Your window insulation, buy doors and Windows do not be cheap!

Weather temperatures rise sharply, doors and Windows ushered in a huge test, doors and Windows of the tightness, waterproof and solid become the focus of attention, doors and Windows inexplicably leak, can not find the reason, especially the rain is a little more miserable, the home floor and wall are soaked, where the problem?

1. Frame fan matching problem

Traditional door and window production process: cutting - fixed aluminum lining - drilling and milling fan handle hole - welding - Angle cleaning - hardware installation - assembly. In the traditional production process, workers rely on themselves to control the deviation of each component, which causes the cumulative error of the window to be larger and larger. The window frame and sash of the door and window are sealed by lap joint. The lap part of the fan and frame is called lap amount. Due to the deviation of the size of the window frame and sash, the deviation of the straightness of the window frame installation, etc., the actual lap amount of the window frame and sash will change. When the amount of lap of the frame fan is reduced, the sealing performance will be reduced, and the amount of lap is too small, and the risk of the door and window falling off will be increased.

2. Aging and falling off of rubber strip

The sealing strip is installed in the door and window frame, fan and glass, relying on its outstanding elastic function of the door and window profiles, hardware, glass closely linked together, into a whole, according to the basic principle of the isobaric planning of energy-saving doors and Windows, play a sealing isobaric role, so as to achieve the door and window of the three specifications and energy-saving specifications, poor quality of the rubber strip aging resistance is poor, After long-term exposure to the sun, the rubber strip becomes hard after aging, loses elasticity, and is easy to fall off, which not only affects the insulation and energy saving effect of the house, but also relates to the waterproof performance of the wall.
