I often hear that broken bridge aluminum windows are the best for home decoration, but I have never understood it carefully.

I recently had my windows replaced, and I specifically asked the installer.After listening to the explanation, I realized that he is so knowledgeable. many! Today I would like to share with you to see if your understanding of broken bridge aluminum is in-depth enough.

Why is it called \”Broken Bridge Aluminum Window\”

The master told me that the reason why it is called so is mainly because the manufacturing process of this profile is relatively special.

The material of the broken bridge aluminum itself is aluminum alloy, but it is not a whole. It is formed by cutting aluminum alloy profiles, adding a material with low thermal conductivity in the middle, and then connecting them.

This low thermal conductivity material is usually nylon insulation stripbecause of its The existence of aluminum alloy blocks the heat transmission and the transportation of cold air, breaks the bridge of hot and cold transportation, and forms a \”broken bridge\”. That\’s why this profile is called: broken bridge aluminum. .

Advantages of bridge-breaking aluminum

Based on its bridge-breaking process, it has two more advantages than traditional aluminum alloy windows:

①Insulation and warmth

As mentioned above, the heat insulation strips added to the aluminum alloy break the heat and cold exchange between the inside and outside of the window. Even if the weather outside is hot or cold, it can It blocks the transmission of heat and cold air and avoids changes in indoor temperature, so it has better insulation and warmth retention.

②Sound insulation

The broken bridge aluminum has a cavity structure and is made of seamless welding. It has excellent sealing and is paired with double-layer glass, which has a very good sound insulation effect.

The demand for sound insulation and heat preservation in modern residences is increasing, which makes broken bridge aluminum more and more popularNowadays, most of the windows on the market are broken bridge. Aluminum windows, plastic steel windows and aluminum alloy windows have long been marginalized

How to choose broken bridge aluminum

Although broken bridge aluminum windows have unique advantages, if you choose incorrectly, you will still not be able to achieve the desired results, especially today\’s merchants, who have many tricks. Don\’t be careful!

Through personal purchasing experience, I have summarized 5 selection tips for you. You may wish to use them as a reference if necessary:

①Choose thick or thin

Wall thickness is an indicator of the thermal insulation effect and strength of broken bridge aluminum. Logically speaking, the thicker the wall, the better. However, the current conditions in residential areas are poor. It’s not considered too bad. Generally, it’s enough to choose a wall thickness ≥1.4mm.

② Choose PA66 instead of PVC

The most important part of the broken bridge aluminum is the insulation strip. The common materials are nylon and PVC. It is recommended that you do not choose PVC insulation strips. The durability is low. Spend more money and choose PA66 nylon insulation strips, which are anti-aging and have a long service life.

③Choose double-layer glass instead of single-layer glass

If you have the ability, you must choose double-layer glass. Whether it is sound insulation or safety, a common combination is 6mm+12A+6mm. . (6mm is the thickness of the glass, 12A is the thickness of the filling layer inside the glass)

④Choose big brand hardware rather than inferior products

Hardware is an indispensable part of windows. For long-term use, you must buy big brands.

⑤ Compare shopping

Go to several more stores, ask about the price, be optimistic about the quality, and make a comprehensive decision before making a decision. It’s better than being tricked by a merchant!
