Key Points:
  • A 30 minute fire-resistance seal.
  • BS476 part 22.
  • A fire seal from Sealmaster. 
IF30 is the basic intumescent fire seal in the Sealmaster range. It is used where primary protection is needed, to single and double leaves and single and double acting doorsets, and is specified for use on FD30 fire doors. 

The seal consists of an extruded aluminium alloy profile with a single reservoir of Sealmaster Intumescent material.

As the fire develops and reaches the IF30 seal, the Intumescent material foams, swells and fills the gaps between the door and the frame. Since the foam remains soft during the period of the Intumescent action, it does not prevent the door from being opened by firefighters and the copious reserves ensure that the gap will be re-sealed should the door distort for any reason. 

IF30 Intumescent Fire Seal has been tested by TRADA. A 30 minute fire-resistance rating was achieved, when used in conjunction with a 30 minute fire door. Copies of the test reports are available on request. IF30 fire seals have been tested and approved by Certifire to conform to BS476 part 22. This is the most demanding 3rd party certification scheme in the industry.

We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on Tel: +(0)1329 841416 or email


All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 Code of Practice for the Installation and Inspection of Fire Stopping.


It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
