The Norseal NOR810S is a rebated drop seal designed to automatically seal the bottom edge of acoustic timber doorsets against smoke and sound. The single-actuation mechanism drops a durable TPE gasket when the door closes, providing an effective barrier for gaps up to 12mm.
- Achieve rapid sign-off: Fully tested to BS 476: Part 22 and compliant with BS 8214 smoke requirements, giving you absolute confidence on fire door installations.
- Minimise installation errors: A substantial 150mm cutback allowance allows you to trim the 925mm seal down to size quickly and accurately on-site.
- Ensure lasting durability: Constructed with a robust aluminium carrier and a resilient TPE gasket that maintains its seal integrity over thousands of opening cycles.
This rebated seal is engineered specifically for timber doorsets and is suitable for use on most fire doors. It carries UL certification for BS 476: Part 22 fire resistance and strictly meets BS 8214 smoke requirements. Designed for straightforward, screw-fixed installation into a standard 12mm x 20mm rebate.
