The Broken Bridge is mainly used for heat insulation (because the aluminum alloy has strong thermal conductivity). However, there must be a gap between the sliding window fan material and the track. As long as there is a gap, it is impossible to completely heat insulation, so sliding window of the Broken Bridge is a bit of a waste of broken bridge materials. However, hollow glass occupies the vast area among Window users, so the heat insulation effect of hollow glass right is much greater than that little broken bridge aluminum.
Sliding window is also divided into broken bridges and non-broken bridges. I think there is a survey on the Internet that because there is no sealing pressure between the two sliding window fans, air will also penetrate through the gap, and it is not very meaningful to choose broken bridge aluminum.
Ordinary sliding window because the door leaf and the door frame are not closely fitted, and the indoor and outdoor energy convection is relatively fast, it cannot have a good heat insulation effect; Or because of this, when encountering strong winds, the door Leaf will have a slight shaking sound, which will seriously affect the rest.
The doors and windows of the Broken Bridge adopt the soft combination of the inner and outer frames of the heat insulation profile, and the frame adopts the three sealing forms of one adhesive strip and two wool strips, which are tightly closed, with excellent air tightness, excellent water tightness and excellent heat preservation performance; casement hollow glass structure is adopted, which makes the Windows truly show sound insulation, heat insulation, excellent function, and greatly saves the cost of mining and refrigeration. Several years of energy-saving costs are enough to make up for the previous investment.
