Understanding ULPage 8 – Blanket Insulation18. Blanket InsulationUnless specifically described in a design, the additionof insulation in the concealed space between theceiling membrane and the floor or roof structuremay reduce the hourly rating of an assembly bycausing premature disruption of the ceilingmembrane and/or higher temperatures on structuralcomponents under fire exposure conditions.
Page 10 – Wall and Partition AssembliesUnderstanding UL• The ratings for walls and partitions apply when either face of theassembly is exposed to the fire unless indicated otherwise on aspecific Design.• The hourly rating of a load bearing assembly also applies to the sameassembly when it is used as a non-load bearing assembly.• The size of studs are minimum unless otherwise stated in a Design.• The spacing of studs is a maximum unless otherwise stated in aDesign.• Spacing between een parallel rows of studs are minimums ms unlessotherwise stated in the individual designs.• Gypsum board thicknesses specified in specific designs areminimums. i Greater thicknesses of gypsum board are permitted aslong as the fastener length is increased to provide penetrationinto framing that is equal to or greater than that achieved with thespecified gypsum board thickness and fasteners.
