Why are roof and wall penetrations needed?
Roof and wall penetrations are essential for routing ventilation ducts, pipes and cables through the building envelope. They enable fresh air intake and stale air exhaust while supporting the performance of the ventilation system. Because every penetration creates an opening in the building envelope, it must be properly sealed to prevent air leakage, water ingress and thermal bridges. Airtight and weatherproof connection systems help maintain energy efficiency, protect the building structure and support long-term system performance.
How can airtightness be maintained?
Maintaining airtightness starts with sealing every roof and wall penetration correctly. The Ubbink airtight seals help prevent uncontrolled air leakage while protecting the building envelope from moisture. By creating airtight connections, this solution reduce the risk of thermal bridges, support compliance with building regulations and contribute to the long-term performance of the ventilation system.
How do flashings work?
Roof flashings create a secure seal around roof penetrations, helping to protect the building against wind and water ingress while maintaining a weathertight connection. Combined with compatible collars and sealing components, they help prevent water ingress and ensure durable protection around the roof penetration, supporting the long-term performance of the ventilation system.
Ubbink roof flashings are available for pitched and flat roofs in a range of materials and colours to suit different roof types and installation requirements. Together with compatible collars, they provide a reliable solution for durable, weatherproof roof penetrations.
Supporting efficient ventilation
An efficient ventilation system relies on more than the ventilation unit and ductwork. Poorly sealed penetrations can lead to unwanted air leakage and may affect the overall performance of the installation.
Well-designed airtight and weatherproof solutions help to:
- Minimise uncontrolled air leakage.
- Protect ventilation penetrations from moisture.
- Support the performance of residential ventilation systems.
By protecting these critical connection points, the ventilation system can continue to perform as intended.
