When it comes to the troublesome problems in home improvement doors and windows, the term "door and window leakage" is definitely on the list.
Many consumers only find out that there are hidden dangers of water leakage in the doors and windows of their homes after they have moved in for a period of time.
Annoying door and window leakage, is it the "distortion" of the profile or the "loss" of the structure? In this issue, let’s walk into the home improvement door and window leaking water, what to do when waterproofing is in progress...
Baydee believes that there are four main reasons for the "leakage" of home improvement doors and windows:
The first point is the structure of doors and windows. The impact of structure on performance is the same as the impact of genes on growth and development. When heavy wind and rain strikes, door and window products with better water tightness, air tightness, and wind pressure resistance will theoretically reduce the occurrence of water leakage problems probability.
So what kind of structure has better water tightness and other properties? Friends can ask the merchant for the formal test report of this series of doors and windows products to find the corresponding performance.
The second point is the quality control of doors and windows. The impact of quality control on performance is just like the impact of the acquired environment on growth and development.
Processing factories with excellent quality control often choose high-quality rubber strips, heat insulation strips and other raw materials to ensure stable performance. We will build our own strong wind and rain experience room to continuously test and improve product structure and processing standards.
Note: Drainage holes are the main way for doors and windows to drain water, but there may be cases where the drainage holes are not opened at the end of the drainage holes, or the drainage holes are opened too high, which will also cause water seepage in doors and windows.
The third point is the installation of doors and windows. This is the easiest thing for friends to attribute. Often, as long as water leaks in, everyone will say: Oh, your window decoration is really not good, and it will leak.
Whether the installation is good or not is indeed a very important influence on the water leakage of the doors and windows, the waterproof glue between the door and window frame and the wall, the degree of fit between the glass and the window frame (leaf), and the gap between the window sash and the window frame when the window is closed. The degree of fit between them and so on need to be precisely controlled during installation.
If any link is missed, it is difficult to guarantee that there will be no water leakage for products with top watertight performance and top production and product control.
The last point is whether the building itself is leaking. Is the waterproof layer of the wall around the window frame damaged, is the window sill outside the door and window easy to store water, and is there any large area of glue cracking on the dry hanging and aluminum wall, causing rainwater to bypass the window and flow into the room?
Baydee believes that the water leakage problems caused by the first three reasons are the easiest to repair, but the leakage problems near doors and windows caused by the damage of the building's own waterproof layer have a high probability and are troublesome to deal with.
The doors and windows of some old residential areas have experienced ups and downs for more than ten years, and the vigor (performance) has been almost exhausted in these years. The waterproof layer near the window frame has also been cracked and damaged due to aging. Then go to resist the rain from the outside world.
The application of exterior wall glue on the door and window frame is also critical to the water leakage of the door and window. The exterior wall glue used for home improvement is of poor quality, which directly reduces the service life.
A lot of water leakage problems have occurred because the glue masters did not do a good job of sealing the outside due to problems such as insufficient glue application, missing glue application, and indiscriminate use of glue in the construction.
In fact, when it comes to solving the water leakage of doors and windows, in the final analysis, it is about how to classify (distinguish), how to look (details and construction) and how to choose (the optimal solution after comprehensive consideration) for our own doors and windows.
To purchase doors and windows from the processing end, we must ensure the strength of the processing end.
When purchasing, we should pay attention to the drainage method of doors and windows. Concealed drainage is not the best (some large fixed window sashes need to arrange multiple drainage holes, and it will affect the appearance if they are made into open drainage holes), as long as the drainage path is arranged reasonably.
It is also necessary to pay attention to whether the positions of the drainage holes on both sides are different from left to right, and whether the drainage holes are properly treated against insects.
Or directly ask the merchant to issue a door and window factory certificate to confirm the strength and quality control of the factory, as well as the performance test report of the door and window, confirm the airtightness and watertightness of the door and window, and ask whether there is waterproof treatment for the seams and glue injection holes. Apply end glue.
It is necessary to confirm before purchasing and installing, if there is a problem with the product itself, who should be responsible for the maintenance and replacement costs of doors and windows.
On the windowsills of our own doors and windows, we must pay attention to setting the water slope before design and construction. The inclination of the slope is determined according to the size of the reserved window sill. The wider the window sill, the greater the slope (generally, the slope is about 5° ~ 10°, not less than 5 %).
After the window sill has a certain slope, whether it is the gap caused by the old window's disrepair or the gap left by the installation error of the new window, the gap must be "filled".
In this link, the quality of the selected sealant is particularly important. The simplest and most effective way is to look for the brand to purchase.
After choosing the right assistant, the master gluer made the glue twisted and twisted in practice, which affected the appearance; the place where the glue should be glued was missed, and it was perfunctory, which did not have a waterproof effect on the doors and windows.
Therefore, we must pay attention to the effect of the master's glue application, and if we find any gaps, we must quickly ask him to fill them up, so that the sealant can play its due role.
For the remedy of the waterproof layer of the external wall, we can take the measures of brushing waterproof paint. Where there is obvious damage to the exterior wall, it should be repaired in time and a layer of waterproof material should be applied between the window frame and the window sill.
1. Sliding window leakage
The general sliding window type is slightly inferior in terms of airtightness and watertightness. When the outdoor wind and rain are too strong to exceed the upper limit of the sealing performance of doors and windows, rainwater leakage will easily occur.
However, if it is installed on the washing balcony, most Peng friends will be more "tolerant" to its watertightness requirements.
Perhaps it is thought that the windows of the balcony only need to ensure the most basic safety and weatherproof functions, even if there is leakage, it will not be too annoying.
Safety is the first element in the sliding window type for washing and drying balconies, and there is no need to spend more money on performance improvement. Faced with this demand, you can choose local more reliable door and window products to reduce costs and pursue more. High cost performance.
If you are a Pengyou with a sufficient budget and want to choose a better performance while ensuring safety, of course it is a No problem.
In addition, if the location of the drainage holes is incorrect or the number of settings is unreasonable (it is rainy in the south, the design of drainage holes can be more than that in the north), which will cause leakage of doors and windows.
The number of drainage holes should be determined according to the separation size of doors and windows:
2. Window leakage
Rainwater seeps into the room from the window frame, which is usually caused by improper construction of doors and windows. There will be a certain gap between the wall and the window frame, and the gap must be filled.
The smoother the installation hole between the window frame and the wall, the more convenient it is to fill and seal afterwards, reducing the risk of water leakage.
After all, consumers still need to confirm the measurement size before design with the construction master. Accurate size can save a lot of trouble for subsequent construction. After all, every additional gap between doors and windows in the home will give rainwater an extra chance to intrude into the room. We must pay attention to the location of the opening where the doors and windows are installed.
3. Corner leakage
The corners of the doors and windows are not injected with glue or the glue is not fully injected, causing the rainwater entering the top of the profile to pass through the corner injection holes, and at the same time flow into the inside of the window, and drip out from the installation holes and other positions.
Or there is a gap between the profiles, and rainwater enters the inside of the window through the gap, resulting in leakage of doors and windows.
When purchasing, we must pay attention to the quality control of door and window products, and the group corners are neat; brush the end glue on the cross-section of the group corners to ensure that the overall strength and sealing of the corners of doors and windows are not enough to prevent the penetration of rainwater.
4. Glass leaks
In order to avoid direct contact with the glass tank during installation, glass cushion blocks will be installed around the glass. The cushion blocks should not block the drainage holes and drainage channels.
In the installation of doors and windows, we can go directly to the site to see the scene, which makes us feel more at ease.
Rainwater may also enter the cavity of the fan profile from the outer rubber strip of the glass, resulting in leakage of the door and window.
When encountering this situation, there are two commonly used solutions - rubber strips and glue seals. When the quality of the glue and the strip and the construction level of the workers are on the same level, there is no difference between the glue and the glue, and it is still necessary to analyze the specific situation.
When purchasing, we can directly ask the merchant whether the glass is glued or glued, what should be done if it is in a typhoon area, and what is the solution.
In the typhoon-prone rainwater-infested area, the glue strip is not safe enough, and the glass is easy to move indoors under strong winds. It is recommended to use the glue method to be more secure.
When we buy doors and windows, we should also pay more attention to the way of pressing the glass, and ask more questions.
If the crimping line of the glass is inserted into the notch and fixed by the buckle by pushing horizontally, the fixing strength is not as good as that of the crimping type installed directly. Under the attack of a super typhoon, the glass may shake or even fall off. , not to mention leakage.
5. Drip line or drip tank design
At the design end of doors, windows and sills, the existence of drip lines or drip grooves is not well known and concerned. They are also drainage measures set up in home decoration to prevent rainwater from flowing down the wall back into the window.
This should take into account the actual use of the scene, really can not follow the installation master's will to install, pay attention to whether the master's installation is reasonable at the construction site.
In order to prevent the wind and rain when the doors and windows are opened, the position of the opening fan should not exceed the eaves, and the installation position of the doors and windows should not exceed the drip line above the eaves.
The width and depth of the drip tank should not be less than 10 mm. If there is no drip line at the window position, it should be installed within a few centimeters of the eaves.
6. Leakage of the outer wall
In the construction of doors and windows, if there is no effective waterproof seal between the outer window and the opening, it will leave hidden dangers of leakage indoors.
For the filling of the gap left by the outer wall around the window frame, some masters are perfunctory and use ordinary cement mortar to deal with it, but this will lead to cracking of the wall.
Therefore, we need to purchase waterproof mortar for the leakage treatment of the external wall, and also apply anti-crack mortar on the insulation layer.
7. Selection of ceramic tiles and window sills
When there is a leakage problem on the outer window sill, some consumers will choose to use ceramic tiles for waterproofing.
In the purchase of tiles, we have to choose long strips in terms of style, because the shorter the tiles, the more gaps there will be, which increases the possibility of leakage.
However, high-level officials do not recommend using tiles for waterproofing. Over time, tiles may cause falling hazards.
At this time, we considered changing the aluminum alloy window sill, the window sill is better matched with the doors and windows, and it will not flow directly from the window sill to the wall, which is easier to take care of.
