Product Description

Where thermal performance counts, depend on 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 Insulation Board Applications


As a general application insulation board, 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)


Celotex GA4075 Specifications


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

75mm Celotex Insulation 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 insulation 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.
