Along with the development of the era of science and technology and the improvement of living standards, the state began to build energy-saving calls for a harmonious society, doors and Windows as the structure of the eye and loss of energy consumption accounted for 40% of the total energy losses of buildings, the countries have already taken enough attention, especially in the capital, Beijing has taken the door window heat transfer coefficient of thermal insulation (index), as a mandatory inspection index, also attracted much attention in all over the country provinces and implement, energy-saving doors and Windows have become the mainstream of building doors and Windows.
Energy-saving door window is comprised by section material roughly, hardware, glass and sealing, reach processing craft a few chunk composition, sealing because its place occupies cost inferior, with a few tradition do not take door window the idea of energy-saving standard to affect, be ignored by manufacturer of a lot of doors and Windows all the time, but sealing has crucial effect in door window system.
Sealing strip is installed on the door window frame, door and glass, have excellent elastic performance will the doors and Windows profiles, hardware, glass together, as a whole, according to the constant pressure design basic principle of energy-saving Windows and doors, sealing pressure effect, so as to achieve the three modes and energy-saving standard of door window, to improve the air tightness and water tightness of doors and Windows, sound insulation performance has a crucial role, make the doors and Windows become qualified energy-saving Windows and doors.
Nowadays, most energy-saving doors and Windows are made of rubber. As people pay more and more attention to environmental protection, epdm sealing strips and silicone sealing strips occupy a large market of sealing materials. However, epdm doors and Windows sealing strips still have some weaknesses.
I - ECO doors and Windows sealing strip cladding type is coated by PE outside, high resilience PU foam as the main raw material, the enclosed PP matrix, so the sealing strip compression form, with about 10% of the following ensures that it can be applied in the doors and Windows, sealing strip cladding type sealing, PE coated outside largely increase the service life of the product, not only rich color is gorgeous, but also have more choices, the material of PP matrix of product also has very good fixed effect, can effectively prevent the product shrinkage after successful installation.
I-eco enveloped sealing strip is environmentally friendly and non-toxic, common epe sealing strip is not as long as its service life, after a system of research and testing found that the performance of enveloped sealing strip in long-term use of the discount rate is low, can play a long-term effect of sealing doors and Windows.
