In order to make the house warmer in the cold winter, we should choose energy-saving insulation doors and windows when buying or renting a house. According to statistics, doors and windows are the openings of buildings for lighting, and they are the weakest link in buildings. The energy lost through doors and windows accounts for 45% to 50% of building energy consumption. In this case, plastic steel doors and windows are our best choice for customized doors and windows. The reasons are as follows:
Plastic steel door and window profile is a composite chemical material, the main component is polyvinyl chloride, and the functional additives are chlorinated polyethylene, titanium dioxide, calcium carbonate, ACR, stabilizer, ultraviolet absorber, etc.
According to the survey, the indoor temperature in winter with plastic steel doors and windows can be 4-5 degrees higher than that in rooms with wooden doors and windows; the effect of using double-glazed glass in northern areas is better.
According to the test conducted by the Institute of Physics, CABR, the heat transfer coefficient of single glass steel and aluminum windows is 64W/M2K; the heat transfer coefficient of single glass plastic steel windows is about 47W/M2K.
Plastic-steel doors and windows have a multi-cavity structure with good heat insulation performance. Its heat transfer performance is very small, only 1/357 of steel and 1/250 of aluminum. It can be seen that plastic doors and windows have significant heat insulation and heat preservation effects, especially for heating Modern buildings with air-conditioning equipment are more suitable.
The heat transfer coefficient of ordinary double-glazed steel and aluminum windows is about 3.7W/M2K; while the heat transfer coefficient of double-glass plastic steel windows is about 2.5W/M2K. Doors and windows account for 30% of the area of the building envelope, and its heat dissipation accounts for 49%. It can be seen that plastic-steel windows have good energy-saving benefits.
The commonality of thermal insulation and energy saving of plastic steel doors and windows is that two different sections are combined by energy-saving insulation strips. Energy-saving insulation strips are also called nylon strips. Its main function is to interrupt the heat transfer and prevent the rapid or slow heat transfer. The function of heat transfer. Its structure is more complicated than ordinary aluminum doors and windows, and the cost is higher. Ordinary color aluminum does not have heat insulation strips, does not keep heat and does not save energy, but only pastes on the surface.
