Does the security door installed by the developer need to be replaced
In the purchase of new houses, developers generally have installed security doors and windows. Many families are struggling with whether to replace them when they are decorating. Let me give you some advice.
Does the security door need to be replaced
1. If the developer is not installed security doors but ordinary doors, it is best to replace.
2. If the security door reserved by the developer, we need to check the steel seal mark on the side of the door to know which level the security door is in. The anti-theft effect of class A is the best, and the anti-theft opening time is 30 minutes (15 minutes for class B, 10 minutes for class C, and 6 minutes for class D). Usually at home use a, B level on the line. Considering the decoration budget, the installation of a, B level can not be changed!
Of course, it's not over. The anti-theft door is divided into the main body and the lock cylinder. The fact that the main body does not need to be replaced does not mean that the door lock cylinder does not need to be replaced. There are also levels of lock cylinder, class A, class B, super class B (also known as class C). It is better to install class C lock cylinder for home installation. But at this time, we need to remind you that even if the developer is installing class C lock cylinder. After we check in, it's better to replace the lock cylinder in time. Because many residential new house decoration, are unified in a manufacturer to buy the lock cylinder, in order to prevent some keys can open a few doors, we suggest that you replace the lock cylinder is the most safe. In addition, replace the lock cylinder must find a professional lock company, not to save money installed a bargain.
Do developers need to change the security windows
1. If the developer is reserved for plastic steel windows, in order to long-term use, it is best to replace!
2. If the aluminum alloy doors and windows reserved by the developer, the profile thickness and other performance problems of the aluminum alloy windows should be checked to determine whether they need to be replaced. In addition, the beauty of anti-theft window is also one of the audit standards. If the quality of the window is OK and the beauty is acceptable, then there is no need to replace it. Of course, now some families are more high-end, installed broken bridge aluminum, this is also feasible.
Conclusion: the security door does not need to be replaced, the lock cylinder needs to be replaced. If the window, you can feel whether to replace it according to the conditions of your home!
