Slate is not exactly like slate!
Slate consists of natural, ecologically completely unproblematic substances of content. Therefore slate is superior to many building materials that first of all have to be produced out of different mineral components by joining them. The production of slate for roof and façade requires only one processing (i.e. formatting) with low energy expenditure, i.e. neither a binder (such as cement) nor a treatment in a kiln.
Occupants of houses with a slate roof or a slate façade live particularly healthily with this natural building material. In addition, their roof and façade do not require any special maintenance. Quality slate is considered one of the most durable roofing products of all and therefore it has a long life span. After the service life there are no disposal problems like the ones with some industrial products. Slate split and slate powder can even be used as a soil improvement, for aggregates and other products of high quality. Thus for slate the result is an ecological balance that does not have to shy away from any comparison.
Rathscheck Quality System
The Rathscheck Quality System exceeds by far the required national and European test standards and is based on many decades of experience in the production of slate for roof and façade. These resulted in a test system for assessing the worldwide slate qualities. Only the best slate deposits comply with our strict requirements.
With test methods developed by ourselves, by constantly checking our own production processes on site as well as the productions of our international strategic partner we take care of the observance of the Rathscheck quality criteria. At the same time we are supported by independent test institutions.
- Best slate only from tested deposits.
- Continuous check of the rosk qualitiy.
- Constant supervision of the production processes.
- Strict selection of the finished roofing slate.
