Hi all,
My garage has a pitched roof with box profile plastic coated steel/metal sheets. Its a single pitch from side to side with guttering along the lower edge. It looks like the trusses have been homemade but it all appears solid. There is little additional weight on the trusses except some racks for spare wood etc.
There are currently lots of air spaces allowing air movement underneath the roof.
In winter condensation is a problem with the moisture condensing on the metal roofing and running down the box profile and dripping into the garage.
I am looking at removing the sheeting, putting down marine ply or similar then mounting the current sheets on z-profile 'brackets' and filling the space with some sort of insulation so that the condensation problem is removed.
Sorry if my nomenclature is incorrect!
I'm looking for advice on the type and thickness of board to use across the trusses. What insulation would be most appropriate (kingspan, cavity insulation etc) and what vapour barriers/spacing I need to build into the roof.
Thanks all
Rolf
