Celotex GA4075 is a high-performance multi-purpose insulation board that can be utilised in all sorts of applications, such as flat roofs, pitched roofs, solid floors and masonry walls as well as timber framed and steel framed systems. It's equipped with an innovative low emissivity foil facing and manufactured from rigid polyisocyanurate (PIR), so it's convenient and easy to cut and shape. This endlessly versatile insulation board boasts highly impressive thermal conductivity of 0.022 W/m.K for excellent thermal performance. So, it's able to easily meet the target U-value while being thinner than most similar products on the market.
And that's not all! The low emissivity foil facing dramatically improves thermal performance in sealed cavity air spaces, helping raise the potential U-value even further. The GA4075 is manufactured to the highest industry standards and approved by the BBA (British Board of Agrement) as fit for use in defined roof, wall and floor applications when installed, used and maintained as outlined in the certificate. In addition, the GA4075 comes with a BRE (Building Research Establishment) Green Guide Rating of A, which will help your environmental performance and provide reliable long-term energy savings for your home.
Question:
Does this product still need an air Gap or can I board straight onto it 75mm height in joists or am I going to have to use batons or legs 👍
Answer:
The Celotex GA4075 General Purpose PIR Insulation Board can be installed directly into the joists without the need for an air gap. However, it's important to ensure that the insulation is fitted snugly, with no gaps that could allow heat to escape or cold air to penetrate. If you're using it in an area where there may be risk of condensation, such as a loft or a cold room, you may want to consider ventilation measures.

Question:
Can this product be put on a concrete floor and laminate flooring be placed on it
Answer:
It can be used in flooring applications but you'd still need to level the surface and and have an intermediate layer of timber before the flooring can go on it.
