Fire Blocking Expanding Polyurethane Foam Sealant More Cost-Effective Than Standard Fiberglass and Caulks
RectorSeal®, Houston, a leading manufacturer of quality HVAC/R and plumbing tools and accessories, and a wholly-owned subsidiary of CSW Industrials, Inc. [NASDAQ: CSWI], has introduced Draft-Block™ Orange, a fire blocking expanding polyurethane foam sealant for use by trade professionals across North America.
Designed for Type V residential construction, Draft-Block Orange is an excellent filler that expands up to three times to fill, bond, and insulate a wide assortment of applications. As a low pressure, one-component product, it adheres readily to wood, glass, metal, tile, concrete, and most plastics. Beyond its fire blocking benefits, Draft-Block Orange helps to reduce sound transmission.
Available in a 12-ounce aerosol can, Draft-Block Orange fills voids, cracks, crevices, and small cavities on flat and irregular surfaces. After curing, Draft-Block Orange is an odorless, non-corrosive, non-reactive inert substance.
As indicated in the product name, its orange color makes it easily identifiable during use. As a polyurethane foam, Draft-Block Orange is completely dielectric and contains no urea or formaldehyde. When properly applied, Draft-Block Orange dries tack-free in approximately 5 minutes. It is cuttable within 1 hour and fully cured within 12-24 hours. When fully cured, Draft-Block Orange is resistant to water and outdoor exposure. The product adheres to UL evaluation report R40378-01 and achieves an ASTM E84 rating.
Draft-Block Orange offers outstanding performance when used in voids around plumbing and utility penetrations to stop drafts and prevent the intrusion of insects and other pests. Additional use includes sealing around windows, air conditioners, ducts, and vents and providing energy-saving features in heating and cooling installations. Draft-Block Orange can help seal voids in siding, door jams, foundations, and concrete joints.
