Building Energy Efficiency in Skillion Roofs.
Create a healthy and energy efficient home by complementing your insulation with a passive Vent system.Skillion roofs create a fantastic sense of space in a new build and an elevated, modern design, but they can be prone to moisture build up thanks to the minimal gap...
Case Study: Mitigating Dew Point Condensation with Roof Ventilation
Concerned about dew point moisture in your new build? Our case study explains how Vent roof ventilation can simply separate roofing and underlay for a healthier build.
E2/AS1 Compliance
Our article explains why passive ventilation is important to ensure you’re compliant with moisture management E2/AS1 (3.5, 3.6) and E3.2.
Installing ventilation saves you money and protects your truss roof build
One major building block of a healthy home that is sometimes forgotten is passive roof space ventilation. Evidence has shown that without adding ventilation to our builds, condensation and mould build up is becoming a secondary concern
Why do you need ventilation? The crucial role of passive ventilation in your next project
Homes are more weathertight than ever. This is great news for our overall health and energy efficiency. But homes without airflow create an alarming moisture problem tightly regulated in other parts of the world but not in New Zealand.
