What Is T1-11 Siding
Compressed wood siding products are a surprising and unexpected way to house sheds, outdoor buildings, and other outdoor projects. The compressed wooden siding is known as T1-11, T111, T1 11 siding, t1-11 plywood siding, or osb t1-11. The ‘T’ in the name stands for textured, referencing the many channels cut into the siding.
Homebuilders know the textured siding for a “blank slate” since homeowners can transform it into whatever the homeowner wants. Homeowners can change the blank state that the board comes into a wide variety of options, ranging from a clean look to a rustic one. T1-11 siding can be treated with chemicals to fight rot and decay; it is important to note if you have pre-treated siding or if you will need to treat it later.
Although using it for siding applications is common, homeowners can use T1-11 for dog houses, tool sheds, and interior ceilings. The two main types of T1-11 siding are plywood and oriented strand board (OSB).
Plywood has greater durability and holds up better in different weather, but you must weatherize it before use. OSB variety is less expensive due to its low quality.
The siding has the appearance of natural wood grain and is available for a smooth or rough finish. T1-11 siding is cut into panels and consists of thin layers of wood flakes bonded together. The panels make it easy to give the exterior a shiplap construction look. The standard thicknesses of panels are 5/8 and 3/4 inches.
Material Composition of T1-11 Siding
T1-11 siding begins as a blank slate. Grooves are carved into the board to recreate the look of the natural appearance of wood. A few different popular styles are clapboard, shiplap, and board and batten. Other popular textures are sanded, rough sawn, or smooth finish. Some more expensive options for T1-11 siding are cedar, redwood, and Douglas-fir. You can even manipulate the siding to have a rustic finish to give it that new home construction look.
Installation and Maintenance of T1-11 Siding
Proper installation is necessary to prevent deterioration of the wood. This type of siding must be flashed and sealed to protect against weather. The Engineered Wood Association suggests painting all exposed siding edges to prevent damage from construction or bad weather conditions. The edges of the siding are the most absorbent so avoiding unnecessary content is essential.
Each panel of siding is designed to allow overlap by the following board installed. The edges need to be placed over a stud and then nailed into the correct position. Taking the time to measure carefully is imperative; you want to avoid pulling nails and damaging the existing siding.
Like any other siding, you should put sheeting around the area to protect your site and siding materials. Trimming the windows, doors, and corners with wood trim will prevent water from leaking under the top edges of the panels. It will also prevent chipping while installing the rest of the boards. Lastly, you want an excellent stain or paint to finish it up. The paint should match the one that you used to treat the edges. As long as the stain is “all-weather” or a paint and primer combo, then it will be adequate.
Maintenance is required if you want to get the most out of your T1-11 siding. First and foremost, the siding needs treatment to prevent the elements. Because T1-11 siding is plywood or other processed wood, water damage is a likelihood. Staining provides an extra level of defense plus prevents unnecessary damages. Staining the panels make them more durable by adding an extra layer of protection.
If there is any sign of damage to the panels, you can take simple action to prevent further damage. Once the damage is assessed, you can figure out if you need a patch or a new piece of siding. Patches can effectively fix small holes and scrapes without needing to replace the whole panel. One last piece of advice is to keep a small reserve of paint to touch up the siding when necessary. Without regular maintenance, your siding can fall apart and make the material not last as long.
