TM 77EI 30 system

A system of three-chamber thermally insulated aluminium profiles designed for the construction of opening windows with fireproof partition properties.

The design of the solution is based on the popular Yawal TM 77N system. The product is dedicated to public buildings and single-family houses.

It combines two important functional features: excellent thermal insulation and fire resistance at the EI 30 level achieved through the use of appropriate glass and cooling elements inside the aluminium profiles.

Advantages of the system

  • an excellent thermal properties thanks to a three-chamber constructionwith the PIR insert in the middle and GKF insert from the inside,

  • an extend range of fire-proof glass panes which can be used, starting at frameless glass panes to double-chamber units,

  • possibility of using fittings in class RC2 and RC3,

  • possibility of constructing opening windows with transom windows and sidelights,

  • the system connects two functionalities: an excellent thermal insulation and fire resistance at the EI 30 level,

  • Use of ventilators, exclusively in the Yawal offer
  • possibility of combination with other Yawal systems.
