How it works.
Lift-and-slide (HST) systems, used most often as an exit to a terrace, offer the possibility to create large structures (even 650 cm wide and with a sash weight of up to 250 kg) that move freely. The structures can be made as 2-, 3- (one sash is movable) or 4-quadrant (two sashes are movable). The sash is only 10 cm high and the frame can additionally be built-in, so even a very large window gets a softer look, and its design does not overwhelm the interior. How do these types of systems work?
The moment you turn the handle, the sashes rise above the frame and the fixing locks are released, and only at this moment will it be possible to move them. It is also possible to equip the sash with an electric drive, which will be controlled by remote control. Noteworthy, this type of window, thanks to the fact that it is virtually impossible to move the sash without first using the handle from the inside and lifting it, is characterized by high resistance to burglary, says Krzysztof Kalita, Product Manager at Deceuninck, which offers HST systems.

Tightness and insulation
Lift-and-slide systems offered by manufacturers are characterized by a stable frame and sash structure, which ensures comfortable use due to direct load transfer through appropriately designed reinforcements. In addition, HST systems are distinguished by excellent thermal insulation and tightness even in extreme weather conditions - all thanks to an additional gasket in the sub-glazing space and two rebate gaskets. HST doors also have an effective drainage system, which guarantees high watertightness of the structure.
Wide range of colors
Today, when choosing windows and patio doors, customers pay attention not only to technical parameters, but also to design and finish. Deceuninck brand offers as many as 150 different colored films with different structures (smooth, metallic, wood-textured, pearl), which will allow you to perfectly match the window joinery to the style of the building.

Barrier-free system
When creating the HST system, attention was paid to the height of the threshold, which is extremely important, for example, for people with disabilities. In this case, the height is only 25 mm, and there is also an option for installation on existing screeds. The structure has appropriately designed reinforcements that ensure the stability of the frame and sashes. When purchasing, there is a choice of thresholds in three types: two thermally insulated aluminum thresholds (low and standard) and a basic PVC frame with aluminum covers.
