Fitting Options
Espagnolette, standard
The espagnolette handle is standard in our opening functions – other handles are available at an extra cost.
Matt-chrome surface finish.
Ventilation position
The striking plate is provided with two punchings.
The inner punching is used to close the window completely.
The outer punching allows you to set the window / casement door in the ventilation position (5mm).
Restrictor with ventilation position
Limits opening of the window to 5-10cm.
The restrictor can be locked in the ventilation position. Push the red locking plate until a click is heard.
In side-hinged and side-guided opening functions the restrictor is installed at the jamb.
In tophung fully reversible function, it is installed at the cill.
Not available for sliding casement doors and 2-leaf casement doors.
Grey, corrosion-proof zinc-aluminium surface finish.
Please watch the video How to operate the opening restrictor with ventilation position.
Automatic cleaning catch
The cleaning catch(es) are activated automatically when the sash is turned to the cleaning position.
Double glazed windows will only have one catch.
Most triple glazed windows will have two catches due to the glass weight, however small triple glazed only will have one catch.
Safety bar
Sashes, which are higher than 885mm, have a small safety bar installed at the jamb, which should be clicked onto the sash for greater stability during cleaning the reversed external side of the window.

2. In combination with espagnolette handles, the circular catch handle ensures wind and water tightness for tall topguided and reversible windows.

Acoustic trickle vent
Efficient glazing is fundamental to noise control, and fresh air is essential to our wellbeing.
The new acoustic vent is designed to provide both fresh air and noise control in buildings when combined with VELFAC SOUND windows.
Features
The vent achieves a sound reduction value of Dn,e,w (C; Ctr) = 40 (-1; -2) dB.
The acoustic vent is machined into a timber packer, which will be installed and sealed on site.
The external aluminium profile is polyester-powder coated in the same colour as the window sashes, allowing an elegant integration with windows and facade.
The acoustic vent, which is visible from inside, comes in RAL 9010.
