Thermafiber has released a light fixture protection kit for the commercial building market. FixtureShield kits are made from rigid Thermafiber mineral wool boards. The new, patented light-weight design reduces installation time, offers energy-saving R-value and improved sound control. FixtureShield is UL approved and listed in several fire-rated floor/ceiling and roof/ceiling assemblies. Fire protection is a critical element for ceilings in both the 2009 and 2012 versions of the IBC code. Any penetration of a fire-rated ceiling must be protected so that the entire ceiling assembly will not be compromised.
