Polyurethane Spray
Foam Insulation
Polyurethane Spray – Foam Insulation was developed specially for spraying roofs.
The system is used mainly for:
The seamless sealing and insulation of roofs residential and industrial building.
Roof renovation i.e for the formation on industrial building roofs.
The use of spray-applied polyurethane foam is highly effective way of achieving effective thermal insulation coupled with sealing substrate. The versatile method is applicable to residential, commercial, warehouses and industrial buildings-inside and out and is suitable for both new and remedial work. A coating must be applied to ensure reliable, long-tem effectiveness and protection from UV.

Why Choose A Spray Foam Roof
- > The roof are is highly INSULATED
- > ECONOMY – rapidly pays for itself in energy savings
- > No more gaps and LEAKS
- > Noise is reduced or ELIMINATED
- > Rust is eliminated
- > Last indefinitely when properly protected
- > Withstands ponding water
- > Seamless no week points for water enter
- > Strongly adheres to surface
- > Speed of application less time to apply than conventional less efficent system
- > Ultra Violet (UV) stable (coasting required)
- > Flexible moves with structure in normal expansion and contraction condiotion
