Thermal Brake VL-61

VL-61 design allows us to extend the existing frame, with a thermally insulated chamber in which we can add a selection among a shading, security, or rolling shutters system.


  • VL-61 is manufactured from thermally insulated profiles, providing high thermal insulation of the doors and windows.
  • An elastic diaphragm is placed along the versatile VL-61 and thus achieving improved sound insulation.
  • Is designed in such a way to offer quick and easy access inside, without requiring special tools.
  • Can improve aesthetically and offer thermally insulated steel hollow sections that are often used for static support of large frames in a building.
