The new door was lifted sliding aluplast HST 85 mm are unique in the market: they are available in three different versions, depending on the requirements of thermal insulation: the basic version by version of the standard, to the premium version, which meets the highest requirements for passive houses.
ONE SYSTEM - THREE SOLUTIONS
Since the beginning of this year there is some new door system HST 85 mm, which is on the one hand a response to expectations in terms of creating an ever larger window construction, on the other hand, by design changes and, above all, the possibility of wider glazing with a width of 51 mm, It allows to achieve outstanding properties in terms of thermal insulation. A new feature in this segment is the modular nature of the structure, which allows any three product configurations, depending on the expected thermal parameters.
1. HST 85mm version Basic
2. HST 85mm version Standard
3. HST 85mm version Premium
With the freedom to choose different combinations of profiles in lintel part of the door and the shoulder portion, we can choose between three options: Basic, Standard and Premium, which are aimed at different audiences with different requirements regarding the thermal insulation.
Changes in the structure of sections allowed for significant improvement of the thermal transmittance statements profiles, which, depending on the selected option allows you to obtain a weighted average value of heat transfer coefficient Uf = 1.5 W (m2 * K) in the Basic version by Uf = 1.3 W (m2 * K) Standard to Uf = 1.1 W (m2 * K) in the Premium version. Despite its huge size HST doors are so effective barrier against the escape of heat.
The table below presents and the values of heat transfer coefficient Uw for sample doors HST (SCHEME A) with dimensions of 4000 x 2300 mm glass pane twin-chamber heat transfer coefficient for the central part of the glass Ug = 0.5 W (m2 * K) and Ug = 0, 7 W (m2 * K) and the heat transfer coefficient of linear thermal bridge at the junction of the glass frame Ψ = 0.04 W (m2 * K)
The balcony door HST type may be present in at least a few different versions of systems and parts of the wings and unopened. The diversity of structures is one of the undeniable advantages of this solution. Most schemes doors HST are:
- 2-accommodated - with one or two movable wings
- 4-accommodated - with the two middle or all of the moving wings
Specialist window fittings ensure that the wings freely and without any resistance move relative to each other or to the unopened portion of the structure. In this embodiment, the seal is achieved by means of integrated seals, which guarantees a high tightness. Proper sealing the space between the moving door wings HST at a time when they are in the closed position is ensured by a special arrangement of overlapping tabs equipped with a system of rebate gaskets.
The following figure says virtually all of the advantages of the door HST in the development of usable and habitable. Being an alternative to sliding doors, classic doors after the opening of the wings fall deeply in living space, thus determining possible solutions associated with the development of the interior spaces. Despite the larger installation depths of the classic doors, it is the door HST leave more freedom to dispose of the surface.
If we add to this almost unlimited amount of daylight enters the rooms through the huge glass surfaces of the wings and the liquidation of any communication barriers through low-threshold design of the door, then what do you expect more from the balcony door. In one word.
The door was lifted and slide HST 85 mm
The door was raised and sliding-type HST 85 mm may be present in at least a few different versions of systems and parts of the wings and unopened. The diversity of structures is one of the undeniable advantages of this solution.
Most schemes doors HST variants 2-accommodated - with one or both wings moving - or 4-accommodated - with the two middle or all of the moving wings. The solution allows the door HST projects large-size glass facades - the maximum width of a set of doors HST dates back to 6 meters, and the maximum allowable dimensions of the wings is up to 3000x2500 mm.
At the door HST applies special window fittings, which guarantee that the wings freely and without any resistance move relative to each other or to the unopened portion of the structure.
In this embodiment, the seal is achieved by means of integrated seals, which guarantees a high tightness. A suitable sealing a space between the door wing moving in the HST at the time when they are in the closed position is ensured by the special arrangement of the overlapping tap equipped with a system of seals rebate.
A new feature in this segment is the modular nature of the structure, so that variant HST based on the profiles of 85 mm offers three execution options: Basic, Standard and Premium, with different requirements regarding the thermal insulation.
