The difference between a broken bridge sliding window and a regular sliding window
Author:
The main differences between a broken bridge sliding window and a regular sliding window are reflected in the material structure, performance, and design details. The specific differences are as follows:
1. Materials and Structure
Broken bridge sliding window: Made of broken bridge aluminum profiles, with insulation strips added in the middle of the window frame to form a "broken bridge" structure, effectively blocking heat transfer. The borders are mostly designed with closed ends, and the track adopts a high-low structure to prevent rainwater from flowing back.
Ordinary sliding window: usually made of a single aluminum alloy profile, without insulation strips, with open frame design and simple track structure.
2. Thermal insulation and sound insulation
Broken bridge sliding window: The insulation strip significantly improves the insulation performance, reduces heat loss in winter, and reduces air conditioning energy consumption in summer; Hollow glass and multiple sealing designs (such as double wool strips and rubber strips) enhance the sound insulation effect.
Ordinary sliding windows: Poor thermal insulation performance, fast indoor and outdoor heat exchange; The sound insulation effect is weak, relying only on the sealing of wool strips, and is easily affected by external noise.
3. Sealing and waterproofing
Broken bridge sliding window: sealed with rubber strips, the window frame is tightly connected, with better water and air tightness, which can effectively prevent rainwater infiltration.
Ordinary sliding windows: rely on the physical fit between the track and the window sash, with poor sealing, and long-term use may result in water leakage.
4. Safety and wind resistance
Broken bridge sliding window: Equipped with multi-point locks, it has stronger wind pressure resistance performance (the main load-bearing members have been strengthened), and can be equipped with diamond mesh protective railings, balancing safety and aesthetics.
Ordinary sliding windows: have weak wind resistance performance (relying on pulley load-bearing), and cannot effectively protect children from climbing or falling risks.
5. Price and cost-effectiveness
Bridge cutoff sliding window: the material and process are complex and the price is high (hundreds to thousands of yuan), but the long-term energy-saving effect and durability (anti-aging and corrosion resistance) can make up for the initial cost.
Ordinary sliding window: lower price, but shorter service life, prone to fading, deformation and other problems.
