Biyou Intumescent Fire Strip product is based on the chemistry of expandable graphite. It is flexible and thus easy to install and comes with self-adhesive backing. Our intumescent fire strip is designed to expand to more than 30 times it’s installation size to prevent air circulation and the escape of hot gases and smoke between doors, frames and other potential gaps where fire resistance is required. In addition ourfire strip ensures smoke and toxic gas reduction.
