VENT Ridge Vents Now Even Easier to Specify and In

Experts in passive ventilation systems, VENT are dedicated to providing high-performance ventilation systems that are easy to specify and install. In an update aimed at streamlining the specification and installation of their passive ventilation systems, VENT is reducing the width of their RV10P and RV10DT ridge vents from 2021. The new sizing will ensure that standard ridge cappings of 200mm will accommodate the ridge vents — eliminating the current need for ridge cappings to be extended.

The change in sizing also comes with a minor adjustment to compatibility:

The RV10P Ridge Vent will be compatible with trough sizes up to 34mm
The RV10DT Deep Trough Ridge Vent will be compatible with trough sizes from 34mm to 48mm.

VENT is also condensing their product range as part of the update. They will stop supplying the AB20 and AB20DT Apron Vents which were specifically designed to ventilate abutments and barge details. Instead, by simply cutting the newly designed and sized ridge vents in half, installers can create apron vents capable of providing the same level of ventilation for abutment and barge details. In technical details, VENT will refer to these apron vents as RV10P Half or RV10DT Half.

While the sizing has changed, VENT’s ridge vents still provide the same trusted passive ventilation performance, ensuring airflow rates of 8,000mm² per linear metre. The vents are a key component of VENT’s passive ventilation systems, providing passive airflow and releasing hot air from roof voids to eliminate condensation.

And installers can rest assured that the RV10P and RV10DT ridge vents are still as easy to install as the original design — only now with the added benefit of being fully compatible with standard 200mm ridge cappings.

The new size ridge vents will be available from January 2021 from VENT’s NZ distributor, DriStud.

To request a PTS or DWG, please contact Alina from VENT on [email protected] or Jinny from DriStud on [email protected]. VENT will also update all documentation online as soon as the new vent sizes are available.
