Hi there,
I've just started making an outside store building for some horticultural equipment. The main criteria is it keeps dry (really good insulation is not a concern). The initial construction will be a brick plinth with 4 x 2" studding on. I have just been revisiting some of the posts I've read here before and seen the good advice about having a gap between the vapour barrier and the cladding. The cladding will probably be some sort of feather edge board - maybe Larch if I can find a local supplier.
My question concerns the breathable layer. I will be getting some stuff from Screwfix soon as I have a 10% voucher off for the Trade counters. I wondered if I could be opportunistic and get the breathable membrane from there if they were competitive...

Looking through the products the only two they have for frames are both insulated as well (which I could be tempted to use). However, I was looking at the roofing underlays and wondering what would stop me using those eg the Protect A1 or the VP400.
I'm quite happy to get it from another supplier if the Screwfix stuff isn't suitable - I'm a best just looking for a Tyvek brand layer - or is there a good option from Screwfix?
Thanks, David
