What should I pay attention to when customizing home improvement doors and windows in cities with rainy weather in the region?

When buying doors and windows, we should pay attention to the function of hidden drainage holes.

1 The drainage hole is vertical downward, with large drainage power and large flow.

Change the characteristics of horizontal outward drainage hole in the past, change the hidden drainage hole into vertical downward drainage, and drain by vertical downward gravity, which greatly improves the drainage pressure. In addition, rainwater can be discharged around the whole drainage hole, which is larger than the original horizontal drainage area. In other words, vertical downward drainage is faster, water flow is more smooth, and water blockage is avoided.

2 Avoid direct wind blowing.

Avoid the wind blowing directly to the drainage hole, and reduce the chance of rainwater being poured backwards by the wind.

No need to install a drain cover, which is more beautiful.

The traditional drainage hole is not beautiful, and the installed plastic cover will age and fall off after a long time outdoors. Hidden drainage is to hide the drainage hole, so the hole can't be seen outside, so it is more beautiful.
