Questions & Answers

Question:

Can this be used to insulate a roof space? I'm putting a ceiling into my garage and thought this would be suitable instead of wool insulation.

Answer:

This is purely designed to be used in cavity walls and is not advised to be installed into a roof space, while technically you could use it, wool insulation would work out immensely cheaper overall.
