The G965 Dual Extended Telescopic Underfloor Void Ventilator is designed to provide a clear airflow passage to void beneath an insulated suspended floor. The G965 offers a vertical telescopic adjustment of between 5 and 8 brick courses without the need for an extension sleeve. The horizontal outlet is long enough to bridge through an overall wall thickness of 350mm without the need for an additional extension. The front aperture of the G965 is designed for use with a G930 Combination Airbrick or it can be used in conjunction with a traditional clay airbrick, although this would reduce the overall airflow through the system.
