Replacing windows once costs more than 10,000? To say that windows are the main material with the deepest water, I guess no one disagrees.?
Windows in the decoration is a not too hot topic, it is the style of picking and choosing just a few, there is not much room for manoeuvre. But it's not until you use them that you'll feel the impact they have on your life.
Why can't my windows keep out the road noise? Why does it still leak in the summer and in the winter when the windows are closed? Here is a detailed analysis of your home window problem book.?
Lazy people can directly drag to the end to see the conclusion yo!
Why can't you isolate road noise?
If there is a road outside the window, the main sources of noise are roughly the sound of honking horns, the sound of tires rubbing against the ground, and the sound of a car's engine and exhaust pipe running.?If the window is in a neighborhood, possible noises are the loud music of a square dancer, the sound of small children playing, dogs barking, or school announcements.?
Sounds in the neighborhood and honking on the road are high-frequency noises that are easy to block out, and road noise is the low-frequency noise you can't hide from?
It is the first time for the▕ to buy a ▏ house with a good choice.
There are two factors affecting the noise level: obstruction and distance.
The more the shelter and the farther the distance from the source of noise, the less the amount of noise.
Studies have shown that the noise level is highest in the middle floors of buildings close to the street and decreases gradually to the top and bottom floors.
In neighborhoods surrounded by buildings that are shaded, the top floors are the noisiest, and the noise level decreases from top to bottom because the higher the floor, the less the shade, and the louder the noise level.?
Knowing this, you can pick the right floor based on the distance from the noise source, the number of buildings around you, and the amount of greenery (which also counts as shade) you have to cover.
Buildings close to the road have the loudest noise on the middle floors.?▏What kind of glass is good for soundproofing? ▕？
Long-term exposure to low-frequency noise can make children's hearing insensitive.?In order to achieve the effect of soundproofing, we have to cut off the medium of sound transmission, which is called "sound bridge" in the construction of acoustic environment.
With the window seal intact, the air medium in the window and the metal medium contained in the window can still help the sound propagate.
In that case, wouldn't vacuum glass be the best choice??After the air is removed from the vacuum glass, in order to prevent the two pieces of glass from being forced together by atmospheric pressure, the two layers of glass are fitted with a metal support between them to carry the pressure of atmospheric pressure, and some inert gas is injected in between.?
Without air, sound can still travel through the metal support.?
Additionally, the vacuum glass on the production process requirements are extremely high, the process is not pass, after two or three years will leak into the air, slowly become hollow glass.
Insulating glass is actually a kind of insulating glass, the original production process is in the middle of the two layers of glass to extract all the air, injected with inert gas, and then the overall sealant.
But many manufacturers in order to reduce costs, the previous steps omitted, only two layers of glass, the middle is air.?
Insulating glass is very popular because of good thermal insulation, and sometimes as "acoustic glass" to sell.
However, insulating glass and vacuum glass can only block high-frequency noise, and can't do anything about low-frequency noise.
Currently on the market can be bought to shield high and low frequency noise in the acoustic glass, is laminated glass.
The PVB film in the middle of laminated glass can effectively filter low-frequency noise, and according to different usage environments, there are double and triple layers.?
Three-pane laminated glass can be used if the floor is high, there is no blocking building around, and there is an airport or train station nearby.
Lower floors, surrounded by covered buildings, near the intersection can use double laminated glass.

Besides glass, we also talk about the profile (window frame).?The soundproofing effect of broken-bridge aluminum windows and doors is not as good as that of plastic-steel doors and windows, that is because the metal content of broken-bridge aluminum is much higher than that of plastic-steel.?
The same thickness, plastic steel doors and windows sound insulation effect is stronger than the broken bridge aluminum 5-15 dB.?
Additionally, high-quality plastic steel windows are internal thick-walled multi-cavity, sound propagation in the multi-cavity body reflected back and forth many times after a portion of the consumption, sound insulation effect is therefore greatly enhanced.

From the way of opening, the smooth push needs gaps and space, so the sliding doors and windows can not guarantee the airtightness of its sound insulation and heat preservation effect is not compared with the casement type.
Reinstall the sealing strip that is needed for all soundproof glass, you will find the window is getting harder to push open.?
Scenarios for sealing strips ? Image Source:BazaarGadgets.com?Insulation and moisture resistance, choose broken bridge aluminum is better?
Your windows are drafty and not insulated? Rainy days will leak? This is all because the windows are not well sealed.?It may be because the home with a sliding window rather than casement windows, the quality of the window itself is not good, the installation of styrofoam sealant waterproofing glue did not play enough to lead to the window frame and the wall between the left a small gap and so on?
Especially in the south where there is no heating, the thermal insulation and moisture-proof performance of the window is even more important!
Inverted broken bridge aluminum alloy windows Figure Source: lqdongxing.com?Broken bridge aluminum alloy windows and doors combine the advantages of aluminum alloy and plastic two materials, heat preservation, fire prevention, waterproofing, anti-theft, very popular in the market.?
It should be noted that the current manufacturers selling windows is more like an integrator, aluminum (window frame) from Feng aluminum or Zhongwang such a professional production plant to buy, hardware from a variety of Chinese and foreign joint venture manufacturers there to take goods ...... a variety of channels to buy good parts assembled into windows to sell.? Live Faner offers broken bridge aluminum alloy windows?Break the bridge aluminum windows do not have more well-known manufacturers, the entire industry is still in a mixed stage, a variety of quality problems are also endless.?
For example, the national standard stipulates that the aluminum thickness of the broken bridge aluminum windows and doors ≥ 1.4mm, the insulation bar should use PA66 nylon.
Some manufacturers in order to save costs, the thickness of aluminum only 1.3mm, the use of cheaper PVC plastic insulation strip.
Inferior insulation strip tensile strength is poor, the thermal expansion and contraction ratio does not match the aluminum, with the use of the use of the shed.?
Fortunately, PVC has flammable properties, and can be identified by using a lighter to start a fire.
The middle black insulation strip is PA666 nylon Source: tao.co?m
The normal service life of the hardware should be about 10-15 years, some of the next few years with a few years on the bad, resulting in the scrapping of the whole window.
There are also manufacturers take inferior aluminum to substandard, the use of which is susceptible to the impact of inclement weather, resulting in aluminum deformation, and even cause the consequences of glass rupture and fall off.?
In addition to the naked eye can see that inferior aluminum is not so shiny, lighters to identify the thermal bar, the other identification criteria for consumers is really too high.?
Given the market's continued lack of brand assurance and industry regulation, the safest buying advice we can give is to shop in large building materials markets.
How do you avoid the pit of windows?
Buying windows is generally divided into two kinds of offers, the first xx yuan / square meter is the offer of aluminum + glass, the second yy yuan / square meter is the offer of aluminum + glass + hardware + screens.?Some manufacturers will give the price of the whole package, including what does not contain what is listed clearly, but this dry and sharp manufacturers are relatively few, we still count the number of buy windows will step on the pit it!
▏Measurement of the heart of the financier?
Window production is depleted, for example, your home to use 5.4m of aluminum, the remaining 0.6m is wasted.?
That's why some manufacturers will count 5.1m2 of glass as 6m2 and 5.4m of aluminum as 6m.?
But the production technology is better, can control the loss of manufacturers will give you a loss ratio, from 1.1-1,5 ranging from the total area / total length multiplied by the loss ratio after rounding down to the final billing area.
What is the financial cost of ▏windows?
The financing of the financing of the ▏windows is the same as the financing of the financing of the financing of the ▏department of finance.
But this does not mean that all the additions are malicious additions, windows are a non-standard product, the final price will be based on the actual situation of your home.
If you have a U-shaped window with two corners, you'll have to pay for two more risers, and if your window opening is too high, you'll have to pay for the load-bearing transom (the horizontal riser) ......?
Or maybe you only have one window, and you can't meet the requirement of "x square meters", then the business may not be able to give you free shipping and free installation fee.
Generally, manufacturers have a standard of only one window in y square meters, so if you want to open more windows, there will be additions.
The yellow box is the column?
But there are some additions that you should be careful about.
For example, when installing windows, filling the gap between the wall and the window frame requires a lot of styrofoam and sealant, and in order to prevent rain and waterproofing, both inside and outside of the window have to be smeared with waterproofing adhesive, and the more of this adhesive, the better the window's various properties.
But the cost of gluing will not be reflected in the offer, some manufacturers to the time to be installed before you want to glue the money.
Because of the high volume, it is possible to overcharge you by a few hundred to a few thousand.?
The best way is to sign a contract with the manufacturer to determine what glue with what brand, and the cost of glue to the cost per square meter.
Other additions may include, but are not limited to: sealing strips, Low-E film, corner yards, corner grouping adhesive, etc.?
▏Air protection measures for the▕?
Unless your home is on the first floor, make sure to ask your workers to bring safety belts for working at height, and it is best to put this requirement on the contract.
Otherwise, in case of an accident, you are the first responsible person and need to bear a large amount of compensation costs.
Finally, a simple and brutal summary: ?
Acoustic windows are recommended for plasticized steel windows + multi-layer PVB laminated glass.?
The focus on thermal insulation recommended broken bridge aluminum alloy windows + insulating glass.?
If your home is surrounded by residential buildings, not on the side of the road or viaduct, there is no low-frequency noise, broken-bridge aluminum windows and doors are enough.?
If your home is on the side of the road, or is the middle floor, low-frequency noise can not be blocked, quickly consider changing the plastic + PVB laminated glass doors and windows.
No matter what window you buy, in the local large building materials market to buy more secure Oh!
