Insulated PUF (Polyurethane Foam) wall panels are commonly used for their thermal insulation properties in various construction applications. Key specifications include panel thickness, density, sheet thickness, U-value, and fire resistance. Thickness typically ranges from 30mm to 150mm, with densities around 40 kg/m³. Sheet thicknesses are often 0.30mm or 0.50mm, and U-values vary based on thickness, with lower values indicating better insulation.
