FAQ: Door Construction Materials
Why do doors need intumescent materials?
Building Codes require fire door assemblies to meet the requirements of UL 10C and UBC 7-2-97. To meet these requirements, Category A doors will need intumescent within the construction. Category B doors will require a surface applied intumescent gasket. Please refer to our sections on Door Construction Materials and Gaskets for Fire Doors Assemblies for the Lorient products that will help meet these requirements.
