Wind resistance

It is one of the most important properties of windows and doors. It determines the safety of the entire structure, as it indicates the amount of pressure caused by wind that the window or door structure is able to resist without serious damage. The classification of wind-resistant windows and doors is carried out in accordance with PN-EN 14351-1. The wind load resistance of the window is described by two symbols: the number (1-5) which indicates the pressure of wind applied to the product and the letter (A-C) which indicates the amount of accepted deflection.

Thickness of the glazing unit

A glazing unit is a structure consisting of two, three, or even four panes of glazing separated from each other by a distance frame, sealants and vapour-absorbing gas (argon \ krypton). The thickness of the glazing unit is the overall measurement, from the outside glass surface to the inside glass surface. The average double glazing thickness is about 24 mm while triple-glazed windows are 42 – 48 mm in thickness on average. The number of panes in a glazing unit affects the improvement of the U-value parameter

Water resistance

It is the capacity to avoid water leakages under wind and rain at the same time. Leakage is defined as the appearance of uncontrolled water (other than condensation) on the inner surface of the product. Obviously, the doors and windows with good waterproof performance can effectively prevent water from entering into their internal structure and – as a result – ensure a longer service life. The classification ranges from Class 0 (no test) to Class 7A for windows and Class 3A for doors.

Air permeability

It is the measurement showing how easily air can pass through a window or a door. The European Standard regarding air permeability in windows and doors is EN 12207. It classifies windows or doors according to their capability to prevent air travel through the system. This capability is measured on a scale, from Class 1 (less tightness) to Class 4 (higher tightness). A window or a door system with a higher level of air tightness is more energy-efficient, as less heated air escapes through it.

Depth of the frame

A very important dimension, saying a lot about sliding doors quality and functionality. The depth affects the sound insulation, thermal insulation (U-value) and stiffness of the structure. To put it simply: the bigger the depth, the warmer the sliding doors.


The MB-59 HS system is a perfect choice if you’re looking for energy conservation and environment protection. It is the optimised solution in terms of construction and and profiles and frames dimensions. Lift and slide doors based on the MB-59 HS system can successfully replace traditional balcony windows. They provide enormous constructional possibilities and assure an extraordinary look – both to the interiors and the entire facade.
