Aralco VariaCoust
Trickle Ventilation System

The Aralco VariaCoust Trickle Ventilation System has an efficient thermal break and outstanding acoustic performance and can be used with timber, PVCu and Aluminium windows

The large airflows and impressive sound reduction capabilities of the Variacoust system result in the perfect balance between ventilation and insulation

A significant feature of the Variacoust system is the easily detachable inner profile (Air clip) which not only allows for a simple way of cleaning the product in its installed position but also acts as an insect mesh

All types of VariaCoust can be used in different ways:

  • Over the glass
  • Between two profiles, or
  • On the window, behind the wall cladding

Furthermore, each type of VariaCoust allows the thermal box to be placed in different positions
