These are glass insulating units made up of glass with thermal insulation and solar control performances, which can be done in the same glass (selective glass) or in different glass that makes up the insulating glass unit. 

The main advantage of these compositions is that they bring the advantages of solar control and thermal insulation together. If this composition is used with selective glass then this gives us more flexibility when forming the glazing in the interior glass with laminates, acoustic laminates…In the case of using two panes of glass then the solar control would go in the exterior and the thermal insulation in the interior. The cost savings for heating and cooling the houses compensates the extra cost implied in this type of glazing in comparison to conventional glazing.

In all types of glazed enclosing. This glass will end up prevailing in the market due to great benefits offered.
