Our No Frame technology brings glazing without compromise.
Maximum safety, minimal visual impact, absolute elegance.
What is No Frame
Frameless glazing that elevates architecture
The NOFRAME system is a large-format frameless glazing with minimal metal elements. The glass covers the entire surface, and the profiles are hidden or completely absent. The result is perfect transparency and a maximum supply of natural light.
Frameless design
No visible profiles. Up to 20% more glass area compared to classic windows.
Large formats
Floor-to-ceiling glass panes. We manufacture glazing up to dimensions of 6,000 x 3,210 mm.
Premium insulation
Triple glazing Ug 0.5 or quadruple glazing Uw 0.3 - meets even the passive standard.
Custom production
We manufacture every glass pane precisely according to the project. From a single piece to entire facades.
Extraordinary design
True frameless.
Without compromises.
We are the only manufacturer in the Czech Republic producing frameless windows in combination with Schüco aluminum elements.
The NOFRAME frameless system confirms its design with awards from the most prestigious global juries. For architects, it is a guarantee of a precise, timeless, and proven solution.
No visible profiles. Maximum glass area.
Floor-to-ceiling glass panes.
An architecturally clean solution.
The PD system has been honored with the prestigious world design accolades, the Red Dot Award and the iF Design Award.
Choose frameless glazing
Triple or quadruple glazing?
Both glazing variants meet the highest demands for comfort and design. The difference is primarily in the level of thermal insulation and the energy performance of the building.
Standard
Triple glazing
Best choice
Quadruple glazing
Why is quadruple glazing the best?
Quadruple glazing is an investment
that pays off
For large glazed areas, windows are a key factor in the building's thermal balance. Quadruple glazing with a Uw value of 0.3 W/m²K dramatically reduces heat loss - especially where glass is the dominant part of the facade.
