Thermal insulation and sound insulation

• Multi cavity structure profiles (bridge cut aluminum) can effectively block the thermal conduction of the profiles themselves, which is the key to improving insulation.
• Multi channel sealing design (such as three seals) can tightly fill the gap between the window sash and the window frame, preventing sound leakage.

Splicing process

45 ° diagonal joint, using corner code injection glue to ensure the overall performance, service life, and safety of doors and windows:

• Ultra high structural strength: The corner code provides mechanical support, and the dedicated structural adhesive achieves molecular level bonding, effectively resisting window frame deformation, settlement, and wind pressure.
• Ultimate sealing performance: The adhesive will completely fill all internal gaps, completely blocking the possibility of air and moisture leaking from corners.
• Durable and long-lasting: The cured colloid has excellent weather resistance, is not easily aged, and avoids abnormal noise and looseness caused by metal thermal expansion, contraction, or vibration.

Window and door corner protectors

• Effectively avoid harm to the human body, especially children, caused by internal fan angles.

Complete set of HOPO hardware accessories

• Reliable Material: Key components are made of high-strength aluminum alloy, zinc alloy, and stainless steel to ensure durability.
• Exquisite craftsmanship: The surface is treated with multiple layers of electroplating, powder coating or anodizing to form a dense protective layer, which is corrosion-resistant and scratch resistant.
• System matching: Emphasize the precise adaptation of the entire solution to specific door and window profile systems, ensuring easy installation, functional implementation, and performance compliance.

Concealed drainage

• Waterproof and leak proof are more reliable: rainwater is effectively discharged outward. Reduce the risk of rainwater 'backflow' during strong wind weather.
• Improve air tightness and sound insulation: reduce air convection channels, enhance the air tightness of windows, help strengthen insulation and isolate external noise.
• More concise and beautiful appearance: The drainage holes are hidden at the bottom or side of the profile, almost imperceptible from the outside.
• Dust and insect proof, easy to maintain: The drainage holes are equipped with invisible drainage covers or windproof covers, which can prevent mosquitoes and large particles of dust from directly entering the profile cavity.
