Description

Ideal for use in soil and vent applications and for mechanical ventilation or natural/passive systems, this Twin Wall OFT4 Flat Roof Vent Terminal from Ubbink features a flange suitable for use with a PVC roof covering. With a unique low air resistance cowl, it has a pressure/airflow resistance of less than 1.0 Pascal at 225m³/h.

The pipework above the roofline is twin-walled and integrates a built-in condensation drain. The stack pipe has an integral collar and separate aluminium flange for use with both asphalt and felt. This Ubbink flat roof vent terminal allows termination through a flat roof duct with a 166mm diameter. The stack cap is secured mechanically for more reliability when fitting in extreme weather conditions. However, it is detachable for servicing purposes.

Questions & Answers

Question:

Will this terminal work with a flat fibreglass roof

Answer:

This has an Aluminium Flange, which Fibreglass will bond to if you score/scuff it up first. You would need to put the vent in then dress back over the Flange in Fibreglass to make it watertight.
