Profile Thickness: Follow National Standards, Choose as Needed
According to GB/T 8478-2020, the main profile thickness for exterior windows should be at least 1.4mm, and for exterior doors, at least 2.0mm. Thin profiles, around 1.0 to 1.2mm, especially from smaller factories, tend to bend or fall off easily. But thicker isn’t always better. For tall buildings or coastal areas, 1.8mm is better. For regular exterior windows, 1.4 to 1.6mm usually works well. Indoor doors and fixed windows can be made with 1.4mm profiles.
Glass Configuration: Based on Sound & Heat Insulation Needs
● Sound insulation: Use double or triple-glazed windows with at least 12mm of insulating space for houses facing the street. For places with higher noise concerns, combine insulating glass with laminated glass for better soundproofing.
● Heat insulation: Choose low-emissivity (Low-E) coated glass to cut down energy use by 20-30%. In colder areas, filling the space between panes with inert gas can improve insulation. Also, make sure external glass is safe—use tempered glass for large windows or French doors.
Sealing Performance: Seals + Multi-channel Sealing
● Seals: EPDM is the best choice since it’s weather-resistant and lasts 10 years or more. PVC and regular rubber tend to wear out faster, usually around 3 to 5 years.
● Structure: It's best to go with at least 3 sealing channels—like between the profile and glass, the frame and sash, and the frame and wall. Higher-end options might also include dust strips for extra protection.
Hardware Accessories: Focus on Brand & Material
● Brands: Focus on German brands like HOPO and SIEGENIA—they've got over 100,000 openings and last around 15 to 20 years. Cheaper hardware tends to rust or break pretty easily.
● Materials: Use 304 stainless steel for the parts that bear weight. Handles should be electroplated or powder-coated. If your budget allows, you can add optional buffer functions.
Surface Treatment: Choose Process by Scenario
● Powder coating is a popular choice that's affordable, durable against weather, and works well for most homes.
● Fluorocarbon coating is more resistant to rust and UV rays, lasting 25 years or more. It’s great for coastal areas or places with high temperatures, but it costs a bit more.
● Anodizing gives a metallic look and fits well with industrial styles, though it’s not the best at resisting scratches.
