High-quality Aluminium Window Profiles Using Pure Aluminium Ingots

Structural Integrity

Engineered with thickened wall thickness of 1.8mm, this lift-and-slide door profile withstands wind loads up to 2400Pa. The reinforced sash design distributes weight evenly across stainless steel rollers, enabling smooth operation for large panel sizes up to 3m² per unit.

Energy Efficiency

A triple sealing system with foam-filled chambers achieves sound insulation of 38dB and thermal insulation U-value of 1.4 W/m²K. The low-emissivity glass compatibility further reduces heat loss, meeting passive house standards in temperate climates.

User Experience

The ergonomic handle design requires minimal operating force, while the automatic drop seal engages when closed. Maintenance is simplified through accessible track cleaning ports and adjustable roller mechanisms for long-term alignment stability.
