PU Foam
Insulation
Closed-cell spray polyurethane foam — the highest-performance thermal insulation for UAE’s extreme heat. Applied to roofs, tanks, pipes, and structures.
INTRODUCTION
Polyurethane (PU) foam insulation is one of the most effective and versatile insulation technologies available. With an exceptionally low thermal conductivity, PU foam provides superior insulating performance at minimum thickness — ideal for the UAE’s space-constrained industrial and commercial environments.
PU Foam Application Methods
| Type | Characteristics & Applications |
|---|---|
| Spray Applied PU Foam (SPF) | Two-component PU foam sprayed in-situ to form a continuous, seamless insulation layer. Ideal for complex surfaces, tanks, pipes, and irregular geometries. Adheres to most substrates. |
| Rigid PU Board Insulation | Factory-manufactured PU boards cut and installed with adhesive and mechanical fasteners. Used for flat roofs, walls, and ductwork insulation. |
| Pre-Insulated GRP Pipe Systems | PU foam injected between GRP pipe and outer GRP jacket — factory-manufactured for consistent insulation thickness and quality. |
Technical Properties
| Property | Value |
|---|---|
| Thermal Conductivity (λ) | 0.022 – 0.028 W/m·K (superior to most other insulation types) |
| Density | 30 – 80 kg/m³ depending on application |
| Temperature Range | -60°C to +120°C (standard grades) |
| Water Absorption | Very low — closed-cell structure resists moisture ingress |
| Fire Rating | Self-extinguishing grades available (ASTM E84, BS 476) |
BENEFITS
- Best-in-class thermal performance at minimum thickness
- Seamless application eliminates cold bridging and joint losses
- Adheres to concrete, steel, GRP, masonry, and most substrates without mechanical fixings
- Closed-cell structure provides both thermal insulation and vapour barrier in a single application
- Dramatically reduces energy consumption for cooled and heated spaces in UAE climate
