Celotex GD5000 Plaster Dab Insulated Plasterboards

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 Functions Celotex GD5000 installed on an external wall using plaster dab wall application

Celotex GD5000 is purpose designed for providing thermal insulation and plasterboard as one product.

GD5000 is purpose designed for providing better U Values and thinner solutions in dot and dab solid wall upgrades and other dry-lining applications.

GD5000 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 Description

Celotex GD5000 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.

The product’s kraft paper facings, with their high elasticity and high tear resistance, are ideal for adhesively bonded (dot & dab) installations.

Designed specifically for internal dry-lining systems, GD5000 can be used to upgrade internal solid walls or provide a second layer of insulation including timber frame constructions and between and under pitched and flat roof applications

Product Benefits

Celotex GD5000 is designed to achieve better U Values and thinner solutions in adhesively bonded (dot & dab) applications.

It offers a super low lambda performance of 0.021 W/mK with kraft paper facings, GD5000 is manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has low global warming potential and zero ozone depletion potential.

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

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

Is suitable for achieving thinner solutions in plaster dab bonded dry lining applications

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 

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

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

Reduces thermal bridges formed by mortar joints

Ideal where no cavity exists

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

Particularly suited to refurbishment projects
