Description

Approved Document F dictates the following requirement:

For dwellings with multiple floors:

• Habitable rooms and kitchens must have a minimum EA of 8000mm2
• Bathrooms must have a minimum EA of 4000mm2

For single storey dwellings (e.g. flats):

• Habitable rooms and kitchens must have a minimum EA of 10000mm2
• Bathrooms must have a minimum EA of 4000mm2

You can use a single vent or multiple vents to achieve the required EA

In addition, the trickle vents must be controllable by the occupant. The SlotVent range is particularly flexible with 30°, 60° and 90° tilt modes to adjust the airflow. Externally, they feature a curved hood for optimum weather sealing.

In high noise areas, or where customers are particularly concerned about draughts, there is a noise reduction version available in 5000EA, which comes with a foam gasket on the internal section.
