Experts in passive ventilation.

Welcome to VENT – New Zealand’s Leading Provider of Specialized Passive Ventilation Systems and Products now in Australia!

With over 12 years of experience in the industry, VENT takes great pride in being New Zealand’s foremost supplier of top-quality passive ventilation systems and products. Our unwavering dedication and expertise have earned us a strong reputation for delivering exceptional ventilation solutions.

Our journey began as a direct response to the misconceptions surrounding the well-known “Leaky Homes” crisis that affected New Zealand. We recognized that external moisture penetration and product failure were not the sole causes of this issue. The relentless pursuit of weather-tightness over the years had inadvertently compromised buildings’ ability to breathe, resulting in a lack of passive ventilation options. Consequently, internal moisture problems and related issues, such as toxic molds and structural decay, emerged.

In response to these challenges, VENT was established. We quickly became the go-to source for passive ventilation expertise, revolutionizing the industry and transforming the way buildings are designed and constructed. Through our tried, tested, and innovative solutions, we have played a crucial role in promoting the widespread acceptance of passive ventilation as an essential element for creating healthy and durable living environments throughout New Zealand.

Now, we are excited to expand our unparalleled knowledge and proven product range to Australia as VENT Systems. We fully understand the unique demands presented by Australia’s extreme climatic conditions and have tailored our products and systems to effectively meet these challenges.

In order to ensure the seamless integration of VENT Systems into the Australian market and to best serve the local building and construction industry, we have partnered with Proctor Group Australia. With their extensive experience servicing the Australian and New Zealand building and construction industry since 2005, we are confident in delivering exceptional results.

Under the joint brand of ProctorVent, our comprehensive portfolio includes thermal and acoustic insulation, precision-engineered geotextiles, passive ventilation, and vapor-permeable construction membranes, all specifically curated to meet local building codes and conditions.

Internal Moisture

Buildings in Australia are facing an increasing vulnerability to problems arising from excessive internal moisture. The Australian National Construction Code underwent amendments in 2019 and 2022, with a specific focus on constructing more energy-efficient buildings that prioritize airtightness and condensation management. While the advantages of creating tighter and more efficient homes are significant, there is also a risk of encountering issues related to excess moisture if the appropriate balance of mechanical and passive ventilation is not incorporated into the construction process. ProctorVent specializes in providing passive ventilation solutions for the non-habitable areas of buildings, such as roof and wall cavities, effectively managing moisture and mitigating associated risks.

To effectively address these risks, it is crucial to comprehend the factors contributing to the creation of moisture within buildings. Several variables influence a building’s susceptibility to problems, including its location, orientation, level of airtightness, occupants’ behaviour, design, the positioning of roof membranes/sarkings, and the utilization of mechanical and passive ventilation systems.

Examining some of the primary sources of internal moisture in more detail:

  • Occupancy behaviour: An average family of four produces approximately 30 litres of moisture daily. Within an airtight building envelope lacking adequate ventilation, this moisture can become trapped, particularly in poorly designed roof cavities.
  • Temperature variations: As temperature drops across the building envelope, condensation occurs when humid air reaches the dew point temperature on surfaces cooled to outdoor levels. This phenomenon is often unavoidable.
  • Moist building products: Materials like timber and concrete slabs contain moisture and require sufficient time to dry out. When the building envelope is sealed, moisture becomes trapped inside.

By incorporating ProctorVent’s proven, calculated, continuous, and unimpeded product combinations within the roof and wall cavities, moisture can be effectively managed, preventing the accumulation of harmful moulds, structural decay, and excessive heat build-up.
