Hi all,
I need to clad the Gable wall and dormers on our new extension. I'm going to use 150mm upvc shiplap, for the Gable wall which is block work with 100mm cavity I'm assuming I should batten the block work with for example tile lats so i can hidden nail the shiplap on, should I put a layer of visqueen dpm over the lats before the shiplap?
The dormers are built from cls and boarded with osb, this is then covered by the roofing felt, should I again batten the osb to fix the shiplap too or can I pin it straight to the osb? I'm assuming no visqueen would be required on the dormers as they are already covered with breathable felt?
Thanks
Chris
