Kingspan Jindal's insulated sandwich panels are single component, factory pre-engineered systems. They are made up of rigid polyurethane (PUR), Polyisocynurate (PIR), Isophenic (IPN) or mineral wool insulation core sandwiched between twol layers of metal, one being the external weather side, and the other a pre-finished internal liner. The result is a single component solution that replaces multi-part construction.
