Can you use foaming agent for door and window caulking? Will it loosen after a long time?

I think the foaming agent used for door and window caulking is not very good, because the service life of the foaming agent is very short, and the effect of use is not particularly good, and its reinforcement effect will slowly weaken after a long time, and it may loosen.

Of course, blowing agents can be used. The blowing agent is still very strong and will not loosen, and most of the decoration will now use the blowing agent.

Personally, I think it is best not to use foaming agent for door and window caulking, because it is likely to cause the doors and windows to loosen over time, which is not conducive to our safety.

Summary. The first method is to cut flat the styrofoam that has spilled out of the window frame with a knife after curing.

The reason is that styrofoam only plays the role of filling, not waterproofing. The second practice is: before the styrofoam that overflows the window frame is cured, a special tool should be used to back pressure the plug into the seam 5-8mm, and it is strictly forbidden to cut with a knife.

The reason is: after the styrofoam cures, a layer of film will be formed on the surface, which will play the role of waterproofing and isolating oxygen, and the outer surface of the styrofoam will be damaged after cutting.

Hello dear, not necessarily.

The first method is to cut flat the styrofoam that has spilled out of the window frame with a knife after curing. The reason is that styrofoam only plays the role of yard collapse filling, and it is not waterproof for rock acceptance.

The second practice is: before the styrofoam that overflows the window frame is cured, a special tool should be used to back pressure the plug into the seam 5-8mm, and it is strictly forbidden to cut with a knife. The reasons are:

After the styrofoam cures, a layer of film will be formed on the surface, which will play the role of waterproofing and isolating oxygen, and after cutting, it will destroy the outer surface of the foamed rough mold, and the void is not closed and easy to absorb moisture, and it will be pulverized in contact with the air for a long time, resulting in a gap between the window frame and the wall home.

The joints of windows and doors are usually made of cement slurry or styrofoam, but the price of styrofoam will be more expensive than cement slurry, so more and more decoration masters will recommend the use of cement slurryFirst of all, cement slurry is a very traditional usage, and the application of cement slurry will be stronger, but its service life will be shorter. If the sun is shining for a long time, it is very easy to crack, and if it is exposed to the sun and rain, it will gradually crack, which is very unsightly. Not only that, but the cement slurry is also very easy to corrode the aluminum window, and the long-term corrosion will cause the window to fall immediately when it encounters strong winds, which has a certain danger.

Therefore, it is the application of styrofoam, which has very loose material characteristics, can meet very well with windows and doors, and has good wind and waterproof characteristics, is also more energy-saving and environmentally friendly, and has a long service life of the application. Especially in the northern region, most of the aluminum windows are used, so it will be best to use styrofoam, although it is more expensive, but fully consider the use and service life, etc., or styrofoam is more cost-effective. The open interior space is laid out with a lot of unobtrusive soft decoration design.

The cashmere wool lattice curtain fabric at the head of the window achieves light blocking and is also mixed with a hint of warmth. The curtain cloth dominated by dark brown does not lack a sense of transparency due to the interrelationship between the materials, and the gas and the sun flow freely.

In addition, many people think that styrofoam can be used to fill no matter what gap there is, but in fact, there are certain misconceptions about these views. Styrofoam belongs to flexible connection, which can avoid extrusion and deformation caused by forced connection, and is a particularly scientific and reasonable filling material, but whether the gap between windows and doors should be selected styrofoam or concrete should be determined according to the number of gaps. The gap between the window and the wall is less than five cm, it is proposed to use styrofoam to fill it first, and for outdoor windows, it is also necessary to make a layer of moisture-proof in the outermost layer to avoid soaking foam in rainy days and precipitation.

When the gap exceeds five centimeters, it is necessary to fill the bricks or use concrete to carry out the filling. The purpose is to ensure that the gap between the wall and the window is tight and impermeable, and after filling with concrete, it is necessary to make a layer of moisture-proof in the outermost layer. In addition, it is important to note that one thing is important:

Concrete has a certain corrosive effect on metal aluminum, which is very easy to cause deformation of aluminum windows and doors. It is proposed to use polyurethane plastic foam for filling, and use silicone sealant on the outermost layer to carry out sealing solutions to prevent the entry of water mist. However, although it solves the problem of cracking concrete, considering the overall appearance, we must pay attention to the color matching skills between the wall, window and door and sealant, and choose the same or similar color tones as much as possible to produce an overall beautiful practical effect.

The choice of caulk is to choose styrofoam as much as possible, styrofoam is a very energy-saving and environmentally friendly soft colloid, in fact, it smells a lot more convenient than cement slurry, and can make the filling of the gap in the window do not leak, not only has good thermal insulation performance, but also basically there can be cracks and water seepage, and the wrong choice may make the doors and windows fall dangerously.

But the use of cement to fill can not make the void reach a full state, there must be expansion joints for a long time, in case of rain caused by the dampness of the inner wall, the gap between the window frame and the wall is less than five cm, you can use styrofoam to fill, the outer sore should also be made in the outermost layer of waterproofing, to prevent rainwater from soaking styrofoam in rainy days.

For the installation of some indoor doors and windows, we will find that many of them are fixed with foam. So are the foamed and fixed indoor doors and windows firm and safe? This is also a question that many of our friends are worried about.

Take the following problems as an example to analyze the installation of doors and windows of some special materials in the interior.

The characteristics of the so-called foaming filler are a characteristic formed after the foaming caulk is filled to the aluminum alloy doors and windows, which determines the effect it can achieve. From this point of view, the foaming caulk cannot fix the aluminum alloy door and window covers. It is embodied in the following two points.

What the blowing agent can achieve is to fill the gap. This means that after we fill the aluminum alloy door and window cover with the reserved opening, the styrofoam can fill the entire gap. Then realize that the aluminum alloy door cover is almost sealed between the Yuyu and the wall.

Therefore, it can realize the simple fixing of aluminum alloy door and window covers, but it cannot ensure the firmness of aluminum alloy door and window covers.

Although the foaming agent fills the gap, it is impossible to guarantee the tie force between it and the wall and the aluminum alloy door boring sleeve. In other words, our aluminum alloy door and window sleeves can easily separate from the openings in the wall after being shaken. This will also lead to the final loosening of our aluminum alloy doors and windows.

If there is noise, it may fall.

The characteristics of the so-called aluminum alloy door and window sleeve are the characteristics of the aluminum alloy door and window sleeve itself in terms of size and material. The characteristics of these two aspects also determine that effective fixation cannot be achieved by using styrofoam fixation. Specifically, it is reflected in the following two points.

: The characteristics of the size of the aluminum alloy door and window sleeve are determined. Like the aluminum alloy door and window covers used in our home decoration, they are not particularly large in terms of the cross-sectional size of the profile.

Unlike our interiors, the width of the door casing is very wide. As a result, the contact surface between the aluminum alloy door and window cover and the opening is limited, so it is almost impossible to use styrofoam to completely fix the limited contact surface.

The material characteristics of aluminum alloy door and window covers also determine that we cannot use foam caulk to fix them directly. Because the characteristics of aluminum alloy door and window sleeves themselves are very hard, because it is a metal material. The aluminum alloy door and window sleeve made of metal material is only connected with the original hole through flexible foaming, which is very easy to cause the loosening of the aluminum alloy door and window cover.

In the later period, the whole door and window were separated from the original opening.

Of course not. In this case, there will be problems later. Aluminum alloy doors and windows are firmly established by relying on the holes and fits firmly with the wall, and the foam caulk only ensures that there is no air leakage.

However, if Wei Zhenguo Zhenli completely relies on caulk to fix, there will be a lot of potential safety hazards in the later stage.

I think of course it's not strong, and it will be 100% wrong in the later stage, so it's better to fix it with screws.

I think it's very strong and there are no problems, and now these doors and windows are almost always fixed with foaming agents.

The door and window cover of aluminum alloy profile is fixed by foaming agent, and my personal opinion is that if all of the door and window covers of aluminum alloy profiles are filled and fixed by foaming agent, there is no doubt that they are not strong, and the installation of aluminum alloy door and window covers is not allowed to be fixed with foam plastic filler immediately.

1.The direct reason, the main reason often said here is that we are not allowed to use styrofoam to fix the aluminum alloy door and window covers, and the most essential factor is that the styrofoam has no connection effect. For styrofoam, we all know that after we fill the gap, it can swell on its own, so that the window will not move.

However, the most important effect it plays is actually the sealing of cracks, but it does not have very good tensile resistance. Under the hazard of external force, it is very likely that the styrofoam will be separated from the wall or window. Therefore, it is not allowed to apply styrofoam to fix the doors and windows immediately.

2.The installation of aluminum alloy door and window cover is assembled in the edge of the hole, and in the assembly link, there is a gap between the door and window cover of the aluminum alloy profile and the edge of the hole. For example, one of the most common conditions is that the foam filler added to it is loose, so there is a leakage of water and ventilation.

3.There are obvious security risks, why do they have obvious appearances? It refers to everyone's aluminum alloy doors and windows, and if only the foam plastic filler is used, that is, the styrofoam is fixed, his hands are also very limited.

For example, in the most common situation, when the wind speed is particularly high, if there is a push on the side of our window, then it is very likely that the window will immediately fall from everyone's living balcony. In other words, problems such as balcony doors and windows are also more serious.

4.There is also a possibility that the window may fall down, which means that if we use the window, there is a high chance that we will accidentally fall down with the window. For example, the most common situation, the laminated glass in many high-rise residences today, in the tidy process, many people are standing on the window, pulling the window with one hand.

In this case, if our windows are not reasonably fixed to the wall, only styrofoam. Then it is very likely that the tensile force of the body will be driven, and it will fall down with the window, so it is very dangerous.

Summary. Hello dear! Styrofoam can be applied to the cavity of aluminum alloy doors and windows.

Improper use of foam glue will cause corrosion to the application items, so it is necessary to pay attention to the correct use; The adhesive surface is dusted and kept clean; After gluing, let it dry for 20 seconds, then close it to make it instantly firm. Due to the different temperature and humidity, the drying time is also different, the observable method is to dry for 5 seconds, and then touch the adhesive surface every second to pull it apart, and wait for 3 seconds to close after seeing the phenomenon of "drawing".

Due to the different temperature and humidity of the key cavity, the drying time is also different, and the observable method is to dry for 5 seconds, and then touch the adhesive surface every second to pull it apart, and wait for the stool to do it for 3 seconds after seeing the phenomenon of "drawing".

It can be cleaned with a high concentration of thinner --- banana water, but the surface of the material must not be painted, or the color of the paint will be brushed off with it. Use the small shovel used to brush the wall and the cement to scrape off the layer of foam attached to the surface of the glue without worrying about scratching, and then use an oil brush to dip incense and banana water on the glue after brushing off the foam, and first resist the song for a while.

What are the disadvantages of relying on foam caulk for doors and windows? Foam injections can address the subtle openings and keep them hot and tight. Foam sealants (also known as foam adhesives) are used to join aluminum windows and doors, so you can leave Master IR directly and tell the person responsible for handling the windows and doors that they are safety-related.

If you can't do it, don't do it. Not a single irresponsible person was found to install it. It all depends on the foam.

Normally, we will first go to the door and window store to process and customize our favorite materials and stripes, or go to the onde store to distribute the labels, and choose to have them made by the factory.

<> factory production cycle is longer compared to individuals and factories. , use polyurethane foaming agent groove to deal with the installation gaps of various filling decoration processes, and reach the MS point that can be seen everywhere; It can be said that in the installation and construction of all newly renovated houses, the filling method of polyurethane foaming agent is basically inseparable; Install aluminum alloy door and window covers to prevent robbery and falling; So the question is: Are aluminum alloy doors and windows securely fastened with foam sealant?

Today, for this question, fixing a window cover does not guarantee your firmness.

Sealants can only be used to fill gaskets to ensure some degree of stiffness, but there is no legal operation. However, such accidents can be avoided if the windows are installed firmly. Others sit in the sun and lean against the window, as well as when they clean it.

Various situations are caused by the inertness of aluminum alloy windows when they are installed, and aluminum alloy windows are an adhesive.

Good products have a strong grip and strong adhesion, but for heavy objects with hard words, it is certainly unrealistic to maintain and correct them with foam alone, and the grinding is unstable and strong. With the progress of science and technology, caulk is subdivided into a variety of products: from white cement to caulk, to beauty dust dismantling caulk, porcelain caulk, genuine leather porcelain cola, etc., in the decoration process, the space is rearranged, and the opening of the door needs to be perforated.

There is an irregular cutting face.
