The company says it has expanded its hvac/mechanical fiberglass insulation products brochure to include the enhancement features on its ToughGard™ duct liner product. The user-friendly, 24-page, full-color brochure now includes data on ToughGard duct liner with enhanced surface, which the company says repels water up to 40% better than standard liners and provides “superior protection against moisture absorption, while retaining the acoustical performance of the liner.” — CertainTeed Valley Forge, PA
