Three common problems in door and window installation and its treatment

First, the color difference between doors and windows is obvious

(a) Phenomenon

The color of the adjacent doors, windows or window frames does not match the color of the fan.

(b) Reasons

Material is not the same factory product, or the same batch of products, or different grades of products.

(III) Measures

1, the purchase of profiles should use the same manufacturer's products, and once prepared enough material.

2, pay attention to the color of the ingredients before cutting, to avoid the color difference of the material used in the same window.

Second, door and window leakage

(a) Phenomenon

1. Leakage between the door frame and the surrounding wall.

2. The sliding window slides into the water in the trough and penetrates into the window.

(b) Reasons

1. Door and window frames and walls are cemented with cement mortar.

2. The gap between the window frame and the wall is not strict and there is a gap.

3, doors and windows process failed, the combination of window frames and sashes is not strict.

4. The sash seals are not installed and the water seeps through the sash's glass joints.

5. There is no drainage hole in the window frame.

(III) Measures

1. Door and window frames and walls shall not be caulked with cement mortar. Should be flexible connection, sealed with sealant, no gaps.

3. There is more than 50 mm gap between the window frame and the hole so that the window sill can be used as a water flow slope.

4. Drain holes should be drilled in the frame and track roots.

Third, the overall window and door frame stiffness difference

(a) Phenomenon

Sliding or opening doors or windows or encountering windy weather, the door and window frames are shaking.

(b) Reasons

1. Incorrect profile selection, small section, and insufficient strength. The prevention of aluminum alloy door and window materials does not meet the requirements. Plastic steel door and window material quality failed.

2, steel doors and windows of the inner lining steel configuration does not meet the standard, (usually steel lining to use 1.20, but because the installation up to the owners can not see. Many businesses use unqualified to the owner to install) steel wall thickness, poor strength; The lining steel is inserted in sections, which does not form an integral reinforcing effect; the lining steel and plastic profiles are not firmly connected.

3, the installation node is not in accordance with specifications.

4, did not use different fixing methods according to different walls.

(III) Measures

1. The specifications and quantity of door and window frame profiles conform to national standards. The thickness of the outer frame of the aluminum alloy profile shall not be less than 2.4 mm. Plastic window material thickness should not be less than 2.5 mm.

2, check the appearance of plastic profiles, qualified profiles should be white or white ivory, clean and smooth. Better quality protective film.

3, according to the size of the door and window openings, installation height selection profile section, flat window is not less than 55 series, sliding window is not less than 75 series.

4, strictly in accordance with the provisions of the provisions of the installation, to ensure solid and stable.
