When faced with violent storms and rains, home doors and windows will face a test. The airtightness, waterproofness and firmness of doors and windows have become the focus of everyone’s attention. There is no reason, especially when the rain is a little bit heavy, it is even more miserable, so that the floor and wall of the house are soaked.
Next, the editor will take you to solve these door and window problems together!
Leaking doors and windows
(1) Phenomenon
1. Leakage at the junction of door and window frames and surrounding walls.
2. Water accumulates in the sliding groove of the sliding window and seeps into the window.
(2) Reason
1. Use cement mortar to caulk the door and window frames and walls.
2. The glue injection between the door and window frame and the wall is not strict and there are gaps.
3. The door and window process is unqualified, and the combination between the window frame and the window sash is not strict.
4. The installation of the window sash sealing strip is unqualified, and water seeps through the cracks of the window sash glass.
5. There is no drainage hole in the outer frame of the window.
(3) Measures
1. No cement mortar should be used for caulking the door and window frames and walls. It should be connected elastically and sealed with sealant, and there should be no gaps.
2. Before installation, check whether the doors and windows are qualified, whether the connection between the window frame and the window sash is tight, and whether the installation of the window sash sealing strip is qualified. To
3. There is a gap of more than 50 mm between the window frame and the hole, so that the window sill can be used as a flowing water slope.
4. Drain holes should be drilled in the lower frame of the outer frame and the track root.
Keep the doors and windows from leaking
Water tightness and air tightness of doors and windows are the key to measuring quality. According to the actual engineering experience, pay attention to the following points, doors and windows will not leak air and water.
1. Since the general aluminum doors and windows are recessed, the top of the window must be dripping eagle beak to prevent the capillary phenomenon of rainwater from occurring.
2. The aluminum alloy doors and windows should be coated with a waterproof coating (asphalt) about 300mm from the side of the window. Before doing the waterproof coating, use the dust from the position to be coated and then apply the lead water oil.
3. Use waterproof concrete to seal around the windows. Please pay attention to adding waterproofing agent, because ordinary concrete loses water due to water reaction when it is solidified. The inside is porous, and water will seep into the room from the hole , And the inside of the concrete with waterproofing agent is dense and will not seep.
4. Waterproof sealant should be applied to the transfer position around the window frame and other materials.
5. All open windows should be covered with a drape to prevent rainwater from flowing into the room from the upward seam of the opening.
6. The glue seam between the window sill at the bottom of the window and the window should be designed to face outward instead of upward, and the window sill must also be designed with an outward slope.
7. If it is a single glass, the bottom of the window should be designed with a condensate diversion hole at a quarter of the glass.
8.The construction should strictly do a good job of the surrounding interface treatment.
For the airtightness of doors and windows, encryption treatment should be carried out on the places that are prone to infiltration and leakage. For example, waterproof sealant and waterproof coating should be applied to the docking parts; and when the internal concrete is sealed, special attention should be paid to adding waterproofing agent. In this way, the anti-seepage performance of doors and windows can be done very well!
