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.
