In the van class
All Malibu vans are insulated on the inside of the roof and the living area floor panel with a 20 mm thick RTM hard foam core. The material provides lifetime insulation, since it is water repelling and therefore does not absorb moisture. The RTM hard foam has a high degree of heat insulating capability. It therefore provides protection from heat in summer temperatures, and insulates against the cold in winter. The side walls and main body frame members are also elaborately lined with polyurethane insulating mats in the Malibu Van in order to prevent cold bridges. It is therefore hardly surprising that the Malibu vans are among the best-insulated vans in their class.
