The Kerabit OSB roof board is a durable building board made from cross-glued strands of wood. As no formaldehyde is used in its production, this product is environmentally friendly. The size of the boards is 2.7 x 1.2 m.
During the manufacturing process the glue forms a surface that prevents dirt and moisture from permeating the boards.
The 18 mm thick boards are suitable for k600 and k900 truss spacings. The boards are fixed onto the trusses with at least 50 mm nails or screws with approximately 15 cm spacing.
The 15 mm thick OSB roof boards are suitable for k600 truss spacing.
Both boards are tongued and grooved all around.
