HOTROCK materials for flat roofs can be laid not only on a concrete base, but also on a trapezoidal sheet.
The flat roof system with this solution consists of two layers of heat-insulating materials HOTROCK. Lower layer that fits less directly on the trapezoidal sheet, less dense HOTROCK RUF N and the top layer is denser HOTROCK RUF V. Its task, in addition to retaining heat, also includes redistributing the external load on the lower insulation layer. Both thermal insulation layers are attached to the base of the trapezoidal sheet using a special telescopic terel fasteners.
This solution has its advantages. First, the process of installing the roof is accelerated. Secondly, you do not need to build a screed, wait until it hardens and dries, which also speeds up installation. Third, the absence of a screed reduces the load on the building structure.
The HOTROCK system is designed for use in prefabricated buildings. It has excellent mechanical strength and excellent thermal insulation performance. Its total weight is small. Among the advantages, it should also be noted fast and uncomplicated installation.
