sound insulation and heat preservation effect of doors and windows, of course, choose broken bridge aluminum doors and windows yes. Broken bridge aluminum doors and windows although it is good, the price is also high, especially now mix the fictitious with the genuine in the market, if?] With bright eyes and small skills of selecting doors and windows, it is especially easy to be cheated. Merchant secret: 4 ways to teach you to choose correctly broken bridge aluminum doors and windows! Spend less money.

Therefore, the quality of heat insulation strip directly affects broken bridge aluminum doors and windows the sealing effect.
Broken bridge aluminum doors and windows the thermal insulation strip must use PA66 nylon thermal insulation strip, and PVC plastic strip light-emitting, but the surface is not smooth; The surface of the real nylon strip is smooth and symmetrical. If the heat insulation strip is deformed, it will not be tightly connected with the aluminum alloy profile, which will affect the sealing effect of the window. PVC heat insulation strip is easily deformed due to the influence of heat expansion and cold contraction; While nylon strip is hard, firm and stable, it is not easy to deform.
