DEVL 6 - Best Practices: Insulating Closed Cavity Walls

Thursday, February 05, 2009  ·  1:20 PM - 2:50 PM

Installing insulation in closed cavities poses challenges of access, coverage, and settling. Air movement through insulation can undermine its effectiveness. Explore best practices for achieving and ensuring cost effectiveness and impact. Learn how products differ, what’s the best insulation machine, the best delivery system, and if a tube is required. Applications for dense pack cellulose, mineral wool, fiberglass, and two-part foam will be discussed.

By attending this session, participants will

1. Learn the latest techniques for installing insulation in closed cavities, including dense pack and two-part foam
2. Understand the importance of proper insulation density, installation techniques, machine capacity, and machine settings for minimizing voids, settling, and air movement
3. Explore methods for verifying the proper installation of wall insulation, including core sampling, bag counting, and digit testing
