Profile thickness

The walls of the window chambers have different thickness, which determines the class of the profile. The thickness of the profiles is defined by the PN-EN 12608: 2004 standard. Profiles can have three classes: A, B and C. This parameter specifies the wall thickness of the profiles. The Class A profiles have outer walls with a thickness of ≥ 2.8 mm. Class B ≥ 2.5 mm. The standard does not define any requirements for class C sections. Class A profiles are the best choice as they provide us with the best window insulation. However, while selecting the so- called “warm” windows, you should also pay attention to such elements as the number of chambers, gaskets, type of the fittings, warm edge spacer, and glazing unit.

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.

Acoustic insulation (Rw)

Acoustic insulation coefficient. It determines the insulation of the sliding doors against noise from the outside. The unit of measurement is decibels (dB). This parameter is influenced by: the thickness of the glazing in the glazing unit, the use of PVB laminated glass or the use of an acoustic foil.

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.

SYNEGO HST

SYNEGO HST is the ideal solution for homeowners seeking a seamless connection between indoor and outdoor living spaces, with impressive glazed surfaces and reliable performance. Thanks to the system’s modern uPVC profiles and advanced lift-and-slide fittings, even large and heavy sashes move smoothly and effortlessly.

SYNEGO HST makes it possible to create panoramic openings up to 5 metres wide using a single sliding sash, or to design patio doors with a total width of up to 10 metres and a height of up to 2.7 metres. The system offers excellent thermal and acoustic insulation, with Uw value reaching up to 0.86 W/m²K and sound reduction of up to 43 dB. This ensures comfort in both hot summers and cold winters, while also significantly reducing outside noise. Optional anti-burglary features provide increased security, and a low threshold guarantees safe, barrier-free access.

An optional Panorama variant is available, which features slimmer profiles and a larger glazed surface for even more daylight. Combined with a wide range of colours and durable HDF-finished profiles, SYNEGO HST provides both design flexibility and long-term performance.
