Roof panels made from sheet metal are well suited with their properties such as stability, low weight and corrosion resistance. However, other properties such as low insulation values and noise generation must be adapted to the intended use through insulation and insulation.
Aluminum or titanium zinc
While aluminum was almost exclusively the metal sheet material used for roof panels in the past, a good alternative has been added after the development of titanium zinc.

Aluminum has good corrosion resistance due to its anodization, but must be colored in a complex process if the color is to be durable and UV-resistant for years.
Even after many years, titanium zinc shows hardly any discoloration or bleached spots and is priced in the same range as aluminum. Titanium zinc is heavier than aluminum and deforms less when it is warm, for example.
Properties and isolation
Two decisive properties of sheet metal roof panels must be reduced or eliminated when used on roofs under which there are inhabited and heated rooms.
- The large amount of noise generated when it rains does not play a role in the tool shed, garden shed or above the carport; in inhabited buildings the noise is clearly audible.
- Sheets a few millimeters thick have little thermal insulation and allow relatively large amounts of waste heat, which can only be compensated for with increased heating and energy consumption.
Insulation and insulation layers in a simple design or in the form of sandwich roof panels act on both properties. The rigid polyurethane foam is usually applied to the sheet metal and develops its effect according to its strength.
