Celotex GS5000 Insulated Plasterboards

Currently not available. To be superseded by Celotex GD5000

Specialist Celotex Product, available in most thickness’s, but in reasonably large pack quantities.
Generally, we are unable to split the packs / sell boards individually. Some depots may make exceptions if pack quantity levels are exceeded. Short lead-times apply to GD5025, GD5040, GD5050 and GD5060 boards

Product Applications Celotex GS5000 application installed on battens afixed to a solid wall

Celotex GS5000 is purpose designed for providing thermal insulation and plasterboard as one product.

GS5000 is purpose designed for providing better U Values and thinner solutions in mechanically fixed solid wall upgrades and other dry-lining applications.

GS5000 can be specified for use in a variety of applications including:

The "underneath" layer of insulation in 'between and under' rafter and joist applications

Solid masonry walls

Timber frame lining applications

Product Characteristics

Celotex GS5000 is a plasterboard thermal laminate comprising of premium PIR insulation bonded to 9.5mm tapered edge plasterboard, with a thermal conductivity of 0.021 W/mK.

Designed specifically for mechanically fixed dry-lining, Celotex GS5000 can be used in internal solid wall upgrades or provide a second layer of insulation in timber frame constructions and as pitched and flat roof insulation

Product Advantages

Celotex GS5000 is designed to achieve better U Values and thinner solutions in mechanically applications.

It offers a super low lambda performance of 0.021 W/mK with kraft paper facings, GS5000 is manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has low global warming potential and zero ozone depletion potential.

Allows common target U Values to be met with the thinnest possible solution, allowing 50% less insulation than some other certified systems helping optimise internal living space

Provides the highest performing PIR plasterboard thermal laminate, offering up to 15% thinner solutions than typical PIR

Can achieve up to 30% better U Values using comparable build ups, assisting in delivering enhanced carbon savings

Is suitable for dry lining applications requiring mechanically fixed installation techniques

Available and accredited for a wide range of installation techniques providing speed and flexibility to the installer, offering time and cost savings

Offers the installer maximum flexibility and installation speed due to the tapered edge plasterboard

Can be used in pitched roof, flat roof and wall applications

Reduces thermal bridges formed by mortar joints

Ideal where no cavity exists

Provides reliable long-term energy savings for buildings Is suitable for both new build and refurbishment projects

Can be easily used to upgrade to current building regulation standards

Provides a vapour control layer (VCL) when board joints are taped and jointed

Particularly suited to refurbishment projects
