How to seal doors and windows to prevent dust?

Have you noticed that even if the aluminum doors and windows of the broken bridge are closed at home, a layer of dust will fall on the indoor furniture in a few days, so this dust comes from? Have you ever suffered from the problem of "not going home for three days, and dust is flying all over the house"?

Special customized wool tops: Each door and window lap is equipped with special customized encrypted wool tops to effectively prevent dust from entering.

Adhesive strip sealing: flexible material, with a degree of relaxation, to ensure that the fan is in closer contact with the glass and increase the sealing. A rubber strip is added in the middle to seal, and the rubber strip forms a horn to prevent dust invading.

Hardware positioning, good system hardware blessing, make doors and windows tighter and safer, enhance the sealing of doors and windows.

Doors and windows are an organic combination of performance systems, which need to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sun shading, weather resistance, operation feel, etc., as well as the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose, and seals, all of which are indispensable to form high-performance doors and windows. This is an important reason why doors and windows are sealed against dust.

If it is sealed, then there will be no ventilation, no air flow, and no dust will come in.

Otherwise, there are always gaps, and there is flying dust in the air that is difficult to see with the naked eye, and it is obvious if it falls on objects.

Flat clothing can also lose fibers.

In winter, the cold areas in the north generally like to seal the doors and windows, because it will be warmer, so what aspects need to be paid attention to in the sealing of doors and windows in winter? Let's take a look with the old Lai Bulai doors and windows!

The door and window profiles are uneven.

The main reason for the air leakage of doors and windows lies in the tightness between the door and window sash and the frame, and the flatness of the profile is an important factor affecting the tightness. If the flatness of the profile is not enough or deformed, there will be a certain gap between the door and window sash and the frame, resulting in air leakage.

Defective or deteriorated seals.

Sealing strips are the key to sealing doors and windows, and the quality of sealing strips on the market varies greatly. High-quality sealing strips have strong resistance, strong wear resistance, and are not easy to crack; The poor quality sealing strip is very weak, simple corrosion, cracking, and cannot achieve the sealing effect. If the sealing strip is not installed well, it is uneven or bulging, which may lead to air leakage.

There is a crack between the frame and the wall.

In the process of door and window installation, many door and window sealers do not do a good job of sealing between door frames, window frames and walls due to rushing or cutting corners in winter. Especially in old houses, the walls loosen during the settlement process, and the tightness between them and the door and window frames is reduced. Assuming that the waterproof glue is not evenly coated, the sealant is not done enough, or the expansion bolts are not nailed firmly, it will make the frame and the wall unable to "fit tightly".

In the rainy weather in the summer, it simply collapses, and in the autumn and winter, it forms a leakage.

The hardware is not locked tightly.

The quality of door and window hardware is also closely related to the sealing function. In particular, casement windows rely on the hardware of the actuator to seal, assuming that the quality of the actuator is not good, it is easy to leak air from the edge of the sash. At present, the most advanced door and window hardware on the market is divided into domestic and imported.

The principle is that when the door and window are locked, the lock point and the lock seat are firmly buckled together, and the hinge or sliding brace is matched to produce a strong sealing pressure, so that the sealing strip is elastically deformed, and then provides the sealing function that the door and window meet. Therefore, the hardware that is not firmly locked will greatly reduce the sealing function of doors and windows.

1. Choose your favorite sealing strip online. According to the size of the gap of the window you need to seal, choose the appropriate length of sealing strip wool with the thickness of the early.

2. Prepare the tools you need. Sealing strips, rags, scissors, small brushes (discarded toothbrushes can be used for the second time, brushes that are too large are inconvenient to use.) )

3. Do the cleaning work, and use a discarded small toothbrush to brush off the floats and debris in the cracks of the windows.

4. Wipe it with a damp rag and then with a dry rag. (There is water and dust and the sealing strip cannot be adhered to, so the wet rag is too wet and needs to wait until the water is dry before attaching the sealing strip).

5. Roughly measure the length of the bottom and side of the window. Then make a mark on the seal.

6. Cut the sealing strip of the required size.

7. Then the 4 points of the window and the fast selling base are respectively stained with sealing strips. During the gluing process, he tore off the tape and rolled the sealing strip again, so that he applied it to the window frame.

What is the installation method of window seals.

1. Before installing the glass, the debris in the notch should be carefully removed, such as mortar, brick chips, wooden blocks, etc., and the glass should be carefully centered when placed to ensure that the gap on both sides is even, and it should be fixed in time to prevent collision and displacement, and deviate from the center of the notch.

2. The rubber sealing strip can not be pulled too tightly, and the blanking length is 2o-3omm longer than the assembly length. When installing, it should be embedded in place, the surface should be straight, and the glass and glass notch should be in close contact, so that the force around the glass should be uniform. At the corner, the rubber strip should be disconnected on an inclined plane, and the glue should be injected at the disconnection place to bond firmly.

3. When fixing the glass with sealant caulking, the glass should be squeezed with rubber strips or rubber blocks first, leaving a gap for glue injection, and the glue injection depth should not be less than 5mm, and the glass should be kept from vibration before the glue cures.

4. The installation part of the wool top is generally on the window (door) sash, the four periphery of the frame sash or the sealing bridge (wind shield) to enhance the sealing between the frame and the fan.

5. The specifications of wool tops are an important factor affecting the performance of sliding doors and windows and watertightness, and it is also an important factor affecting the switching force of doors and windows. If the specifications of the wool top are too large or the vertical hair is too high, it is not only difficult to assemble, but also increases the moving resistance of doors and windows, especially the initial resistance when opening and the final resistance in place when closing.

6. The specification is too small, or the height of the vertical wool strip is not enough, and it is easy to get out of the groove, which greatly reduces the sealing performance of the door and window. The tops need to be siliconized, and the appearance of the tops with qualified quality is straight, the bottom plate and vertical hair are smooth, no bending, and there are no pittings on the bottom plate, which meets the regulations.

You can put some plants on the windowsill, or you can add a layer of thin, small mesh yarn on top of the screen, so that it can be ventilated without affecting the lighting, and it can also prevent dust.

Functions of the screen:

1. When opening the window, it can prevent mosquitoes, flies and other insects from flying in and crawling in;

2. It can filter some wool and sundries that enter the room;

3. A certain function of blocking the line of sight;

4. You can decorate doors, windows, and rooms;

5. Prevent some small debris from going outdoors;

6. The screen window with a protective fence can also prevent children from falling downstairs.
