Gaskets are required for doors to pass a smoke and draft control test. The requirement for a gasket also includes the meeting edges of a pair of doors. The gaskets used in a smoke and draft control assembly must be fire rated and be listed for use in a smoke and draft control assembly. A bottom seal is not required for smoke and draft control assemblies. The UBC code calls for a tight fitting assembly that meets the requirements of UBC 7.2 Part II. The UBC includes the following statement: “Smoke and draft control door assemblies shall be provided with a gasket installed so as to provide a seal where the door meets the stop on both sides and across the top.”
