Have you fallen into these traps of doors and windows?

'The wind howled in the middle of the night, and the cracks in the window made a shrill whistle.”

"The rainstorm suddenly hit, and fine water droplets seeped out of the window frame.”

"The newly installed heat insulation aluminum window had loose handles and stuck tracks within less than a year.”

Do these troubles make you irritated just by hearing about them?

01 SECURITY LINE

"During a typhoon, other people's houses were motionless, but your windows seemed to be 'breathing'? " If the wind pressure resistance level does not meet the standard, the glass may be deformed or leak, or even burst.

DODGE A PIT

For coastal/high-rise residents, it is necessary to select a wind pressure resistance level ≥ 6 (national standard GB/T 7106) and a profile wall thickness ≥ 1.8mm, and a multi-cavity design for the cavity structure.

02 CAVITY STRUCTURE

Multi-cavity structure: The more cavities, the stronger the sound insulation and heat insulation performance. For example, an independent drainage cavity can prevent water seepage, and a thermal insulation cavity can effectively block heat transfer.

03 WATERTIGHT and AIRTIGHT

Are you fighting wits and courage with water stains in window seams every rainy season? Insufficient watertightness = spending money to buy a water curtain cave, poor airtightness = double the air conditioning fee.

SELECTION TIPS

Look for 6063-T5 original aluminum, smooth cut without burrs, PA66 nylon for insulation strips (no PVC!), profile width at least 108 series, 120 or more is recommended in the cold winter areas.

04 SAFETY BLIND SPOT OF 80% OF GLASS

"Is the hollow glass fogging? Maybe you bought 'glue glass'!" Poor quality glass is the culprit of poor sound insulation and self-explosion.

DODGE A PIT

3C certified, glass thickness ≥5mm, hollow layer 9-27mm is better, argon gas is filled for better insulation, and street-side residents should choose three-glass two-cavity + laminated glass.

Doors and windows are the "guardian angel" of the home, not fast-moving consumer goods. Choose the right one once and use it for 20 years. If you are greedy for cheap, you may get a nightmare of maintenance every year.
