Are aluminum alloy door and window covers fixed firmly by foam caulk?

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.

Are aluminum alloy door and window covers fixed firmly by foam caulk? First of all, I give a personal opinion, that is, aluminum alloy door and window covers, if all of them are fixed with foaming fillers, I think it is not firm. Why is it not firm to use foam filling to fix aluminum alloy door and window covers?

In fact, this mainly depends on two aspects: one is the characteristics of the foaming caulk, and the other is the characteristics of aluminum alloy door and window profiles. Let's answer this question from these two aspects.

The characteristics of the foaming caulk determine the characteristics of the so-called foaming filler, which is a characteristic formed after the foaming caulk is filled into the aluminum alloy doors and windows, and this characteristic determines the effect it can achieve. From this point of view, the foaming caulk cannot fix the aluminum alloy door and window covers. Specifically, 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 the aluminum alloy door sleeve and the wall are almost sealed. 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.

Second, the characteristics of aluminum alloy door and window sets are determined by the characteristics of the so-called aluminum alloy door and window sets, which are the characteristics of the aluminum alloy door and window sets themselves 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, the cross-sectional size of the profile is not particularly large. 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.

Aluminum alloy doors and windows are not all strong by foam caulk. There are other caulks.

It's very strong, this substance is specifically designed to fill the gaps, and there is nothing better to replace it, and when it dries, it is very hard, very strong.

Foam caulk is also called foam glue, styrofoam. Lightweight items, thin items have strong adhesion and firm sticking. However, heavy things, with a relatively hard texture, are definitely not realistic to fix with only styrofoam, and they are also unstable and firm. It needs to be fixed with an expansion plug.

Everyone will find that there will be a lot of hairpin glue in the installation process. The function of the blowing agent is actually to seal the gap between the window frame and the wall. But many friends will find outEspecially balconies, so as to improve the safety factor and aesthetics, but the firmness of aluminum alloy doors and windows is very important, because it determines the anti-theft and anti-falling; Then the problem is, if you see that the door and window installer only uses foam caulk (also known as styrofoam) to fix aluminum alloy doors and windows, you can let the master go directly, and tell the person in charge of door and window processing that doors and windows are related to safety, if you can't do it, don't do it.

Foam caulk is also called foam glue, styrofoam. Its primary function is to be used for caulking, because there are gaps between doors and windows and cement walls, after the foam glue is applied, the glue begins to be soft and sticky, and slowly solidifies over time, the air conditioning installer fixes the safety rope on the aluminum alloy window frame, climbs to the outside to work, and as a result, even the person fell down with the window and died on the spot. In the end, it was found that the aluminum alloy windows were not fixed at all, and the foam caulk "can be used for temporary fixing and caulking.

Long-term fixation, expansion bolts, foam caulk", can be used for temporary fixation, caulking. For long-term fixation, expansion plugs or cement are required.

It is firm, because the foam filler is certainly safe, quite strong, can effectively prevent wind, and fix the gaps between doors and windows.

Using foam caulk all is not particularly strong. Additional adhesives should be added.

Not firm. The blowing agent is mainly used to fill the gaps between objects, mainly to fill the gaps, and cannot be used as a complete reinforcement.

1.For the installation of aluminum alloy doors and windows, or the installation of broken bridge aluminum doors and windows, everyone will find that a large amount of shrinkage glue will be used in the installation process. The blowing agent actually seals the gap between the window frame and the wall.

However, many friends will find that the installation of this kind of window is only made of styrofoam, and there are no relevant fixing measures. Is that okay? Is such a window securely installed?

2.The fundamental reason here is that we are not allowed to fix aluminum alloy door and window covers with styrofoam. The most fundamental reason is that styrofoam does not have a connection function.

As for styrofoam, everyone knows that after filling the gaps, it can expand on its own, thus fixing the window. But its most important role is to seal the gap. There is no good pull.

Under the influence of external forces, styrofoam may separate from walls or window frames. Therefore, it is not allowed to directly fix the door and window frames with styrofoam.

3.According to the installation location, size and elevation of the window in the design drawing, measure the edge line of the window to both sides according to the center line of the window. If it is a multi-storey or high-rise building, the window edge on the top floor shall prevail, and the window edge shall be led down with a line pendant or theodolite, and the lines shall be drawn at the windows of each floor, and the edges of individual non-straight mouths shall be chiseled.

The horizontal position of the window is subject to the +50cm horizontal line of the floor room, and the elevation of the lower skin of the window is measured upward, and the elastic line is straight. Temporary fixation of aluminum alloy door and window frames. Before the aluminum alloy door and window frame is fixed, the hole should be squared first, so as to avoid cracks after the door and window frame is fixed, resulting in post-processing.

4.After the opening is treated, the two of us have to fix the door and window frame into our opening, that is, to ensure that there is a gap of about 5 mm on the door side of the window frame. It is common to use wooden dice to fix the window frame to the opening.

Like the four or four frames of aluminum alloy door and window frames, two frames are inserted in each frame, and some frames are fixed in this way. It is generally required to fill all the gaps with styrofoam. Styrofoam should protrude slightly.

In fact, the formal requirement is to press the excess styrofoam into the gap in a timely manner after the styrofoam has run out. Avoid cutting with a wallpaper knife. Then the whole styrofoam is done.

Robustness is guaranteed. It is because this kind of door and window cover is very strong, the hardness is also very strong, and some caulk is also used to fix, so it is very strong.

Aluminum alloy door and window covers are all fixed by foam caulk?

It is not recommended to use foam glue to fill, it is recommended to use a special kind of white glue or black glue to fill. It will be firm in a short time, but if it is long term, the foam is easy to crack and loosen, so the foam is not very fixed and will not be firm. Because foam caulk has no fixing effect, it does not have a reinforcing effect.

There is no guarantee. Because foam caulk is very unsafe, sometimes it can easily collapse, and the consequences are serious.

His firmness is relatively safe, because the foam can be self-inflated, and then effectively fix the gap in the window, and the firmness is still guaranteed to a certain extent.

In the rearrangement of the space, it is necessary to open the door opening, resulting in irregular cutting surfaces, so it is convenient to use foam filling without polluting the wall. Many suit doors are custom-made, and the width of the hole will be 1-2 cm, so as not to fit the door too big to fit in, because there is little processing on site, which will make the door cover have gaps, so it needs to be plugged with foam filling. Foam filler is an elastic material, which can cater to the thermal expansion and contraction of the door, has better adhesion than cement, and has the characteristics of fast construction and environmental protection.

The fixing effect of the foam filling is no problem for wooden doors. If it is a heavy-duty door, you need to fix the door cover and wall firmly with screws, and then fill it with foam filling, which has the function of bonding and sealing, it is difficult to buckle off, and there is basically no need to worry about falling off.

In the relevant industry regulations, in addition to the requirements of the outer door of the security door, there is no strict specification for the inner door, so that the size of the door is different. Merchants generally have to come to the door to measure the scale in advance. If there is a mistake and the measurement is not accurate, it is likely that the door they bought will not be tightly connected to the door opening, resulting in too large a gap and it will be difficult to hold it securely even with foam filling.

In the case of accurate measurement of the door frame, the gap size is appropriate when the door is purchased and installed. However, when the door is installed, incorrect operation occurs. It is conceivable that too large gaps will also appear, making the door easy to loosen, *** is white, but it will generally turn yellow, and the inferior foam filling will shrink later, resulting in cracking and loose doors.

Insufficient use of foam padding is also a common occurrence that causes the doors to loosen. In addition to the edge of the door cover, the interior is also filled. The specific steps are to retreat from the inside to the outside, then remove the outer support, cure in about 10 minutes, scrape off the excess material after an hour, and finally install the door.

Are aluminum alloy door and window covers fixed firmly with foam caulk? First of all, I have a personal opinion: if all aluminum alloy door and window covers are fixed with foam filling, I don't think it is firm.

Why is the aluminum alloy door and window cover not fixed with foam filling? In fact, it mainly depends on two aspects: one is the characteristics of the foam sealant, and the other is the characteristics of the aluminum alloy door and window profiles.

The following miscellaneous conversations at home will answer this question from these two aspects. The characteristics of the so-called foam filler are the characteristics formed after filling the foam filler in the aluminum alloy doors and windows, which determines the effect it can achieve. From this point of view, foam caulk cannot fix aluminum alloy door and window covers.

What blowing agents can achieve is to fill the gap. That is to say, after filling the foaming agent between the aluminum alloy door and window cover and the reserved hole, the entire gap can be filled with foaming agent. Then the aluminum alloy door cover and wall are almost sealed.

Therefore, it can simply fix the aluminum alloy door and window cover, but it cannot guarantee the firmness of the aluminum alloy door and window cover. The characteristic of the blowing agent filling is that although the gap is filled, the adhesion between the blowing agent and the wall and the aluminum alloy door boring sleeve cannot be guaranteed. That is to say, our aluminum alloy door and window covers are easy to separate between the openings of the wall after shaking.

This will also cause our aluminum alloy doors and windows to loosen. If there is noise, it may fall.

OK. Because I specialize in installing doors and windows, when there are gaps, they are usually filled with foam.

Yes. Some gaps will be more solid when filled with foaming agent, and will not cause air leakage, which is more practical.

Foam filling is able to keep warm, because foam filling is styrofoam, and styrofoam has good heat retention.

Speaking of caulking after installing doors and windows, I think of the set door, which is the most used bedroom door method in home decoration for more than ten years. Because the production process of the set door is based on the factory assembly line operation, its cost is very low. Everyone's life is so fast-paced, of course, I like the simple installation of the set door; Eliminating the need to purchase materials.

Will the suit door installed with foam filler loosen after a long time?

In general, the set door can be divided into a number of different installation methods, of course, polyurethane blowing agent is certainly an indispensable auxiliary material. As far as the subject asks, if the door is installed, the fixing method of the door sleeve will only use polyurethane foaming agent, without the help of other auxiliary facilities; This door cover will come off after a few years.

[1] Polyurethane foaming agent fixing method

The use of polyurethane foaming agent to fill between the wall and the gap is one of the necessary processes for the installation of the set door, because the polyurethane foaming agent fills the gap between the door sleeve and the wall densely, and the sound insulation function of the suit door can be reflected, but the larger the gap; If you don't add other fixing methods, the risk of loosening after moving in will be greater.

Step 1, assemble the door cover: after accurately measuring the size of the empty door opening, unpack the door sleeve, assemble the door sleeve on the ground and put it in the empty door opening according to the height of the door opening and the size of the door leaf. While using three wooden strips to make the upper, middle and lower supports, the infrared level is used to find out the verticality of the door cover.

Once the verticality on both sides is calibrated, a polyurethane blowing agent is used to fill the gap.

Step 2, hang the door leaf: the installation of the door sleeve is basically a one-time installation of several, that is, ordinary families, there will be three bedrooms. So, all the door casings are installed; The door leaf can be installed from the very first door casing.

Step 3, install the door sleeve line: the door has been hung up, and then clean up the excess polyurethane foaming agent in the gap between the door sleeve and the wall. Finally, install the edge line of the door cover, make an adjustment to the gap of the door leaf, and install the lock and door sucker.

Summary: This method does more harm than good, first of all, the whole process does not use a single nail to reinforce the door sleeve。There will be no problem at the beginning of use, and the force generated by the closing of the door leaf and the impact of the door sleeve will cause cracks in the joint position of the door sleeve and the wall; Until the entire door sleeve falls off.
