What is NOFRAME
Frameless windows NF3, NF4.

Frameless. Just glass.
Concealed profiles and clean lines. Glass covers 100% of the visible surface, opening up completely unobstructed views.
Large formats
Floor-to-ceiling glazing. We manufacture large-format glass up to dimensions of 6,000 × 3,210 mm.
Premium insulation
NF3 with triple glazing and NF4 with quadruple glazing. High thermal comfort even with large glazed areas.

Standard
Triple glazing
Best choice
Quadruple glazing
Why is quadruple glazing the best?
Quadruple Glazing as an Investment
For large glazed areas, windows are a key factor in the building's thermal balance. Quadruple glazing reduces heat loss - especially where glass is the dominant part of the facade.
