Polyisocyanuratplatten-Dämmung: Leistungsstarke Wärmelösung für modernes Bauen

Polyisocyanurate (PIR) board insulation has emerged as a top-tier solution for energy-efficient building envelopes, offering exceptional thermal performance and durability. As a closed-cell rigid foam insulation material, it’s widely specified in commercial roofing systems, wall assemblies, and industrial applications where superior R-value retention matters.

Why Choose Polyisocyanurate Insulation Boards?

1. Industry-Leading Thermal Efficiency
   With an R-value of 6.0-6.5 per inch (ASTM C518), PIR boards deliver 15-20% better thermal resistance than comparable polyurethane or XPS foam insulation. Their unique thermoset polymer structure minimizes heat transfer in both extreme cold and hot climates.
2. Enhanced Fire Safety
   Featuring a Class A fire rating (ASTM E84), these insulation boards incorporate flame-retardant additives that resist ignition and limit smoke development – a critical advantage over traditional EPS insulation.
3. Moisture & Vapor Resistance
   The closed-cell composition provides <0.5% water absorption (ASTM C272), making it ideal for roofing insulation and below-grade applications where condensation resistance is paramount.
4. Eco-Friendly Performance
   Containing 25-30% recycled content and zero ozone-depleting agents, PIR complies with LEED v4.1 standards for sustainable building materials.

Key Applications of PIR Rigid Foam Boards

• Flat Roof Systems: 40% lighter than perlite-based roofs with seamless thermal bridging prevention
• Exterior Insulation Finish Systems (EIFS): Achieve Passive House certification with continuous insulation
• Refrigerated Warehouses: Maintain consistent temperatures with λ-value of 0.023 W/mK
• Metal Building Insulation: Pre-fabricated laminated boards with reinforced foil facers

Technical Specifications

Competitive Advantages Over Alternative Insulation

• 28% Higher R-Value than extruded polystyrene (XPS) of same thickness
• 50% Lighter Weight versus phenolic foam boards
• 3x Faster Installation compared to fiberglass batt insulation
• Zero VOC Emissions unlike some spray polyurethane foams

Installation Best Practices

1. Use ISO 9001-certified polyurethane adhesives for board-to-substrate bonding
2. Stagger joints in multiple layers to eliminate air gaps
3. Apply protective facers (foil/glass fiber) in high-moisture environments
4. Maintain 6mm expansion gaps in temperatures below 5°C
