How to choose broken bridge aluminum doors and windows?
1 . Profile thickness
Profile thickness simply refers to the thickness of the window frame.
Profile thickness currently generally includes, 50 series, 60 series, 70 series, etc. , the larger the number , the thicker the window is. When you go to the door and window shop to set the window , merchants will introduce you to the thicker the window thickness. , better Sound insulation , everything is good , in theory, it is true , but the thicker the window, the more intuitive it is!
How do you choose your home? If it is quiet in the community , the window is not facing the street. , it is enough to choose 60 , if the window is facing the street , quite noisy , we recommend that you select profiles 70 or more. Don't blindly believe in the sound insulation ability of thick windows. , if it is really facing the street , no matter how thick the profile is, it cannot completely block the noise.
2 . Glass thickness
Merchants often say "5 9 5" 5 12 5" , good understanding , the first 5 is the thickness of the first layer of glass ,9 or 12 refers to the thickness of glass Hollow , the second 5 is the thickness of the second layer of glass.
Generally, "5 9 5" and "5 12 5" are enough for household use.
If you care about noise very much , you can select Triplex glass , it is better than simply increasing the thickness of the profile. (As shown in the following figure)
3 . Profile wall thickness
Usually a door and window manufacturer in the home decoration market , most of them choose products with high output rate, that is, products with relatively thin wall thickness to reduce the cost. , some small manufacturers produce 1 .2mm-1 . The 3mm thick one is lower than the national standard , however, the national standard stipulates that the thickness should be greater than or equal to 1. .4mm , the thicker the profile, the higher the cost. , better quality , if funds allow , it is recommended to buy doors and windows made of thicker materials. The wall thickness of domestic first-line famous brand broken bridge aluminum doors and windows is 1 .4MM , reach the national standard , however, the wall thickness of some unknown broken bridge aluminum doors and windows brands is only 1 .2MM , not up to the national standard , the product quality is naturally inferior.
4 . How many seals
▲ this statement is often mentioned in Broken Bridge aluminum casement window , merchants usually advertise 5, 6 or even their windows. 10 channel Seal , theoretically, the more seals , the better the heat preservation and anacoustic effect should be. However, there is no corresponding monitoring evaluation and explanation from authoritative departments. The number of seals has little impact on the price.
3. How to choose hardware
Window hardware includes handles, actuators, hinges, wind brace, etc. , the quality of hardware directly affects the opening flexibility, tightness and service life of windows. , try to choose imported products within the economic scope , even if you choose domestic products, you should also choose products of big brands.
Let's talk about wind brace separately. : wind brace is to prevent the window from being damaged when the wind blows , windows should be installed with wind brace , poor quality wind brace will make the window open and close inflexibly , wind brace should choose stainless steel material. If the window at home wants to be opened at 180 ° , consider not installing wind brace , however, attention should be paid during use.
IV. Other precautions
1 . Price
You have determined which material and thickness windows are easy to use in the store. , merchants will generally quote you a price. , for example, 500 yuan per square meter , but the actual cost is difficult to implement at this price. , because this price only includes the most basic fees , for example, there is only one window. , cheapest hardware, etc. , in actual measurement , according to the number of windows opened, the measuring personnel will , how many beams and columns are used , multiple glue , and so on , the last calculated number will be very scary. For example, your home 10 square meter window , the merchant quoted 500 yuan per square meter. , you feel it is 5000 yuan , but in the end, the total price is likely to exceed 10000. You can only imagine the multi-fee project. , I can't do it without them.
There is a little bit of pit , almost all merchants have such a rule : small window area , less than 2 square meters calculated by 2 square meters , in this way, for example, the small window of the bathroom , dare to ask you 1000 yuan!
There is another algorithm , as shown in the following figure , none of these right-angle Windows has a small area. , less than 2 square meters separately , it must be calculated by two planes. , windows that may actually be less than one square meter , it costs 4 square meters.
Some merchants are less than 1 .5 square meters by 1 .5 square meters , in this way, you can save a little money. Although I feel very unreasonable , but there is no way , less than 1 . The window of 5 square meters still needs 1 .5 square meters of materials to produce , the seller will not suffer this loss , direct transfer to consumers. Broken Bridge aluminum quote trap , now some merchants are trying to attract customers , first, attract customers with low unit price , then the merchant will increase the cost of accessories such as column (mid-end), beam, locator, waterproof adhesive, etc. , merchants confuse consumers with low unit price , finally, the overall price is not cheap at all.
2 . Measurement
You must be present at this stage. , cause 1 : determine with the merchant how to design the window and how to open it; Reason 2 : supervision and measuring personnel must carefully measure , if the size is not correct , it will cause installation difficulties. , therefore, Windows will be used. For example, the measured value is smaller than the actual value. , the window will be smaller than the actual one. , need a lot of glue filling , there may be risks of gap leakage and instability; The measured value is larger than the actual value. , the window is larger than the actual one , workers will install violently when installing , may cause damage to the wall or window itself. Multi-count area , some merchants will calculate more area when measuring , for example , less than 2 square meters , calculated by 2 square meters , there is also a multi-count loss , for example 10 square meter window , some merchants add a loss of 12 square meters , calculate 2 square meters more. (Quote low multi-computing area)
3 . Glue
A large number of silicon sealant and foam glue are used when installing windows. , poor quality glue will be an important source of indoor formaldehyde , it is best to let merchants choose the best. You can also buy it yourself , but be sure to negotiate with the merchant , because the rule of some merchants is that if you use the glue you prepared yourself , they are not responsible for any problems with the windows (black heart). . Waterproof adhesive fees , when consulting the price of broken bridge aluminum doors and windows, be sure to ask if waterproof adhesive is charged. , because many broken bridge aluminum merchants lower the unit price , then make up the difference by adding waterproof adhesive fees. , waterproof adhesive the cost is a few hundred yuan less , more than one thousand yuan.
4 . Installation
More should be supervised , see if it is consistent with the agreement in the contract , for example, hardware used , window opening method , and other details , if it is well, it will be difficult to change it again. Glue must be in place , if not in place , there will be risks of looseness, air leakage and water leakage.
5 . Glass Hollow
The purpose of glass hollow is to achieve the effect of heat preservation , generally choose 9mm or 12mm thick , and the hollow sealing must be ensured. If the seal is not good, it will not only cause poor heat preservation effect. , it is more likely that water mist will appear in the middle of two layers of glass. , it can't fade for a long time , it can't be wiped.
6 . Brand
Doors and windows are not like building materials such as floor paint. , few big brands , most of them are small stores , they bought raw materials , then process according to the measured size , when purchasing, you must pay attention to the brand of profiles they use. , generally, the best profile brand is : domestic : fengaluminum, Zhongwang, etc.; Import : german Vika, German hansnooker, German vidun, etc.
7 . About Noise
If your budget is not high , I can't buy thick windows , there is a simple way , just don't remove the original window , add another layer of window (can be added between living room and balcony) , the effect of soundproof and dustproof is also very good , it may not be beautiful enough. And this method can also be used in bedrooms.
