T-STRAND Pro OSB RV flooring

For construction of RVs, travel trailers, and campervans, balance is critical. Whether OEM-built or enthusiast converted, weight and strength are equally important in order to balance durability with drivability.

Our Tolko T-STRAND Pro OSB RV Flooring provides a durable, impact-resistant surface that not only protects, but is lightweight enough to help cut-down on fuel consumption. This makes it an ideal choice for subflooring in motor homes.


Build better with T-STRAND

Made with aspen fibre, T-STRAND offers exceptional fastening and workability, with split-resistant panel edges. Manufactured with moisture-resistant resins, our OSB RV flooring features our Blue Edge Seal, which further protects against swelling. For quick installation and fewer seams, we offer special sizing, including convenient, oversized panels.

Trusted products

With T-STRAND Pro OSB RV Flooring, you can feel confident with the finished product, knowing our panels are APA-quality-assured and manufactured to exceed PS2 and the minimum 19/32 CAT STR 1 rating. And, to make sure these quality panels arrive safely at your doorstep, every order is shipped inside a woven-poly bag for added protection against the elements.

To keep the air quality in your RV clean, our T-STRAND contains no added urea-formaldehyde resin (NAUF) and is exempt from U.S. HUD Manufactured Housing Standard and CARB regulations.

Panel matching made easy

Laminating structural insulated panels (SIPs) can feel like you are putting together a puzzle, with OSB boards that never quite seem to fit. To help you get the quality you want, and avoid the stress of finding just the right piece for your project, we offer our dimensionally stable and consistently straight OSB SIP Facers.


Tested to the highest standards

Tested to APA’s standards PS2 and PR-N614, these unsanded panels are compatible for laminating with insulating polyurethane (PUR), polyisocyanurate (PIR), and polystyrene (EPS) foam cores.


Build better with T-STRAND

Our SIP Facers offer increased moisture resistance with our Blue Edge Seal, which protects against swelling. To ensure our product arrives at your door in the same condition it left our mill, we ship our SIP Facers in a woven-poly bag for extra protection against the elements.
