ã€China Aluminum Industry Net】Aluminum alloy heat insulation aluminum alloy doors and windows with high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good corrosion resistance, high overall performance, and service life Long, good decorative effect and other outstanding advantages, more and more favored by the market. The high-end broken bridge heat-insulating aluminum alloy doors and windows have gradually become the preferred products for high-grade architectural windows.
Why is it called "Breaked Bridge Insulated Aluminum (The term "Aluminum" is provided by Industry Encyclopedia)?"
"Broken-aluminum insulated aluminum" The name "bridge" refers to the materialistic "hot and cold bridge" and the word "broken" refers to the action, that is, "breaking the bridge between hot and cold."
Specifically, because the aluminum alloy is a metal, the heat conduction is relatively fast, so when the indoor and outdoor temperatures are much different, the aluminum alloy can be a “bridge†to transfer heat. Such a material is used for doors and windows, and its thermal insulation performance is not Good. The broken bridge aluminum (the entry "Bridge Aluminum" is provided by the Industry Encyclopedia) is the aluminum alloy disconnected from the middle, it uses insulation strips to connect the broken aluminum alloy as one, so the heat is not easy to pass the whole Material, the insulation properties of the material will also become better, this is the name of "breaking bridge insulation aluminum" origin.
Analysis of the advantages of broken bridge heat insulation aluminum:
1. Broken bridge insulation aluminum insulation is good. The use of soft insulation inside and outside the frame of the combination, the use of EPDM rubber seal on the border, close tight, airtight, watertight (word "water tightness" provided by the Encyclopedia of the industry) can be particularly good, superior insulation properties; The sash is made of an insulating glass structure, which makes the windows truly show sound insulation (the term "soundproofing" is provided by the Encyclopedia of the industry), heat insulation, heat preservation, excellent function, substantial savings in the cost of picking and cooling, and the heat transfer coefficient K value is detected by 1.8 - Below 2.5w/2K, the energy saving effect is significant, and the energy saving cost for several years is enough to make up for the previous investment.
2. Broken bridge insulation aluminum waterproof function. The principle of pressure balance is used to design a structural drainage system with drainage outlets, smooth drainage, and good water tightness.
3. Broken bridge insulation aluminum anti-condensation, frost. Broken bridge aluminum can realize the three-door sealing structure of doors and windows, and can even reach 8 seals, reasonably separate water vapor cavity, successfully realize gas-water equal pressure balance, significantly improve the watertightness and airtightness of doors and windows, and achieve a clear and bright window. effect.
4. Broken bridge insulated aluminum mosquito screen design. Invisible screens can be installed and used inside and outside, with anti-mosquito and flies, especially for northern mosquitoes and insects. Also choose security screens, with anti-theft function.
5. Broken bridge insulated aluminum anti-theft, anti-loosening device. Coupled with a unique multi-point hardware lock to ensure the stability and safety of the window in use.
6. Broken bridge insulation aluminum noise noise. The structure has been carefully designed and the joints are tight. The test results show that the sound insulation of the air can reach 30--40db, and the residents within 50 meters on both sides of the highway can be protected from noise. The adjoining downtown can also guarantee the quiet and warm interior.
7. Broken bridge insulation aluminum fire protection function. Aluminum alloys are metal materials and will not burn.
8. Broken bridge insulation aluminum sand, wind pressure. The hollow frame adopts hollow design, strong resistance to wind pressure deformation, and good anti-vibration effect. It can be used in high-rise buildings and residential houses. It can design large-area windows and have a large lighting area. This type of window is more airtight than any aluminum or plastic window. It can ensure that there are no dust in the indoor sill and floor in areas with large sandstorms.
9. Broken bridge insulation aluminum high strength type, maintenance-free. The broken bridge aluminum door form has high tensile and shear strength and thermal deformation resistance. Rugged and durable aluminum profiles are not susceptible to acid and alkali corrosion, are not easy to fade yellow, and almost do not need maintenance.
10. The broken bridge is made of heat-insulating aluminum in many colors and is very decorative. The indoor and outdoor surfaces of the doors and windows can be different colors to meet the customer's preference for color effect and the aesthetic needs of the color space, in line with the architect's personalized design requirements. Aluminum profiles (entry "profiles" provided by the Encyclopedia of Industry) use streamlined design, luxurious style.
11. Broken bridge insulation aluminum aluminum green building materials, recycling economy. Broken aluminum doors and windows in the production process will not only produce harmful materials, all materials can be recycled and recycled, is a green building materials and environmental protection products, in line with human sustainable development.
12. Broken bridge insulation aluminum open more form, comfortable and durable. There are flat open type, introversion type, top suspension type, push-pull type, flat open and introverted and compound type, etc., applicable to public buildings, residential quarters and municipal projects; high-quality hardware accessories are durable, humanized operation handle design, beautiful and comfortable, easy to open Flexible, each use of the action has been tested, the number of fatigue tests up to tens of thousands of times, sliding easily and silently, mature and perfect doors and windows processing technology, high-precision program control processing center for production, quality and stability guaranteed.
Broken Bridge Insulation Aluminum Material Properties (1) Broken Bridge Aluminum alloy doors and windows are high-grade aluminum alloy doors and windows. It is the fifth generation of new energy-saving insulation energy after wooden windows, iron windows, plastic steel doors and windows and ordinary color aluminum alloy doors and windows. Doors and windows. Its surface can be painted in various colors.
(2) The composition of broken aluminum alloy doors and windows is a combination of the environmental protection of wooden windows, the solid security of iron windows and steel windows, and the commonness of heat preservation and energy saving of steel doors and windows. Its structure is more complicated than the ordinary aluminum doors and windows, and the cost is higher. The ordinary color aluminum does not have heat insulation strips. It does not heat insulation and does not save energy, but it only performs spray pattern processing on the surface.
(3) The wall thickness of the profiles of the aluminum alloy doors and windows of broken bridges strictly follows the national standards. The wall thickness requirements must all be between 1.4 and 2.0 mm, as the thin wall thickness relates to the assembly technology and the solid security issues that make up the doors and windows. The ordinary color aluminum doors and windows should be generally less than 1.4mm.
(4) The color aluminum doors and windows of the broken bridge adopt the special corner code of 3mm or more to make the group angle, and the group corner glue should be injected into the group for sealing. Ordinary doors and windows are made only by pulling rivets or screws, and their solid safety is poor, but the cost is low. There is no problem for adults standing on the walk with the assembled color broken aluminum doors and windows. The assembly of equipment and the use of manual on-site assembly are technically very different. The special broken bridge aluminum profiles and ordinary aluminum profiles are not of the same grade and cannot be compared.
The consumption of windows and doors has traditionally been known as more and more tricky, more items are added, and there are many kinds of fees and charges for small and medium-sized things. The small curtain wall of China's curtain wall nets and smashes and breaks out the doors and windows to tell everyone clearly, and it can be considered as a universal knowledge of doors and windows. , teach everyone to replace the new doors and windows later do not be deceived by all kinds of profiteers!
Case Sharing 01 Case 1:
There is a big difference, sometimes even more than doubled, between the price quoted by the merchant before it is measured and the actual quoted price after the final measurement.
For example, after measuring the deposit, when workers measure the area of ​​doors and windows in their homes, they often raise the price by adding a certain amount of area loss, which is unprepared to kill the owners.
During the installation of doors and windows, such as the removal of old windows, workers do not give money directly, seals need to be paid separately, the L-shaped window size is calculated according to the outer mouth, and the size area of ​​the reinforcement column at the inflection point is not reduced.
Corresponding method: After reading carefully the following commander's secret terms, doors and windows are filled with names: cross beams (words "beam" provided by the Encyclopedia of Industry), columns, corner columns, guard boxes, etc. It is easier to increase the contract amount directly, so when you know the price of the merchant, be sure to ask the price clearly, what is included in the price per square meter, what is the need for separate charges, the amount of charges, etc. Allows the merchant to write all the details contained in the Ming-Ming quote on some vouchers.
02 Case 2:
Windows and doors have been used for less than six months. In the middle of the windows, the windows are filled with air, causing fog in the middle of the windows, which affects the use and appearance!
Corresponding method: After the doors and windows are installed, the owner must personally check whether the window weatherstrip is tight and firm. Otherwise, once the above problems occur, only new glass can be replaced, which will cause some impact on the owner's life. 03 Case 3:
Removed old window workers directly took away If it is said that businesses are installing steel doors and windows to help owners dismantle the old doors and windows to fulfill their "free" demolition duties, it would be unacceptable to take them away, after all, belonging to the owner's home property. . The fact is that this is also a manifestation of profiteering (sometimes the professional quality of the workers represents the quality of the brand). If the owners favor the workers and take the initiative to let the workers take away what they said in the past, the workers do not say hello and they take it away. That's it. . .
Solution: Say in advance whether it is free to demolish old windows, whether to recycle old windows, what to do at home, why not sell some money, not to let businesses make money in your new windows, but also to earn money from your home's old windows:
Signing a rigorous contract with a business is critical. The process, detailed dimensions, installation process, installation date, the thickness of the insulating glass, the brand of the hardware, the commitment period for the warranty, etc. are implemented in the form of written and black letters in the contract. It is foolproof.
How to judge the quality of the aluminum profile?
a, profile wall thickness: generally do home improvement products, door and window factory most selected products with high yield, that is, thinner wall thickness products to reduce the cost, 1.3 thick is lower than the national standard. National standard: The profile thickness should be greater than or equal to 1.4mm.
b. Insulation strips: Insulation strips make the broken bridge aluminum sections a more critical part. PA66 nylon must be used. This is stipulated by the national standard. However, many manufacturers in the decoration market use cheap PVC plastic insulation strips, which will seriously Affect product life and safety.
