Fiboard M

Product Description

Fiboard M is a non-combustible board based on magnesium oxide. The material is weather- and moisture resistant and therefore suitable for indoor and outdoor applications. When the board comes into contact with moisture, it will regain its original thickness after drying, without any effect on its long-term performance. Fiboard M is easily worked and can be cut, drilled etc. using normal tools.
