We all know about the necessity of fire doors in a fire safety system- but despite the extra two hours of resistance it can provide, fire door mastic is often overlooked
Fire door mastic is a sealant that is applied around the edges of fire doors to prevent the spread of fire and smoke.
Without it, fire doors are not guaranteed to perform at their optimum and prevent the spread of fire and smoke during an incident.
How do I identify which fire door mastic is best?
An FD120 rating guarantees the mastic is able to resist fire for up to 120 minutes- significantly more than lower rated fire door mastics.
Given how fast fires can overtake buildings, the extra time and protection offered by the FD120 rating could not only save assets, but lives.
Fire door longevity is another benefit of choosing the right sealant
Fire doors are exposed to a significant number of stresses and strain during their lifetimes- such as heat and smoke during a fire, as well as general exposure to the elements.
All these factors can cause the sealant around fire doors to deteriorate, which compromises their ability to prevent the spread of fire and smoke. FD120-rated fire door mastics are more resistent to this kind of wear and tear, providing a higher level of protection for longer.
Improved fire safety standards are often reflected in insurance premiums
Greater longevity in a fire safety system can mean reduced insurance costs for building owners.
High quality mastic is often recognised in insurance assessments to determine premium prices and taking steps to improve fire safety can lead to lower insurance premiums over time.
Certitek recommends that building owners consider investing in FD120-rated fire door mastic as part of their fire safety system to ensure the highest level of protection possible. You can find out more here.
