K-WALL CLADDING

Grooved Weatherboard • Interior-Exterior

This remarkable K-wall product using 22nd century technology can be set internally or externally.

This remarkable K-Wall product using 22nd century technology can be set internally or externally.

Known as groove board or plank board it comes in size 2.7m x 1.0m x 12mm and can be set horizontally or in a vertical timber look-alike configuration using fast fix ship lap joints.

K-Wall cladding is thicker – 12mm – and stronger than conventional 7.5mm products on the Australian market.

Apart from being a non-combustible building board AS1530.1, it will hold back fire for 90 minutes with just one 10mm K-Wall fire resistant building board . AS1530.4 (C1..C19)-/ 2025  CFC will explode at 800 deg C.

K-Wall is a thicker, more secure 12mm, unlike CFC cement sheets Villa board and Blue board or CSR and James Hardy building board and James Hardy groove board at 7.5mm. K-Wall is less expensive overall when fire protection building is required with less material.

BUSHFIRE BUILDING PRODUCTS

K-Wall is a non-combustible building board while enabling a timber appearance cladding or timber look weather board  particularly applicable in bushfire and similar BAL bushfire areas like BAL 19 BAL 29, BAL 40, and BAL FZ Flame zone building, where no exposed timber facings or timber cladding can be used. FireCrunch K-Wall is a bushfire proof building board that will survive your home in bushfires well over BAL FZ 1200 deg C.

LONG LIFE CLADDING BOARD

Significant additional benefits are a very long life as K-Wall will not rot like timber, is unaffected by weather when sealed.

TERMITE PROTECTION

K-Wall is impervious to termites so protects all expensive timber framing. K-Wall unlike so called water proof plasterboard, will not degrade at all in water or flooding  so provides a unique flood proof building board.

ENVIRONMENTAL

Green environmental building or planet friendly building products are hard to find.

FireCrunch K-Wall environmental cladding is probably the best choice in green option, eco building materials. K-Wall uses kiln temperatures of some 650 deg c half that of cement plaster CFC products at 1300 deg c. On an index of 100 K-Wall FireCrunch is 50% less CO2 in manufacturing however, there is more.

FireCrunch K-Wall is a Magnesia carbonation product which is poured into moulds and during the carbonation period of 14 to 21 days at ambient temperatures draws back 90% of the CO2 produced, so 90% of 50% makes around 5% and an almost carbon neutral Production process.
