The refined appearance

For a modern minimalistic appearance of joinery MasterLine 8 offers the Hidden Vent profile system. With Hidden Vent profiles the vents are covered by the outer frames and transoms, which allows for a concealed install of the window elements behind the window reveal. Within composed elements opening elements cannot be distinguished from fixed panes, giving facades a refined look.


MasterLine 8 Hidden Vent elements are available on three insulation levels: ‘standard’, HI and HI+ and with two different glazing options for the vents. The first option is with a small concealed glazing bead on the exterior side of the vent and a robust inner half scale to allow for large dimensions and weights. The second option it with an internal glazing bead to allow for easy installation and glazing of the elements.
