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 PL4000 manufactured after 15 December 2017 will be marketed from January as Celotex PL3000 with a declared lambda value of 0.023 W/mK.

Ideal where no cavity exists, the Celotex internally insulated solid masonry wall solution is suitable for both direct bonding (‘dot and dab’) and mechanical fixing installation. This application provides a vapour control layer (VCL) when board joints are tapered and jointed, and is particularly suited to refurbishment projects.

Application Benefits:

  • Delivers better U-values and thinner solutions compared to many other insulation materials
  • Offers the installer maximum flexibility and installation speed due to the tapered edge insulated plasterboard
  • Provides reliable long term energy savings for buildings
