MONOKOTE Z3306

  • Gypsum based
  • Formulated as fire protective for polyurethane plastics (SPF)
  • Seamless barrier
  • Can ULC S124m compliant

It can be applied to whatever thickness is required to meet building code and insurance requirements.

Monokote dries to a hard, durable surface which resists damage. It is naturally grey in colour but can be painted with latex paint to desired colour.

FAQ

Q: What is a thermal barrier?

A: A thermal barrier is a material, applied between spray polyurethane foam (SPF) and interior spaces designed to slow the temperature rise of the SPF during a fire situation, and to delay the SPF’s involvement in a fire. A building code definition of an approved thermal barrier is one which is equal in fire resistance to 12.7 mm (1/2 inch) gypsum board. Thermal barriers meeting this criterion are termed a “15-minute thermal barrier” or classified as having an “index of 15.”

Q: Is a thermal barrier required on insulation on the exterior of a structure, such as a roof?

A: A thermal barrier is not normally required for SPF applied on the exterior of the structure (i.e., roof insulation).

Q: Is a thermal barrier required on sprayed polyurethane foam insulation?

SPF, like most other organic materials, is combustible. SPFs are formulated with flame retardants to decrease the flame spread. When exposed to fire sources, such as trash fires, welding arcs, cutting torches, or red-hot metal, unprotected SPF in interior situations may ignite resulting in a flash fire.
Codes require thermal barriers for interiors to reduce the risk of a flash fire and to extend the time at which the foam would reach its auto ignition temperature should a fire originate from other sources.
