Symmetrical Cladding

with visible fixture

Cost-efficiency, smooth laying and unique aesthetics – these are the requirements of modern architecture against high insulated, ventilated façades. The symmetrical cladding is an innovative façade system developed by Rathscheck, which corresponds with these requirements and defines the natural slate façade completely new.

Owing to the low square meter weight the symmetrical cladding is ideal for façade design of big building bodies, where high cost-efficiency is essential

Cramp technique

The natural slate stones will be suspended simply with stainless steel clips into an aluminium substructure. The system is construed in a manner, that thermal expansions will be absorbed. Any slate forms up to a size of 60 x 60 cm with only 1 cm thickness allow the perfect adjustment to the building geometry.

Three natural slate colours (blue-grey, polar green and dark green) in different surfaces (natural split and polished) of the brands InterSIN®, ColorSIN® and ROCANEX® offer the designers freedom for extravagant façade designs.

This facade system allows for the use of extensive slate tiles up to 60 x 60 cm by providing a variable substructure..

The aluminium substructure of the system is laid out in such a way that it acts as a buffer against thermal expansion.

The accommodation of all current insulation thicknesses in accordance with EnEV (Energy Saving Ordinance) is guaranteed. The lower square metre weight due to the tile thickness of only one centimetre and the simple and quick assembly by hooking offer enormous potential savings.

Unlike all other slate deck types, no vertical or lateral overlapping of the tiles is required. The tiles, which are approximately one centimetre thick, are installed on the substructure with stainless steel clips and can be easily and quickly assembled.

Tiles made from slate blue InterSINslates as well as polar green ColorSINslates are provided for symmetrical coverage. Both types of slate are available with either a natural surface or a polished surface. In addition, tiles made from dark green ColorSIN® with a rough, grooved surface are provided.


For technical instructions and more detailed information, please see the installation manual for symmetrical coverage. This describes the use of InterSINslates, SIN 970 (maintenance recommendation) or ColorSIN®, CS 35 or CS 50 (maintenance recommendation), in combination with the aluminium substructure included in the delivery scope and the corresponding fastening means as a complete system. The instructions are the basis for appropriate planning and application-orientated technical solutions in normal situations. The detailed drawings shown in the installation instructions describe some standard details of symmetrical coverage.

The slate for excellent buildings.

With MONUMENTUM® we not only want to maintain a tradition but also to help shape the future. Our premium product continues the spirit of Mosel slate, which shaped the Altdeutsche Deckung for more than 200 years. Exquisite stones combine classicism with progress. MONUMENTUM® with its stone characteristics and variety of formats stands for the continuation of the classic slate covering in sophisticated architecture.

With more than 40 years of experience with selected deposits and a quality system that goes far beyond the national and European testing standards required, Rathscheck continues the Altdeutsche Deckung with Monumentum. Through strict controls, the careful selection, and precise manufacturing, Monumentum has the best test certificates in terms of water absorption and permeability, temperature change resistance and acid resistance. Every capstone that leaves the modern production facility in the northwest of Spain is a valuable unique specimen.



Vibrant beauty for the most discerning tastes.

Nature is a perfectionist. This is why our premium product, Moselschiefer®, which has matured deep under the earth for 400 million years, provides an ecological slate cladding of the highest quality.

We are fortunate to have this type of slate in Mayen. Even the Romans appreciated the durability, gloss and deep, blue-grey colour of this rugged building material and quarried it here. The slate was originally transported along the Mosel River, which is where its name originated in around 1588. Moselschiefer® is one of the world’s oldest brand names and still represents the highest quality slate.

For many generations, master builders and artisans have used Moselschiefer® to create buildings with lasting value. They perfected their art in the creation of the Old German cladding, which remains the most regal coverage format.

Today Moselschiefer® is used exclusively in gardening and landscaping. As decorative gravel in the form of slate chippings in various grain sizes, it is suitable for decorative surface design. Screening walls, masonry bricks and solid stepped bricks made of slate ensure a varied and lively overall appearance.


A material with varied facets.

InterSIN® is our brand name for blue-grey slate that has been internationally sourced. InterSIN slate is obtained from surface quarries and underground mines. It is collected with great care using the most modern technology.

Its durability makes this rugged, low-maintenance material an extremely economical commodity for roofing and façade cladding. Blue-grey slate is a high-quality, entirely natural product. Our Rathscheck quality system was developed over several decades; adherence to strict criteria and constant on-site inspections ensure the high quality standard of the various slate deposits. Slate samples are regularly subjected to numerous tests and must meet our requirements that are based on the quality of our premium MONUMENTUM® product.

InterSIN® is available in many different cladding formats. From the most economical universal cladding to many types of façade claddings and scale claddings, a suitable InterSIN® slate format can be found for any taste and any budget.

There are no limits to the individual design options. InterSIN® provides each prestige project with a unique character that lasts for generations.



Slate in natural colours.

What is the colour of courage?

Slate. A vibrant, natural stone. Produced by natural forces millions of years ago, but prized even today as a building material with perfect characteristics for roofs and façades.

Everyone knows slate – a type of blue-grey stone with a silky gloss. But did you also know that slate is available in other colours?

Depending on the configuration of the natural components, slate comes in a variety of subtly nuanced colour tones. This is why slate displays reddish or greenish hues in some locations.

ColorSIN® is the brand name of our coloured slate. The different cladding formats provide variety and colourful design options, which lend an individual character to each slate cladding.Charakter.

Just like blue-grey slate, ColorSIN® is a purely natural product with the same characteristics. It is extremely durable, robust, easy to maintain and surprisingly good value. A colourful slate cladding always has a special appeal.

Be bold. Show your colours!
