The Difference Between Intumescent Sealant and Fire-rated Foam

A common mistake we often see in the fire safety industry is for fire-rated foam to be used in situations where intumescent sealant is better suited.

While fire-rated foam expands on application, it sets hard and will not expand further and seal up a hole when a fire breaks out.

Intumescent sealant, on the other hand, does not expand when applied, and only swells up when a fire has broken out and it reaches a certain temperature. In this circumstance, the sealant will then expand and seal a hole to reinstate a wall or door’s fire containment properties.

In this video we outline the differences between both fire-rated foam and intumescent sealant, discussing their use and application to help you find the right product for your needs.

Make sure you read the associated technical datasheets when selecting a product as some have a wide range of test applications and others are more limited.
