[Nymrod121]

I need to line the inside of my W.I.P. (Workshop In Progress) with a suitable form of wallboarding that will act as a general purpose fixing surface for sockets etc. as well as having a thermal insulating effect/plain white decorative finish.

Contiboard seems very expensive; plywood would need further effort and materials to present a matt white finish. Any ideas / suggestions would be welcome!

Thanks & best wishes
