SANDWICH PUF PANELS
Puf panel made construction is not dependent on weather as it is pre-fabricated. Except cold storage puf panels have also some more applications as to prepare cool cabins. There are numerous residential and official purposes where cold is required for. Telephone booth, green room, school, toilet, garage, store room or gym deliberately demands cooler temperature inside. Parallelly farm houses, traffic shelter, site inspection mobile offices etc needs to be cooled as people engaged with it work on open sun and extreme heat or hours. As puf panel made cabins can reduce temperature up to 7 degrees it is perfect for these purposes. Medical vans, transports for fruits demanded cool temperature in order to preserve quality. Using minimum steel and civil work it only focuses on architectural detailing which makes it the first choice for school buildings as for laboratory where extreme heat is not allowed.
PU/PIR metal-face sandwich panels can be manufactured with the PU/PIR reaction mix is first laid down on one metal facing. During the expansion process, rigid polyurethane foam passes through a tacky phase, which enables it to form a strong bond with the facings.
The insulating effect of PU/PIR foams is much better than that of mineral wool, for example, a layer of PU/PIR ten centimeters thick has a heat transfer coefficient of around 0.25 W/m2K. A rough estimate of what this difference means in terms of energy consumption can be made based on the example of a factory building. Assuming the building has a floor area of 40X20 square meters and 10 meters high, the annual amount of heating oil saved could be roughly 3,000 litres if both the walls and the roof are insulated with PU/PIR metal-faced sandwich panels rather than panels of the same thickness based on mineral wool. Low energy consumption also results in an equivalent reduction in carbon dioxide emissions.
