FireShield® SB
Description
FireShield® SB Elastomeric Roofing Membrane is a solvent-based, liquid
thermoplastic rubber sealant that cures to form a seamless rubber membrane. FireShield®
SB with it's patent-pending technology will maintain, or may improve UL rating on
select roofing or assemblies.** FireShield® SB 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. FireShield®
SB 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 FireShield® systems install
fast, without the tear-off, staging, and disposal associated with traditional systems.
Comprehensive warranties are available.
Uses
FireShield® SB Elastomeric Roofing Membrane is designed to restore
BUR, modified bitumen, Hypalon®, TPO, EPDM, metal, wood, and concrete.
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
