Description

The Invisivent 430 is Mighton’s registered design flush-fitting trickle vent, built to provide simple, controllable background ventilation for condensation control while sitting flush and unobtrusive on the frame. It’s suitable for use with timber, uPVC or aluminium windows and doors, so the same vent covers the job whatever material you’re specifying for. Because it ventilates the room without needing the window itself open, it helps satisfy Building Regulations Approved Document F while keeping the window closed and secure — including while the property is empty. Tested to EN13141-1:2019 and manufactured from UV stabilised ABS, it’s built to hold its colour and finish through years of outdoor exposure.
