- Product Highlights
- INSS2460 is designed to seal the gaps around penetrations through fire-rated floors, walls or other assemblies as well as for sealing gaps around window and door frames in critically fire-rated structures.
- INSS2460+ is a sprayable silicone-based firestop sealant that offers excellent flexibility, is waterproof and tested for up to a 3-hour joint system by UL2079 and ULC-S115.
- Both products adhere to most construction materials including concrete, stone, plaster, metals, glass and plastics.
- They are installation-friendly, are asbestos and halogen-free and ideal for interior and exterior use or where contact with moisture is a concern.
- Once fully cured, this offer excellent weathering characteristics including UV resistance, cold temperature flexibility, dry heat aging and resistance to chalking.

- This product is not intended for use in fire-rated construction.
- Installation Guide
- Before applying, clean the surface of the opening and any penetrating items to allow for proper adhesion.
- Use mineral spirits or similar products to clean surfaces (Do not use alcohol).
- Ensure that the surface of the substrates is dry and frost-free.
- Install the correct depth and compression of backing material, if required, as detailed within the applicable Listed system.
- INSS2460 can be installed with a caulking gun, putty knife, or trowel. INSS2460+ can be applied by an airless sprayer.
- Install the applicable depth of INSS2460/INSS2460+ into the opening flush with the surface of the substrate, or as detailed within the Listed system to meet the required assembly rating.
- Tool the sealant surface smooth using a putty knife dipped in water making complete contact with substrates to ensure an air and smoke tight seal.
- Using mineral spirits, clean all tools and flush spray equipment immediately after use.
