Replace cladding under bay window

Posted by Lisa Averay-Jones, on
Hello, the wooden cladding under my bay window needs replacing as it's rotten. I'm going to use upvc shiplap but should I also use insulation and breathable membrane? I need to make it watertight to the outside too.

Yes if you strip it back use celotex insulation and a breathable membrane that way you will have no problems in the future
