  • Triple glass unit: To achieve better thermal performance (Ug-value of 0.5 or 0.6 W/m2K). 
  • Toughened safety glass: Glass units are constructed with toughened glass
  • Laminated glass: One pane of glass unit can be built with laminated glass for additional security, safety or noise reduction.

Safety & Security Options

  • PAS24 security options for outward opening windows at ground floor
  • Restrictor can be used to limit the amount of opening of the side-hung windows for safety.

Thermal Performance


  • Aluminium windows are usually constructed with thermally-broken frames to achieve higher thermal performance.
  • For existing residential buildings, aluminium windows must have either a Uw-value of 1.4 W/m2K or lower, or a WER Band B to comply with Part L of Building Regulations.
  • For new residential buildings, aluminium windows must have a notional Uw-value of 1.2 W/m2K (with limiting value of  1.6 W/m2K for SAP calculation) to comply with Part L of Building Regulations.
