Wisconsin Uniform Dwelling Code deep dive: air sealing

Air sealing makes a big impact on a home’s durability and comfort. Why should you inspect for UDC air sealing requirements or know if your approach to air sealing delivers high quality? In this webinar, you’ll become thoroughly familiar with the UDC single family air sealing requirements. Proper air sealing and insulation work together to deliver energy efficiency. This course gives you a close look at the UDC’s air sealing techniques so that you know you’re building to high standards. We’ll show you the “why” behind the code requirement. We’ll also walk you through what materials to use, where to use them, and how to install them to meet the code requirements.

As a result of this webinar, you will be able to: 

  • Explain why proper air sealing has a big impact on durability, comfort, and energy efficiency. 
  • List the different areas where air sealing is required by the UDC code. 
  • Discern between various materials and installation techniques to achieve code compliance. 
  • Review two ways inspectors look for code compliance – visual inspections or blower door testing, so that you know what to expect. 

Who should view?
Code inspectors, builders, remodelers, architects, building performance consultants, designers, educators, government officials, home inspectors, students of construction programs, utility representatives, insulators and air sealers, and anyone interested in quality residential construction practices.
