UV stable external membranes?

[Alan Ambrose]

Anyone use these and have any recommendations? Our build is slowish and our LPA is properly difficult. Therefore I’m anticipating we’ll have the external roof and wall membranes on show for some time and therefore liable to UV. I can see stuff like Tyvek UV facade, but it still has only a 4-month UV life?
