Low-Carbon Impact Material
Regular Board R1 is an interior Type C gypsum board designed for general wall and ceiling applications. It consists of a solid-set Type C gypsum core encased in ivory-coloured face paper and a durable liner back paper, both manufactured from 100% recycled materials. The board features slightly tapered long edges to facilitate smooth joint treatment using tape and jointing compounds. Functional additives such as starch and setting retarders are incorporated to enhance strength, dimensional stability, and consistent setting during manufacturing. The product is inherently non-emitting for VOCs (per LEED) and is pre-checked for LEED v4 and v4.1 – Option 1 (Material Ingredients). Material contents are disclosed down to 1000 ppm in accordance with HPD Open Standard v2.3
