home window sound insulation is not good how to do?

The improvement of living standards, traffic is more and more developed, coupled with the square dance in full swing. Many people inevitably live on the side of the road, and then the problem comes. Although the traffic is convenient, but a lot of noise harassment. In particular, many elderly people, as well as children, will have all kinds of discomfort. Noise invasion, irregular daily life, a large reason is because the window sound insulation is not good. What if the window sound insulation is not good? Let's take a look at these tips. Option 1: If the window sill at home is not wide enough, or if the ventilation performance is not good enough after adding a layer of sound insulation window, there is another way to remove the original window and convert it into a layer of low-frequency sound insulation window. Option 2: Sticking the window sound insulation film The sound insulation film is recently popular. It is a multi-layer structure, and the sound insulation resin is sandwiched by a polyvinyl butyral (PVB) layer. The entire intermediate sound insulating film is uniformly distributed among fine particles having a heat insulating effect (heat insulating fine particles). When using sound insulation films in buildings, the high-performance intermediate film sandwiched between the films has visible light transmission properties, so it does not block the visible light transmission of the building and can maintain a clear line of sight. What is more noteworthy is that the window sound insulation film is cheaper, and the usage is relatively the same as that of the mobile phone film. Option 3: Install soundproof curtains. The soundproof curtain is a kind of curtain box installed on the top of the inner frame beam installed in the window. In some closed places like cinemas, there will be more soundproof curtains, and the effect is also good. Option 4: Install the window sound insulation sealing strip. As the name implies, the sound insulation sealing strip is only effective for windows with poor sealing, and the price is low. However, it needs to be determined whether the lack of sound insulation is caused by the large gap in the window, or it is useless to paste it. The sealing strip is to block the gap of the window, which is almost the same as the sound insulation cotton. Option 5: Add a layer of sound insulation window Sound insulation window is generally composed of double or three layers of the same quality products or different thickness of glass, and the window frame is connected, which will be thicker than ordinary window glass. Some sound insulation windows use specially processed sound insulation layers or aluminum alloy frames filled with desiccant between the sound insulation layers to isolate the noise of each frequency band to the greatest extent. But the price of this ventilation device is higher. In addition, it is best to agree with the merchant in the contract to achieve the sound insulation effect after installing the sound insulation window to prevent bad merchants. If you want to reduce the noise impact in the most cost-effective and economical way, one way is to consider sticking a sound insulation film on the glass first, and then sticking a sealing strip on the window gap. After that, if conditions permit, change the curtains with good sound insulation effect. This operation is simple and easy, the price is low and affordable.

This is the heart of a door and window. The quality of the hardware accessories is directly related to the service life of the door and window, and the overall quality! The method is as follows: 1, different materials of clean stainless steel handle and other stainless steel material "hardware" can be used to clean agent to wipe, can increase the brightness, but other materials of accessories and locks can not be used with corrosive detergent to wipe, so be sure to understand the material of the product hardware before buying. 2, keep good sliding doors and windows hanging wheels and casters and other accessories in the long-term activity process, there may be dust or particles stuck on it, and reduce the sliding performance, we should put the dust inside the slide often clean up. If necessary, you can drop one or two drops of lubricating oil every six months to a year. 3. Opening of the lock When using the product, we should pay attention to the direction and amplitude of the rotation and stretching of the lock handle. Do not open it with continued force, and children should not swing on the handle of the door lock. This is very prone to danger, and it also causes damage to the door. Once the lock is broken, the house is basically like undefended, and the potential safety hazard is very large. 4 Maintenance of lock cylinder If your lock cylinder is not flexible enough, you can scrape a small amount of black powder from the pencil core and gently blow it into the lock hole. This is because the graphite component is a good solid lubricant. Do not drip into the lubricating oil, because it will be more likely to adhere to dust, resulting in unlocking obstacles.

Winter doors and windows sealed with knowledge, four matters needing attention to know!

In winter, the northern cold areas generally like to seal doors and windows, because it will be warmer, but we often find that the sealing of doors and windows in winter is not very good, so what aspects should be paid attention to in the sealing of doors and windows in winter? The following Xiao Kai will introduce the following four points for attention: the main reason for uneven door and window profiles and air leakage lies in the tightness between the door and window sash and the frame, and the flatness of the profiles is an important factor affecting the tightness. If the flatness of the profile is not enough or deformation, there will be a certain gap between the door and window sash and the frame, resulting in air leakage. The quality of the sealing strip is defective or aging sealing strip is the key to the sealing of doors and windows, and the quality of the sealing strip on the market is very different. The high-quality sealing strip has strong toughness, strong wear resistance, and is not easy to break; while the poor quality sealing strip is very fragile, easy to corrode and break, and cannot achieve the sealing effect. If the sealing strip is not installed well, uneven or bulging may lead to air leakage. There are cracks between the frame and the wall. During the installation of doors and windows, many winter door and window sealing workers did not do a good job of sealing the door frame, window frame and wall due to hasty work or jerry-building. Especially in the old house, the wall is loose in the settlement process, and the tight degree between the door and window frame is reduced. If the waterproof glue is not evenly coated, the sealant is not fully done, or the expansion bolt is not nailed firmly, it will make it impossible to "fit perfectly" between the frame and the wall ". In the summer rain weather is easy to collapse glue, autumn and winter season is caused by air leakage. Hardware lock is not strong door and window hardware quality is also closely related to the sealing performance. Especially the casement window, it relies on the hardware of the transmission to seal, if the transmission quality is not good, it is easy to leak from the edge of the window sash. At present, the door and window hardware sold on the market is divided into domestic and imported. Domestic hardware generally has two locking points, while imported hardware usually has three locking points. The principle is that when the doors and windows are locked, the lock points and lock seats are firmly buckled together, and cooperate with the hinge or sliding support to generate strong sealing pressure and elastically deform the sealing strip, thereby providing sufficient sealing performance for the doors and windows. Therefore, the lock is not strong hardware, will make the doors and windows of the sealing performance is greatly reduced. The above is the four precautions for sealing doors and windows in winter introduced by Xiao Kai. If you find that the doors and windows in your home are not well sealed in winter, you can check them from these four aspects!

Leakage of doors and windows to solve the strategy collection

Outside the window is the contact indoor and outdoor window, its role is extraordinary. But also because of their existence, will be due to various reasons for leakage caused by indoor wall moldy black, affecting the living environment and home life, to bring a lot of trouble and inconvenience to friends. To solve the problem of leaking windows, Xiaobian thinks that we should first find out the cause and then prescribe the right medicine. Raiders 1: Keep your eyes open and find out the reason for the leakage of windows. In rainy days, the leakage of windows has become a problem that worries many people. The reasons for the leakage of windows are different, and the solutions are also different. Therefore, first of all, it is necessary to carefully find out the cause of the water leakage before taking targeted measures to rescue the window from the fire and water. 1, the window loose deformation caused by leakage between the window and the frame of the loose caused by the leakage is the most common reason. On the one hand, when the door is closed, the window will also produce resonant vibration. As time goes by, the gap between the window and the wall is getting bigger and bigger. On the other hand, the window with poor quality is not strong enough and is easy to deform. The mortar layer on the window frame will crack and fall off soon after use, thus causing leakage. 2. Irregular installation of windows causes water leakage. Window lintels and windowsills did not make drip tanks and water gradient during window installation. The outdoor windowsill is higher than the indoor windowsill plate, and the windowsill plate plastering layer does not make defects such as downstream slope or slope inward and windowsill plate cracking, resulting in water leakage. 3. Poor drainage of window slot drainage holes causes water leakage. Some windows may not have drainage holes, especially sliding windows. Rainwater accumulates in the sliding frame groove and cannot be drained out. When it is full, it seeps into the house. Or when the outer window sill is tiled, the drainage hole is blocked, and the rainwater in the sliding frame groove seeps into the wall, causing water leakage. In addition, it has been used for a long time, drainage holes may be blocked by stolen goods, resulting in water flow can not be discharged in time. 4. Damage to the waterproof layer of the wall near the window causes water leakage in the old house with a long age. Damage to the waterproof layer of the wall around the window is prone to water leakage. In addition, when the old house is renovated and replaced with windows, unprofessional window removal will cause damage to the waterproof layer of the outer wall. If it is not repaired in time, water leakage is likely to occur after the new windows are installed. Raiders two: suit the remedy to the case of the window leakage solution in front of the understanding of the window leakage of several important reasons, so for these reasons, for the window leakage, the following measures can be carried out to repair. 1, strictly close the material quality window itself quality problems caused by water leakage, you need to directly repair or replace the window. The quality of the purchased window frames, window sashes, sealing strips, etc. must pass. At the same time, the waterproof sealing materials used should have material quality certification documents to ensure that the material quality meets the requirements. Do not choose inferior sealing materials. 2. Reseal the gap. If the gap between the window frame and the wall and the window sill causes water leakage, reseal the gap. For the gap between the outside window frame and the wall window sill, it is best to remove the original seal and fill in the weather-resistant glass glue to seal; For the gap between the outside window frame and the window sill, it is best to remove the original seal, fill in the weather-resistant glass glue to seal, and then seal with mud and sand slurry to make waterproof. 3, the correct installation of the window outdoor window sill should be lower than the indoor window sill plate 20mm is appropriate, and set down the water slope, rainwater drainage smooth. The gap between the outer frame of the metal window and the indoor window sill must be closed with weather-resistant high-elasticity sealant to ensure water tightness and prevent leakage. Window lintels, window sills should be made enough drip gutters and water slope. 4. Keep the window drainage channel unblocked. For the leakage caused by the blockage of the window frame drainage channel, the problem can be solved by keeping the drainage channel unblocked. If there is a problem with the location of the drainage hole, it is necessary to close the original hole and reopen the hole. 5. Redo the waterproof layer of the window wall. The window wall itself leaks. The solution is to knock on the outer wall, repair it, and check whether it is firm after repair. Remember to lay a waterproof layer. Strategy 3: Eliminate hidden dangers of water leakage and pay attention to window maintenance. Friends who are used to heavy rain outside the house and suffering from light rain inside the house must be interested in window maintenance. The following is a few window maintenance and inspection knowledge, please have a look. 1. Check the connection parts of the window frame. Check the connection parts of the window frame frequently, tighten the bolts in time, and replace the damaged parts. Locate the vulnerable parts such as axle pin, wind brace and floor spring, check them frequently, and add lubricating oil regularly to keep them clean and flexible. 2. Check the junction of the window frame and the wall. Check the junction of the window frame and the wall frequently. If it is loose over time, it is easy to deform the frame as a whole, making the window unable to close and seal. Therefore, the loosening of the screws at the connection should be tightened immediately. 3, daily use of windows must be standardized in use, the action should be as light as possible to open and close, do not use too much force too hard; When the window is opened, if there is any obstacle, the fault should be eliminated first. High-grade doors and windows such as inward tilting windows and folding doors and windows shall be operated in strict accordance with the instructions. 4, the window needs to be cleaned and maintained frequently to prevent its leakage and prolong its service life. Daily needs to be cleaned frequently to keep the surface of the window clean. When scrubbing, try to choose soft gauze or cotton silk to avoid scratching the surface of the doors and windows. In the case of stains and dirt, available water, alcohol or neutral detergent, cleaning. 5. Pay special attention to maintenance after rainy days. After rainy days, wet glass and door and window frames should be wiped dry in time, and special attention should be paid to wiping the water in the chute. The chute is used for a long time, and the friction force increases. You can add a little oil or apply a layer of fire wax oil.

Door and window design standards, you know?

Doors and windows are the most basic configuration of general housing, and they are also the most important factors affecting lighting, ventilation and comfort. The window sill height in general residential buildings, the requirements of the window sill height is not less than 0.9m, when the window sill height is less than 0.8m, protective measures should be taken. In public buildings, the height of the window sill varies from 1.0 to 1.8m, and the height of the bottom surface of the window sash opening to the public walkway should not be less than 2.0m. In general residential buildings, the height of the window is 1.5m, plus the height of the window sill is 0.9m, the top of the window is 2.4m from the floor surface. The height of the window should be determined according to the requirements of lighting, ventilation, space image, etc., but pay attention to the excessive rigidity of the window, and if necessary, add a beam or "frame". In public buildings, the height of the whole piece of glass has exceeded 7.2m, which is no longer within the scope of general windows. Window width window width generally starts from 0.6m, according to the provisions of the building standard hole specification, the width modulus of the general building hole is 300mm, that is, the general width is 600mm, 900mm, 1200mm, 1500mm, and so on. It should be noted that when the window is too wide, a vertical keel or "splicing" should be added, otherwise the stiffness of the window is prone to problems. The height of the door for people to pass through the door, the height is generally not less than 2m, no matter how high it is, it should not exceed 2.4m, otherwise there will be a sense of emptiness, and the door leaf production needs to be specially strengthened. Such as modeling, ventilation, lighting needs, can be added on the door waist window, its height from 0.4m, but not too high. The door for vehicles or equipment to pass through shall be determined according to the specific situation, and its height should be 0.3~0.5m higher than that of vehicles or equipment, so as to avoid collision with the door frame when vehicles are bumped or equipment needs to be carried by rollers. As for the clearance requirements for all types of vehicles, consult the corresponding specifications. If it is a large-volume and large-space building such as a stadium or an exhibition hall, when a super-scale door is needed, an additional door of conventional size can be added to the gate fan so that people can pass through when the door does not need to be opened. At present, there are many inspection doors for various equipment tube wells in the building, which are not places that often pass through, so the upper frame is generally the same as or lower than the ordinary door, and there is a threshold at the same height as the skirting line at the bottom, so its net height does not need to be rigidly limited to 2m and 1.5m. Hotel room, clear height of door opening ≥ 2.1m. The width of the door is generally 0.9~1m for residential separate doors, 0.8~0.9m for separate rooms, 0.8m for kitchen doors and 0.7~0.8m for toilet doors. due to the moving in of modern furniture, the upper limit size is now adopted. The door width of public buildings is generally 1m for a single door and 1.2~1.8m for a double door. If the door width is further wider, the production of the door leaf should be considered. The width of the door leaf for a double door or multiple doors should be 0.6~1.0m. The width of the hotel room door opening is generally ≥ 0.9m, and the width of the bathroom door opening is ≥ 0.75m. The width of the exit door for safe evacuation shall be set according to the calculation and specifications (relevant fire protection specifications). The width of the maintenance door of the pipeline well is generally 0.6m. For motor vehicles or equipment through the door, in addition to its own width, each side is only set aside 0.3~0.5m gap. Doors and windows maintenance should regularly clean the dust on the doors and windows, keep the doors and windows and glass, hardware clean and bright. If the doors and windows are contaminated with oil stains and other things that are difficult to clean, it is best not to use strong acid or alkali solution for cleaning, otherwise it is not only easy to damage the surface finish of the profile, but also damage the protective film and oxide layer on the surface of the hardware and cause corrosion of the hardware. When opening doors and windows, the intensity should be moderate, try to keep the opening and closing speed uniform. Try to avoid hitting doors and windows with hard objects or scratching the surface of the profile. The granular and other sundries on the inner side of the frame should be cleaned in time to avoid blocking the drainage channel and causing poor drainage and water leakage. When it is found that the doors and windows are not flexible to open or other abnormal conditions during use, the cause should be found in time. If the customer cannot eliminate the fault, contact the door and window manufacturer and supplier so that the fault can be eliminated in time.

The purchase of screen window should pay attention to matters

Autumn mosquito, fierce as a tiger! People are thinking about how to repel mosquitoes. We can see that major office buildings, supermarkets and park areas are using insecticides and mosquito coils to prevent mosquitoes. The residential area should be based on environmental protection and health as the premise, to a greater extent, the use of new products to prevent mosquitoes, improve indoor air quality and living comfort! The screen window gives you plenty of fresh air and effectively blocks the invasion of mosquitoes. Of course, you can also regard it as a scene of home life. Now there are more and more screens on the market, so how to choose a cost-effective screen? The following Kermit Aluminum will simply share with you three precautions for screens. 1. screen screen screen is good or bad, the first is the screen. There are domestic and imported yarn. Most of the imports are made of chemical fiber; the domestic ones are glass fiber, and some are made of plastic. Imported high-quality fiber window screens can be pushed and pulled tens of thousands of times without deformation; domestic glass fiber can only withstand thousands of times; and plastic window screens because of the relationship between the material, easy to thermal expansion and contraction, the probability of deformation is large. Therefore, we should choose the imported fiber window screen. 2. frame material high-quality screen window frame multi-choice plastic spray or electrophoresis aluminum alloy special profiles, color variety. The quality of the frame depends on its thickness. The thickness of the high-quality frame profile should be above 1mm. At present, most of the popular ones in the market are 0.8mm, 0.6mm and even 0.5mm. The thickness of the frame is also a factor in determining the price. 3. accessories 1, bearing. Because the bearing directly affects the use of the screen window. At present, the low-cost screens on the market are used in domestic bearings. Most of the domestic bearings are open bearings, if they enter the dust, they will not run smoothly. 2. Spring. Ordinary spring use after a period of time will find that the spring elasticity decreased, the gauze back to the yarn box. It is recommended that consumers should buy imported fully enclosed silent bearings and special springs.

What are the materials of the balcony? (1) ordinary aluminum alloy window: (advantages) it has good weather resistance and anti-aging ability. (Disadvantages) The heat insulation is not as good as other materials, and the sealing and heat preservation performance is not very good. (2) frameless window: (advantages) it has good lighting, the largest area of air convection, beautiful and easy folding. (Disadvantages) Poor heat preservation, poor sealing, and general sound insulation. (3) plastic steel window: (advantages) it has good sound insulation, heat insulation, fire resistance, air tightness, water tightness, corrosion resistance, heat preservation and so on. (Disadvantages) After all, it is a PVC plastic profile. The surface will be yellowed and the form will be deformed after a long time. The service life is 20-30 years. (4) Broken Bridge Aluminum Doors and Windows: (Advantages) Aluminum with a wall thickness of more than 1.4 is added with a heat insulation layer on all the basis; it also has good sound insulation, heat insulation, fire resistance, air tightness, water tightness, corrosion resistance, heat preservation, maintenance-free, etc.; it is a metal aluminum profile that can be used for a long time without change and color fading. (Disadvantages) The price of aluminum is expensive and the production cost is relatively high. The above four materials are the mainstream balcony sealing materials in China, of which ordinary aluminum alloy and frameless windows are mainly used in the balcony sealing in the south, while plastic-steel doors and windows and broken bridge aluminum doors and windows are mainly used in the balcony sealing in northern cities. With the prosperity of the society and the hustle and bustle of urban life, plastic-steel doors and windows and broken bridge aluminum doors and windows are gradually used in the balcony sealing operation in the vast southern cities. How long is the time limit for sealing the balcony? 1. The production cycle of ordinary white plastic steel doors and windows or broken bridge aluminum doors and windows in general factories is about 10 days, and the installation of sealing the balcony only takes 1 day. If there are special circumstances or more square meters, it takes 2 days. 2. The sealed balcony is a special-shaped balcony. It takes 15-20 days for special window shapes to be customized, or for color treatment and tempered glass treatment, and only 1-2 days for sealed balcony installation. sealed balcony what material is best? At present, the materials for sealing balconies are mainly aluminum doors and windows with broken bridges and aluminum-clad wood doors and windows, of which aluminum doors and windows with broken bridges are most widely used in family decoration, while aluminum-clad wood doors and windows are mainly used in high-end villas and hotels, and the price is also very expensive. Although aluminum doors and windows with broken bridges are the most popular doors and windows nowadays, consumers should identify the top ten brands of aluminum doors and windows and windows and windows and windows and windows with broken bridges in China, remember to choose those unknown miscellaneous brand broken bridge aluminum for cheap, often the material wall thickness is lower than the national standard. The colors of plastic steel doors and windows sealed balconies are: red teak, light walnut, red walnut, Sabri, beech, black teak, sandy black, sandy gray, brown, green, grass green, light green, white maple, medium gray, silver gray, bright red, ancient red, golden walnut A, golden walnut B, pine, all kinds of colored plastic steel doors and windows are available to make your windows more beautiful!
