ArkiBoard Applications
-
Exterior Wall
ArkiShield magnesium cement boards are a fireproof sheathing design for exterior walls. It is made from reinforced Magnesium Oxysulfate cement, grade E mesh fibre, and waterproof polymers. ArkiShield is the leading chloride-free MgO board and has passed all the durability tests of EN 12467(fibre-cement sheathing standard). It is a fireproof and cost-effective sheathing, highly recommend for tile, brick, stone veneer substrate, ETICS underlay, aluminum curtain wall substrate and stucco substrate etc.
-
Interior Wall
ArkiCore magnesium cement board is an ideal interior wall application in high moisture and wet areas like the kitchen and bathroom. ArkiCore is a fire-resistant wallboard that has passed the ASTM E119 and has proven to be a 1-hour fire-rated building material. ArkiCore is also water-resistant and mold-resistant, which is a much better building material than OSB or Gypsum board in wet and high moisture areas. We provide tapered edge and square edge boards for easy installation.
-
Ceiling & Floor Board
ArkiFloor is ideal for use in interior ceilings and sub-floor board applications. Using a 10mm thickness board for the ceiling and a 19mm thickness board for the sub-floor board can give you a 2-hour fire separation. ArkiFloor is good for fire-resistance, water-resistance and sound insulation. We offer tapered edge, square edge, and tongue & groove edge boards for easy installation.
