WINDOR^® window systems are designed to minimize energy losses from residential and working spaces.

The windows comply with contemporary energy efficiency norms and standards employed during construction, therefore they are suitable for installation in low-energy and passive structures.

WINDOR® windows

• ALUMINIUM durability
• PVC thermal brake
• TIMBER the best thermal insulation
• Insulating glazing filled with inert gas
• Low-E glazing coating
• 5 seals EPDM rubber main seal
• Soundproofing up to 46 dB natura profile

Aluminium on the outside surface of the windows is weather resistant, while timber facing living spaces creates a natural and warm ambience. Between the aluminium and the timber, there is a PVC thermal break. Timber is the best thermal insulator, and areas with no draught, moisture and ingress of cold air provide more comfortable and healthier living spaces.

WINDOR^® windows are furnished with Sigenia security fittings. The fittings may comprise an element facilitating ventilation without opening the windows, which is very important in newly built structures due to occurrence of condensate.

Windows executed out of profile:

Uw ≈ 0,8 W/(m²K)
Ug ≈ 0,7 W/(m²K)
Uf ≈ 0,9 W/(m²K)

Uw ≈ 1,28 W/(m²K)
Ug ≈ 0,7 W/(m²K)
Uf ≈ 1,9 W/(m²K)

Uw ≈ 1,54 W/(m²K)
Ug ≈ 1,1 W/(m²K)
Uf ≈ 2,16 W/(m²K)

Ug, Uf and Uw denote thermal conductivity. Lower value indicates lower conductivity, i.e. better insulation. Ug indicates thermal conductivity of glazing, Uf indicates thermal conductivity of profile, while Uw indicates overall thermal conductivity of a window.
