Application of duct panel

Category: Phenolic duct plate


  • Product overview
    • Commodity name: Application of duct panel


    HVAC insulation can be used in these systems across large-scale commercial and residential properties, including high-rise offices, apartment blocks, airports, hospitals, warehouse and other industrial facilities, ensuring a comfortable living environment.
    Effective insulation is essential for maintaining the correct operating temperature for the different parts of a system – from piping to central heating and air conditioning insulation. As these properties use a lot of energy to create a comfortable climate, working as efficiently as possible is vital.


    Phenolic should always be installed above the damp proof membrane (DPM). It is never recommended to lay them exposed directly to the ground. Long term exposure to moisture can result in facings – particularly composite ones featuring kraft paper layers – breaking down, to the detriment of the product. Phenolic insulation is susceptible to decay and causes pipework corrosion when it gets wet. Therefore, measures should be taken to prevent water ingress. Pipework should be properly installed to avoid leaks and all welds should be painted with corrosion resistant paint prior to joint insulation and casing work. Phenolic insulation systems were put in place that the industry realized it creates sulfonic acid when exposed to humidity or direct moisture, like when a roof leaks. In a short time, the acid begins to eat holes in standard painted deck and/or galvanized decks. Phenolic insulation also has a history of crumbling and easily crushes when walked on, leaving a residue on the decking. In order to prevent corrosion in this application, we would need to remove all the residue, which is not practical. But corrosion can’t form without oxygen, moisture and a catalyst. In this case, the catalyst is the Phenolic insulation residue and the sulfonic acid. So the easiest way to prevent corrosion is to use a high-build barrier type coating to stop moisture from contacting the sulfonic residue and steel.
    The amount of money you spend on insulation boards can vary greatly depending on the type, so it's important to know what you're getting before you buy. When building or renovating there are really 4 main kinds of rigid foam panels you are going to have to choose from - Polyisocyanurate known as Polyiso (PIR), Phenolic foam (PF), Extruded Polystyrene (XPS) - often called Styrofoam - and Expanded Polystyrene (EPS).
