How to Choose Aluminum Alloy Windows & Doors

Avoid Traps to Build a Safe and Comfortable Home

Windows and doors are the "eyes" of a home, influencing not only its aesthetic style but also core needs like safety, sound insulation, and energy efficiency. With countless aluminum alloy window and door products on the market, how can you avoid common pitfalls? Master these six key points to effortlessly choose high-quality, cost-effective products!

Check Profile Quality

#Meet Thickness Standards

National Requirements: According to the Aluminum Alloy Doors and Windows standard (GB/T 8478-2020), the main profile wall thickness for exterior windows should be ≥1.8mm, and ≥2.2mm for exterior doors .

#Choose Primary Aluminum: Opt for 6063-T5 primary aluminum, which has a smooth surface without grainy texture. Avoid recycled aluminum

Thermal Break DesignThermal break profiles use insulation strips to separate inner and outer aluminum layers, reducing heat transfer by over 30% and improving energy efficiency.

Glass Configuration

#Tempered Glass is Essential

Look for the 3C certification. Tempered glass shatters into harmless granular pieces, enhancing safety.

Recommended configuration: "5+12A+5" double-glazed glass (two 5mm panes with a 12mm air gap) for superior soundproofing and insulation.

#Inspect Details

Ensure glass surfaces are smooth and scratch-free. Check for dust, moisture, or warped spacers in the air gap.

Hardware Components

#Premium Brand Hardware

Hinges, locks, and sliding rails should be from reputable brands for corrosion resistance and load-bearing strength.

Test on-site: Smooth operation, quiet sliding, and tight lock engagement.

#Sealing Strips Matter

Use EPDM (Ethylene Propylene Diene Monomer) rubber strips for aging resistance, temperature tolerance, and enhanced airtightness

Craftsmanship

#Joints and Welding

High-quality products have seamless joints and polished welds without cracks.

Low-quality issues: Warped frames, gaps causing drafts or leaks.

#Surface Finish

Check profiles for dents, bubbles, scratches, or uneven coloring.

Brand and Service

#Beware of Low-Cost Traps

High-quality products have higher costs. Items priced 30% below market rates may cut corners.

Choose certified brands offering 10+ years of warranty.

#Detail-Oriented Contracts

Specify profile models, thickness, glass configurations, etc. Retain test reports as evidence for disputes.

END

Windows and doors are long-term investments-never compromise quality for price. Follow the principle: "Check materials first, verify craftsmanship second, test performance third." Pair this with brand reputation and after-sales service to build a safe, energy-efficient home. For further questions, leave a comment-we're here to help!
