PU Foam Insulation — High-Performance Thermal Solution for Agriculture & Industry
Polyurethane (PU) foam insulation for agricultural warehouses, industrial facilities and cold storage — superior thermal resistance, moisture protection and air sealing that keeps indoor conditions optimal while cutting energy costs.
Why it matters
Poorly insulated agricultural and industrial buildings waste energy, suffer condensation and mould, and offer little protection against pests and air leakage. Polyurethane (PU) foam tackles all of these in a single, seamless application — its superior thermal resistance, moisture protection and air-sealing capabilities keep indoor conditions optimal while significantly reducing energy costs.
What is PU foam insulation?
Polyurethane (PU) foam is a rigid, closed-cell insulation material created by mixing polyol and isocyanate, which react to expand and form a dense, durable foam. Once applied, the foam adheres tightly to surfaces, creating a seamless thermal barrier that outperforms traditional insulation types in both performance and longevity.
Key features & benefits
High insulating value
R-values of R-6 to R-7 per inch — ideal for temperature-sensitive environments including grain storage, livestock housing and industrial cold rooms.
Moisture & vapour resistance
The closed-cell structure resists water absorption, preventing mould, mildew and condensation and protecting goods from humidity-related damage.
Air & pest sealing
Creates an airtight seal that blocks dust, insects, rodents and outdoor pollutants — crucial for maintaining hygiene in food-grade and seed-storage environments.
Durability & fire protection
Fire-retardant additives are available (intumescent coatings or drywall barriers) to meet building codes, and the foam delivers long-term performance without sagging or settling over time.
Energy efficiency
Reduces HVAC load by maintaining stable internal temperatures, cutting energy consumption by up to 50% — a major benefit for climate-controlled storage and industrial processes.
Installation & versatility
Available as spray or pre-formed panels: spray suits irregular surfaces and metal buildings, while panels are ideal for new builds.
Eco-friendly & cost-effective
Reduces energy waste and carbon footprint, while a long service life minimises replacement costs and can contribute to LEED certification.
