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 "Broken Bridge Insulated Aluminum"?
The “bridge†of the name “Broken Bridge Insulated Aluminum†refers to the “hot and cold bridge†in the sense of material science, while the word “break†refers to the action, that is, “interrupting the bridge between hot and coldâ€.
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 is the aluminum alloy disconnected from the middle, it uses a heat insulation strip to connect the broken aluminum alloy into one, so the heat is not easy to pass through the entire material, the thermal insulation properties of the material will be better, This is the origin of the name “Broken Bridge Insulated Aluminumâ€.
Broken aluminum doors and windows generally include two main parts: broken bridge thermal insulation aluminum and hollow glass.
Analysis of the advantages of broken bridge heat insulation aluminum:
1. Broken bridge insulation aluminum insulation is good. Adopting soft insulation inside and outside the frame, combined with EPDM rubber seal on the frame, close tight, airtight, particularly watertight performance, superior insulation properties; sash with insulating glass structure, so that the windows really show sound insulation, Heat, heat preservation, excellent function, a lot of savings in mining and refrigeration costs, K value of heat transfer coefficient detected 1.8-2.5w/2K below, energy-saving effect is significant, a few years of energy-saving costs can make up for 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 streamlined design, luxurious style.
11. Broken bridge insulation aluminum green building materials, circular 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.
Material Characteristics of Insulated Aluminum in Broken Bridge
(1) Broken Bridge Aluminum alloy doors and windows belong to the higher grade aluminum alloy doors and windows. It is the fifth generation of new energy-saving insulation doors and windows following wooden windows, iron windows, plastic steel doors and windows, and ordinary color aluminum alloy 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 commonality 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.
What should you pay attention to when buying broken aluminum doors and windows?
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.
