Our double garage has no ceiling, lining or insulation under the dark blue colourbond roof and it gets incredibly hot in summer. I’d like to retro fit some form of insulation and so I’m looking for ideas how I could do this. It’s a steel framed garage with no trusses as such, so nothing to lay a ‘ceiling’ on. Wondering if foilboard could be used and how it could be attached? Or if I could attach something like chicken wire to the steel and use that to hold up some form of foil insulation?
