ã€China Aluminum Network】 Aluminum alloy window sill has no drain hole at the lower part, which allows the water in the aluminum cavity to flow out automatically; the inner edge plate of the sliding window bottom frame is not higher than the outer edge plate, and the water is also easy under the action of the wind. Cross the guide rails and enter the room; the aluminum joints are not buckled or sealed with sealant, causing rain to enter the cavity along the holes and leak into the wall.
