CertainTeed. Covering 67 square feet per bag — up to 15% more than other products, the maker says — InsulSafe SP premium blowing wool requires contractors to handle less insulation per project. Designed for pneumatic installation in open attic areas, the formaldehyde-free material is made of white, unbonded virgin fiberglass, and won't rot, decay, or absorb moisture. It's GreenGuard certified as a low-emission material for indoor air quality. 800.233.8990. www.certainteed.com.
BioBased Insulation. For an eco-friendly spray foam solution, try BioBased 1701, a 1.7-pound-per-cubic-foot closed-cell material. The soybean-oil-based insulation emits no VOCs, CFCs, HCFCs, or formaldehyde, yet still behaves like petroleum-based plastic foam. Expanding to 100 times its original size during application, the material reaches an R-value of 4 per inch. 800.803.5189. www.biobased.net.
BaySystems. A new formulation of the popular ½-pound-per-cubic-foot density of BaySeal spray polyurethane foam improves ease of application by eliminating the need for agitation, the maker says. Compatible chemistry keeps the water-blown material in suspension without constant stirring. 800.221.3626. www.bsna.com.
Guardian.

As a dry system, there's no need to wait before installing drywall. 800.569.4262. www.guardianbp.com.
Icynene. To improve building envelope effectiveness, try Icynene spray foam insulation. The water-blown foam expands to 100 times its volume to fill cracks and crevices. Providing an R-value of 3.6 per inch of insulation, the material acts as an air barrier to minimize leakage. The material will not shrink, sag, settle, or lose its R-value over time, the maker says. 800.758.7325. www.icynene.com.
