The most prominent feature of Low-E glass is its excellent heat insulation performance. Its surface is coated with a low-emissivity film, which can effectively reflect infrared rays and reduce heat loss. In winter, the internal heat will not be lost through the glass, effectively maintaining the indoor temperature; while in summer, Low-E glass can prevent external heat from entering, keeping the indoor environment cool. This dual effect makes Low-E glass an ideal choice for energy-efficient buildings, significantly reducing the energy demand for air conditioning and heating. Low-E glass also has a certain ability to filter ultraviolet rays, effectively blocking most ultraviolet rays from entering, thus protecting indoor furniture and decorations from ultraviolet damage and extending their service life.
