Has anyone else insulated the garge door?

What did you use? Don't want to make it too heavy.

Cheers

Haven't done it myself, but I would think polystyrene stuck on would do the trick... not sure about flame resistance, though

I've tackled the draughts from the top & bottom (mine's an up & over door) with a length of plastic dpc attached to the door top & bottom. That made a big improvement in keeping the heat in. As for insulation, polystyrene sheet is the lightweight answer - but - fire safety would be an issue

The foil backed polystyrene/foam tiled sheets would probably be better protection against fire

I would have thought that using polystyrene tiles would be fine as long as you covered it in something so that welding sparks or grinder sparks couldn't ignite the tiles.

Before I moved house my old garage was one of those steel skinned modular type "Storemore" garages and being made of steel it didn't keep the heat in very well. I lined the skin with polystyrene tiles and then covered these with 18mm tongue and groove chipboard flooring around the walls. I also stuck tiles onto the roof using PU foam as an adhesive and gap filler which helped to keep heat in and prevent condensation. Worked pretty well.

I'd try polystyrene or even thin rockwool with some thin plywood or MDF as a cover. Also, as already mentioned, get rid of any draughts first.

polystyrene is naff! i did it and it made little improvement, the best stuff is roof insulating panels, dead cheap from B&Q, has silver back to reflect heat etc much better than polystyrene, ive put it all over the walls, the door and in the roof, drastic improvement in keeping heat in!

Cheers guys, I'll give it a go!

foam backed plasterboard is designed for insulation and *i believe* is half hour fire resistant by law, but as ever, i may be wrong. That, and it might not fit well
