It has been recognized as a national high-tech enterprise and a “Little Giant” enterprise for specialization, refinement, and innovation.
The Series 65 window is engineered on a 65mm thermally broken profile, purpose-built for architectural applications where rigorous thermal and waterproofing performance are non-negotiable. High-strength thermal break inserts are embedded within the profile, physically separating the interior and exterior aluminium chambers to interrupt heat conduction through the frame. The result is a significantly reduced overall U-value — retaining warmth in winter, blocking heat ingress in summer, and delivering outstanding energy efficiency year-round.
On the waterproofing front, the outward-opening configuration minimizes direct rain pressure on the sash-to-frame interface when closed. Combined with multiple rows of EPDM compression sealing strips and a precision multi-point locking system, the junction between sash and frame forms a robust, layered water barrier. Even under sustained heavy rainfall and lateral wind pressure, the window maintains a hermetic seal — eliminating any risk of infiltration and providing reliable all-weather protection for the interior.
The Series 65 is suited to premium residential, commercial, and public building projects where energy compliance and climate resilience are primary design requirements.
