Product Details

Celotex insulation is a brand name that has largely become the name for all rigid insulation board.  Due to supply shortages with rigid insulation products we now stock Celotex, Kingspan Thermapitch and Recticel Eurothane products depending on price and availability. These are multi purpose insulation boards and typical uses include floors, pitched and flat roofs, solid masonry walls, timber framed and steel-framed buildings. Because of their light weight and excellent thermal performance these sheets incur minimal additional loading in any structure. Therefore they are ideal for loft conversions and roof applications

Celotex insulation comes in thicknesses ranging from 12.5mm -200mm, but the XR4000 insulation sheets range from 110mm up to 200mm.  however, please note these thicker boards are avaialable to special order only. The Celotex XR4000 insulation boards are targeted at ‘cut-to-fit’ applications between rafters or joists and enables users to achieve lower U-values with a single layer of insulation than has previously been possible.

Celotex XR4000 Applications
• Pitched roofs
• Flat roofs
• Solid masonry walls
• Timber framed & steel framed systems
• Floors
We also carry 45 metre rolls of aluminium backed tape in 50mm, 75mm and 100mm widths for joining boards.

For those who like the technical bits Celotex boards feature low emissivity foil facings, GA3000 is manufactured from rigid polyisocyanurate (PIR) uniquely reinforced with glass fibre (except GA3100) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and a low global warming impact.

Rigid insulation boards should be stored dry, flat and clear of the ground care should also be taken not to damage corners or edges. Where possible the boards should be cut with a trimming knife rather than a saw to minimise the creation of dust.  Please note that sometimes we may substitute Recticel or Kingspan products if we are temporarily unable to source Celotex.
