OSB

The factories that we represent produce environmentally sound wood-based materials that are CE-certified according to
EN 13986 and produced in compliance with EN 300. OSB/3 is an attractively priced yet strong alternative. This engineered
wood product made from mixed woods lends itself for loadbearing and reinforcing purposes. The sturdy panels are suitable
not only for interiors, but also for use in moist rooms and exterior areas where they will not be exposed to the weather.
OSB/3 excels with excellent dimensional stability and strength. The many advantages of OSB/3 include the fact that, unlike
conventional chipboard, even relatively thin panels are quite strong. Besides reducing the weight of structures, which also
facilitates installation, this saves material.

 

An excellent product designed for normal loads and boasting excellent price/performance, OSB/3 is made using wood from
spruce and Populus species. Before the strands are pressed, a small amount of completely formaldehyde-free resin is added.
As a result, the boards’ formaldehyde emissions are well below even the proposed stricter ceilings. This additionally
enhances their environmental friendliness and lets them be used without any problems for packaging and furniture.

 

Applications

The mixed-wood OSB/3 boards can be very easily worked with commercially available equipment and tools such as hand-held
circular saws. The possibilities for using them are endless: as loadbearing ceiling boards, roof decking, wall cladding, flooring
etc. Nor are they limited to timber construction; they also lend themselves for furniture and packaging.

 

• Reinforcing interior wall cladding, also in moist rooms like bathrooms, laundry rooms and kitchens
• Suitable for exterior use in sheltered places where they are not exposed to the weather
• Loadbearing ceiling boards
• Roof decking (instead of raw timber)
• Wall cladding
• Floors
• Packaging
• Shelves
• Furniture
