Well one assumes that the fact it has three outside walls might be a factor,
even if insulated. I guess I'm thinking that somehow you need to decide if
the cold is actually coming from the unheated garage and not for some other
reason.

As the nippy evenings and cold nights become more frequent again, I'm
once again thinking about insulating the garage ceiling.

- The garage is roughly 6m by 4m, and our bedroom is above it.

- The bedrooom often feels rather cooler than the main house
(admittedly it's a big room, therefore "airy").

- Yes. I know that bedrooms are supposed to be cooler than the rest of
the house, but I'd rather achieve that by turning down the radiators.

- I keep thinking about sticking (say) 50mm Celotex boards to the
ceiling [of the garage], using mastic of some kind.

- Would it be _worth_ adding more insulation? When built, 25 years ago,
as an extension to our semi, the joists above the garage were packed
with insulation before the plasterboard was fixed. We also have a
roller door fitted, therefore pretty good insulation at that end.

- The whole house is very well insulated in the roof, and also with
cavity wall insulation.

Any comments would be welcome, to help me with this decision!

Cheers
John
