FSP Firestop Putty
Brand: NelsonNelson Firestop Putty (FSP) is a completely premixed and ready-to-use firestop product that can be hand pressed into place forming an immediate fire seal.
When exposed to fire the putty material forms a hard char that creates a formidable barrier to smoke and flame.
FSP is a blend of organic and inorganic materials that is hand moldable. FSP is reusable when adding or changing penetrating items since the material remains pliable and does not set up.
Features- Easily installed, highly pliable and reusable.
- Requires no special skills or tools for installation.
- It inhibits the passage of smoke, and flame, through penetrations and joints. It is ideal for cable penetrations, where cable additions are common.
- To ensure adequate adhesion, all surfaces should be clean and free of dust, grease, oil, loose materials, rust or other substances.
- Apply the required depth of FSP over various backing materials. Ensure that it makes complete contact with the inside surface of the opening, as well as the surface of each penetrating item.
- Actual installation should be in accordance with the appropriate Nelson™ application system drawing.
- Up to 3 hour rating.
- Smoke and gas tight; weather resistant.
- Acoustically tested; reduces noise transmission.
