Compared with ordinary doors and windows, Lumei energy-saving doors and windows have the following advantages:
1. Super energy saving
Helping environmental protection low-carbon doors and windows are made of polymer composite profiles, and the heat transfer coefficient is 1/1250 of that of aluminum profiles; the multi-chamber structure design can effectively block the convection of indoor and outdoor cold and hot air, thereby saving cooling and heating costs. However, most doors and windows on the market are single-cavity structures, which cannot block the convection of cold and hot air. It takes a long time to turn on heating and cooling equipment to maintain the indoor temperature, resulting in a waste of energy!
2. Super mute
The importance of quiet and comfortable sound insulation for doors and windows is very important. If the sound insulation performance of doors and windows we choose is poor, it will seriously affect our sleep, work and study. The multi-layer insulating glass configuration can block and reduce noise layer by layer, and enjoy home life quietly
3. Super sealing performance
Keraoen doors and windows are sealed with "aviation-grade" sealing strips and patented water-swelling strips; three flexible sealing designs, and the 90° corner adopts an integrated vulcanization and corner forming process to form an integral continuous sealing surface to ensure the entire window. air tightness and water tightness.
4. The whole system is self-deep processing tempered insulating glass
Glass accounts for 80% of the total area of doors and windows, and the performance of glass directly affects the performance of the entire window. Lumei has an independent high-performance glass production line, and all doors and windows use self-deep-processed tempered insulating glass, Low-E glass, laminated glass, etc.; however, most door and window manufacturers on the market use the form of cooperation with glass processing factories, which cannot be To control the performance of glass from the source, it is easy to make the performance of the whole window not reach the best.
