Rationel SOLAR is used mostly in office and commercial buildings that have large south and west glass façades, where overheating may occur during the summer months. We offer five types of panes, which limit the amount of sunlight and heat coming into a building, depending on the light and heat . The most important role of South-facing façades is to utilize the available solar energy to heat up the house. Choose modern double or triple-glazed energy windows with a lower U-value and a high g-value, to make use of the free solar heat.
Naturally, as South-facing façades receive the most sun light there is a possibility . Aug Triple glazed windows are known for their ability to maximize energy efficiency in the winter months, but they can also keep you cool in the summer.
Those with a higher U value will let more light in. This will help you keep warm in the winter by letting in more solar.
