  • 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

Polyurethane Duct Panel for Indoor Air-Conditioning

  • 2017-11-16 10:05:48

The Polyurethane duct panel is a technologically advanced & energy saving vent system used for heating, room ventilation and air conditioning. Apart from being affordable it’s also very environmentally-friendly. Due to their advanced features, they are considered the best products in terms of maintaining indoor air quality and thermal comfort.

Apart from material quality other factors that make Polyurethane duct panels stand out are layout design, sizing and detailing which ensure that pressure is evenly distributed throughout the system for effective air distribution. These products typically consist of an extra insulation layer with low-vapor permeability ratio of 80 micron. This helps in protecting them from chemicals and other contaminants that may be in the environment. Unlike other vents available in the market, these ones are flexible and can be fabricated to different custom shapes and designs as per the user’s wish.

Advantages

1. They are low density and lightweight

2. Fitted with Hermetic seal which ensures that no air-leakage happens

3. Lacks CFC components and is therefore environmentally safe

4. Has lowered heat conductivity and advanced thermal efficiency

5. Waterproof and sound-insulated with closed-cell structure foam

6. No protrudent flanges around the duct connections, which saves a lot in terms of building space

7. Has aluminum foils reinforced on both sides, giving the product a beautiful appearance which is also corrosion resistant.

8. Easy assembly, rapid installing & low maintenance to save costs.

A typical Polyurethane duct panel is made from rigid materials which are both lightweight and easy to fix. Similarly, custom and uniquely shaped ducts can be fabricated for the user on request.

The construction work typically starts with tracing of the product’s duct outline onto an aluminum pre-insulated panel, then parts are carefully cut at 45 degree angle and bent if necessary to obtain the desired fitting design. Some tape can also be applied on seams where external surface of the duct has been sliced. There are a variety of unique flanges available to suit different installation requirements, plus all internal joints have been sealed with special adhesive to prevent leakages.

Among the different types of rigid polyurethane duct panel models available, the new water-formulated panel really stands out. In this particular make, the foaming procedure is obtained by using water instead of CFC, HFC, HCFC or HC gasses to construct the product.
