  • Pre-insulated PU Foam Duct Board

    Pre-insulated PU Foam Duct Board

    Polyurethane (PU) foam is a new kind of thermal insulating material for low temperature applications. It is mainly made from polyether or polyester plus isocyanate ester added with flame retardant, stabilizing agent and foaming agent and it changes into foaming body through chemical reaction after mixed and stirred.

    It has following features: low thermal conductivity, high strength, light weight, quakeproof, insulation, strong floatability, stable chemical properties and convenience in construction. Consequently, it is widely used in industries of petroleum, chemical engineering, ethylene, refrigerated warehouse, food storage, and architecture industry.

  • PIR insulation board

    Pre-insulated PIR Foam Duct Board

    Polyisocyanurate (PIR) foam is a kind of foaming material which can be made after the reaction of isocyanate, catalysis and polyether. It’s better than common polyurethane foam in physical properties and flame resistance.

    PIR foam air duct offers a high performance, lightweight and robust ductwork system that requires only a single fix installation process. This not only makes it a high speed operation for projects, but also provides the advantage of a considerable saving in cost and space. It can make a saving of over 20% on operating cost over a 30 year life.

  •  polyurethane foam rigid

    PIR (polyurethane ) Pipe insulation

    Polyisocyanurate (PIR) foam is a kind of foaming material which can be made after the reaction of isocyanate, catalysis and polyether. It’s better than common polyurethane foam in physical properties and flame resistance.

    CASAVERDE supplies all kinds of PIR foam insulation, we make sure that the delivery time is short, not only the quality but also the price  are both  better  than  the same industry
