Myreal Insulation's Pur/pir
MYREAL Energy Saving (Shanghai) Co., Ltd. has a series of deliberate production plans for pur/pir. From raw material and spare parts to assembling and packaging, we strictly enforce the production schedule and technological process so as to ensure reasonable resource allocation and optimized production process.
pur/pir is vital for MYREAL Energy Saving (Shanghai) Co., Ltd. to achieve business success. Cast by raw materials which meet the quality standards, it is featured by a high degree of stability and long-term durability. In order to meet international standards for quality, preliminary tests are repeatedly implemented. The product gains more recognition from the customers by its stable performance.
These panels utilize advanced polymer technology to provide reliable climate control and reduced energy consumption. Engineered for modern construction, they integrate easily into diverse building systems with high-performance insulation. The material ensures exceptional thermal efficiency and durability for optimal indoor environments.
PUR/PIR insulation materials offer superior thermal efficiency and durability, reducing long-term energy costs while maintaining structural integrity in diverse environments. Their closed-cell structure minimizes heat transfer, making them ideal for energy-conscious construction projects.
Commonly used in residential and commercial buildings for insulating walls, roofs, and floors, PUR/PIR also suits industrial applications like refrigeration systems, pipelines, and cold storage facilities where consistent temperature control is critical.
Select PUR/PIR panels or foam based on required R-value (thermal resistance), thickness, and fire safety ratings. For spray applications, prioritize professional installation to ensure even coverage and compliance with local building codes.
PUR & PIR Sandwich Panels for Cold Storage and Clean Rooms
When it comes to building efficient cold storage facilities or sterile clean rooms, the choice of insulation material and panel configuration is critical. PUR (Polyurethane) and PIR (Polyisocyanurate) sandwich panels have become the preferred solution due to their excellent thermal insulation, structural strength, and ease of installation.
1. Panel Composition
Surface Materials (Facing):
Galvanized Steel / Aluminum / Stainless Steel
Thickness: 0.4–1.0 mm (~0.016–0.04 inch)
Coating: Polyester, PVDF, or food-grade coatings for hygienic surfaces
Advantages: Corrosion-resistant, easy to clean, durable
Core Materials:
PUR (Polyurethane Foam):
Density: 40–45 kg/m³ (~2.5–2.8 lb/ft³)
Thermal Conductivity (k-value): 0.022–0.024 W/(m·K) (~0.15–0.16 BTU·in/hr·ft²·°F)
PIR (Polyisocyanurate Foam):
Density: 45–50 kg/m³ (~2.8–3.1 lb/ft³)
Thermal Conductivity (k-value): 0.021–0.023 W/(m·K) (~0.14–0.15 BTU·in/hr·ft²·°F)
Advantages: Better fire resistance than standard PUR
Note on R-values:
R-value = Thickness / k-value
For example, a 100 mm (~4 inch) PIR panel with k = 0.022 W/(m·K) gives R ≈ 4.55 m²·K/W (~25.5 ft²·°F·hr/BTU).
2. Panel Dimensions
Standard Thickness: 50–200 mm (~2–8 inch)
Width: 1.0–1.2 m (~39–47 inch)
Length: Up to 12 m (~39.4 ft), customizable
Tip: For cold storage, thicker panels (6–8 inch) are recommended for low-temperature storage below -20°C (-4°F).
