Elastomeric Roofing - FireShield SB

TOPCOAT® FireShield® SB



Description

TOPCOAT® FireShield® SB is a solvent-based, liquid thermoplastic rubber sealant that cures to form a seamless rubber membrane. TOPCOAT® FireShield® SB Membrane will maintain, or may improve UL rating on select roofing or assemblies.** TOPCOAT® FireShield® SB Membrane is designed to enhance your roof system’s protective performance by providing unique fire extinguishing properties. Special fire resistant ingredients in the product react with heat and fire causing a chemical reaction to occur. A non-combustible carbon char layer is formed that retards flame propagation by reducing available oxygen. TOPCOAT® FireShield® SB Membrane is listed by the Cool Roof Rating CouncilSM for solar reflectance and thermal emittance. Its high reflectivity and thermal emittance will help to reduce heat gain to preserve the roof substrate, lower interior temperatures and reduce cooling costs. Sprayable, seamless TOPCOAT® FireShield® systems install fast, without the tear-off, staging, and disposal associated with traditional systems. Comprehensive warranties are available.


Uses

TOPCOAT® FireShield® SB is designed to restore BUR, modified bitumen, Hypalon®, TPO, EPDM, metal, wood, and concrete. TOPCOAT® FireShield® SB is formulated to provide maximum fire protection, increase a roof’s reflectivity and to protect the roof substrate from harmful ultraviolet rays. It is highly flexible to accommodate temperature related expansion and contraction of the roof system, a leading cause of roof system failure. Substrate shall not pond water for a period longer than 48 hours. Surface must be free of ponding water, ice, snow and debris prior to application. Do not apply at temperatures below 32°F. Substrate temperatures must be below 120°F when applying product.


Advantages
  • Highly reflective and listed by the Cool Roof Rating CouncilSM for solar reflectance and thermal emittance

  • Ideal for modified bitumen, Hypalon®, BUR, metal, TPO, wood, concrete, and EPDM

  • Designed to be applied at temperatures as low as 32°F

  • Strong; forms a flexible seal that will not become brittle

  • Flexible; will expand and contract with roof

  • Limited material warranty available for up to 10 years*

  • Guarantees available for up to 10 years*

  • Available in 5-gallon pails, 55-gallon containers, and bulk totes
