Broken bridge thermal insulation aluminum alloy doors and windows have outstanding advantages such as high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good corrosion resistance, high comprehensive performance, long service life, and good decorative effect. More and more favored by the market. High-end thermal insulation aluminum alloy doors and windows with broken bridges have gradually become the first choice for high-end architectural windows.

　　Why is it called "Broken Bridge Thermal Insulation Aluminum"?

　　"Broken bridge thermal insulation aluminum" The "bridge" in the name refers to the "cold and hot bridge" in the sense of material science, and the word "break" means action, that is, "break the cold and hot bridge".

　　Specifically, because aluminum alloy is a metal, heat conduction is relatively fast, so when the indoor and outdoor temperature is very different, aluminum alloy can become a "bridge" for heat transfer. Such a material is made into doors and windows, and its thermal insulation performance is not good. Great. The broken aluminum is to disconnect the aluminum alloy from the middle, and it uses heat insulation strips to connect the disconnected aluminum alloy into one body, so that the heat will not easily pass through the entire material, and the heat insulation performance of the material will be better. This is the origin of the name "Broken Bridge Thermal Insulation Aluminum".

　　Analysis of the advantages of broken bridge thermal insulation aluminum:

　　1. Broken bridge thermal insulation aluminum has good thermal insulation. The inner and outer frames of the heat insulation profile are softly combined, and the frame is sealed with EPDM tape, which is tightly closed, has excellent air and watertight performance, and has superior thermal insulation performance; the window sash adopts hollow glass structure, so that the window truly shows sound insulation and insulation. It has excellent heat, heat preservation and functions, and saves a lot of heating and cooling costs. The heat transfer coefficient K value is tested to be below 1.8-2.5w/2K. The energy-saving effect is significant. The energy-saving cost of several years is enough to make up for the initial investment.

　　2. The thermal insulation aluminum waterproof function of the broken bridge. Utilizing the principle of pressure balance, a structural drainage system is designed with drainage outlets for smooth drainage and good water tightness.

　　3. The thermal insulation aluminum of the broken bridge prevents condensation and frost. Broken bridge aluminum profiles can achieve three-way sealing structure for doors and windows, and most of them can even achieve 8 sealings, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of air and water, significantly improve the water tightness and air tightness of doors and windows, and achieve clean and bright windows. effect.

　　4. Design of thermal insulation aluminum mosquito screen window for broken bridge. The invisible screen window can be installed and used inside and outside. It is anti-mosquito and flies, especially suitable for mosquito-prone areas in the north. You can also choose anti-theft screens with anti-theft function.

　　5. Thermal insulation aluminum anti-theft and anti-loose device for broken bridge. Equipped with unique multi-point hardware locks to ensure the stability and safety of the windows in use.

　　6. Broken bridge thermal insulation aluminum noise and sound insulation. The structure has been carefully designed with tight joints. As a result of the test, the air sound insulation can reach 30-40db, which can ensure that residents within 50 meters on both sides of the expressway will not be disturbed by noise, and the neighboring downtown can also ensure that the indoor is quiet and warm.

　　断桥隔热铝的材料特性

　　(1)断桥铝合金门窗是属于较高档的铝合金门窗，它是继木窗、铁窗、塑钢门窗和普通彩色铝合金门窗之后的第五代新型保温节能性门窗。它的表面可以涂装成各种各样的颜色。

　　(2)断桥彩色铝合金门窗的组成结构是结合了木窗的环保，铁窗、钢窗的牢固安全，塑钢门窗保温节能的共性。其结构比普通铝门窗复杂，成本较高，普通彩铝不具有隔热条，不保温不节能，只是在表面做喷图处理。

　　(3)断桥铝合金门窗的型材断面壁厚严格遵循国家标准。 壁厚要求都必须在1.4到2.0mm之间，因为壁厚薄关系到组装技术和组成门窗的牢固安全问题。而普通彩铝门窗壁厚要一般在1.4mm以下。

　　(4)断桥彩色铝门窗是采用3mm以上的专用角码进行组角，组角处要注入组角胶来进行密封。而普通门窗则仅靠拉铆钉或者螺丝连接而成，其牢固安全程度则差，但造价低。而组装好的彩色断桥铝门窗成人站立于上走动也不会有问题。成套设备组装出来的和用人工现场操作组装的在技术上要求上都相差甚远。专用断桥铝型材和普通铝型材不是同一个档次，是不能比较的。

　　门窗消费历来被称为猫腻多、增项多，各类天花乱坠的收费项目多，小编掰开揉碎了把门窗那点事儿给大伙儿说说清楚，也算普及一下门窗知识，教大家以后更换新门窗时做到不被各种奸商所蒙骗!

　　案例分享

　　01案例一：

　　商家在未测量前的报价，与最终实际测量后的报价，相差巨大，有时甚至超过一倍。

　　例如：测量定金后，等工人到其家中测量门窗面积时，往往会以多加一定量的面积损耗为由抬高价格，杀业主个措手不及。

　　门窗的安装过程中，诸如拆除旧窗工人直接拿走不给钱、密封条还需另付费、L型窗尺寸按外口计算且不减除拐点处加强柱的尺寸面积等现象。

　　对应办法：仔细看完以下军长去哪儿揭秘门窗术语，门窗猫腻排行榜第一名：横梁，立柱，转角立柱，护框等，此类增项是最容易将合同金额直线拉升的项目，所以在了解商家价格时，一定将此价格问个清清楚楚，每平米报价中都包含哪些，哪些是需要单独收费的，收费金额等，最好能让商家在一些凭证上写明平米报价中所包含的所有明细。

　　02案例二：

　　门窗用了不到半年，窗户中空玻璃中间进气，导致窗户中间有雾气，影响使用及美观!

　　对应办法：门窗安装完毕后，业主需亲自检查窗户密封条是否紧密牢固，否则一旦出现以上问题，只能重新更换新玻璃，给业主生活造成一些影响

　　03案例三：

　　拆下的旧窗户工人直接拿走

　　If it is said that the merchants help the owners to dismantle the old doors and windows before installing the plastic steel doors and windows is fulfilling their "free" demolition duties, then it seems impossible to take them away. After all, it is the property of the owner's family. The fact is that this is also a manifestation of profiteers (sometimes the professional quality of workers represents the quality of the brand). If the owner favors the workers and actively asks the workers to take it away, it is a bit too much for the workers to take it away without saying hello. What's that. . .

　　Solution: Ask in advance whether it’s free to remove old windows, whether to recycle old windows, your own home stuff, why don’t you sell some money? You can’t let the business make money for your new windows and also make money for your old windows.

　　note:

　　It is very important to sign a rigorous contract with the merchant. It is necessary to implement the processing technology, detailed size and area, installation technology, installation date, thickness of insulating glass, brand of hardware, warranty commitment period, etc. into the contract in the form of white paper and black letters. Foolproof.

　　How to judge the pros and cons of bridge aluminum profiles?

　　a. Profile wall thickness: Generally, for home improvement products, most door and window factories choose products with high yield, that is, products with relatively thin wall thickness to reduce the cost. The thickness of 1.3 is lower than the national standard. The national standard stipulates: the thickness of the profile should be greater than or equal to 1.4mm.

　　b. Heat insulation strips: the most critical part of the aluminum profile for the broken bridge is the heat insulation strips. 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 be serious. Affect product life and safety.
