Extreme wind resistance and structural safety for modern apartment buildings.
Elegant finishes and superior soundproofing for a quiet, luxury living environment.
Energy-efficient solutions designed to withstand tropical rain and humid coastal air.



Thermal break windows use a PA66 nylon strip to separate the inner and outer aluminium profiles. This significantly reduces heat conduction, saving energy costs by keeping interiors cooler in summer and warmer in winter.
Yes, we support full customization. You can choose from standard colors like Sand Grey and Wood Grain, or any RAL color. Sizes are manufactured according to your specific project requirements.
We use 3C certified tempered safety glass as standard. You can also upgrade to laminated glass for enhanced security or Low-E coating for better UV protection and insulation.
Absolutely. With a wind resistance of ≥ 2500 Pa and a water tightness of 700 Pa, these windows are engineered to withstand the strong winds and heavy rain typical of high-rise and coastal environments.
Yes, our 75 Series comes with an integrated 304 stainless steel mesh screen. It is durable, provides high visibility, and is easily removable for maintenance and cleaning.
