Alutech ALT W72
ALT W72
Profile system with thermal break

The ALT W72 system is a universal integrated system that allows producing:

  • windows, doors and complex structures in modern energy-efficient buildings;
  • various kinds of structures that require increased thermal and sound insulation performance.

This system has mounting depth of 72 mm and a thermal break with width of 34 mm. Thermal and sound insulation performance is increased due to additional elements made of foam material. The possibility to use fillings up to 50 mm allows achieving excellent thermal and sound insulation properties.
