New Videos: Sealing Ducts and Installing Dense-Packed Cellulose
GBA presents two new videos, both recorded at NESEA's Building Energy 13 conference in Boston
GBAGreenBuildingAdvisor.com has released two new videos: one on installing dense-packed cellulose in stud cavities, and the other on sealing duct seams with mastic.
Both videos were recorded in March 2013 at NESEANorth East Sustainable Energy Association. A regional membership organization promoting sustainable energy solutions. 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.
How to install dense-packed cellulose
The cellulose video features Bill Hulstrunk and Chris White, two experts from National Fiber, a manufacturer of cellulose insulationThermal insulation made from recycled newspaper or other wastepaper; often treated with borates for fire and insect protection.. Among the questions answered in the video:
- What tool is best for cutting InsulWeb fabric — scissors or a utility knife?
- What's the maximum recommended spacing between staples?
- What are the minimum specs for an air compressor used to power a pneumatic stapler?
- How can you tell whether damp-spray cellulose was installed with too much water?
- If studs are spaced 24 inches on center, is it still possible to install cellulose insulation behind InsulWeb?
How to seal duct seams
The duct sealing video features Eric Wilder and Will D’Arrigo, two experts from the Conservation Services Group. Among the questions answered in the video:
- Are any tapes durable enough for duct sealing?
- When should I use mastic, and when should I use tape?
- When should mastic be applied with a paint brush, and when should it be applied with a trowel?
- 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?
