With Celotex GA4000 you are specifying an insulation board that: has a thermal conductivity of 0.022 W/mK; Is suitable for use in a number of applications including roof, wall and floor systems; Comes in thicknesses ranging from 50mm-100mm; Is easy to cut and shape

Oct 09, 2012 · 140mm thick Celotex with a lambda of 0.022 W/mK will give a R value of 6.36m2k/W and will also give a U value of value of 0.16Wm2/K With the exception of sheeps wool celotex is approx twice as efficient as earth, rock or glass Fire risk and acoustics do not come into the equation. Regards oldun Nov 13, 2013 · Using Celotex to fill the cavities is more expensive, but you will only need to use 100mm celotex to achieve a U-value of 0.2 W/m 2 k . The only thing to bear in mind here is that you still need to keep a residual cavity on the outside – but this means the cavity can be marginally thinner. The quick, free and easy way to find out the insulation thickness and the U-value you need for your building project. The U-value Calculator covers all the main ways of building walls, flat roofs, pitched roofs and floors using Kingspan Insulation products. Solid brick walls have a U-value of around 2.1-3W/m² and adding 50mm of expanded poly­styrene (EPS) with take the U-value down to 0. 5W /m²k, which is a sub­stan­tial improve­ment, but 100mm takes it down to just 0. 27W /m 2 k. Celotex Crown-Bond is a high performance flat roofing insulation board featuring innovative composite facers on both sides, a low lambda value of 0.022 W/mK and a compressive strength of up to 150 kPa, providing increased dimensional stability and added robustness. 50mm Celotex GA4050’s low emissivity aluminum foil facing can help achieve lower U-values when installed facing a clear air space within a construction. This is a thermal insulation solution that can help achieve energy use and carbon dioxide emissions targets set by national building regulations.

GA4000 50mm - 100mm XR4000 120mm - 200mm These are all essentially the same product but with varying thicknesses of Insulation Board. Celotex Insulation boards are made from a expanded Polyisocyanurate (PIR) insulation foam with a foil facing to both sides. Lambda Value = 0.022 Thickness = 150mm Sep 30, 2007 · Kingspan and Celotex are essentially the same thing. If you can't get 45mm, then 50mm will be better. You need to provide 135mm. How you fit that between or beneath won't matter, so shop around and get the maximum thickness between (Leave 50mm above airgap) and then you have less reduction inside the hall.
