TM 77HI system

The TM 77HI system is a safe and innovative solution to achieve excellent thermal insulation, acoustic, wind and water protection and security parameters.

Thanks to the use of spacers between the aluminium profiles, excellent thermal insulation values have been obtained.

The role of thermal insulation is fulfilled by chamber insulators dedicated to the system, together with the filling.

Advantages of the system

  • possibility of heating costs reduction,

  • possibility of creating large-surface structures with mfromern arrangement of façades and interiors,

  • easy to match with fittings elements and control elements,

  • possibility of creating mfromern structures of various shapes and

  • excellent value of the heat transfer coefficient at the Uf level from 0,8W/m²K,

  • possibility of making balcony door with low threshold,

  • divided thermal separators prevent sashes/leaves from bending under the influence of high temperature,

  • possibility of making an all-glass corner.
