OSB/3 Structural Board — Strand Board For All-Season Construction

Product Introduction

Oriented Strand Board, known in the trade simply as OSB, is engineered from precision-cut wood strands laid in oriented layers and bonded under heat and pressure. Our OSB/3 grade is the workhorse of the range: load-bearing certified to EN 300, and suitable for both dry and humid service conditions as defined by EN 13986.

Large strand flakes on the outer layers run lengthwise for strength along the panel; the cross-oriented core layers lock the board against swelling and twist. The panel you receive is uniform, dense, and ready for structural duty.

Standard Data

Why Builders Keep Specifying OSB/3

Consistent mechanical values panel to panel - no hidden voids, no weak spots.

Holds screws and nails tightly along edges, a real advantage for fixings close to panel boundaries.

Large sheet coverage means quicker closing-in on site and fewer joints to tape or seal.
