Celotex PL4000 Thermal Insulation Board

NOTE: PL3000 is now manufactured as PL4000.
Celotex PL4000 is a high performance thermal insulation board where PIR insulation is bonded to 12.5mm tapered edge plasterboard. It can be used in new build applications as well as providing the perfect solution for refurbishment projects where little or no insulation exists.
PL4000 is manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has zero ozone depletion potential (zero ODP) and low global warming potential.
- Board size: 1200mm x 2400mm
- Thickness (mm): 25, 40, 45, 50, 55, 60, 65 (excludes 12.5mm tapered edge plasterboard)
- Lambda: 0.023W/mK
With Celotex PL4000 you are specifying an insulation board that:
- Can be easily used to upgrade to current building regulation standards in pitched roof, flat roof and wall applications
- Ideal option for internal solid wall insulation
- Is suitable for both direct bonding ('dot and dab') and mechanically fixed installation techniques
- Offers the installer maximum flexibility and installation speed due to the tapered edge plasterboard
- Offers the user the ability to install both the insulation and plasterboard in one operation, thus reducing installation times
- Future proofs the energy performance of new and existing buildings
