FireSealsDirect works with a number of industry-leading suppliers, and has a long-standing relationship with Norseal. They have a worldwide reputation as a leading manufacturer, and for many of their products, hold third party approval under internationally recognised schemes to the highest standards including IFC and Certifire. 

Intumescent strips, or fire door strips, are fitted to the door, and, when exposed to extreme heat, expand to close any gaps or edges that may leave the fire door vulnerable to fire and smoke spread. The Norseal Extended Brush range of Intumescent Strip is designed for doors that can not adhere to the 3-4mm gap as advised by The British Standards.  Often, we see these types of extended brush strips being used in listed buildings. 


PLEASE NOTE: This product does not hold Certifier Status or Data Sheets.
