- Fire Performance: Complies with ASTM E84, Class 1 / Class 0 ratings available.
- Key Features: Excellent resistance to water vapor diffusion (µ > 7,000), low smoke emission, and superior flexibility for easy installation on pipes and ducts.
2. Polyisocyanurate (PIR) Rigid Board Insulation
A top choice for wall, roof, and continuous insulation in commercial buildings due to its high R-value per unit thickness.
- Primary Material: Polyisocyanurate foam with reinforced facers (foil, glass, composite).
- Temperature Range: -180°C to 140°C (-290°F to 285°F).
- Thermal Conductivity (k-value): 0.022 - 0.026 W/(m·K) at 24°C.
- Fire Performance: Typically achieves Class A/Class 1 ratings; core is inherently fire-retardant.
- Key Features: High compressive strength (100+ kPa), dimensional stability, and long-term thermal resistance (LTTR) values.
3. Mineral Wool Insulation (Stone Wool & Glass Wool)
Provides outstanding fire resistance and acoustic control, used in fire-stopping, industrial equipment, and high-temperature piping.
- Primary Material: Basalt rock or recycled glass spun into fibrous mats or boards.
- Temperature Range: Up to 750°C (1380°F) for certain stone wool products.
- Thermal Conductivity (k-value): 0.033 - 0.044 W/(m·K) at 24°C.
- Fire Performance: Non-combustible (ASTM E136, Euroclass A1).
- Key Features: Excellent sound absorption (NRC up to 1.0), water-repellent (hydrophobic), and vapor permeable.

Insulation Products FAQ: Answers from Kaxite Sealing Experts
Q: What is the most important factor when comparing different insulation products?
A: While R-value (thermal resistance) is crucial, it should not be the sole factor. Consider the application's full context: operating temperature range, exposure to moisture, fire safety requirements, acoustic needs, and mechanical durability. For instance, a high R-value material that absorbs water will quickly lose its effectiveness. Kaxite Sealing products are designed with a holistic performance profile.
Q: How does insulation thickness relate to R-value and performance?
A: R-value is proportional to thickness for a given material. Doubling the thickness typically doubles the R-value, significantly improving thermal performance. However, other factors like thermal bridging (where heat bypasses the insulation through structural elements) become more critical in highly insulated assemblies. Kaxite Sealing provides solutions like continuous insulation boards to mitigate thermal bridging.
Q: Can Kaxite Sealing insulation products be used in both hot and cold applications?
A: Our portfolio covers extreme ranges. Flexible Elastomeric Foam is optimized for sub-ambient to moderate temperature applications. For high-temperature processes (e.g., industrial piping, exhaust systems), our Mineral Wool products are the recommended choice due to their non-combustible nature and stability at high temperatures. Always check the specific product's stated temperature limits.
Q: What fire safety certifications should I look for in insulation?
A: Key standards include ASTM E84 (Surface Burning Characteristics) in North America, which assigns Flame Spread and Smoke Developed indices—Class 1 (or A) is best. In Europe, look for Euroclass ratings (A1 being non-combustible). Kaxite Sealing rigorously tests its products, and certifications are available on our technical datasheets to ensure compliance with local building codes.
Q: How does insulation contribute to acoustic comfort?
A: Insulation absorbs sound waves, reducing noise transmission through walls, floors, and ceilings. Materials with a fibrous or open structure, like Kaxite Mineral Wool or Glass Wool, are particularly effective as they trap sound energy. We specify Noise Reduction Coefficient (NRC) and Sound Transmission Class (STC) ratings to help you select the right product for acoustic control.
Q: Are Kaxite Sealing products environmentally friendly?
A: Sustainability is integral to our manufacturing. Many products, like our Glass Wool, contain high levels of recycled content. PIR foam uses blowing agents with low Global Warming Potential (GWP). Most importantly, the energy savings enabled by proper insulation over a building's lifecycle far outweigh the embodied energy of the product, contributing significantly to reduced carbon emissions.
Q: How do I ensure proper installation to achieve the stated performance?
A: Performance depends on correct installation. Ensure joints are tightly butted and sealed with appropriate tape or adhesive. For pipe insulation, use the correct wall thickness for the pipe size and ambient conditions. Avoid compressing batts in wall cavities, as this reduces their R-value. Kaxite Sealing provides comprehensive installation guides and technical support for all our systems.
Specifying for Success: Beyond Basic Parameters
True specification mastery involves understanding secondary but vital characteristics. When evaluating Kaxite Sealing insulation products, also consider:
- Compressive Strength: Critical for insulation under floors, roofs, or mechanical loads. Our PIR boards offer high strength-to-weight ratios.
- Long-Term Thermal Resistance (LTTR): Some foams experience thermal drift. Kaxite PIR products are tested for LTTR, guaranteeing a stable, aged R-value.
- Chemical and UV Resistance: For exposed or industrial environments. Our FEF and certain faced boards offer excellent resistance to oils, chemicals, and sunlight degradation.
- Hygienic Properties: In food, pharmaceutical, or healthcare settings, insulation must resist mold and microbial growth. Kaxite products are available with anti-microbial treatments.
Selecting the optimal insulation is a technical process that balances multiple performance vectors. With Kaxite Sealing, you partner with a provider whose depth of knowledge is matched only by the quality and precision of our product range.
