Wooden-aluminium lift-and-slide door HST

The internal surfaces of the profiles can be finished in a wide range of colours, including both transparent varnishes that highlight the wood grain and opaque coatings in uniform colours. The coatings are UV and abrasion-resistant, ensuring durability and colour stability in everyday use. The colour is selected individually for each type of wood in order to preserve its aesthetics and visual consistency in the interior.

The aluminium cover is available in a wide range of RAL colours and anodised options. The coating is resistant to UV, moisture and temperature fluctuations, eliminating the need for external maintenance.

The window structure is made of laminated wood, providing dimensional stability and resistance to deformation. The raw material is dried to the appropriate moisture content, ensuring its performance many years. The wood is selected for quality and density to minimise the risk of warping or twisting of the profiles.

Aluminium cladding is available in three stylistic variants, which differ in profile geometry and the way they shape the external appearance of the window. SOFT is a rounded line with a soft profile that visually warms up the façade. MODERN features a simpler, more expressive form that suits modern, geometric buildings. PURE is a minimalist, flat cladding that creates a uniform frame effect, ideal for architecture with very simple details.

The lift and slide doors use double or triple chamber glazing units, enabling high thermal and acoustic insulation parameters to be achieved even with large glazing areas. The glass is ground around the perimeter, improving edge resistance to stress during door operation, while the TGI spacer reduces energy loss at the glass edge. Depending on your needs, laminated, acoustic and solar control options are available, allowing you to tailor the glazing unit's parameters to your building's requirements.

The profiles are available in three thicknesses: 68, 78 and 92 mm, which allows the structure to be adapted to thermal requirements and window sizes. Thinner profiles are suitable for standard applications, while thicker variants allow for the installation of larger glazing units and improve the rigidity of large glazed surfaces.

The bottom threshold is made using 10-chamber technology, which improves the thermal insulation and stability of the entire structure. The running rail is positioned 5 mm above the threshold, facilitating water drainage and ensuring a convenient passage between the interior and the terrace. The threshold design works with the lift-and-slide mechanism, stabilising the sash at every stage of movement.

The TGI spacer separates individual panes in the glazing unit and maintains a constant distance between them, which has a significant impact on the insulation properties of the window. It is made of a material with low thermal conductivity, thus reducing energy loss at the edges of the pane and reduces the risk of water vapour condensation.

The door uses an EPDM seal system, which improves the tightness of the entire structure. The material remains flexible across a wide temperature range and stabilises the pressure of the sash during lifting and sliding. The system reduces the penetration of cold air, moisture and noise.

The door is equipped with a system bolt that works with PORTAL HS lift and slide fittings. This element is responsible for stable locking of the sash along its entire height and maintains even seal pressure. The mechanism operates smoothly even with heavy sashes.
