Heat radiation through the roof

Radiation from the sun can increase the heat on a flat roof surface to 80º Celsius or more. The heat penetrates via the roofing through the insulation layer to the inside, resulting in temperatures in the underlying building and/or level increasing to extreme heights (figure 1a).

By installing Roofclix® roofing elements on top of the existing roof, the sun’s radiation can no longer reach the underlying roof and thus prevents it from warming up. (Figure 1b) This can result in a heat reduction of 40º Celsius or more  . The inside temperature can be better controlled, which provides a more pleasant and comfortable work environment.

Concrete roof

A concrete roof makes it harder for heat to penetrate, and conversely also hampers the ability for internal cooling (figure 2a). The rule that applies here: what doesn’t come in doesn’t have to go out (figure 2b). This enables architects to design lighter constructions by using Roofclix® roofing tiles and achieve financial savings on building materials, labour and faster delivery times. 

A financial benefit of the Roofclix® roof is that the high energy cost for cooling (air-conditioning, etc.) in the building are diminished significantly as it costs approximately 7 times more energy to cool a building than to heat it. The benefits are clear for many commercial properties, offices, hospitals and schools etc. (figures 3a and 3b).

Low temperatures

Roofclix® roofing tiles provide extra energy savings during cold periods too. During colder periods with frost under the roof tiles a clear difference in temperature is noticeable. Measuring Results of January 2010 (frost) on the bare roof shows temperatures of -18 degrees Celsius, while at the same time under the Roofclix they show -3 degrees Celsius. Snow is also prevented from making direct contact with the roofing material, resulting in the formation of an insulating blanket above the cavity layer and creating a layer of still air that provides extra insulation (figure 4a and 4b).
