Thermal Performance

Homeowners can remain warm, dry, and comfortable with our aluminium top swing reversible windows. The thick glazing that comes as standard is capable of reaching U-values as low as 1.7 W/m2K and has a Class 4 (600Pa) air tightness rating.

Choose from 24mm to 28mm glazing to suit your energy efficiency needs. The lightweight aluminium profile allows for an easy to use top swing reversible window even with the heavier and higher performing glazing option. Plus, the aluminium profile itself contains polyamide thermal breaks to ensure maximum energy efficiency.

Get the best of both worlds with durable, slimline aluminium frames and high performance, energy efficient design.
