Phenolic foam board is considered one of the best material for thermal insulation.It has over 90% closed cell formation, giving it good stability.Phenolic foams come in varying densities in the range of 35 kg/m³ to 200 kg/m³. High density varieties such as insulation boards have good strength and are suitable for floor insulation.The most common blowing agent used in phenolic foam insulation is ‘Pentane’. This is used to comply with EC regulation, because it is CFC and HCFC free, has no ozone depletion potential and low global warming potential. Pentane is a hydrocarbon.
Alu foil phenolic pre-insulated duct panel is accomplished by following a standardised procedure. The process is the same regardless of the shape of the duct element: tracing, cutting, gluing, folding, taping, flangeing & reinforcement and sealing.
Alu foil phenolic pre-insulated duct panel is widely used in the ventilation systems of central air conditioning units in hotel, supermarket, airport, stadium, workshop, food store, industry and so on.
