A flat roof with a warm roof design is a popular construction method that impresses with its specific construction and functionality. With this type of roof, the thermal insulation is placed above the load-bearing components, such as the timber ribbed roof from Openly.

In addition, a waterproofing layer is installed to protect the roof from the weather and act as a water-repellent layer. This waterproofing can consist of various materials, including bitumen, plastic membranes such as PVC or TPO and elastic sealing materials.

The strategically placed insulation on the top layer keeps the heat inside the building, helping to increase energy efficiency while reducing heating costs.

The warm roof design also offers the advantage of preventing moisture from penetrating the load-bearing components, as these are reliably protected by the insulation. This significantly minimizes the risk of mould growth and damage to the roof structure.

As the insulation is above the load-bearing layers, the roof space can be used effectively. This opens up numerous possibilities, whether for the installation of technical systems, such as the PV system at Openly Valley Widnau, or the creation of usable areas such as roof terraces or gardens.

Warm roofs are also characterized by their ease of maintenance. The easily accessible seal and robust construction make it easier to care for and maintain the roof.
