Perfect waterproof effect: According to the siphon principle of mechanics, the sealing strip is used to form an independent isobaric chamber of the window type, and the external atmospheric pressure is reasonably introduced. Even if windy and rainy, the rain in the isobaric chamber is smoothly excluded outside under the importance of natural gravity, so as to achieve the perfect waterproof effect. With good thermal insulation performance:PA66 high thermal insulation strip, three-layer insulating glass structure, the use of cavity structure glass lamination, greatly improve the thermal insulation performance of the product. It is very good to keep the indoor environment at a comfortable temperature. Good sound insulation performance:Unique sealing structure, so that the whole window has good sound insulation performance. The use of PA66 sealing strips can reduce the noise of the entire window by at least 35 dB. Security and anti-theft:In the city's buildings, the use of monitoring equipment gradually increased, so many people began to pay attention to the use of monitoring equipment. With the improvement of people's awareness of their own safety and living comfort in the society, property safety and so on need to be protected in a wider range!
