THUNDER draws its design inspiration from the architecture of Podhale

Unique roofs made of wooden shingles are primarily associated with the mountain landscape. However, the high cost of manufacture of traditional coverings and the insufficient resistance of wood to external factors have contributed to the emergence of many alternatives on the market.

Therefore, in response to the needs of customers seeking new, ecological, unique solutions, we introduced a modular roof panel covered with a natural stone chip coating – THUNDER. A profile imitating a traditional wooden shingle, covered with natural stone chips. Designed and manufactured in Poland.

This is a product whose quality, reliability, durability and design will appeal to demanding customers, and which creates a kind of harmony when combined with wooden construction. Its application ensures the roof’s resistance to extreme weather conditions in the time of rapid climate change. These promises are confirmed by a 60-year warranty.

The THUNDER roofing module is much lighter than ceramic tiles, so it can also successfully replace them on older roofs. Moreover, the simple assembly and connection system guarantee perfect tightness of the covering – without risk of roof leakage.


Additional possibilities in enhancing the look of the roof are provided by our original colours. This extensive colour range makes BTR Systems roofing solutions as elegant as they are full of energy and dynamics.
