At a time when green environmental protection, energy saving, and emission reduction are advocated, every choice in home decoration is related to the quality of life and energy consumption. Low-E glass doors and windows have become the ideal choice for many families to improve living comfort and reduce energy consumption due to their excellent energy-saving performance and environmental protection characteristics. What kind of "black technology" does this seemingly ordinary glass door and window have that makes it a landmark product of green homes?
Coating technology, building an energy-saving barrier
Low-E glass, also known as low-emissivity glass, features a core technology that involves coating its surface with one or more layers of special metal or metal compound films. This layer of film, which is only nanometer-thick, is akin to applying an "energy-saving coat" to the glass, playing a key role in blocking the transfer of heat.
Among the three ways of heat transfer, radiation heat transfer is a significant factor influencing indoor temperature. Ordinary glass has low reflectivity to long-wave radiation, allowing a large amount of heat to easily enter the room through glass radiation or dissipate to the outside. The coating layer of Low-E glass has high reflectivity for long-wave radiation, allowing it to reflect most of the heat. In summer, it can block up to 70% of solar radiation heat from entering the room, effectively reducing the indoor temperature and reducing the frequency and duration of air conditioning use; in winter, it can reflect the heat radiated by indoor objects back into the room, reducing heat loss, keeping the room warm, and reducing heating energy consumption. According to professional tests, buildings equipped with Low-E glass doors and windows can reduce energy consumption by 30% to 50% annually compared to those with ordinary glass doors and windows, resulting in significant energy savings.
Four seasons of protection, enjoy a comfortable life.
The energy-saving advantages of Low-E glass doors and windows are fully demonstrated in the changing of seasons. In the hot summer, the indoor temperature of ordinary houses, exposed to the scorching sun, is often high, and the air conditioner must run for a prolonged period to maintain a comfortable environment. Not only does the electricity bill soar, but it can also cause physical discomfort due to excessive use of air conditioners. Homes with Low-E glass doors and windows can effectively resist the sun's heat. Even at noon, the room can remain relatively calm, and the air conditioning usage time is significantly shortened, which not only saves energy but also creates a comfortable and healthy living environment for the family.
In the cold winter, Low-E glass doors and windows become "warmth guards." Traditional glass doors and windows allow indoor heat to escape quickly, necessitating that heating equipment continue to operate at high loads. Low-E glass, with its excellent thermal insulation performance, locks in indoor warmth, reduces the frequency and duration of heating equipment use and lowers family energy expenses while maintaining warmth. Whether it is the wet and cold winter in the south or the ice and snow in the north, Low-E glass doors and windows can make the home a warm haven.
Practice environmental protection and energy conservation by adopting green concepts.
In addition to the significant energy-saving effect, Low-E glass doors and windows also conform to the development concept of green environmental protection. Reducing energy consumption means decreasing the use of fossil fuels, such as coal and natural gas, thereby lowering the emission of pollutants like carbon dioxide and sulfur dioxide and contributing to improved environmental quality. For home users, choosing Low-E glass doors and windows is not only about creating a comfortable and energy-efficient living space but also about practicing a green lifestyle through practical actions and contributing to the sustainable development of the earth.
Additionally, Low-E glass doors and windows also prioritize environmental protection during the production process. Its coating process utilizes magnetron sputtering technology, which offers the advantages of non-pollution, uniform coating, and a firm film layer. No harmful waste will be generated during the production process, ensuring compliance with environmental protection requirements.
