The frame features a stepped hidden drainage system, while the sash design incorporates drip lines and independent drainage channels to form a complete equal-pressure drainage structure,
e ectively preventing water penetration. Specially designed glass pads with reinforced nylon material ensure stable load-bearing and prevent sagging of glass panels through diagonal
installation.
Specially designed glass pads improve the overall thermal insulation performance of the window, preventing condensation on the windows during low-temperature and high-humidity weather.
The compression design is in a closed form, enhancing overall insulation performance and resistance to wind pressure.
Utilizes 34mm PA66GF25 thermal break strips, combining indoor and outdoor aluminum alloy with thermal break strips through rolling and compounding, ensuring water and air separation
with equal pressure sealing strips and e ectively separating the outdoor watertight cavity from the indoor airtight cavity.
The middle sealing strip uses co-extruded foam sealant with so and hard components, with a slope design of 13.5°. The combination of ethylene propylene diene monomer (EPDM) and
co-extruded foam sealant forms a three-layer sealing structure that e ectively reduces heat loss caused by air convection.
The corner joints feature pin corner brackets with built-in guide slots. The special adhesive design allows the two-component adhesive to reach the inner corners e ectively, providing high
strength, durability, and precision of 30 threads
