Time : 2021-07-01 Hits : 3

Faced with the increasingly serious global warming problem, controlling greenhouse gas emissions and slowing down the global temperature rise have become one of the thorny issues that all countries in the world need to deal with urgently. Energy saving and emission reduction is the only way for global economic development.

Energy saving and emission reduction is the only way for global economic development. Energy saving of building doors and Windows is an important part of energy saving and emission reduction in the whole society. At present, the world's main countries are actively promoting the energy-saving work of building doors and Windows. German current doors and Windows energy-saving standards for 1.0W /㎡. K ≤ UW ≤ 1.2W /㎡. K, and requirements before 2021, all building energy saving to achieve zero energy consumption, that is, the so-called "passive ultra-low energy consumption building" to meet this requirement. According to the climatic conditions in Germany, the insulation performance of the doors and Windows must be UW ≤ 0.8W /㎡. Of course, it is not only a simple reduction of UW value, other related product performance indicators should also be matched with it. It is just that the UW value of doors and Windows is more difficult to reduce, and is also a major indicator.
