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.

HST 85 mm

The ideal solution for those who want a comfortable connection between the interior and the terrace and a panoramic view achieved with a large glazed area. Thanks to the modular character of the structure, there is a possibility of three arbitrary product configurations, depending on the expected thermal parameters: Basic, Standard and Premium.

HST 85 mm system is available with a low level threshold (50 mm) as standard. It is enough to lift and move the movable sash of the HST window so that both floor levels – external and internal – form one plane. Thanks to this, the space becomes open and elegant. A low level threshold guarantees effective thermal insulation, trouble-free movement for people with disabilities and small children and trouble-free maintenance thanks to removable profiles. It also allows for trouble-free modernisation of lift and slide doors.

On request, there is an additional option available: a 50 mm level threshold with a linear drainage. It is an additional gutter placed on the outer side of the sliding system, that helps to effectively drain even large amounts of rainwater and get rid of accumulated impurities, such as: leaves, sticks or small twigs.

HST 85 mm – benefits

Window frame installation depth and threshold: 197.5 mm
Maximum sash dimensions: 3000 mm x 2700 mm
Depth of the frame: 140 mm
Fittings – lift & slide system up to 180 kg
Special window fittings ensuring that the sashes move freely and without any resistance against each other or against unopened parts of the structure
A special arrangement of overlapping strikers equipped with a system of butt joint gaskets for the adequate tightness of the space between the moving sashes of HST doors
A low level threshold of 50 mm as standard
Three different threshold solutions: Basic (Alu / PVC), Standard (Alu / PVC with thermal break) and Premium (Plastic GFK, filled with foam)
More freedom in disposing of the living space – the doors do not enter deep into the room after opening
The possibility of using energy-saving glazing units with a width of up to 51 mm allows to achieve very high thermal insulation of the structure
HST 85 mm FIXFRAME – a new solution with a very narrow frame in the solid part (FIX) for the greater amount of light coming in
