Prefabricated structures and buildings have given a new meaning to construction. With the introduction of this innovative technology, buildings and enclosures with a specific sense of purpose can be achieved and thus greater efficiency is to be gained. As practicality is the prime factor to consider whenever designing a building, the use of materials and components that enable the structure to deliver intended purpose is imperative. Pre-fabricated structures intended to be energy efficient and temperature controlled are offered envelopes of PUF insulated panels . These panels are leakproof and help maintain constant temperatures. Fig1. Insulated Sandwich Panels Insulated sandwich panels have certain specific features that make them stand out - § Cost-effectiveness § High insulation values § Fire and sound protection § Quick and easy installation § Pleasing aesthetic finishing Insulated sandw
