Energy savings everyone can afford.
Monokote® Z-3306 Thermal Barrier is a cementitious fire protective coating specifically formulated for application over rigid, urethane and polystyrene foam plastics. Spray applied to interior foam surfaces on walls and ceilings, Z-3306 forms a hard, durable, monolithic thermal barrier against heat and fire. Z-3306 is a mill-mixed product requiring only the addition of water.
It can be easily applied to required thickness in a single pass resulting in an efficient, low cost method of meeting building code and insurance requirements.
In developing Z-3306, Grace Construction Products has utilised its experience and technology as the producer of Monokote spray applied fireproofing products — the most widely used structural steel fireproofing brand in North America. Sales and technical personnel located throughout the United States and Canada provide close technical support to contractors, owners and specifiers.
