Curtain wall waterproof

    Reasonable design of curtain wall is one of the important measures of waterproof, the section design for pressure balance system, the system is based on the principle, design a external pressure in curtain wall into the internal guide hole, so that the inner and outer pressure adjustment to external balance is not easy to enter the water. At the same time, the outer edge of the profile and the lower part of the section are opened with small drainage holes to discharge a small amount of water or dew in the interior. The above waterproof and drainage measures together form a dry sealing system, on the one hand, it is not easy to enter the curtain wall. On the other hand, even if there is water infiltration, it will automatically exclude. In the preset hole, there are 2 on each cross frame, the hole is about 100mm around the corner, and the horizontal distance of the upper and lower holes is greater than 50mm to prevent the air collusion.
