Quick-to-install Finnish chipboard for walls

KoskiWall is an uncoated chipboard that is suited primarily for various wall structures, such as partition and exterior walls or ceilings, as well as roof support boards. The chipboard can be installed using regular wire nails or screws, making the boards quick and easy to install. The chipboard also responds well to gluing.

Chipboard made from real wood insulates sound

The strength of KoskiWall chipboard is constant in every direction, making it a long-lasting option for walls. Even heavy objects can be easily and firmly secured to the durable and high-quality chipboard walls. The chipboard is made of sawdust, a by-product of the sawmilling industry, which provides the walls with good sound insulation and works excellently, for example, in the internal facing of exterior walls.

In dry spaces, straight-edged, 11-mm-thick standard chipboard is mainly used. If the walls must bear heavy loads, 12-mm-thick straight-edged or tongued-and-grooved chipboard can be used instead. T&G chipboard enables either a butt or chamfer joint on the surface, depending on the side of the panel that is being used.

For walls in more demanding applications and wet spaces (moisture class 2), the P5 grade, which has higher moisture resistance, is recommended. KoskiWall is also available primed on one side.

Clean chipboard won’t damage saw blades

KoskiWall chipboard is made in Järvelä, home to the only chipboard mill in Finland, by professionals who ensure a high-quality end product using clean raw materials. Sawmilling industry wood by-products account for 90% of the content of all the boards. Sand and other heavy impurities are efficiently removed from the raw material before the chipboard is produced, guaranteeing a board that is clean and consistent in quality. The boards can be sawn, drilled and cut using any conventional woodworking tools, as high-quality chipboard is easy to machine and won’t damage saw blades. Blades that are in good condition cut board better and bring savings in equipment maintenance.
