Hello @hellrazor

Insulating a Colorbond or steel shed is a popular topic in the community, and a great way to do it is by building a timber frame inside the existing steel structure. This setup makes the most of the available space while giving you the freedom to choose any interior cladding you like. By spacing the timber frame correctly, you can easily fit standard insulation batts between the studs, helping to keep the shed comfortable year-round.

Here is a link to our best advice: How do you add insulation to a garage or shed?

I suggest having a look at these discussions:

What can you suggest other than batt. Also ImI don’t want to use batts on roof at this point I’m no put in a ceiling nor spray foam

Hi @hellrazor,

I think @bowmatty's method, shown in How to insulate a metal roof ticks your boxes.

He used foilboard attached to the underside of his patio ceiling with Sikaflex 11FC.

This looks like a good option for you.

Let me know what you think.

Good Afternoon @hellrazor

I was looking at your question last night and wa strying to come up with a resonable idea on how to mount anything on the underside of the roof. As there are no supports I am hessitant in offering anything as structually the roof has been built yo only carry the load of the metal sheets themselves.

If you add battons then the spine needs to be re-enforced and so on.

With your walls you still need short studs and maybe batons to be installed, This is definently doable. That way you can install insulation bats and have them stay in place.

Other ways to control the heat are a covering over the roof, maybe 20cm off the roof so the sun dosnt have a chance to heat it like crazy. Same as the outside walls. You could grow vines/trellis next to the walls that would help mitigate the heat and somewhat of the cold.

I’m thinking of using the foil board on the roof . By using spacers and gluing the foil boards to spacer and wedging foil boards between my beams do. Should I seal up all my gaps or should I leave gaps for ventilation to stop mould.

i was also considering putting in rafters to better support foam boards. Same question with the gaps for ventilation . Also do I need to vapour barrier the rafters

Hi @hellrazor,

I'd suggest you closely follow the advice in the Foilboard Shed Installation Guide to ensure the best results.

They recommend sealing the joins and edges with Foilboard 48mm x 66m Green Joining Tape.

Based on the installation guide, I don't think there is any need to add rafters. Just follow the guide closely, and you will have a good, solid install.

Let me know if you have any further questions.
