The wind is strong in the south, and the coastal areas are often afflicted by typhoons, so the products must be strong in terms of wind pressure resistance. The wall thickness, frame width and thickness of aluminum profile of doors and windows should be strengthened.
There is much rain in the south, so the water tightness of doors and windows should also be good enough to prevent rain leakage. However, the humid weather in the south is unfavorable to wood, so aluminum wood doors and windows are not as popular in the South as in the north. In addition, in order to prevent rainwater from entering, it is best to choose high and low rails for the lower rail of the balcony sliding door.
There are many mosquitoes in the south, which are easy to infect diseases, so it is best to install windows with screens, such as casement windows with integrated screens.
