Questions & Answers


Can this be used as a breathable membrane for timber framed walls




Can this product be applied to wet ply sheets? Will the ply underneath dry out?


This is just an underfelt for use in tile/batten installations under tiles so would not really be suitable. We would advise to let any ply dry out before overlaying with anything.

I needed to alter the roof after my highly skilled builder had done it incorrectly. Good old Bodgit & Scarper. The Tyvek was easy to handle and install and should result in a good repair job from an amateur, at least the Building Inspector approved!!
