Acoustic performance up to Rw 42dB with laminated double glazing. Perfect for high-rise and commercial facades.
Curtain Walls
Structural and semi-structural glazing systems for commercial facades with prefabricated unitized panels enabling rapid installation. Silicone-sealed glazing joints withstand thermal movement and seismic deflection. Wind load resistance tested to 4.5kPa with optional 5.5kPa for cyclone-prone regions.
Entry Doors
Premium aluminum entry doors with 5-point multi-lock system, reinforced hinge side, and anti-drill cylinder protection. Polyamide thermal break prevents condensation in cold climates. Available in powder-coated (200+ RAL colours), anodized, or woodgrain foil finishes. Security tested to AS2047.
