Celotex Products With a 90 year history, Celotex offers a range of high quality insulation products, including: The Celotex GA4000 Insulation Board, a multipurpose PIR board suitable for insulating rooves, walls and floors. It comes in a variety of thicknesses from 50-100mm and achieves an A+ rating when compared to the BRE Green Guide.

This level of efficiency means that the thickness of insulation needed to hit the required U-value is reduced, thereby optimising space in construction design. We stock the Celotex GA4000, XR4000, and PL4000 thermal laminate as well as a selection of their high-performance PIR insulation board.

You will not achieve the correct "U Value" which is the thermal resistance. In a nutshell your roof could end up with condensation (interstitial). Ideally if using Celotex you need a minimum of 120mm. Jun 21, 2016 · Lower U-Value is better. The Kingspan blog suggests that you put a DPC behind the battens. Unfortunately it is not a build up I am that familiar with, and condensation is quite a specialist area, but it seems that you have your exterior wall, a strip of DPC behind each 25x47mm batten then 82.5mm Kingspan K18 or the equivalent Celotex product. 100 mm of insulating wool (of any type, they have same R values )compressed to 90 mm will give you the same insulation value as 50 mm of Celotex, but have the following advantages. a) It will be around 40%-50% cheaper ( for roll type, not batts ) b) It will give you some sound insulation We also carry 45 metre rolls of aluminium backed tape in 50mm, 75mm and 100mm widths for joining boards.

The Kingspan provides better insulation based on these scientific A U-value is a sum of the thermal resistances of the layers that make up an entire building element – for example, a roof, wall or floor. It also includes adjustments for any fixings or air gaps. A U-value value shows, in units of W/m²·K, the ability of an element to transmit heat from a warm space to a cold space in a building, and vice versa. Advantages of 100mm Celotex FR5000: Has a lower thermal conductivity value (0.021W/mK) compared with other typical PIR insulation boards providing enhanced thermal performance and better U-values Achieves an A+ rating when compared to the BRE Green Guide 2008
