Overview
Gypsemna Core Board Moisture Resistant Firewall (CB - MRFW - 25mm) is an interior gypsum board consisting of a solid-set, moisture- and fire-resistant Type X gypsum core, enclosed in green-coloured face paper and a strong liner back paper. The board provides superior moisture and fire protection when used in tested wall and ceiling assemblies. The long edges are slightly tapered to allow joints to be reinforced and concealed with joint tape and joint compound. Both the face and back papers are 100% recyclable.
