DISCONTINUOUS PUF PANELS USING CYCLOPENTANE AS A BLOWING AGENT
[CODE NO.3690]
Thermally insulated composite building elements for roof and wall cladding in buildings, thereby forming the building envelope. They consist of an inner and outer galvanised sheet metal cover, coated on one side. They are manufactured in continuous production plants. The application is in industrial construction i.e. construction of industrial halls and cold storage facilities. Sandwich panels are also suited for other fields of application.
Sandwich panels are by now in common use as cladding elements in the building industry, creating building envelopes and partition walls. They fall under the class of composite elements and consist of an insulating foam core and a metal layer on either side, solidly glued to the core. The core is usually made of polyurethane foam (PUR) or mineral fibre wool (MIWO). Sandwich panels with a polystyrene core are also available, however. The sandwich panel has a high load-bearing capacity and is very rigid - due to the bonding (bonding or adhesion) of the covering layers to the shear-resistant core. The core simultaneously lends the building envelope excellent thermal insulation properties. Sandwich structures are quick to install and are used mainly for roofing and walls for industrial, office and administration buildings, as well as for cold storage and freezing units. Sandwich panels are of late being thoroughly tested for application in residential housing.
Polyol is a polyhydric alcohol, Containing three or more hydroxyl groups. Polyurethane systems Comprising polyol and isocyanates used for thermal insulation for Refrigeration.
Polyurethanes are addition polymers obtained from the chemical reaction of an polyol and an isocyanate, which occurs readily at room temperature. Major polyurethanes products i.e Rigid low density polyurethane, foams are the most efficient Šcommericially available insulation material.
