It is worth thinking about your house protection at the stage of designing it. At present times, the sense of security is one of the main needs of each person. It has a significant impact on the comfort and quality of life. First of all, windows and doors should be properly protected against burglary using appropriate anti-burglar systems. The right combinations of fittings (RC) in connection with laminated glass (VSG) and a lockable handle guarantees the best protection of your house. There are a few resistance categories (RC) which are regulated by the European Norm. The higher the category, the more efficient protection.
