What Is 165mm Celotex XR4165?

Minimise heat loss by creating a thermal barrier with 165mm Celotex XR4165; 'XR' meaning 'Extra Resistance', with the XR4000 range featuring sizes thicker than 100mm. 

Featuring foil facings, the 2.4m x 1.2m boards are manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). 

With a low thermal conductivity of just 0.022 W/m.K, 165mm Celotex XR4165 delivers the required U-values with minimal thickness and helps meet the current and future requirements of the Building Regulations. 165mm Celotex XR4165 is suitable for use in a number of applications including roof, wall and floor systems. 


Where Is 165mm Celotex XR4165 Used?

165mm Celotex XR4165 is a highly versatile multi-purpose insulation board ideal for various applications including pitched roofs, solid floors, masonry walls, timber frames and steel frames. 

165mm Celotex XR4165 is produced to the highest manufacturing standards and has a BBA (British Board of Agrement) certificate as fit for use in defined roof, wall and floor applications.

165mm Celotex XR4165 insulation board is an effective thermal insulation solution suitable for use in the following applications:

  • Solid concrete floors
  • Block, and beam floors
  • Suspended timber joist floors
  • Pitched roofs
  • Partition wall and solid masonry wall constructions
  • Timber framed & steel framed systems


Celotex XR4165 PIR Benefits

This convenient high-performance insulation board has excellent thermal performance and an impressive thermal conductivity of 0.022 W/mK.

They are manufactured with eco-friendly concepts in mind, manufactured using a blowing agent with low global warming impact and zero ODP (zero ozone depletion potential). 

Let's take a look at the specs: 

  • Thermal conductivity of 0.022 W/mK - low U-values can be achieved without doubling-up insulation layers
  • Moisture-resistant
  • Low Global Warming Potential (GWP) and Zero Ozone Depleting Potential (ODP)
  • Features low emissivity foil facings giving improved thermal insulation performance within cavity air spaces
  • Easy to cut and shape
