Firestop and Fireblock Accessory Types
Firestop and fireblock products come in several different forms. If you are unsure of which firestop sealant to use, ask your local Service Partners professional.
One Part Sealants (Caulk)
These products include water-based intumescent sealants that are the flagship product for most firestop manufacturers. They can be used for both combustible and non-combustible applications. Additionally, there are silicone non-intumescent sealants that are best suited for applications where penetrations may move or vibrate, in wash down areas, or where W ratings are required.
Firestop putty is primary used on small cable penetrations (typically HTO). Putty is non-hardening and can be worked by hand. Many times the seal can be re-entered making these spaces easy to access in the future. It is also good for use around metal pipes and electrical boxes.
Cementitious Mortars and Grouts
Firestop mortars and grouts are cost-conscious firestop solutions for large openings in concrete walls and floors. These products are mixed with water and then are applied into concrete walls and floors. Cementitious mortars and grouts cure quickly and allow for future penetrants.
Firestop sprays are coatings that adhere to various construction substrates and are spray-applied. Firestop sprays can be applied using spray equipment or with a brush. Firestop sprays are commonly used for construction joints and perimeter fire barrier applications.
Intumescent wraps are available in a variety of sizes and types for use on combustible penetrations. Using intumescent wraps can minimize waste and speed up firestop installation. These wraps are commonly used on plastic piping up to 12 inches in diameter.
Pillows, Bags or Blocks
Pillows are intumescent products that are soft and cushion-like. They are designed to be compressed and stuffed into openings around penetrants. Poly Bags are intumescent products that protect core materials and allow for easy insertion and removal. Poly Bags burg away quickly and cleanly during a fire.
