Do fire rated doors require the use of gaskets to seal the opening?
Typically, perimeter gasketing is not required on fire rated doors. However, doors in smoke and draft control areas may require it depending on the city, state, and/or county code. When required, make sure to use gasketing that is smoke/draft rated. As always, it is best to check with the local authority having jurisdiction to see what products are required in your area.
