GBOARD CONTRASAG MR
GBOARD CONTRASAG MR
OVERVIEW
Gboard® ContraSag MR is a lightweight and hard-edged, moisture resistant plasterboard with enhanced sag resistant properties. It is mainly used for interior ceiling applications. The core of the board consists of a special combination of non-combustible gypsum, reinforced with fiberglass, silicon oil and special additives. The oil in the core acts as a water repellent rendering it more resistant to moisture. Gboard® ContraSag MR has a green paper face.
By using Gboard® ContraSag MR, material costs are greatly reduced mainly because of the lower number of metal frames required for installation (for the same application area compared with regular types of gypsum boards). To achieve the same structural integrity as other gypsum board suspended ceiling systems, the required thickness of the metal frames is also reduced.
Gboard® ContraSag MR eliminates the cost of moisture resistance treatments.

Advantages
Enhanced with special additives to repel moisture and resist sagging.
Less metal frames used due to the large spacing between the furring channels resulting in cost reductions.

RECOMMENDATION
Do not use veneer products with Gboard® Contrasag MR.
Maximum ceiling span supports 600 mm centers.
Not recommended for exterior applications.
STORAGE & HANDLING
Store Gboard® Contrasag MR in a dry ventilated area indoors. If the boards are stored outside, they need to be fully covered with nylon to avoid water and sunlight exposures.
Avoid direct rain or sunlight.
Avoid cracking or damaging the boards during installation.
