Timber can be used for many exterior projects such as, timber frames, gazebos, decking, cladding, outdoor furniture and much more. There are a variety of timbers that can withstand unpredictable weather conditions and with the correct treatment the timber will hold its natural colour throughout. This means there are also many timbers that are not suited for external use and will rot when the woods moisture content reaches 20 percent. This could also result in mould and fungi growth!
