NESEA is committed to advancing three core elements: sustainable solutions, proven results and cutting-edge development in the field. States included in this region stretch from Maine to Maryland. www.nesea.org's Building Energy 13 conference in Boston on March 6, 2013, duct sealing experts Eric Wilder and Will D’Arrigo explain how to seal leaks in duct seams and how to conduct a duct leakage test.
Among the questions answered in this video:
- Are any tapes durable enough for duct sealing?
- When should I use mastic, and when should I use tape?
- What kind of mastic should I use?
- When should mastic be applied with a paint brush, and when should it be applied with a trowel?
- Are there any changes to code requirements for duct sealing on the horizon?
- Can I use a fogTo fog a room or building is to use a fog machine during a blower door test, revealing locations of air leaks where the fog escapes. The fogging material is usually a glycol-based solution, completely non-toxic. machine for duct leakage testing?
- Are ducts tested at 25 pascals or 50 pascals?
