Question:
Are Intumescent Seals required for fire rated steel doors ?
Answer:
Generally speaking, no, but the requirement is a function of the individual manufacturer’s listing. Intumescent products are typically used for a smoke and fire barrier on wood doors and are activated by heat. Given the basic properties of steel which expands when exposed to heat, seals would not typically be required.
