T-111
T-111 siding is a wood based siding product that reached its height of popularity in the 60?s, 70?s and early 80?s, when a more natural, wood-grained look was popular. Its widespread use has dwindled as other siding materials, including steel, aluminum, composite, and vinyl siding have taken over the siding market. It is still produced though but is typically used for shed and barn projects.
Said to be the most environmentally friendly of siding products T-111 siding comes in two types. The first type is known as the T-111 plywood siding and the other is known as Oriented Strand board (OSB). T-111 plywood siding is more expensive than the wafer board sidings or OSB sidings.
So How Is It Made?
Quite simply, T-111 is made from engineered wood (wood products and other materials pressed together), and is a type of plywood siding that comes as T-111 wood siding, or T-111 cedar siding.
So What Is The Problem?
The maintenance of T-111 siding is very important as it has to be protected against water, sunlight, and heat. Painting or sealing is mandatory and must be repeated every few years. T-111 siding is strong and does have a long life as compared to other sidings. However, it is thought of as cheap in the building community, is considered a barn material, and has been shown to have a high moisture absorption rate on the edges after being applied.
