Double-Sided Aluminum Foil PIR Fire-Resistant Insulation Profiled Duct Board

Polyurethane (PU) Foam Pre-Insulated Air Ducts are used for air distribution in central air conditioning systems. The ducts are made from PU Foam Sandwich Panels, which consist of rigid polyurethane insulation foam sandwiched between two layers of 80-micron aluminum foil for low vapor permeability and protection.

Polyurethane (PU) Foam Pre-insulated Air Duct is used for air distribution in central air conditioning. The air ducts are made of  PU Foam Sanwich Panels, the panels composite rigid polyurethane insulation foam faced on both sides with a protective low vapour permeability 80 micro aluminium foil.  

PU composite duct boards（panels） are made of polyurethane foam material and color steel composite, not only have the thermal insulation characteristics of polyurethane foam boards, but also have the weather resistance and corrosion resistance of color steel plates.

PU composite duct Panel（board）, crafted from polyurethane foam and covered with color steel, which has dual advantage.They inherit the superior thermal insulation properties of polyurethane foam while also boasting the weather resistance and corrosion resistance typically associated with color steel plates.

PU composite duct Panel（board） is a type of panel made from multiple layers of materials bonded together, featuring fire resistance, sound insulation, and thermal insulation properties. It is typically composed of materials such as aluminum alloy sheets, glass fiber cloth, and polyurethane foam layers.

Phenolic foam is a new type of fire-retardant, fire-proof and low-smoke insulation material, which is made of phenolic resin with fire retardant, smoke suppression agent, foaming agent, curing agent, and other additives added.

Phenolic foam is a new type of fire-retardant, a closed-cell rigid foamed plastic.It has been mostly characterized with fire-retardant, low-smoke and high temperature deformation resistant features. 

Phenolic foam has overcome the shortcomings of flammability, smokiness and thermal deformation for the original foamed plastic insulation material, but it has maintained the advantages of light weight, convenience for construction, etc for the original foamed plastic insulation material.
