Hello,
I'm soon going to be building a 4m X 4m Vudas Devon "log cabin". I've put down a concrete base and the shed comes with pressure treated bearers for the base (on to which the floorboards will be fitted). The instructions have the bearers installed in parallel, presumably so that air can circulate underneath the shed. If I install the bearers so that there is no air gap (basically, lay 4 bearers in a square, the rest in parallel) on top of a waterproof membrane, I can then add insulation under the floorboards. My question is will any benefit gained by having the insulation be lost by lack of air circulation.
Many thanks,
Glenn
