SIG - Moisture Fire Resistant Gypsum Boards

SIG MRFR is produced from high purity natural gypsum core being sheeted in closely adhering paper liners. SIG MRFR is produced in compliance to ASTM C1396 and EN 520 standards. SIG MRFR is tested and certified by leading third party laboratories. They are produced in wide variety of length, width, thickness and edge types to cover the entire spectrum of the requirement.

SIG MRFR combines the properties of SIG FR and SIG MR Plasterboard and thus can be used in wide range of applications where both of the properties are desired.

SIG MRFR is laminated with green paper on face and grey paper on the back. It is high performance plasterboard designed to perform in the interiors with high humidity and high requirements for fire resistance. It is designed for direct attachment by screws, nails or adhesive to wood or metal framing and even existing surfaces.
