Strandsarking
What is Strandsarking?
Viking Strandsarking is an H3.1 treated strand board; designed by Juken New Zealand. It is more rigid and spans further than plywood. It reduces the visibility of sheet joins and forgives unevenness in structures, creating a flatter and sharper looking roof.
Strandsarking is an ideal substrate for membrane and asphalt shingle roofs. It is double sided which results in a faster, easier installation and can be laid in any direction resulting in less wastage, and can span up to 900mm.
Viking Strandsarking has two Codemark certificates and two BRANZ Appraisials; one for low sloped roofs - down to 2 degrees, and one for pitched roofs.
The manufacture process involves the soaking of individual woodchip strands in the treatment before they are pressed into Strandsarking sheets. This ensures every sheet is fully treated throughout its entire thickness, as opposed to the conventional methods of treating wood. The treatment used for Strandsarking is solvent-free.
Unlike plywood, the extra length spans an extra truss; resulting in a stronger substrate and less double-nailing at sheet edges
Viking Strandsarking carries a Declare label; meaning this product will not cause harm to the environment or people once installed.
