PUF insulation (Polyurethane Foam) is a high-performance thermal insulation material formed by reacting isocyanates with polyols. Widely used in HVAC systems, it offers excellent thermal resistance, long-term durability, and easy installation, making it ideal for areas demanding superior temperature control, such as cold rooms, ductwork, and equipment enclosures.
PUF insulation is capable of withstanding extremely low temperatures (up to -50°C) and is often combined with outer cladding materials like aluminum, steel, or galvanized sheets for enhanced protection. Common types include Open-Cell PUF (flexible and breathable), Closed-Cell PUF (rigid and highly insulating), and Spray PUF, which is perfect for irregular surfaces and tight spaces.

Polyurethane foam insulation is a highly effective thermal insulating material known for its low density, exceptional thermal resistance, and strong mechanical properties. It comes in open-cell and closed-cell varieties— both proving valuable for building, HVAC, and industrial applications.
Closed-cell foam offers high R-values—up to R-6.7 per inch—and acts as both air and vapor barrier, minimizing heat transfer and air leakage.
Open-cell foam provides excellent sound absorption due to its porous structure, making it a strong acoustic insulator.
High R-value per inch reduces thickness needed for effective insulation.
Expands to fill cracks, eliminating drafts and preventing thermal bridging.
Minimizes condensation, protecting structure integrity and enhancing energy savings.
Effective for both thermal and acoustic control in one application.
Perfect for walls, roofs, floors, HVAC ducts, and hard-to-reach cavities.
Spray polyurethane foam (SPF) transforms building performance by creating a continuous, airtight layer. Benefits include enhanced temperature control, reduced HVAC load, and improved indoor air quality. Its ability to tightly seal surfaces and penetrate gaps ensures long-term efficiency and structural protection.
Provides effective insulation, ensuring a comfortable and consistent indoor climate year-round.
Minimizes energy use by reducing the workload on HVAC systems, lowering operational costs.
Airtight sealing helps prevent the infiltration of dust, pollen, and pollutants, promoting healthier indoor air.
Ensures durable, energy-efficient insulation for years, reducing the need for frequent repairs or replacements.
Polyurethane Foam (PUF) insulation is a high-performance thermal (and acoustic) insulation material made by reacting isocyanates with polyols. It’s used widely in HVAC systems, cold rooms, ductwork, and equipment enclosures.
It can handle very low temperatures (for example −50 °C), making it suitable for cold rooms, freezers, etc.
The closed-cell version helps to act as a vapor/air barrier, reducing moisture ingress and condensation. Proper installation is critical to avoid moisture problems.
Open-cell PU foam has good sound absorption because of its porous structure. Closed-cell is less about sound and more about thermal/moisture control.
Yes, it works well in walls, roofs, floors, ductwork, panels, and irregular/hard-to-reach spaces (with spray foam). However, needs proper protection (cladding, coatings) where exposed or subjected to mechanical damage.
