Application

For use in a range of curtain walling applications.

Description

Forster thermfix vario is the profile system for curtain walls and sloped glazing in mullion-transom construction and dry glazing. The supporting static function of the system is assumed on the room side by arranged steel and stainless steel mullion and transom profiles which have narrow face widths of 45 or 60 mm.


The robust profiles with structural depths of 50 to 150 mm and wall thicknesses up to 4.5 mm permit constructions of large-surface dimensions and multi-storey curtain walls without any additional reinforcement.


Features and benefits:

  • Extremely slender face width, individual profile design and surface treatment.
  • Can be used over several storeys up to a height of 5000 mm.
  • Trouble-free assembly using mechanical T-joints.
  • Classification from CE-tests according to EN 13830.
  • Rain impermeability according to EN 12155: RE1200.


The forster thermfix vario system is divided into three main application sectors:

  • Security: vertical facades for fire resistance or bullet resistance (forster thermfix vario).
  • Energy efficiency: highly heat-insulated vertical facades at passive house Level phA (forster thermfix vario HI).
  • Pitched glazing (forster thermfix vario).
