Rigid Foam Insulation Core PUR Board 50 mm High Density Closed Cell Panel

A rigid foam insulation core decides how a sandwich panel behaves after twenty years on a roof. This 50 mm PUR board is foamed to a core density of fifty kilograms per cubic metre, which keeps the cell walls stiff under handling, screw fixing and lamination heat. The rigid foam insulation core does not sag or creep, so the panel keeps the thickness it was designed with.

The foam is closed cell, with water absorption below five percent by volume and a declared conductivity of 0.023 W/(m.K). That combination is why a rigid foam insulation core is chosen for cold service and humid plant rooms, where open cell foam would slowly fill with moisture and lose its thermal value. Boards are trimmed square and calibrated so laminators can bond facings without voids.

For buyers comparing factories, the practical test of a rigid foam insulation core is batch repeatability. We check core density, compressive strength and oxygen index on every lot, and a rigid foam insulation core board ships with its own test record so the panel line in Europe receives the same foam as the approved sample.

Key Advantages

• Core density 50 kg/m3 keeps the board stiff under lamination pressure
• Closed cell foam with water absorption below five percent
• Conductivity of 0.023 W/(m.K) verified lot by lot
• Compressive and tensile strength both above 200 kPa
• Rigid foam insulation core resists creep under permanent roof loads
• Square trimmed edges keep bond lines free from voids
