Insulated garage door curtains

[8-P]

Our master bedroom sits over our double garage(twin doors). Although I have good quality roller doors our bedroom is always colder than the others.

I’m considering fitting 1 of these on the inside of far door(not used in winter as the car is sat on charge).

Anyone tried one or have views if it might keep some cold out?

Are the garage walls insulated?

Might make more sense to insulate the garage soffit. To stop heat loss through the bedroom floor into the garage.

Garage walls are cavity walls filled(retrospectively insulated). I wondered about using insulated plaster board.

You need to lift the bedroom floor and get some decent insulation underneath. An alternative would be to add a second garage ceiling with insulation between the two.

If your desperate lay some extra thick carpet underlay under carpet. Cheapest solution.

Otherwise insulate garage CEILING with PIR plasterboard, and/or lift bedroom floor and fill with rock wool.

We ordered these:

Mostly because I didn't think to search for garage door specific ones! However, I did mean mine are large so pack the sides and bottom better (where most of the loss is).

Have you got enough insulation in the bedroom floor

I think it is wasted effort if the garage is unheated; you would just be insulating an already cold space.

Improve the floor insulation of the bedroom and/or the roof of the garage?

Exactly. Would seem much easier to insulate the ceiling of the garage than the floor of the bedroom to me.

Feels like a job for the summer. Need to get the car out, remove lighting. I believe it is currently double plasterboard which I don’t fancy removing much, so putting insulated plasterboard on top would seem the best option. Not entirely sure how to attach it given the weight of each board though. A layer of Celotex would be lighter but uglier.

Insulated underlay would be an easy job (if the room doesn't have too much furniture)

Personally I might see it as an opportunity to lift the carpet, put down foil, ply and then underfloor heating topped with laminate/vinyl/carpet.

Whilst not disrupting my living space.

I'm seeing:

Clearing furniture
Stripping carpet and refitting carpet
Having to plane and re-hang bedroom door as increased depth of carpet/underlay means it now rubs on the floor/won't open.

Vs

Sticking insulation to what will be a relatively flat and clear soffit.

Meh why keep things simple? This is PH…

Roller doors are poor insulators and so will be the biggest contributor to the garage being a cold sink for the room above. Sectional doors can be purchased at an appropriate thickness to make then decent insulators. However the replacement cost far exceeds that of insulating the space between the garage ceiling and the bedroom floor. Plus every time the doors are opened, cold air will rush into the garage.

Celotex in battens + more plasterboard on top would be best bet, get more insulation that way then for a cheaper price! or whole hog remove the plasterboard and insulate in between the joists and then another layer of celotex underneath the joists and replasterboard!

Must be tempting to just stick it to the ceiling though, and then paint it if you're worried about aesthetics.

Easier still, paint it on the ground before sticking it to the ceiling. Tape the joins and then paint the tape. The paint must be water based to avoid damaging the Celotex..

Went through this in various stages with varying levels of success/benefit several years ago. Thicker underlay helped a little. Pulling down the original plaster boarded garage ceiling and insulating it properly and reboarding helped noticeably but was a lot of effort. However what finally made all the difference was a need for more space and converting the garage into a heated space. It was a modern estate house so it was useless as a garage anyway.

We have a single sofa garage with ensuite and bedroom above, it flipping cold in the bathroom.

As far as I'm aware the plasterboard in the garage should be fire retardant.

We have it fitted but my plan is to remove it and caulk and edges or places where the floor bits up.to.tje walls, insulated with celotex type stuff, foam any gaps , refit the fire retardant plasterboard.
You can always add another layer of normal plasterboard over the topl after if you wish

I’m guessing the plasterboard that you pulled down went in the bin. Mine is nailed up and I suspect it’ll be a struggle removing it and let alone removing it while keeping it re useable.

Our was roughly plastered by the builder so it was pulled down in bits and ended up in a skip. I recall moaning at time it cost more to get rid of the waste plasterboard than it cost to buy the new stuff.
