Fire Rated Foam?

Fire Rated foam, can there be an expanding foam that is fire rated?

Well to start products are not fire rated, products assembled properly according to a tested UL system are.  All of the components add up if done correctly to a rated assembly.  If you are looking for a Fire Rated product then you should be talking about a Firestop with tested UL systems.  See UL.com for details.

Our Abesco FP200 FR Expanding Foam is considered a Firestop not a Fireblock?  What is the difference?  Does FP200 have UL rated systems?

A Firestop is a fire protection system made of various components used to seal openings and joints in fire-resistance rated wall and/or floor assemblies.

Firestops are designed to restore the fire-resistance ratings of wall and/or floor assemblies by impeding the spread of fire by filling the openings with fire-resistant materials. Unprotected openings in fire separations cancel out the fire-resistance ratings of the fire separations, allowing the spread of fire, usually past the limits of the fire safety plan of a building. Firestops should be maintained in accordance with the listing, approval use, and compliance.

Fire Blocks are  ready-to-use products designed to help prevent the spread of flames and smoke in residential Type V and commercial non-rated construction. Fire blocking is a term also used to describe the material used at the mid span of a wood framed area to inhibit the advance of fire within a concealed space, thereby maintaining the structural integrity of the building during a fire.

Fire Blocks are designed to control smoke and draft in mostly residential applications and in concealed spaces for both residential and commercial buildings.  This term normally applies to wood or steel-framed single family residential homes or non-rated structures.  Fireblocks should be maintained and kept in place by the homeowner or building manager.

• ASTM E-162
• BS 476- 20 (up to 4 Hr)
• EN 1366-3 (up to 4 Hr)

Here are some important things to remember when talking about Fire Rated or Firstop products.

Important determining factors for proper firestop application are as follows:
1. What does the fire-rated system consist of?
– Wood, Gypsum, Concrete?
– Floor or Wall?
2. What is the hourly rating?
– 1, 2, 3, +… hours?
3. What are the penetrating items?
– Conduit & EMT, Steel Pipe, PVC, Joints, etc.

Abesco FP200 FR Expanding Foam is a single pack Fire Rated polyurethane expanding foam, and is specifically designed to prevent the spread of fire and smoke from one compartment to another through gaps and voids through fire rated walls or floors. This extremely versatile foam mixture is easy to use – just insert and fill – and has excellent
fill capabilities along with excellent adhesion to most building substrates to foam a semi-rigid seal.

The design also provides a level of sound dampening for use in acoustic applications (STC 38), and when combined with sound rated wall assemblies, can replicate the rated sound attenuation. Because of its closed cell composition, it also provides excellent thermal properties (R 7/inch [2.54 cm]) when used as an insulator. Excellent smoke and flame ratings are also achieved by full range testing to ASTM E-84 (flame 10, smoke 35) and can be used for Green and LEED type applications.
The FP 200 FR Expanding Foam has been tested around the full scale ASTM E-814 including a full hose stream impact for 1 & 2 hour F ratings. Most competitive products only test to a modified ASTM E-814 with no hose stream exposure. In addition, the product meets all the requirements for Type V residential ratings.

The product is designed to replace messy caulks and non-rated or modified foam products as a fire stopping medium.

Our FP200 can even be used as a backer material when using other fire rated caulks. It also surpasses other fire block materials based on the full range of complete ASTM E-814 testing. The product may also be trimmed after curing and either painted or stained to a desired color.
