Celotex Insulation

Celotex Insulation

Celotex - a multi purpose insulation board uses include floors, pitched and flat roofs, solid masonry walls, timber framed and steel-framed buildings. Their light weight means minimal additional loading in any structure and are ideal for loft conversions and roof applications

Celotex insulation comes in thicknesses ranging from 12-150mm, but we normally stock these rigid insulation sheets from 20mm up to 100mm. Standard sheet sizes are 1200 mm wide by 2400mm long and are easy to cut and shape. Thicknesses over 30mm thick feature a core foam reinforced with glassfibre.

   ●  20mm Celotex (TB 3020) size 2400mm x 1200mm;

We also carry 45 metre rolls of aluminium backed tape in 50mm, 75mm and 100mm widths for joining boards. Sometimes availability means we may offer Recticel branded insulation boards as an alternative.

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 soemtimes we may substitute Recticel or Kingspan products if we are temporarily unable to source Celotex.
