Hello All. New to this forum but have a burning question on insulation. So the house has plasterboarded vaulted ceilings all round. I cannot confirm that there is any insulation at all in the shallow areas between the the ceiling slope and the roof exterior. I have notice though that the bedrooms are freezing.

No to foam, better to strip back, use a insulation batt between the joists,then use a insulated plaster board. Even just overboarding with a insulated plasterboard you should see a difference,but above method is better.

Spray foam, no. Cutting and fitting 3inch celotex/kingspan between the vaulted part and between the ceiling joists, yes.

Typically I will always use celotex in every in job where insulation is required but when it comes to complex roofs with lots of different angles it can be time consuming to get a perfect fit. So I'm always looking at ways to do a better job when I can across icynene on a trade show.

I would urge caution with this product as it contains Isocyanates. The contactors applying the stuff use forced air breathing equipment as it is so toxic.
