How can we insulate our Cathedral ceiling?
Filed under Ceiling Insulation, Insulation.
August 13th, 2009
I see from the FAQ on your website (copied below) that it is possible to inject insulation into the cavity between the roof and chapel ceiling. How much is enough space please?
We have a steep concrete tiled roof and cathedral ceilings, uninsulated with plaster below. The space is the thickness of the rafters.
Is it feasible/ appropriate to simply fill this cavity with thermafluff?
Thanks
Carol
Answer on your website that I am seeking further clarification on.
A: A lot of your homes heat (up to 45%) can be lost through an un-insulated ceiling. If your chapel ceiling was not insulated at the time it was built, you have a few choices:
1. It may be possible (if there is enough space between the rafters and the ceiling lining) to inject insulation into the cavity. There are companies in the Yellow Pages specialising in this service.

Hi Carol,
You would need to get an assessment of the feasibility and cost from an installer. Injectable insulation is not covered under the Energywise programme, but there are companies offering this service that should be able to give you an obligation-free quote. ( See the yellow pages -Insulation)
I would suggest asking what warrenty each company provides, anmd if they have any past customers they can put you in contact with to find out how happy they were with the service.
Another question would be how water tight is your roof? A concrete tiled roof may let more moist air in than a corrugated iron roof, and some insulation products deteriorate very quickly if they get damp.
Is there any chance that you would be replacing your roof at some stage? If so, this would be the best time to have some batts or blanket insulation installed.
Please do feel free ti give us a call if you would like to discuss your situation further.
Best wishes,
