Polyurethane Insulation Board

Polyurethane insulation board (PU insulation board) is a high-efficiency composite insulation material. It is composed of a rigid polyurethane foam core and surface-facing materials (common options include color steel plates, aluminum foil, galvanized steel plates, or fiberglass fabrics), integrated through continuous production processes like lamination or casting. Renowned for its exceptional thermal insulation efficiency, lightweight design, and strong structural integrity, it is widely applied in building insulation, cold chain logistics, industrial equipment, and other fields requiring energy conservation and thermal preservation.

Core Characteristics

Outstanding Thermal Insulation: With an ultra-low thermal conductivity (≤0.024 W/(m·K)), it offers better heat preservation and energy-saving effects than traditional insulation materials. It reduces heating and cooling energy consumption by 30-50% in buildings.

Lightweight & High Strength: The polyurethane foam core is lightweight (density 30-50 kg/m³), while the composite structure with surface panels provides excellent load-bearing capacity and impact resistance, avoiding deformation during transportation and installation.

Superior Waterproof Performance: The closed-cell structure of polyurethane foam (closed-cell rate ≥90%) prevents water absorption and moisture penetration. It eliminates the need for additional waterproof layers in many applications, simplifying construction.

Easy Installation & Versatility: Prefabricated with standardized sizes, the boards enable quick on-site splicing and cutting. They adapt to various structural forms, including curved surfaces and irregular shapes.

Durable & Environmentally Friendly: High-quality PU insulation boards resist aging, corrosion, and insect infestation, with a service life of 15-25 years. Modern products comply with environmental standards, containing no ozone-depleting substances.

Typical Applications

Building industry: External wall insulation, roof insulation, interior partitions, and prefabricated building envelopes.

Cold chain & refrigeration: Cold storage warehouses, refrigerated trucks, container cold rooms, and freezer equipment.

Industrial fields: Thermal insulation for pipelines, boilers, and industrial equipment; sound insulation for workshops and power stations.

Civil engineering: Thermal insulation for bridges, tunnels, and basement walls; moisture-proof layers for floors.
