Concealed Trickle Vents

Aluminium bifold doors now with concealed trickle ventilation

Most folding door installations require trickle ventilators to be fitted to comply with building regulation requirements and these are usually fitted to a frame extender that is fitted between the lintel and the top of the outer frame or on some systems the trickle vents can be fitted to the tops of the door sashes.  

However, wherever they are fitted they do spoil the slim lines and aesthetics of any folding door so we have developed a unique and exclusive frame extender that conceals trickle vents from view on our Visofold aluminium bifold doors.  The design incorporates an angled weather bar that enhances weather protection at the top of the door and allows trickle ventilation to be fully concealed from view.

Available now and at no additional cost our fully integrated trickle vent head extension means that we no longer fit ugly face fixed trickle vents that spoil the look of your new aluminium folding door.
