When it comes to choosing siding for your home, T1-11 siding (also called t111 siding) has been a popular choice for decades. Known for its natural wood appearance, affordability, and durability, T1-11 siding remains a go-to option for homeowners who want a rustic, classic, and cost-effective exterior.
If you’re considering t1-11 siding for your home, this guide will walk you through everything you need to know — what it is, its benefits, installation, maintenance, and whether it’s the right choice for your next remodeling project.
What Is T1-11 Siding?
T1-11 siding is a type of plywood or oriented strand board (OSB) siding that has grooves cut into its surface to give the appearance of vertical boards. It became popular in the 1960s and 70s as a versatile and economical alternative to traditional solid wood siding.
The “T” in T1-11 refers to the “texture,” and the “11” relates to the specific groove pattern and spacing. T111 siding comes in two main grades:
- Plywood T1-11 siding – Made from layers of thin wood veneer glued together, creating a strong and sturdy panel.
- OSB T1-11 siding – Made from compressed wood strands and adhesives, making it less expensive but still strong and durable.
Both types offer that signature vertical groove design, giving homes a timeless, cabin-like appearance.
