Insulated Aluminum Alloy Lower Sash

The Insulated Aluminum Alloy Lower Sash produced by Guanye manufacturer is made of 6063-T5 high-grade aluminum alloy, combined with PA66 nylon insulation strips, forming a stable break-through structure that effectively blocks heat conduction. The overall window heat transfer coefficient is ≤ 2.5W/(㎡·K), significantly reducing the energy consumption of air conditioning and heating. The lower opening angle is 30°–45°, providing gentle ventilation, rainproof and theft-proof functions, and is suitable for high-rise buildings and public spaces to meet safety requirements.

Product advantages are prominent

The multi-sealing design and equal-pressure drainage system of Insulated Aluminum Alloy Lower Sash achieve an airtightness level of 8, water tightness of 6, and wind resistance of 9. It is impermeable during heavy rain and stable in strong winds. Standardly equipped with 3C tempered insulating glass, it provides a sound insulation of 35-40 dB, ensuring a quiet and comfortable environment. The profile thickness is ≥ 1.8mm, with fluorocarbon/powder coating on the surface, which is resistant to weathering and corrosion and does not deform over time. The hardware operates smoothly and supports customization of size, color selection, and batch orders, meeting procurement needs such as price comparison and sample testing.
