Description
Celotex XR4120 is a highly versatile multi-purpose insulation board ideal for various applications including pitched roofs, flat roofs, solid floors and masonry walls and steel framed and timber framed systems. Made of sturdy polyisocyanurate (PIR), it's easy to handle, cut and shape. This convenient high-performance insulation board has excellent thermal performance and an impressive thermal conductivity of 0.022 W/m.K. Knowing that, you won't be surprised to learn that it easily meets the required U-value while also being thinner than most similar products on the market.
But wait - there's more! The low emissivity foil facing improves thermal performance in sealed cavity air spaces and boosts the potential U-value. The XR4120 is produced to the highest manufacturing standards and has a BBA (British Board of Agrement) certificate as fit for use in defined roof, wall and floor applications when installed, used and maintained according to the guidelines. Additionally, the board has a BRE (Building Research Establishment) Green Guide Rating of A, which will assist you in improving your environmental performance. Altogether, this PIR insulation board will provide reliable long-term energy savings for your home.

Questions & Answers
Question:
Can this product be used as a warm deck with 6mm ply fixed from above with slab nails into the joists .???
Answer:
It can be used in a warm roof/deck application, but would suggest a thicker ply (12mm) to overlay. - https://www.insulationsuperstore.co.uk/help-and-advice/project-guides/insulation/insulating-a-flat-roof/
Question:
Is the silver foil a vapour barrier?
Answer:
When used in conjunction with aluminium foil tape, you can create a pseudo air tight seal with your insulation layer, however it is not a complete vapour barrier and so having another vapour control layer in place would be best.
Question:
Is this product approved for use in flat roofs?
Answer:
Yes, Celotex TB400, GA400 and XR400 can be used in a flat roof.
