    Hi,

    I’m looking to ‘convert’ my garage into a games room and gym.

    I’m not sure how much I’ll be using it so looking to do it as cheap as possible and bit by bit.

    my question is what, from an insulation perspective I should do first? I’ve done nothing yet but paint the brick walls.

    I’m considering thermal foil on the garage door, but also wondering if I could do the same up in the rafters - staple it on? Seems cheap and easy, but do I need to worry about ventilation? There are a couple of boards in the loft area, but that’s it.

    Thanks for your help!!

    What type of construction is the roof? Door?
    What’s the heat source?

    Hi, thanks for your help.

    It’s an up and over, steel panel, canopy framed door (basic - it’s what was installed by the house builder). I’ll probably heat with a oil radiator, but likely only when in use.

    I’ve taken some pictures of the roof area. I think it’s common trusses.

    You need to close the roof space by adding plasterboard ceiling , rock wool above.
    Open roof like that will swallow any heating . Doors are difficult to seal effectively. Is there another door?

    Yes, there are two of those doors, and a uPVC single door.

    Plasterboard ceiling makes sense; sounds thorough. Is there any other option, or is that it really for this tier of construction??

    Doors or ceiling first?! I’m currently thinking the thermal foil would be quickest and easiest to install for the doors.
