90mm Celotex GA4090 PIR Insulation Board 2400mm x 1200mm

What Is 90mm Celotex GA4090?

The benefits of home insulation range anywhere from reducing energy consumption to keeping your home toasty in the frosty winter season. 

90mm Celotex GA4090 multi-purpose insulation board are manufactured from tough polyisocyanurate (PIR) using a perfect mix of certain blowing agents which acquires zero ozone depletion potential (zero ODP) and a low global warming impact (GWP), making this general application insulation board the perfect choice for the eco-conscious. 

The 90mm Celotex board features low emissivity foil facings offering improved thermal insulation performance through their elimination of thermal bridges in sealed cavity air spaces. Celotex. 90mm Celotex GA4090 thermal insulation solution is suitable for floor, wall, and roof applications.

The most popular Celotex PIR general application insulation board in our range is 2400mm long and 1200mm wide. 

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, improving the thermal envelope of your home with an impressive thermal conductivity of 0.022 W/mK. 

Not only that, but they also offer excellent water vapour resistance and a reasonable compressive strength of 140kPa.

90mm Celotex GA4090 PIR Insulation Board Applications

This BBA certified PIR insulation board is suitable for roof, floor, and wall applications. is particularly effective at overcoming thermal bridging. 

The 90mm Celotex GA4090 insulation board eliminate thermal bridges by providing a continuous layer of rigid polyisocyanurate insulation within the building structure, providing long term energy savings and high thermal performance. 

The boards are suitable 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 GA4090 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
• 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)

90mm Celotex GA4090 Insulation Storage & Handling

As they are super light and portable, 90mm Celotex GA4090 boards can also be handled and transported easily; making them a doddle to install. If you need to store 90mm Celotex GA4090 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.

About Celotex

Celotex is a leading British manufacturer of 90mm 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 GA4090 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), 75mm(GA4075),80mm (GA4080) and 100mm (GA4100).
