I'm building a timber frame workshop, starting off with a 4" concrete block layed around the perimeter then a 4"x2" wall.
I'm still to decide whether or not il do a shallow pitch or flat roof.
I have 100mm celotex to put inbetween walls then was planning to put a 9mm osb, tyvek, batten and then clad.
Is this a correct process?? I've been unsure whether celotex was to thick & how I go about air flow in the wall??
I got all the insulation off a building site & a lot of it is paper lined with tiny pin like holes, think it's used for roofing. Is this ok?
