Periscope Telescopic Wall Underfloor Vent 9" x 3"
The telescopic underfloor vents provide a clear airflow passage through the wall into the voids below suspended concrete and timber floors. The telescopic feature enables the product to adjust the ventilation channel vertically within the cavity, helping to meet the Building Regulations Part C requirement for ventilated floors.
The Telescopic Underfloor Void Ventilator is designed to provide a clear airflow passage to the void underneath a suspended floor.
The telescopic feature enables the ventilator to adjust vertically between three and five brick courses.
