PROFILE

78 mm profile thickness

The 78 mm HS profile is an excellent choice for modern single-family homes and projects with elevated aesthetic expectations. Its engineered laminated timber core provides high dimensional stability and good resistance to deformation, even with large glazed areas. The system supports triple-glazed units, improving both thermal and acoustic performance.

A 78 mm construction offers a balanced combination of slim profile lines and strong technical performance. It allows an elegant, light visual effect while keeping the sash stable and reliable during everyday use. This option works especially well in terrace and garden openings, where design quality, functionality and user comfort matter equally.

THRESHOLD

67 mm – standard solution

A 67 mm threshold is the classic HS solution, offering strong tightness and high long-term durability. Its stable profile with a thermal break supports effective insulation and protection against water and air infiltration.

The higher threshold also improves structural rigidity in the bottom zone, which is especially important for large and heavy sliding sashes. It is recommended where priority is maximum sealing performance and intensive everyday use.

DETAILS

Details that make a difference in everyday use

Beaded and beadless glazing

The HS system supports two glazing concepts: traditional beaded glazing and a beadless option. This allows you to match not only technical performance but also the final visual character of the construction.

Beaded glazing is often preferred for easy serviceability and proven durability, while beadless glazing emphasizes large, clean glass surfaces and a more minimalist architectural look.

Benefit: Greater design flexibility without compromising tightness and durability.

Timber-aluminium sliding door construction

A timber-aluminium HS sliding door is built around a structural timber core that provides strength, thermal insulation, and a natural interior appearance. Timber offers excellent insulating properties, helping to reduce heat loss and improve indoor comfort. On the exterior side, a durable aluminium cladding protects the structure against moisture, UV radiation, and changing weather conditions, significantly increasing system longevity.

The sliding panels move on precision-engineered tracks using advanced roller mechanisms that ensure smooth and effortless operation, even with large-format glazing. The system also incorporates high-performance insulated glass units and sealing components that provide excellent airtightness, weather resistance, acoustic protection, and overall energy efficiency.
