During the decoration process, the choice of doors and windows is crucial. Broken bridge aluminum doors and windows have become the first choice for many families due to their excellent performance. But facing the dazzling array of products on the market, how to choose suitable broken bridge aluminum doors and windows?

1. Understand the structure and principle of broken bridge aluminum doors and windows

Broken bridge aluminum doors and windows are based on ordinary aluminum alloy doors and windows, with nylon insulation strips added, and the aluminum alloy profiles are divided into two parts, inside and outside, which effectively prevents the conduction of heat, thereby achieving good thermal insulation effect.

2. Key points to pay attention to when purchasing

1. Aluminum quality

High-quality broken bridge aluminum doors and windows should use primary aluminum, with a smooth surface and uniform color. The quality of aluminum can be judged by observing the cut surface and feel of the aluminum.

For example, some well-known brands of aluminum are pure in material, high in strength, and not easy to deform.

2. Insulation strips

Nylon PA66 insulation strips are the first choice, which are resistant to high temperature, corrosion, and have good thermal insulation performance. Pay attention to the width and shape of the insulation strip. Generally speaking, wider insulation strips have better insulation effect.

For example, some brands of insulation strips adopt a multi-cavity structure, which greatly improves the insulation performance.

3. Hardware accessories

Hardware accessories directly affect the service life and use experience of doors and windows. Well-known brands of hardware accessories, such as German Hobo and Sieglia, have better quality assurance.

Like window hinges and handles, high-quality hardware accessories open and close smoothly and feel comfortable.

4. Glass

Choose different types of glass according to actual needs. If you have high requirements for sound insulation, you can choose hollow laminated glass; if you pay attention to heat preservation, you can choose Low-E glass.

Suitable for families living on the roadside, choosing glass with good sound insulation can effectively reduce noise interference.

5. Sealing performance

High-quality sealing strips can effectively prevent rain and air infiltration. Common sealing strip materials are EPDM rubber and silicone rubber.

Suitable for some areas with more wind and rain, doors and windows with good sealing performance can keep the room dry.

3. Brand and price selection

There are many brands of thermally-broken aluminum doors and windows on the market, and the prices vary. When choosing a brand, you should consider factors such as the brand's reputation and after-sales service. Don't just look at the price, because too low a price often means that the quality cannot be guaranteed.
