Comprehensive energy-saving environmental protection is imperative concern doors

Means to achieve energy-saving windows and doors on the main physical properties airtight, watertight, sound insulation, insulation, insulation and other products to certain standards of doors and windows. In developed countries, energy-saving windows and doors penetration rate has reached 100 percent, while China accounted for only 0.4% of total doors and windows, energy-saving windows and doors of the building caused by the low penetration rate is more than three times the energy consumption in developed countries.handrail for curved stairs outdoors

Last year, a television station reported that a piece of news in the country, the so-called energy saving windows and doors accounted for 45% -50% of building energy consumption, accounting for 20% of total energy consumption, energy-efficient doors and windows of buildings has become the weakest link. Building energy saving windows and doors is only part of the effect is difficult to be monitored throughout the building structure, roof, walls, foundation, doors, windows, etc., according to the relevant data, the heat loss windows and doors accounted for 40% of the total heat loss of the building about.floor decking for outside

With the rapid development of urbanization, China's building energy consumption increased significantly in recent years, the data show that the current building energy consumption has reached 32% of energy consumption of the whole society, with an annual production of building houses approximately 13% energy, construction the total energy consumption has reached 45% of the total energy consumption. At present, China is in the historical period of industrialization, urbanization and the rapid development of new rural community development, and further promote building energy efficiency, accelerate the development of green building facing a rare historical opportunity. Huge building energy consumption, has become a huge burden on the national economy, a comprehensive energy conservation is imperative.outside patio flooring
