70mm Celotex GA4070 PIR Insulation Board Applications

This BBA certified multi-purpose insulation board is suitable for roof, floor, and wall applications. Equipped with an innovative low emissivity foil facing and manufactured from rigid 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 GA4070 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)

Celotex GA4070 Specifications

This Celotex rigid PIR insulation board can achieve low U-Value with just a single layer of insulation whilst offering an outstanding thermal conductivity of 0.022 W/m.K. Available in 2.4m x 1.2m, GA4070 insulation board can improve the thermal envelope of your home better than almost any other material on the market; PIR is second only to phenolic insulation in terms of thermal conductivity.

The board is manufactured from tough polyisocyanurate, with an ideal mix of blowing agents acquiring zero ozone depletion potential and a low global warming impact - meaning it is gentle on the environment. 

Let's have a look at the specs:

• Suitable for use in a number of applications including roof, wall and floor systems
• Thermal conductivity of 0.022 W/mK
• Moisture-resistant
• Low Global Warming Potential (GWP) and Zero Ozone Depleting Potential (ODP)
• Achieves an A+ rating when compared to the BRE Green Guide 2008
• Features low emissivity foil facings giving improved thermal insulation performance within cavity air spaces
• Easy to cut and shape
• Provides reliable long-term energy savings for buildings

About Celotex

Celotex is a leading British manufacturer of 70mm 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 GA4070 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), 75mm (GA4075), 80mm (GA4080), 90mm (GA4090) and 100mm (GA4100).

70mm Celotex Insulation Storage & Handling

As they are super light and portable, 70mm Celotex boards can also be handled and transported easily; making them a doddle to install. If you need to store 70mm 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, pop them on a level surface and under a protective cover, just for good measure.
