Need drainage for doors and Windows?
What effect does the drainage system have on the system doors and Windows?
The function of doors and Windows is to shelter from wind and rain, so even the most traditional doors and Windows have drainage functions. In the structure of doors and Windows, although the profiles and glass are equipped with various sealing systems, small gaps at the interface are inevitable.
Watertight property
As one of the core performance indicators of doors and Windows, the ideal state pursued in the system design process is no water seepage and no water leakage. However, life experience tells us that nothing is absolute, and usually the system doors and Windows cannot ignore the drainage needs.
Scenario ①
The rain came suddenly, the doors and Windows were not closed in time, resulting in water between the window frames;
Scenario ②
When cleaning and maintaining Windows, water remains between window frames;
Scenario ③
In the case of aging, installation defects, etc., window tape may appear cracks in a rainy climate, resulting in water seepage.
What are the drainage methods of aluminum alloy doors and Windows
Drainage mode of aluminum alloy
1, open drainage, is to open a hole along the bottom of the window slot to the outside of the window frame. If there is water, it will flow through the hole to the outdoor side, and in order to prevent mosquitoes from entering through the hole, a drain hole cover will be fastened.
Advantages:
Smooth drainage, simple and effective;
The processing method is simple and convenient.
Cons:
The net plug of the hole is easy to be lost, and the material is usually easy to be damaged by aging;
The drainage hole is outward, which is easily affected by strong winds and leads to backflow.
2, hidden drainage, the principle of hidden drainage is to open a hole at the bottom of the window slot, the difference between the open hole and the open hole is that one opens to the side and one opens to the bottom, so that the water will flow into the window frame according to the water pressure, make a groove in the window frame, and the bottom hole is played on the groove, so that the water pressure is directly discharged to the outside.
Advantages:
Under the same rainfall, the drainage water pressure is higher and the drainage efficiency is higher.
Cons:
Industrial waste; From the outside, there will be a whole trench on the outside of the entire window frame, which is easy to sound when the wind blows in winter.
3, floor drain drainage, the principle is the same as the hidden drainage structure, in order to avoid the loss of the drainage hole cover, a hole is opened at the bottom of the window frame, and a hole is also opened on the outside of the window frame, and a special drainage hole cover plug is installed between the two holes, and the screw is played above to avoid loss and dislocation.
Advantages:
Smooth drainage, can achieve a certain extent of the "reverse" effect;
The drainage hole cover is tightly connected and not easily lost;
Even in windy weather, the special structural design guarantees that there will be no "whistling" problems.
Cons:
The processing process is complicated (opening two holes).
We believe that from the perspective of use experience, floor drain waterproof is a better choice! Because it minimizes the problems of drainage obstruction, isobaric pressure release, insect and ant wind prevention, it can also reduce the direct conduction of indoor and outdoor hot and cold air, and is also an improvement of the thermal insulation performance of doors and Windows.
Of course, the choice of this drainage method also has to bear the corresponding cost, you can be sure that the absolute value for money. Especially in high-rise buildings, or coastal and rainy weather areas, the choice of appropriate and high-quality floor drain is a necessary condition for doors and Windows, good water tightness so that doors and Windows are not afraid of heavy rain, block outdoor rain into the room to keep dry and comfortable.
