Lightweight and thin in nature, the main aim of the curtain wall is to protect the inside structures from any damages that could be caused by external factors such as dust, rain, etc. The curtain wall works on the mechanism of carrying its own weight and the weight of the external factors is transferred to the building’s structures. Being air and water resistant, they save the consumption of electricity as well. Below are the steps explaining the draining out of the water from the curtain wall.
Made up of silicon, neoprene or EPDM, the curtain wall has a cap bead which assists in filling up the empty space situated between the glass and the pressure profile. The curtain wall chosen must have a silicon cap as it prevents the UV rays from entering the buildings. The cap bead is usually installed in compression as it leads to the expansion of the beauty cap. Due to heat, the beauty cap expands which decreases its capacity to hold the glass further and creates space for the accumulation of snow and ice as well. In order to equalize the pressure in the pressure cavity, it has holes as well. This cavity helps in draining out the accumulated air pressure. These holes help in the unidirectional movement of the air and water leading to the movement of water from the mullion to the transom. This water is finally let out through the holes of the beauty cap and the pressure profile.
