Questions & Answers

Question:

can this product be used against the felt between the roof rafters?

Answer:

While this product can be fitted between the rafters, you'd still want to leave a rough 25-50mm gap for ventilation.

Question:

If I use these celotex,-ga-4100 rigid boards would I need to cover them with plywood in order to walk on them or would they take my weight without damage. I would also be looking to install a loft ladder for access.

Answer:

While the boards do have a good compressive strength, it is still advisable to board over them so that weight can be dispersed.

Question:

Can Celotex GA4100 be used between oversite blinding and 100mm of concrete as insulation layer

Answer:

Ideally you'd have a DPM before any form of insulation is laid and then layering of ply over the top of this, we have an excellent guide on how you can incorporate PIR into a floor build up - https://www.insulationsuperstore.co.uk/help-and-advice/project-guides/insulation/insulating-a-floor/

Question:

Hello is this product suitable for underfloor insulation where full access is available - plenty of ventilation is also available. Would 100mm be an optimum thickness for this application ?

Answer:

That would depend if you have been specified a thickness against the depth of the joists, as that would determine how thick the given insulation can be.

Unfortunately we are not able to comment on what would pass/be the optimial thickness, this would be best suited for an Architect or perhaps even Building Control to advise on.

Question:

Can Celotex be used as a cavity fire barrier?

Answer:

No, where cavity fire barriers are required by national building regulations, they should be installed in line with the manufacturer's instructions.

Question:

Can Celotex be exposed to the ground?

Answer:

We advise that when used in ground floors, Celotex must always be above the damp proof membrane (DPM ).

Question:

What is the U Value?

Answer:

Unfortunately, we cannot calculate U Values. For this information, we recommend speaking to your builder or the manufacturer.
