I'm currently building a toilet/shower timber framed building on my campsite. I'm building the timber frame panels in a barn, so i've done the 4"x2" studs, roof and sole plates, 9mm OSB sheathing, and now i need to attach a DPM.
Does it need to be breathable? Obvoiusly, normal DPM is far cheaper than breathable DPM
Thanks in advance!
