Density
The density of polyurethane foam plays a crucial role in determining its insulating properties. A higher density foam generally offers better compressive strength and durability, while a lower density foam is lighter and easier to install. The optimal density for roofing insulation depends on the specific application and the desired level of performance.
Thermal Conductivity
Thermal conductivity is a key factor in determining the effectiveness of a roofing insulation material. The lower the thermal conductivity, the better the material is at preventing heat transfer. PURFHS helps reduce the thermal conductivity of polyurethane foam, making it an excellent choice for energy-efficient roofing systems.
Compressive Strength
The compressive strength of polyurethane foam is important for ensuring that it can withstand the weight of snow, ice, and other loads without deforming. PURFHS enhances the compressive strength of the foam, making it suitable for use in areas with heavy snowfall or high wind loads.
Water Absorption
Water absorption is a critical parameter for roofing insulation materials, as excessive moisture can lead to mold growth, structural damage, and reduced thermal performance. PURFHS helps minimize water absorption by forming a protective barrier around the foam, ensuring that it remains dry and effective over time.
Flame Spread and Smoke Developed Indices
Fire safety is a top priority in any building project, and PURFHS plays a vital role in improving the fire resistance of polyurethane foam.
