UNI EN 14351-1
Gm System compliance

Even though the Gm System was conceived as a “second closure” and therefore doesn’t need to be certified like traditional windows and doors, GM Morando wanted to testify as to the quality of its product by obtaining compliance to regulation UNI EN 14351-1*.

This legislation regulates the performance of windows and doors for the following characteristics:

Air Permeability, or how many air drafts there are in the window frame at high/low pressures. The Gm System has the highest classification or the least permeability.

Water resistance or at what atmospheric pressure does it begin to filter water. The Gm System is compliant with regulations.

Wind resistance: the Gm System complies with standard regulations. During the test, the Gm System resisted wind speeds and pressures of over 100 km per hour over the entire surface area.

Safety impact test: in the test weights of 50 kg were dropped onto the weakest points of the frame. The Gm system conformed to regulations and obtained the highest classification.

The Gm System can be supplied with one of three choices of floor rail guides.

Both the recessed and external rail with a stopper, guarantee air permeability, resistance to the elements and safety according to regulation UNI EN 14351-1*. Instead, the option without the floor guide rail conforms to regulations for safety and wind resistance. In this case a seal brush is present in the lower part.

Quality brands
Certification, Oxidation and Painting

The Gm System profile uses the following quality brands for oxidation and painting: QUALIDECO, QUALITAL, QUALICOAT, QUALANOD.

Anodising the profiles, pins and screws in INOX stainless steel at 20 microns enables the Gm System to be installed also in coastal areas where there is a high content of salt in the air.

Certification
Glass regulations

We use tempered glass to comply with regulations.

The tempered glass is obtained by hardening during heat treatment, a process which makes it mechanically more resistant (for example tempered glass is used in the automobile industry for car side windows).
