In fact, chances are that you’ve already come into contact with T1-11 siding, perhaps without even realizing it. Commonly used for siding, T1-11 has also been a popular material choice for other DIY projects, including tool sheds, dog houses, duck blinds, and interior ceilings.

Trim It. T1-11 sheets come with solid or grooved faces, and many installers under-trim it, leaving joints between boards uncovered and visible. Covering these joints, especially horizontal ones between stories, with 1-by-4-inch trim improves the appearance of the siding by making it look more finished.

T1-11 siding is strong, highly functional and durable – it has a long life as compared to other sidings. However, for many in the building community, it is thought of as cheap and is considered a low-quality material.

T1-11 is a type of siding made of plywood, meaning it’s a material made from thin sheets of wood veneer. These are glued together to give you the look you see. It also means that this is an engineered type of wood.

OSB T1-11 siding has more issues with water because of how it is manufactured. If the OSB T1-11 siding gets wet, it swells and expands, flaking, chipping and eventually will rot. T1-11 will last and stay beautiful if adequately installed, painted or stained, sealed and maintained.

This type of plywood siding is injected with rosins and other chemicals, under pressure, to make it waterproof and protected against termites, rot, and fungal decay. Both Plywood and OSB T1-11 siding should be treated or primed. Sealing T1-11 siding protects it from harsh weather and other elements.

You should put sheeting and house wrap under the T1-11 siding, just like with any other siding. In some areas, you don’t have to use sheeting and house wrap to do the installation, but I would not recommend doing it that way.
