Q.Which is better, aluminum alloy windows or PVC windows?

A.Both materials have distinct advantages: PVC windows offer excellent thermal insulation and soundproofing due to their low thermal conductivity. They are commonly used in residential buildings and are suitable for complex designs such as curved or custom shapes. Aluminum alloy windows offer superior structural stability and resistance to deformation. They perform exceptionally well in high-rise buildings, large openings, and harsh environments like coastal areas with high humidity or salt spray corrosion. The choice of material depends on project requirements, climate conditions, and personal preference.

Q. Do aluminum alloy windows allow air leakage?

A. High-quality aluminum alloy windows utilize automotive-grade EPDM rubber seals, a material known for its durability and resistance to aging. Combined with a triple-seal structure and optimized isothermal line design, they deliver exceptional airtightness, thermal insulation, and wind pressure resistance, effectively preventing air infiltration.
