What materials are your buildings made from?

All of our sheds are made with red wood. Our standard garden sheds are made with 2″ x 1- 1/2″ framework. We then use 12mm kiln-dried tongue and grooved cladding on the outside. Our heavy duty range of sheds comes with thicker framework and thicker cladding. The framework is 2-1/2″ x 1-1/2″. You then have the choice of either the standard 12mm tongue and grooved cladding or the thicker cladding, which is 16mm kiln-dried burleigh shiplap. The roofs on all of our buildings are made with 1/2″ thick sterling board OSB. This is an exterior grade boarding and we  put green mineral felt on top. The floors are made with 1/2″ thick tongue and grooved floor boards.
