Aluminum alloy window acceptance considerations
The installed aluminum alloy window should be closed tightly and the gap should be even; the deviation between the sash and the frame or the parallelism of the adjacent side of the adjacent fan should not exceed 2 mm, and the opening is flexible and easy to use.
Sliding the window, see if the glide path is installed flat, be careful not to have bumps, and gently push the window to slide freely.
The frame and cross frame of the aluminum alloy window of the balcony must be firmly fixed on the balcony railing and the top of the balcony. It is usually fixed in the concrete with nails or rivets, and is reinforced with painted angle steel when fixing. It can't be fixed on the brick wall, and it can't be fixed by the top and bottom of the wooden wedge instead of the nail gun. The gap between the upper glide path and the top guardrail should be filled with cement mortar to prevent rainwater from entering the room.
The wall thickness of the aluminum alloy window profile shall not be less than 1.2 mm, and the joint thickness of the aluminum alloy window frame and the wall shall not be less than 1.5 mm.
