Thermal Break Windows Extrusion Dies

Broken bridge aluminum doors and windows are a relatively common door and window product on the market. They have received widespread attention and application in the construction industry for their unique design and excellent functions. The principle of broken bridge aluminum doors and windows is to achieve thermal insulation, sound insulation, energy saving and other effects by interrupting the heat conduction between the two layers of aluminum profiles inside and outside the door and window frame.

The design concept of broken bridge aluminum doors and windows is derived from the basic principle of heat conduction. Aluminum alloy is a material with good thermal conductivity, and the double-layer frame structure of doors and windows will cause energy loss due to heat conducted indoors and outdoors through doors and windows. In order to solve this problem, broken bridge aluminum doors and windows adopt broken bridge technology, that is, a layer of broken bridge aluminum profiles is set between the inner and outer layers of the door and window frame. The special design of this aluminum profile effectively prevents the conduction of heat, thereby achieving a good heat insulation effect.

The thermal insulation effect of broken bridge aluminum doors and windows is mainly reflected in the following aspects:

1. The use of thermal bridge aluminum profiles

The key technology of broken bridge aluminum doors and windows is the use of thermal bridge aluminum profiles. This kind of profile is filled with materials with low thermal conductivity, which prevents the conduction of indoor and outdoor heat. At the same time, heat insulation strips are installed on both sides of the aluminum profile to further reduce heat transfer. These designs make the broken bridge aluminum doors and windows have good thermal insulation properties and can effectively reduce the energy consumption of indoor air conditioning.

2. Two-way sealing system

In addition to using thermal bridge aluminum profiles, broken bridge aluminum doors and windows also adopt a two-way sealing system. This sealing system can effectively prevent the penetration of air and water, improving the sealing performance of doors and windows. Through good sealing performance, broken bridge aluminum doors and windows can prevent the transfer of hot and cold air, keep the indoor temperature stable, and provide a comfortable living environment.

3. Multi-layer soundproof glass

Sound insulation performance is also a major feature of broken bridge aluminum doors and windows. In order to improve the sound insulation effect of doors and windows, multi-layer sound insulation glass is used in broken bridge aluminum doors and windows. This kind of glass has high sound isolation performance and can effectively reduce the transmission of indoor and outdoor noise. Especially in bustling areas or places with high noise, broken bridge aluminum doors and windows can provide residents with a quieter living environment.

4. Energy conservation

The thermal and sound insulation properties of broken bridge aluminum doors and windows not only provide residents with a comfortable living environment, but also save energy. By reducing the transfer of indoor and outdoor temperatures, broken bridge aluminum doors and windows can reduce the frequency of air conditioning use and energy consumption, thereby achieving the purpose of energy saving and emission reduction. With long-term use, this will have a positive impact on environmental protection and sustainable development.

in conclusion

As a door and window product with good heat insulation, sound insulation and energy-saving properties, broken bridge aluminum doors and windows are favored by many consumers. Its principle is to improve the heat insulation effect of doors and windows by cutting off the heat conduction between the inner and outer layers of aluminum profiles. At the same time, the broken bridge aluminum doors and windows also use a two-way sealing system and multi-layer soundproof glass to further improve the performance of the doors and windows. By saving energy and providing a comfortable living environment, broken bridge aluminum doors and windows have made important contributions to people's quality of life and environmental protection.
