IMPORTANT: On 1 September 2017, Celotex took the precautionary measure to temporarily suspend the supply of Celotex FR5000, Celotex CG5000, Celotex CF5000 and Celotex SL5000 while we investigate the results of recent tests (Parts 6 and 7 of British Standard 476). In addition, we have recently identified a compliance issue relating to our calculation and testing of the declared lambda value of products in the 4000 and 5000 ranges and the Crown-Bond and Crown-Fix products within the Crown Flat Roofing range. Due to this issue, the suspension of the 5000 range will continue and now includes the FI5000 and GD5000 products. Materials relating to the 5000 range products are for information only. Please note that all products in the TB4000, GA4000 below 100mm, PL4000 and CW4000 ranges manufactured after 15 December 2017 will be marketed from January as Celotex 3000 with a declared lambda value of 0.023 W/mK.

Celotex launches two new innovative products!

At our headquarters in Hadleigh, Suffolk, our growing team of insulation experts pride themselves in manufacturing innovative solutions for a range of applications in the construction industry. Over the past two years, we have introduced exciting new application solutions including Celotex RS5000, a rainscreen cladding product and more recently, in 2015, Celotex CF5000, our full fill cavity wall solution. We are also leading innovators with our services too, introducing the new and improved U-value Calculator as well as thermal bridging models to the Celotex Members Area.

Today, we announce the release of two new additions to our ‘best-in-class’ performance 0.021 W/mK lambda range.

Both with enhanced thermal performance and installation benefits, saving time and money on-site.
