The Extension Sleeve is designed to be used in conjunction with the Telescopic Underfloor Vent. Each extension sleeve allows the vent to vertically reach a further two brick courses and can also be fitted horizontally to the base of the Telescopic Underfloor Vent by using a Rear Extension Adaptor.
Telescopic underfloor vents are used to create a clear airflow channel into voids below suspended timber and block and beam floors. The telescopic feature means the units are able to adjust the ventilation channel vertically from within the cavity.
