Beneath its elegant surface lies robust performance. The system is fully thermally broken and achieves Uw values as low as 1.3 W/m²K with up to 28mm glass thickness. Sound insulation reaches up to 36 dB, while the system meets Class 9A water tightness, Class 4 air tightness, and 2400Pa wind resistance. Security is assured through PAS24 certification. Options for solar control, privacy, low-iron and acoustic glass are available, along with designer hardware and anodised or RAL finishes—ensuring tailored performance and visual integration.
Reliable Performance, Built In
Fully thermally broken, the system achieves Uw values as low as 1.3 W/m²K and sound insulation up to 36 dB. Designed for resilience, it’s certified to PAS24 and tested to Class 9A water tightness, Class 4 air tightness, and 2400Pa wind resistance.
Lightweight Strength
The slim aluminium profiles are engineered for durability without visual bulk. With glass thicknesses up to 28mm and sash weights of up to 40kg for windows and 60kg for doors, it delivers effortless operation and long-term reliability.
