Celotex insulation boards are the ideal product whatever you thermal insulation needs are. Here is a breakdown of the range by function: The unique Celotex online U-value calculator generates a U-value specific to the chosen construction and enables you to input a range of different construction parameters to evaluate their impact on thermal
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
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.
Celotex 100mm GA4100 insulation board comes in the most popular thickness of 100mm, and provides long term energy saving opportunities for domestic, commercial and industrial buildings. Properties Length: 2.4m.

These can be supported with a detailed report. The easiest way of getting a U-value calculation is by using our free online U-value Calculator. For more information, see our articles and how to videos below. 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.
