primed t1-11 8'oc 1/2 inch

T1-11 8" OC Primed refers to a specific type of exterior engineered wood siding panel commonly used on sheds, garages, barns, and residential homes. Here is the breakdown of what each term in the name means: T1-11 (Textured 1-11): The style designation for plywood or OSB-based siding panels that feature vertical grooves (channel cuts) designed to mimic traditional vertical wood plank siding. 8" OC (8 Inches On Center): Indicates the spacing between the vertical grooves. "On Center" means that the distance measured from the center of one groove to the center of the next groove is exactly 8 inches. Primed: The panel comes pre-coated from the factory with a layer of primer paint. This seals the wood fibers, protects the sheet against moisture during construction, and reduces the amount of paint required for the final topcoat. Key Features & Specifications Standard Panel Dimensions: Typically sold in 4 ft × 8 ft, 4 ft × 9 ft, or 4 ft × 10 ft sheets with a nominal thickness of 1/2 in or 5/8 in. Shiplap Edges: The long sides feature overlapping edges (shiplap edges) so adjacent panels interlock seamlessly to prevent water intrusion. Substrates: Most modern T1-11 siding is manufactured using either exterior-grade plywood or SmartSide/engineered wood strand substrate.
