When choosing a window, it is important to pay attention to the glass. Glass surfaces occupy more than 70% of windows, and that is why it is essential to choose the appropriate glass.

There are several types of glass, and below you can read more about special types, which are often used, and which with their characteristics improve your windows and doors.

Insulating glass

This glass is composed of two or more glass surfaces, which are separated from each other by one or more hermetically sealed interspaces. The space between the glass surfaces can be filled with air or some of the inert gases if we want to achieve better thermal insulation.

The most significant improvement in terms of reducing heat emissivity can be reached by using low- emissivity glass– LOW-E. The low emissivity glass characterized by a particularly selective layer of oxide molecules placed on the surface of the glass that reflects only thermal radiation. Less heat is lost through low emissivity glass because energy returns to the space it comes from. By combining low emissivity (LOW-E) glasses and inert gases in the iso-glass composition, we achieve top performance. Such glass not only reduces heating costs but is also indirectly involved in protecting the environment by reducing the total amount of energy required and thus reducing the emission of harmful gases into the atmosphere.

Safety glass

Safety glass can be tempered and laminated glass. It is called safety glass because it does not create sharp edges when broken, which could injure you.

Laminated glass (lamistal)

Safety laminated glass is an excellent choice for safety glazing. This glass is composed of two or more plates of glass interconnected by one or more high-tensile PVB films. This foil can be colorless or colored, with improved sound protection and a high degree of UV protection. When broken, the safety laminated glass does not break into small pieces, but remains bound in the central foil.

This glass is used for glass positions with large spans, and for glazing windows and doors of rooms where there is a danger of breaking with sharp objects, burglary and firearms.

Tempered glass


Safety tempered glass is obtained by heating the glass up to the plastic limit to approximately 600˚C, after which it is rapidly cooled by air. In this process, the glass acquires high mechanical and thermal resistance. When broken, it disintegrates into small grains with blunt edges and thus protects against injuries.

The use of this glass is in the glazing of exterior and interior walls of buildings (facades), safety fences, doors, terraces, balconies, conservatories, telephone booths, showers, ships as well as in the manufacture of insulating glass.
