Healthy Spaces with Vent: The Hingaia Peninsula School Project.

A four product combination from Vent creates passive ventilation for an extension at Hingaia Peninsula School in Auckland.

Project Brief:

Hingaia Peninsula School in Karaka, Auckland built a large new extension which featured a combination of classrooms and shared spaces. To mitigate the risk of internal moisture, the Ministry of Education specified a Vent passive ventilation system for the extension’s long run skillion roof.

Schools are Recognising the Need for Passive Ventilation.

Vent has been involved in a number of school rebuilds, extensions and reclads over the past couple of years.
“The beauty of this project was that it was a complete four product combination,” explains commercial manager James Johnston.

“It’s the perfect system to create passive ventilation through the skillion roof cavity. It allows the whole extension to breath and reduces damaging structural mould and moisture.”

Breathable buildings ensure longevity. School buildings made to last mean more funding for other parts of the school in future years, rather than expensive remedial work caused by moisture build up.

Product Breakdown

The installed system features the following

G2500 Over Fascia Vent

This is to ensure our recommended 25,000mm2 free flow of air per l/m can enter the roof cavity for skillion roof designs.

VB20 Vented Batten

The vented battens on top of the purlins ensure airflow is unimpeded through the roof cavity. While ensuring structurally the battens can withstand MRM point load requirements.

RV10P Ridge Vent

The ridge vent allows natural convection of warm moist air to escape the cavity. Where there is wind movement, the ridge vent also creates negative pressure to draw airflow through the roof cavity.

G1275 Eaves Comb Filler

While not a ventilation component, the eaves comb filler contributes by preventing any ingress of birds nesting in the roof cavity while still allowing airflow below roof cladding and above roof underlay.

The combination of products work together to ensure calculated airflow of 25,000 mm2 per linear metre of air passing through the roof cavity reducing the risk of structural moisture build up and dangerous mould.

Installation Partners

Installation was completed by Reel Roofing, who took to installing the Vent products with ease.

“It was a perfect specification and application from start to finish,” says Johnston.

Johnston is particularly pleased with the use of the full system of products as it will protect the building and occupants for years to come.

”It will prevent structural decay of building products and prevent the build-up of harmful moulds that could start to grow and fester in the roof cavity due to moisture. As a result, it contributes to creating a healthy environment for the kids who will be in the building every day.”

Why install Vent in extensions and renovations?

Vent’s passive ventilation system is a worthwhile investment in school building projects as it will minimise future maintenance and ensure the longevity of school extensions.

“Designed right and applied correctly, we know this roof is going to stand the test of time,” says Johnston.
