Thermal Bypass Workshop: Understand the Risks and Learn from Case Studies – Online

Event Details

A two-hour session on thermal bypass with UK expert Mark Siddall.

Known as thermal bypass, air movement across, within and behind insulation increases heat loss, causes discomfort and enables mould growth. With the correct knowledge and skills, both in practice and onsite, failures in design and construction can be avoided and deliver buildings that perform as predicted.

Join us and author Mark Siddall for a live online workshop about his report, Thermal Bypass Risks Technical Review.

The workshop will explore how thermal bypass risks can be addressed, and  performance gaps avoided, by adopting good design and construction practices. In the workshop Mark, Principal at Mark Siddall Consulting, will:

  • review existing knowledge and understanding about the impact of thermal bypass
  • showcase practical examples of best practice, and 
  • give you the chance to hone your design skills so that you can eliminate thermal bypass risks
