Firestop and Fireblock

Firestop and Fireblock Benefits

Firestop and fireblock products are designed to fill gaps and cavities in order to make structures more resistant to the spread of fire and smoke.

Save Lives

If a building catches fire, oxygen fuels the flames. Filling gaps and cracks in structures with firestop or fireblock helps prevent the spread of fire in walls and floors. With a slower spreading fire and less smoke throughout a structure, occupants have more time to get out safely.

Use Throughout A Structure

Firestop can be applied anywhere in a structure, including walls and floors. Some common applications for firestop foam include around electrical, mechanical and structural penetrations, head-of-wall joints, and control or sway joints. Even small spaces need to be filled. It can be used in residential and commercial applications.

Meet Fire Code

Many construction projects have to meet certain codes, including fire safety. Be sure to check code requirements in your area before choosing a firestop product. You can always check with a local inspector before beginning a project. Some applications require vertical fireblock but not horizontal fireblock.

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.

Putty

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.

Sprays (Coatings)

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

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.
