Dura-vent
Dura-vent is a great alternative to through frame trickle ventilation for all New Build and Commercial applications. The overhead vent allows maximum air flow without compromising the window frame integrity. The trickle vent is fitted to the underside of the profile, eliminating any obstruction from internal plasterboard finishes, ensuring optimal performance at all times. Furthermore, the sleek external profile helps to conceal the integrated flat grill and gives the installed frame a great finish.
