Our timber is VAC pressure treated and kiln dried to low moisture levels. We install a membrane barrier and also use 18mm WPB (Water and Boil Proof) external grade ply on the flooring panels in comparison to the OSB sheeting used by most timber frame manufacturers.

Exposure to rain during erection will not have any impact on the structure. The timber will dry out quickly once the roof has been felted and battened with no adverse effects.
