Revealing our latest breakthrough

At Celotex, we've come up trumps again with our latest technological breakthrough enabling you to achieve better U-values from our new Celotex FR5000.

Delivering an exceptional lambda value of 0.021 W/mK, Celotex'  premium performance insulation is the only PIR to achieve the landmark lambda value, an 'A+' rating when compared to the BRE Green Guide 2008, British Board of Agrément validation and Class O fire performance - showing Celotex' dedication to technical progression within its market leading range of PIR insulation. And now, featuring Celotex IQ, providing super low emissivity values, Celotex FR5000 delivers some of the highest performing rigid board insulation solutions

Specially developed by Celotex' team of experienced scientists and technicians, the foil faced polyisocyanurate (PIR) FR5000 board reinforces the company's position as the leading product developer within the PIR sector. Over 100% more thermally efficient than many mineral fibre products and up to 10% better than typical PIR, FR5000 has been developed specifically for use in pitched roofs, floors and walls to meet the increasing demands of specifiers who require unparalleled product performance.

FR5000 is available in a range of thicknesses from 25-150mm for use in pitched roof, wall and floor applications. Celotex CG5000 also delivers these same pioneering insulation properties and provides our premium solution for partial-fill cavity walls.

Or why not register for the latest Celotex CPD?  "Using Celotex To Meet Part L 2010" provides all you need to know about the latest changes to the Building Regulations and has now been updated with Celotex FR5000 to offer the best U-values to meet Part L with even thinner solutions.

When it comes to meeting the demanding CO2 emission targets, new Celotex FR5000 wins hands down!
