Which to choose between emissive glass and selective glass?

When choosing a glass for a window, it is important to consider its exposure: low emissive glass for sunless residential areas and selective glass for areas most affected by the sun. We understand the reason why.

The double glass is made up of two monolithic glass sheets usually of 4 mm., or two stratified glass plates, interposed by a duct that can be of aluminum, steel, or insulating material.

The most commonly used solution is the low-emissive glass chamber with argon gas that decreases the thermal dispersion to the outside of the home. It allows retaining the heat produced in winter at home, but does not allow it to isolate from the heat of the summer periods that affects the 3/4 of a home: the southwest side.

The selective glass (also called 4 seasons) is made with a magnetron treatment (a chemical-physical process that fixes on glass plates of silver ions) reflecting a high percentage of solar rays but continuing to operate from low emissivity In the winter.

It can be concluded that all the windows facing north - north / east - north / west (where there is little irradiation) may have low emissive glass with argon gas; While from east or south / east south-southwest, it is recommended to use selective glasses.
