Types of Fire Sealants
There are several types of fire sealants available, each with unique properties that make them suitable for different applications. Here are a few examples:
- Intumescent sealants: These sealants expand when exposed to heat, forming a foam-like barrier that can block or limit the spread of fire and smoke. Intumescent sealants such as our SabreSeal FRA are commonly used in joints and gaps around the electrical conduit, plumbing, and other penetrations through fire-rated walls and floors.
- Acrylic sealants: Acrylic sealants are also water-based and can be used in a wide range of applications. They have good durability, UV resistance can be paintable but may not withstand high temperatures as well as some other types of sealants.
- Silicone sealants: Silicone sealants are known for their excellent heat resistance and durability. They are often used in exterior applications, such as sealing around windows and door frames.
- MS Polymer Sealants: MS polymer sealants such as our Hybriflex FR are commonly used in exterior applications, such as sealing expansion joints in concrete precast panels or facades.
- Firestop Mortar: A firestop mortar is a passive fire protection system typically used in applications such as opening in walls, floors and ceilings, around penetrations such as pipe, conduit, cable trays, etc. They dry and harden to create a barrier that prevents the spread of fire and smoke.
Sabre, as a premier provider, offers a complete spectrum of fire sealants in New Zealand, ensuring comprehensive solutions for sealing gaps and openings in buildings to prevent the spread of fire across various applications.
Fire Sealants: Field of Applications
Fire sealants are used in a variety of commercial and residential building applications to help prevent the spread of fire and smoke. Among the most common applications are:
- Sealing gaps and openings around electrical conduits, plumbing, and other penetrations in fire-rated walls and floors.
- Sealing gaps around windows, door frames, and other exterior joints.
- Sealing gaps around baseboards, trim, and other interior finishes.
- Firestopping of openings in walls, floors and ceilings.
- Sealing gaps around fireproofing materials, such as sprayed insulation.
- In addition to this traditional application, these sealants can also be used to seal gaps and cracks around air ducts, electrical panels, and other building components to prevent the spread of fire and smoke.
When selecting a fire sealant, it is important to consider the specific requirements of your application, including the type of construction, the size of the gaps or openings to be sealed, and the fire rating required. It is also important to use a sealant that is tested and certified by an independent testing agency to ensure it meets the appropriate fire safety standards. Also, it is important that the used fire sealants are compliant with the local building code and have the appropriate fire rating for the specific application.
