# Heavy Duty Insulation

This is a multi-layer seamless polyurethane spray foam system featuring an outer prefabricated barrier of stainless steel mesh-reinforced polyurea, specifically ToughCoat®. The final step involves injecting PU foam between the sprayed layers and the ToughCoat®, ensuring 100% bonding, tension, and a flawless surface.

**Features:**

- Enhances the prefabricated surface for a smoother finish free of pinholes.
- Elevates the fire retardant properties of the system.
- Incorporates a reinforcement system to prevent cracks and delamination.
- Bolsters the mechanical properties of the reinforced surface.
