Gemtreeboard is a Magnesium Oxide (MgO) and Magnesium Chloride (MgCl) based construction board that out performs cement based boards and regular gypsum plasterboard. This is due to its fire resistance, excellent acoustics and exterior and interior applications.

Gemtreeboard does not contain any organic solvents, formaldehyde, asbestos, oils or other toxic substances that can have a negative impact on the environment and waterways. As such, saw dust from Gemtreeboard can safely be disposed of in landfills. Off-cuts of Gemtreeboard can be reground and re-used back at the production factory.
