It is simple to use: The kerb is equipped with 4 x 4 fixed blades (as standard) which allow the free circulation of air, and a constant exchange of the air inside the buildings (ventilation per blade: 0.0625m2 / linear metre). The inner side of the kerb is equipped as standard with a 10mm anti-pest mesh. An optional insect screen is available.
The Permanent Ventilation Kerb is ideal for new buildings and is also available as an adapter plate for refurbishment.
