Aluminum window colors

The full range of RAL colors is available in a sample list.

Basic colors

RAL 9016 White
RAL 9006
RAL 8019
RAL palette color

The colors presented are just a visualization and may be different from the actual colors.

Corner windows manufactured in the DA-77 system are primarily products used in modern buildings, where the visual effect meets the expectations of current architectural designs.

The shape of the building acquires a light and very modern character. In addition to their visual appeal, they provide free access of light to the buildings in which they are installed. The glass surface is larger, allowing up to 20% more sunlight to enter the interior (depending on the size of the window).

What sets the DA-77 EI range apart in the fire safety standard?

 

The construction is based on the DA-77 system, thanks to which it is characterized by high thermal and sound insulation and water and airtightness. Therefore, the DA-77 EI system combines the advantages of a classic window system with the properties of fireproof partitions.

The buildings meet all the requirements of current regulations and standards, especially those concerning energy savings and environmental protection, while ensuring adequate fire safety. The system is classified as non-fire spreading (NRO). 

  • Profiles with three-chamber construction, where the central part is the insulation chamber between the thermal breaks with a width of 43 or 42 mm
  • Fire insulation elements in the internal chambers of aluminum sections and special accessories and materials functioning in the space between the aluminum sections and the glass
  • A wide range of glass thicknesses allows the use of various types of insulating glass units, including double-chambered sets
  • Fittings used in DA-77 EI are standard in anti-burglary RC2 class
