RPBHB Series Intumescent Pad
For Marine Electrical Switch and Socket Boxes

Fire Door Strips are specialized seals installed on fire doors to prevent the passage of smoke, flames, and toxic gases during a fire, enhancing the door’s ability to compartmentalize and contain the spread of fire.

Over-painting of fire door strips should not compromise performance in a fire situation – however, do not suggest paint over fire door strips as this will certainly compromise the sealing containment performance and use life. If the intumescent strips on fire doors has already been painted over, you will need to replace it. Our seals are available in a range of colours, plus woodgrain and metallic finishes, so over-painting should not be necessary.

In the event of a serious fire, fire doors are one of the most important components in ensuring safe exit, containing the fire and saving lives. But they can be rendered useless by not using the correct components including intumescent strip. Gaps around the four sides of a fire door leaf are essential, it is the only way the door can open and close. But these gaps create a point of weakness, where fire can take hold and destroy the door, and toxic and smoke can pass through. RESSA intumescent strip works by sealing around the edges and gaps of a fire door and door frames in the event of a fire.

In essence, all intumescent do the same job, but not necessarily in the same way. You’ll need to know which specifications you require; consult our technical team to discuss this area in depth at [email protected].
