TimberStrand® LSL Roof Framing

When strength and length really matter

As roof design gets more complex — with longer rafters and multiple peaks — you can be confident that TimberStrand® LSL has the strength and stability to meet your needs and accommodate creativity.

These engineered studs resist warping, twisting and cupping, making them a perfect product for roofs that start out flat and stay that way, for generations.
