Evening All,

I want to insulate my internal garage to try and keep some of the heat in that it gains from the house.

I have sealed any draughts etc and I am going to use some of the aluminium foil stuff on the inside of the door.

What can I use on the ceiling, it is currently plasterboarded and I do have plenty of headroom.

Many thanks,

Steve

Can you get insulation above the ceiling if so i would put as much above as possible.

Just normal insulation do you think?

fit a loft hatch then use rolls of loft insulation
fit 100mm between the joists then 150 ontop across the joist

I think it was B&Q that was /is selling fiber glass cheep £9 a roll

Don't forget the floor! If you can afford to lose 19mm of headroom, then the cheapest and most effective is a layer of dpm followed by 8x2's of T&G moisture resistant flooring chipboard. It will make a BIG difference to working comfort, and you can slide heavy weights around on it easily

You guys don't work hard enough Work harder and generate your own heat!

Kingspans the stuff you need, can be used everywhere, floors , walls and ceilings.

celutex is cheaper than kingspan but is the same , Lidi have thermal boiler suits on for£14 , also carpet the garage floor ! (cheap stuff so you can bin it after the cars built!)

Can I bond Celutex to the roof and is this fire retardant?

Thanks,
Steve

I'm using a high performance composite plasterboard from British Gypsum on my loft conversion at the minute.

It's 12.5mm plasterboard with a layer of closed cell foam insulation bonded to the back of it. You can use it on ceilings / walls / dot and dab, screwed to battens or straight to brick.

Because of the nature of the insulation, it acts as a vapor barrier, reducing condensation too.

I'm not sure that foil on the door will do much I would think you need something with a bit of insulating properties rather than just the heat reflective thing.

i've bonded poly celing tiles to the inside of the door 2 deep were i can, one or 2 have dropped off over the last year (need better glue) but the bare parts are freezing when it's cold out, and boiling when its sunny it's the only 7*7 radiator i've ever seen!!!

I just got a Dickies insulated worksuit.
No problems (I've got a heater but I think I've switched it on twice and (for once!) it's not being tight that stops me....

Did you say its an integral garage? I assume only void above ceiling plasterboards are a few inches where the joists are. i also assume the existing ceiling is some sort of fire barrier too if there are bedrooms above. Does this have a bearing on what type of insulation can be used?

Good quality sealed garage door would be my first starting point. In laws have just had a very smart door fitted that has insulated panels and seals right around. Not cheap though unfortunately. I had a chaper roller shutter door fitted at a previous house (electric type) with brush strips down the sides that was quite good at keeping draughts out.

Buy bubble wrap from ebay and stick loads on your garage door. Makes a huge difference. The garage door is just a huge heat sink (think of it like a radiator - and the hot water is where you are.
