Garage (with room above) insulation

[Northy]

Hi guys,

Our garage is built into our house with our little girls bedroom above it. Basically we've always thought her room was colder than the other bedrooms so this morning I investigated a bit.

I could only see down the holes where the radiator pipes come up but there seems to be little or no insulation between the garage ceiling and the bedroom floor!

I'm gonna have to fix this but probably not until the weather is a bit better, but what's best to use? I've seen that spray foam stuff used on TV, would that be the best? I'm looking to seal and insulate.

There is also a mini roof bit that sticks out above the front of the garage (~4 foot), I'm guessing this area isn't well insulated either.

Is the easiest thing to take the ceiling down in the garage and work upwards?

Cheers,

G

Why not get some of the space blanket insulation and stick it to the garage roof?

Sounds like a 2 person job, but insulation is generally on offer (2 for 1 the like)

I thought a garage had to meet fire regs/building regs for fumes etc if built as part house, bit bad to have holes from garage to house or is it sealed but with no insulation.

Anyway, thought you bred them hard up north? bit of cold should be fine

I have same problem in my house. The bedroom above the garage is freezing compared to the rest with no insulation between the bedroom floor and cieling. I,ve thought about blowing polystyreen balls into the space from the garage cieling or outside walls or putting a false cieling in the garage with insulation blocks inbetween. Havent costed anything yet though.

If your going to insulate it, might as well seal it as well, fumes from the car can pass up into the bedroom otherwise.

I take it the ceiling in the garage is plastered ?, it should be double tacked for fire and building Regs. I would say it's easier to take this down rather than pull up all the carpet/flooring in your daughters room ?.

Depending on what room is between the floor boards and garage ceiling will dictate what can be fitted in the space. You should be able to 100mm celotex in there or 150mm wool insulation, both will make it warmer.

The ceiling will need to be double tacked again to bring back to Reg's.


I've seen on some of the DIY programs in the US the spray on foam, that look like fun to do . Not sure what that would cost to get someone todo ?.

I think makeing a false ceiling below the original will still give you a cold area between the floor and the new part ?
