How to distinguish a single broken bridge from a double broken bridge with naked eyes

Sound insulation, heat insulation, sealing and pressure resistance.

The main differences between double broken bridges and single broken bridges are as follows.

1, the sound insulation effect of double broken bridge is better than that of single broken bridge. The sound insulation effect of double broken bridge doors and windows will be about twice as good as that of single broken bridge doors and windows, and the external noise will hardly come in after installation.

2. Double broken bridge has better thermal insulation effect than single broken bridge. The research shows that the temperature difference between indoor doors and windows is 3 degrees in the summer of 39 degrees, and the indoor temperature of double broken bridges is even lower.

3. The double broken bridge is superior to the single broken bridge in sealing performance. In contrast, the doors and windows of double broken bridges are less prone to water ingress and more moisture-proof.

4. Double broken bridges have better compression resistance than single broken bridges. In extreme weather such as typhoon days and sandstorms, the doors and windows of double broken bridges are more resistant to knocking and compression.
