Broken bridge aluminum doors and windows good sealing performance, no deformation. But it has a fatal defect, that is, a circle of rubber strips around the opening fan is cut off at the hinge.
At present, this problem has been solved, the main solution
1. Use broken bridge aluminum casement window dedicated invisible hinge, leather strap is not cut off.
2. The broken bridge aluminum profile is designed as a double frame broken bridge aluminum profile, two cavities, air leakage situation is solved.
The first technology using invisible hinge is estimated to be phased out, because the hardware used for invisible hinge will be deformed under Casement heavy pressure for a long time. The continuous improvement of the sealing structure of the Broken Bridge aluminum profile is the king to solve the sealing problem.
Recommend use compound frame broken bridge aluminum profiles to solve the sealing problem of broken bridge aluminum door and window hinge.
