second only to phenolic insulation in terms of thermal conductivity.

75mm Celotex GA4075 Storage & Handling

As they are super light and portable, 75mm Celotex boards can also be handled and transported easily. If you need to store 75mm Celotex GA4075 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, keep them on a level surface and under a protective cover. 

About Celotex

Celotex is a leading British manufacturer of 75mm thickness PIR insulation. Founded in the early 1920s, the company has since evolved from a fibreboard insulation company to one that solely focuses on PIR insulation boards.

The GA4075 insulation board is just one of many popular thermal insulation solutions in the Celotex product range. It comes from the GA4000 product group, which includes 6 other thicknesses; 50mm (GA4050), 60mm (GA4060), 70mm(GA4070), 80mm (GA4080), 90mm (GA4090) and 100mm (GA4100).
