As building envelope leakage requirements get stricter, we are on a mission to make meeting them easier.
Along with a team of UC Davis building scientists, we have dedicated over 5 years to research and development, determined to make envelope sealing quick, easy, and affordable.
The result, AeroBarrier.
Below you will find some tables and resources that will help you understand different leakage requirements, all of which AeroBarrier can help you achieve. If you’d like to learn more about how AeroBarrier can help you achieve any level of envelope tightness required for your next project you can contact us by clicking here.
