Index also produces prefabricated foamed polystyrene insulation already coupled with a membrane for refurbishing various typologies of prefabricated roofs. The prefabricated elements are produced on request in different forms, thicknesses and compressive strenght and are the result of close collaboration with the installer and/or the prefab manufacturer. Please feel free to contact us for the best solution to your problem! We can do a feasibility study and make you an offer. One or more elements prepared with cuts and chamfers can be produced so they can be sent to follow the shape to be covered. The joint between the elements is obtained by leaving the waterproofing membrane projecting on one or more sides of the panel.
