Enhance Comfort and Health in Buildings with DriSpace Passive Ventilation Systems

Ventilation pathways

Managing internal moisture in buildings and roof cavities is crucial for creating a healthy, comfortable, and energy-efficient home. Poor indoor air quality contributes to respiratory illnesses and can affect material durability, especially in roof spaces. To address these issues, proper ventilation pathways within the roof cavity are essential when constructing a home that prioritises health and energy efficiency.

According to the MRM 10.10 Code of Practice, eave-to-ridge ventilation is the ideal pathway. Warm air naturally rises, but it has limited lateral movement. DriSpace offers passive ventilation solutions for all roof pitches, ensuring sufficient airflow from eave to ridge while maintaining an airtight, breathable, and energy-efficient building envelope.

DriSpace internal moisture management solutions

DriSpace’s Internal Moisture Management Design Guide provides tailored passive ventilation and air barrier solutions for various roof pitches. By integrating passive ventilation components with DriSpace underlays, proper airflow is maintained without compromising insulation or energy efficiency. These system solutions apply to skillion roofs (both pitched and mono-pitched), trussed roofs of all degrees, and sarked roofs.

Managing dew point condensation

Dew point condensation is a common issue, especially when steel long run roofing is directly fixed with underlays. If left unaddressed, it can lead to significant costs. As highlighted in MRM Code of Practice 10.11, condensation forming on the underside of the roof typically tracks down the underlay only as far as the next purlin, where it becomes trapped and absorbed. Consider installing VB10 on top of the underlay to manage dew point condensation cost-effectively. This creates an essential ventilation and drainage pathway and extends the life and effectiveness of the vapour permeable underlay.

No maintenance and operational costs

Passive ventilation operates year-round without moving parts or energy consumption. The 4mm vents effectively prevent nesting insects from entering. This approach not only enhances building durability but also contributes to overall affordability by minimising maintenance and repair costs over time.

Enhancing roof space efficiency with ProctorPassive SmartVap

To enhance the performance of your building enclosure, consider installing ProctorPassive SmartVap. This solution ensures that the ceiling remains air and vapour tight, preventing conditioned and moisture-laden air from entering the roof space. By minimising interstitial condensation caused by high moisture loads in rooms, SmartVap contributes to a healthier indoor environment. When installed as a continuous layer, SmartVap effectively forms an airtight barrier. This enhances the efficacy of ventilation systems and improves the overall thermal efficiency of the building enclosure.
