Enviro Square Meets Group 1-S for Interior Wall Linings

Made of calcium silicate, in the event of a fire, KAPO Board produces an endothermic reaction. While the release of water molecules prevent the spread of fire, it will not produce any toxic, corrosive, or suffocating gas.

KAPO Board is suitable for interior applications and as an external perimeter board. It is high quality, cost effective and easily applied by builders.

KAPO Board will not disintegrate when immersed in water or exposed to freeze-thaw cycles for prolonged periods of time. Numerous tests show no deformation under sustained damp conditions, making KAPO Board perfectly suited for tropical climates and other humid environments. It is commonly used in residential homes as a specialised wall lining such as for the kitchen, laundry, and bathroom.

On top of all this, KAPO Board is also eco-friendly and has high quality sound insulation properties. With KAPO Board, Enviro Square haven’t reinvented the wheel — they've simply introduced a better tyre.


KAPO Board has been tested against New Zealand standards and has been appraised and covered under BEAL’s appraisal, C820. It meets the New Zealand building codes of B1, B2, C3, E2, F2 and G6.

Additionally, KAPO Board has also completed fire testing by BRANZ (FH5551-TT) and is classified Group 1-S. KAPO also completed an acoustic test from Marshall Day.
