Celotex TB4040 General Purpose PIR Insulation Board – 2400 X 1200 X 40mm

As a high-quality multi-purpose polyisocyanurate (PIR) insulation board with excellent thermal performance, this Celotex TB4040 insulation is quick and easy to install without any hassle. It’s ideal for use in all sorts of floor, wall and roof applications.

Thanks to the innovative low emissivity foil facing, this insulation board has an outstanding thermal conductivity of 0.022W/mK. As a result, the insulation thickness necessary to meet the target uValue is reduced significantly, which saves you space. The high-performance facer also improves thermal performance in sealed cavity air spaces, boosting uValues even further.
