Superior Thermal Performance

Choose from double glazed units (1.2 W/m² U-value) or triple glazed options (0.7 W/m² U-value) featuring:

  • Toughened safety glass as standard
  • Argon gas filling for enhanced insulation
  • Thermal Super Spacer technology
  • Clear, solar, or privacy glass options
  • Thermally broken aluminium frames to minimise heat loss

Outstanding Energy Efficiency Performance

According to the Energy Saving Trust, improving glazing can reduce household energy bills by up to 10%. Our thermally broken aluminium frames create an insulated barrier that minimises heat transfer and reduces condensation.

The advanced glazing technology, combined with Argon gas filling, delivers exceptional thermal performance. This means less heat loss in winter and better temperature control year-round, making your home more comfortable while reducing heating costs.
