Sustainable Land Development Today - January 2008 - (Page 59) Products & Services Showcase CONSTRUCTION MATERIALS: Fire Resistant Attic Vent from Brandguard TECHNOLOGY: Topcon GR-3 now with CDMA cellular modem option Brandguard Vents has developed a series of newly designed vent products that prevent fire embers from entering the house. The baffle material acts as a heat sink, virtually eliminating the threat of fire embers entering through a structure’s vent openings. The baffle design changes the flow of air several times, creating an effective heat trap, preventing damage from radiant and direct heat sources. The design has comparable net-free vent area and allows for sufficient exchange of moist air, thus preventing mold issues. Brandguard Vents make Dormer, Round, Access, Soffit and Gable End Vents that are applicable for most roof types.
