Spruce up your building projects with the OSB3 Board 18mm. Manufactured in the picturesque landscapes of Latvia, this OSB board, also known as sterling board 18mm, is an outstanding choice for use in walls and roofs.
Crafted from robust Spruce and Pine wood species, this product weighs a solid 30.56 kg, making it a robust addition to your construction needs. This 18mm OSB board showcases the superior quality of the OSB3 grade, coupled with the adherence to BS EN300 class standards.
Though this product is best suited for interior applications due to its lack of moisture resistance, its lackarability feature provides a special advantage. The square-edged, unfinished surface allows for an aesthetic appeal that you can finish to your preference, be it staining, painting, or varnishing. It is formaldehyde level E1 (Low), making it a healthier choice for your living or working space.
