PU foam Aluminium Foil Duct Board

PU foam Aluminium Foil Duct Board also referred to as PU aluminum foil duct board or PU sandwich air duct panel, is a high-performance composite material specially engineered for HVAC heating, ventilation and air conditioning ductwork systems.

The panel features a three-layer bonded composite structure:

Two outer faces: Heavy-duty aluminum foil, available in smooth or embossed finishes

Central core: Rigid polyurethane (PU) foam, serving simultaneously as structural reinforcement and thermal insulation

Core Material: Rigid polyurethane (PUR) foam, known for its high closed-cell content (typically above 90%).

Facings: Both sides are laminated with reinforced aluminum foil, fiberglass scrim, or other vapor-retarder layers to provide durability, reflectivity, and a smooth air surface.

AvailableThickness: 20mm, 25mm, 30mm, 42mm
