Why Fire rated sealant?
Fire rated sealant and Sprays is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestop sealant is designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.
Fire caulk is used in:
- Electrical, mechanical, and structural penetrations
- Unpenetrated openings (such as openings for future use)
- Re-entries of existing fire stop
- Control or sway joints in fire-resistance-rated wall or floor assemblies
- Junctions between fire-resistance-rated wall or floor assemblies
- Head-of-wall joints, where non-load-bearing wall assemblies meet floor assemblie
What is fire stopping?
Fire stopping is best defined as the sealing of any openings to prevent fire (including smoke and heat) from passing through multiple building compartments. The spread of a fire is contained by creating fire resisting compartments, which subdivide the building (vertically or horizontally). Buildings must ensure that any openings and gaps are fire stopped to restrict both lateral and vertical fire spread. Fire rated sealant Delhi
The Wiki firestop definition is:
A firestop is a fire protection system made of various components used to seal openings and joints in fire-resistance rated wall or floor assemblies. For penetrating cables, these can also be called as Multi Cable Transits (MCTs). Firestops are designed to restore the continuous fire-resistance of wall or floor assemblies, impeding the spread of fire by filling the openings in them with fire-resistant materials.’
Fire sealants and gap fillers expand when heated at high temperatures, to prevent the spread of fire and smoke. There are different kinds of sealants for different substrates and applications.
What does FR B1 certified mean?
The abbreviation FR or RF stands for fire retardant or fire resistance of the material. This is important for materials like banners, that are often used in places with many visitors such as trade fairs, exhibitions and festivals. From a safety point of view, it is important that a banner does not immediately catch fire if a fire should occur. The European Community has created this certificate/label to be able to easily compare materials with regards to their flammability.
In Figure 1 and Table 1 we give an overview of all possible labels regarding the degree of flammability. It shows that materials with classification B1 are flame resistant and are therefore well suited for use at trade shows and expos.

| Classification | Flammability |
|---|---|
| A | Not flammable |
| B1 | Hardly flammable |
| B2 | Very difficult |
| C | Difficult |
| D | Average |
| E | Easily flammable |
| F | Not determined |
