Waterproofing Membranes, Weather tightness, and Airtightness

Protecting Buildings from the Elements: Waterproofing, Weathertightness, and Airtightness

Join us for an essential session where industry leaders unpack the critical intersections of building envelope performance. This conversation will delve into the science and strategy behind waterproofing, weathertightness, and airtightness, exploring how these three pillars work together to ensure healthier, more durable, and energy-efficient buildings.

Our expert speakers will share real-world case studies and the latest innovations shaping best practice—from mitigating moisture ingress to improving airtightness for thermal efficiency and occupant comfort. Whether you're designing for resilience, compliance, or long-term performance, this is your chance to gain actionable insights from those at the forefront of building science.

10:15am - 11.15am | Alex Holly | Omega Windows and Doors

Alex Holly will cover weather tightness and thermal performance, focusing on window and door details, proper installation, and key building code requirements.

Learning outcomes:

• Weather tightness with regard to thermal performance, covering basic weather tightness concepts and window and door specific details such as pressure equalization.
• Proper window installation, why it is important to a thermally resilient building and a step by step guide to a well installed window.
• A 101 on the window specific portions of the building code and the testing regimens that you may come across in reports or on site.

11.15am - 12.15pm | Chris Ross | Allco

Designing for Durability: The critical role of drainage in below-ground structures and waterproofing performance.

Chris Ross will explore the vital role of drainage for below-ground waterproofing systems, how drainage design influences the long-term performance of waterproofing and why it's essential for managing hydrostatic pressure.

We will also provide an update on Allco's CodeMark-certified products, discuss the implications of the Overseas Building Products Amendment Bill and how specifiers can stay compliant and informed.

Learning Outcomes:

• Understand the importance of drainage in below-ground design and how to apply it effectively.
• Gain clarity on hydrostatic pressure - what it is, how to design for it and when it is acceptable in a building design.
• Allco’s Codemark-certified products.
• Understand the impact of regulatory changes on overseas building products and the impact for waterproofing
