Heat-heating papa is one of the most widely used insulation materials. They are used both in residential construction and in industrial areas. Its undoubted advantage is the total resistance to moisture. This feature makes it an excellent material for securing the most sensitive points of the building, such as foundations or roofs. The process of laying heat-weldable papy is easier and faster than traditional materials. They are covered on one side with a bitumen layer, which under the influence of warm from the burner melts and permanently connects the pape to the substrate. The connections of the individual belts are sealed thanks to the factory facilities placed on the papa. This solution guarantees the longevity of the insulation laid and the absence of frequent repairs or corrections. The undoubted advantage of all heat-heating paps is their wide application, in addition, they are very flexible and do not cause trouble when laying on complex surfaces. Many of them are modified by adding various polymers to them, which significantly improve their properties. It is even possible to lay this type of insulation in winter conditions. Once a well insulated surface using heat-weldable mush is protected for many years and does not require further action. These materials are an example of how modern technology enriches traditional working methods with new and innovative elements. This allows for new ways of using them.
