1. Match Glass to Window/Door Types
Different Aluminium products need specific glass:
Aluminium Casement Windows: Use 5mm tempered glass for safety. In coastal areas, add laminated glass to resist salt damage.
Aluminium Sliding Doors: Pick 8mm toughened glass for panels larger than 3㎡. Thinner glass bends or cracks.
Aluminium Tilt and Turn Windows: Combine Low-E glass with double glazing (5mm+12A+5mm) for offices in hot climates.
Aluminium Arched Windows: Choose 6mm heat-strengthened glass to fit curved frames without breaking.
2. Confirm Safety Standards
Safety glass is non-negotiable for high-risk areas:
Tempered glass in Aluminium Doors and ground-floor Aluminium Windows must have a 3C certification mark.
For public buildings, glass in Aluminium Swing Doors needs an EN 12600 impact resistance rating.
Schools or hospitals using Aluminium Tilt and Turn Windows require Class P1A safety glass.
3. Focus on Energy Efficiency
Good glass cuts heating/cooling costs:
Double-glazed units (5mm+12A+5mm) reduce heat loss in Aluminium Sliding Windows by 30%.
Low-E coated glass reflects 90% of heat, ideal for Aluminium Arched Windows in sunny regions.
Avoid single-pane glass—it fails modern insulation standards.
4. Check Glass Thickness
Thickness depends on size and wind pressure:
For small Aluminium Casement Windows, 5mm glass works. Large Aluminium Sliding Doors need 8mm or thicker glass. Aluminium Arched Windows require at least 6mm heat-treated glass. Measure samples with calipers—some suppliers label 4.7mm as 5mm.
5. Avoid Common Mistakes
Weak hardware: Heavy glass in Aluminium Tilt and Turn Windows needs strong hinges (like Roto NT). Cheap hinges fail quickly.
Poor sealing: Gaps in Aluminium
swing door glass cause leaks. Demand silicone seals and butyl tape around edges.
Ignoring local rules: Example: UAE requires laminated glass for Aluminium Doors above the 10th floor.
Quick Tips
Ask suppliers for thermal transmittance reports (U-value ≤1.1 W/m²K) and sound test results (Rw ≥35dB).
For Aluminium Sliding Doors, keep glass weight under 80kg per panel to avoid crane fees.
Balance glass and frame ratios—70% glass to 30% frame works best for most Aluminium Windows.
By focusing on these points, buyers can source Aluminium Windows and Doors with glass that lasts. Whether selecting noise-blocking glass for Aluminium Casement Windows or hurricane-proof panels for Aluminium Sliding Doors, smart choices save time and money.
