T1-11 siding (also known as “plywood siding” or “rough-sawn plywood”) is a popular, cost-effective choice for sheds, garages, and many residential homes. It’s prized for its rustic, vertical-groove appearance and its ability to function as both sheathing and exterior cladding in one layer. However, proper installation is critical to prevent water damage and ensure longevity.
For a durable, budget-friendly result, pair T1-11 with a well-sealed weather barrier, use galvanized ring-shank nails, and keep the siding at least 6 inches above grade. how to install t1-11 siding on a house
