In the past few years, typhoons have occurred quite frequently. It is a great test for the waterproofness of ordinary family doors and windows. The waterproofness of doors and windows is not good. It is easy to cause property losses and unnecessary troubles on typhoon days, so find a waterproof one. High-quality door and window products are extremely necessary, so which type of door and window is better in water resistance? In the comparison of many types of doors and windows, aluminum-clad wood doors and windows have great advantages in water resistance.
Water leakage problems in doors and windows are mainly caused by the following aspects:
1. There are defects in the structure of doors and windows;
2. The construction and installation are not standardized or standard;
3. The hardware accessories are unqualified;
4. The sealing treatment of the connection part is not in place.
What are the advantages of waterproofing aluminum-clad wood doors and windows?
1. Water-based paint
The interior wood of aluminum-clad wood doors and windows is made of water-based paint imported from Germany, and through multiple paint processes, the overall surface of the window feels smooth and soft, has excellent waterproof and breathable performance, is not easy to fade, and has good weather resistance. It is sealed with two primers and two top coats, which seal the wood from the air, moisture, and corrosion, ensuring it stays dry.
One layer of primer: can delay the service life of the paint film, and prevent moths, insects, and mildew; two layers of primer: clear texture, translucent topcoat, and prevent the paint from fading.
First-level topcoat: it plays a major decorative and protective role in the paint film; second-level topcoat: the outer layer of the paint layer affects the quality of the entire paint film.
2. Concealed drainage
The aluminum-clad wood doors and windows adopt a hidden drainage design and introduce the concept of an isobaric chamber to ensure the free flow of water without sucking back. Even on rainy days, the drainage can be smoother.
Generally speaking, under the action of wind, the outdoors often generates pressure on the indoors, and rainwater will seep into the indoors along with this pressure. Add a sealing strip in the center of the window sash and the window frame, the outside is a watertight chamber, the inside is an airtight chamber, and an equal pressure chamber is formed on the outside. The pressure in the equal pressure chamber is equal to the outside pressure, which can prevent rainwater from entering the room. And the rainwater flows out to the outside by its own gravity.
3. Sealing strip
Aluminum-clad wood doors and windows use high-quality sealing strips and use anti-aging and elastic sealing strips between the window sash and the window frame and between the glass and the window sash. The material meets the physical performance indicators specified in the national standard regulations. When the doors and windows are closed, the rubber strip can be well pressed on the window frame, and the sealing performance is strong, so as to reduce the possibility of rainwater penetration.
4. Aluminum
Generally speaking, there will be gaps at the joints of the four corners of traditional door and window sashes, as well as the joints between the mullion and the window frame. If the machining accuracy is poor and the angle error is large, the gap will be large and it will be easy for water to enter. Aluminum-clad wood doors and windows adopt seamless welding technology, with higher processing precision, so that the joints are closely matched, and the gaps are extremely small, preventing rainwater from penetrating into the room through the gaps.
