Modern and energy-saving, hoisted-sliding balcony door THERMO HS ALU
are a perfect solution in the scope of balcony and terrace door. Thanks
to the possibility applying glazing much larger than in the case of
turn balcony door, rooms are optically enlarged and filled with natural
light. The sense of open space is additionally enhanced thanks to the
floor threshold, which makes and almost flat passageway from inside out,
and creates an area devoid of architectural barriers. Depending on the
customer’s requirements and architectural design, it is possible to
install four door elements with movable or fixed leaves.
The most important parameter which defines the energy-saving level of
the door is the overall heat transfer coefficient for the entire hoisted
sliding door (Uw). The lower this coefficient is, the less heat the
given house loses, which also means lower heating costs. Properly
selected frame thickness and energy-saving, insulated triple glazing
package allow to obtain outstanding heat transfer coefficient for the
entire door, coming to Uw=1,00 W/m2K.
The wood the hoisted-sliding door are made of is subject to very
thorough selection, only timber with dense rings is selected.
In the case of the THERMO HS ALU line, the frame -
together with the aluminium - is 206mm thick, whereas the leaf is 91,5mm
thick. We make door using mainly pine, meranti or oak wood.
The hoisted-sliding balcony door THERMO HS ALU have
additional protection of the wooden frame against adverse weather
conditions in the form of aluminium cover plate, fitted to the frame, on
the facade side.
The key advantage of the hoisted-sliding balcony door is their
functionality. The applied structural solutions allow to obtain very
large glazing, which exceptionally emphasizes architectural features.
When closed, the door look aesthetically and let in a lot of light, open
door take little inside space, as the leaf slides in parallel to the
other one. This system guarantees confortable and quiet use, while
requiring minimum force; the movable leaf can be put in any position and
interlocked in a secure manner.
Balcony door THERMO HS ALU are a product which meets a series of requirements, which no other terrace door systems have met so far.
The THERMO HS door significantly increase the dwelling
comfort and convenience – large glazing, minimum amount of space
required to open the door quietly and remotely, as well as possibility
of adapting the threshold to the needs of the disabled make them
innovative, modern and highly functional alternative for the traditional
balcony-terrace door.

The low emission glass decreases the temperature of the inside pane, which makes the room warm even at low outdoor temperatures.
The heat transfer coefficient for such glazing unit is Us=0,6 W/m2K
Antisol - decrease effects of sunrays, while providing splendid thermal insulation. They are recommended to be installed on southern and south-western facades of buildings.
The anti-burglar panes are used when special protection of life, health or property is required. The external pane consists of two glued panels, between which several layers of antiburglar foil are placed.
They prevent injuries in the case of breaking the pane. They are characterized by increased impact strength. They are recommended to be used in sports halls, offices, commercial facilities, public buildings.

Sound insulation is ability to muffle noise. Increased sound absorbing power means muffling of noise by at least 38 dB. Windows equipped with glazing units with increased sound insulation are recommended for buildings situated near roads, airports, railway tracks, etc.
Reflexive (mirror) panes decrease effects of sunrays, and the mirroring effect protects privacy of the inhabitants.
