We doorwin has revolutionized the energy efficient windows by various components such as the glass, frame and hardware what make our window energy efficient.
Those components that provide substantial protection from heat gain and heat loss and reduce the energy consumed by the whole building are considered energy efficient.
Double glazed windows
An ideal energy efficient solution is to reduce all forms of heat transfer. Double glazing is considered the vehicle for all high-performance windows, in climates hot, cold and mixed. When combined with low-e glass on at least one pane and argon gas in between, double glazing provides the best thermal performance. U-values as low as 1.8 are possible, compared with about 5 in the of a single-glazed clear window.
The narrowest air gap used in double glazing is 6 mm but this should be avoided unless there is no alternative. The use of wider gaps (10-20 mm) will improve the U-value and the configuration of 5mm glass +12air+5mm glass is the most popular with inexpensive price. In addition to double glazed windows, we also offer triple glass option to reach extraordinary great in performance.
Our double glazing glass and triple glazing glass have passed SGCC (Safety Glazing Certification Council )and IGCC ( Insulating Glass Certification Council) which means they are qualified for the Safety standard for safety glazing used in buildings and safety performance specifications.
