Excellent thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value.
Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
Celotex boards are light and rigid assisting with ease of transportation, handling and fitting.
Celotex TB4000 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate. Please read the certification at insulation-UK.com/BBA for full details and restrictions.
Celotex TB4000 achieves a BRE Green Guide Rating of A, which can assist in demonstrating environmental performance in your BREEAM assessments . Please visit the Celotex page at GreenBookLive.com for further details.

Full fill cavity wall tongue & groove PIR insulation. Fibre free insulation core with aluminium foil composite to both sides. Engineered jointing system for superior fit. Suitable for full fill cavity wall applications, whilst maintaining a residual 10mm cavity helping resist moisture transfer, aids installation and accommodate mortar squeeze.
2 in 1 insulated dry lining board for fix and dab application. Fibre free rigid polyisocyanurate (PIR) insulation core bonded to 12.5mm tapered edge gypsum plasterboard using proprietary gypsum adhesive. The 2 in 1 board insulates and dry lines walls in one application.
Flat roof insulation Insulation for use with hot applied roofing systems or adhered single ply systems. Fibre free rigid polyisocyanurate (PIR) insulation core faced with coated glass tissue on one side and bitumenised glass tissue with polypropylene fleece on the other.
Recticel Eurothane® Eurodeck is a thermal insulation board for use in warm flat roofs under mechanically fixed single-ply membrane waterproofing systems. Eurothane® Eurodeck is compatible with mechanically fixed single-ply systems, benefiting from high compressive strength and excellent dimensional stability that ensures the flat surface finish required for optimum performance in new build and refurbishment projects. It is faced on both sides with a multi-layer coated aluminum foil.
