Company Profile
Dachziegelwerke Nelskamp GmbH, based in Schermbeck (NRW) is one of the biggest manufacturers of small-sized, hard roof-cladding materials in Germany. Being an independent well-established family-run business, its fast decision-making process enables it to respond flexibly to current market demands. State of the art technology, distinctive quality-orientated thinking and a personal link to craft and trade have defined the philosophy of the family business since its es-tablishment in 1926.
Being one of the few businesses in Germany to do so, Nel-skamp has been manufacturing both clay and cement roof tiles for more than 50 years. Consistent development projects lead to a comprehensive product-range: the wide range of clay roof tiling is continuously expanded with new moulds and dimen-sions.
The company has been producing concrete roof-cladding with the “Finkenberger Pfanne” tile sicne 1953. The current range of concrete roof-tiles offers real alternatives for roof architecture. With the “Longlife” surface finish, Nelskamp developed the (what is currently the most modern) concrete-tile product with regards to colour fastness and prolonged surface cleanliness. This development is being carried forward with „ClimaLife“ – which seeks to actively break down pollutants in the air.
Nelskamp is also an industry leader when it comes to large til-ing. The "Nibra® DS 5" tile is, for example, particularly suited to covering large surfaces and roof trusses and its low weight per unit reduces contamination of roof trusses which are usually covered with fibrated concrete or corrugated sheeting.
Nelskamp stores the complete range of clay and cement prod-ucts at six locations across Germany, proving their nationwide presence. A team of highly qualified specialized experts guar-antees on-site tailored consultation. In addition to this, the company also provides technical services if so desired. The package they offer is rounded off nicely with special training courses in trade and craftsmanship as well as a roofing crane and tendering service.

Roofing tile works Nelskamp, Schermbeck
Pilot projects in Duisburg, Dinslaken und Voerde: Photo catalysis neutralises harmful substances / Environmentally active building materials are current trends for houses
Duisburg. The issue of air pollution in big cities and urban areas is one of the topics discussed most in Europe. Air pollution with nitrogen oxides (NOX), benzenes and aldehydes is particularly increasing continuously. Recently the “first industrially manufactured environmentally active roof tile in the world” was presented in Duisburg. There are currently three multiple dwelling units which are roofed with the new ClimaLife roof tiles of Nelskamp (Schermbeck/ NRW). Their surface is made of micro-concrete containing a titanium dioxide, which, by means of daylight, breaks harmful nitrogen oxides, for example, and converts them into harmless substances. The rain does the rest and flushes everything away. For the whole lifetime of the roof.
“In Germany a roofing area of up to 30 million square meters is newly tiled with roof tiles made of concrete every year – a huge potential for clean air in cities and communities“, declares the managing director, Heiner Nelskamp. Especially in urban areas, where most of the harmful substances originate from the combustion of oil and gas in heating units, power plants and vehicles; a decrease of nitrogen oxide by means of roof surface area would be particularly effective. Furthermore, nitrogen oxide increases the impact on the ozone. Therefore its reduction, together with other products around the home, such as facades or paving stones, would also mitigate summer smog issues. The protected trademark “TXActive“ labelling photo catalytically active products all over Europe, guarantees the owner a “tested quality“.
In Japan the effect of the photo catalysis in reducing nitrogen oxide in the air has been successfully utilised since the Nineties. Within the framework of an EU promoted project in Italy, this was also meteorologically proven: With maximum solar radiation an NOX, reduction of up to 90 percent could be achieved within a few hours. When the weather is bad, up to 70 percent can still be achieved. This process is triggered by the ultraviolet radiation of the sunlight. Therefore the reaction also takes place when the light is diffused.
As a reactive product, small quantities of water-soluble nitrate are formed, which are flushed away by the rain. In the natural cycle of materials it is provided as a nutrient for plants, if the substance has not previously been filtered out in a purification plant.

Three large format hollows
New: "Nibra MS 5" - economical replacement tiling for large roofs
The largest Nibra surface tile thus far (“DS 5”) now has a brother: Similar to the optics of the classical double hollow grooved tile, the new Nelskamp large surface tile "Nibra MS 5" also requires barely six pieces per square metre of roof and for this reason, it is particularly economical to lay. As roofer Oliver Kortendieck, Application Technician at Nelskamp, stresses, "The 6.6kg weight of each piece reduces the load of the roof construction by up to half a tonne per 100 square meters." Above all, demand for the new model comes from the construction sector and agriculture - for large halls and barns. One of the first buildings with the new tile is in Wolfenbüttel - 600 square meters of natural red roof tiles, laid in just three days.
The double hollow grooved tiles are also common in southern Lower Saxony. They characterize many agricultural buildings as well as roof landscapes, especially in small towns and communities. In order to keep these classical optics and, if required, to lay a roof economically, the "Nibra MS 5" of the basic shape with its three hollows was reproduced.
Traditional double hollow grooved tiles typically require up to 15 pieces per square metre. With Nibra MS 5, the builder saves laying, transportation and material costs. Due to the large format, working time and wastage is reduced. In addition, through the comparatively low surface weight, the load is taken off the structure and the roof can be finished more easily.
The hollow structure makes the tile static extremely stable. A surrounding grooving provides reliable drainage of rainwater. In addition, the size of the "Nibra MS 5" has a positive impact on the penetration of rain. As Kortendieck states, "With only approx. six bricks per square metre, the number of grooves in the surface is reduced".
A pronounced head and foot groove allow a variable height overlay of up to ten centimetres. At an average covering length of 50.4cm, the potential covering length for fully connected roofs is 44.4 to 54.4cm. The tile usually has a standard roof pitch of 22 degrees. This stands in contrast to small models, where the standard roof pitch is 30 degrees.

The new roofing tile generation
“Longlife” has taken hold – permanently clean roofs set the trend / wide range of colours
For over 50 years, the industrially manufactured roofing tile has been an established feature of rooftops in Germany and Europe. With the innovative “Longlife” surface from Nelskamp, refined concrete products are experiencing a renaissance. The micro-concrete layer of the new generation roofing tile is so smooth that dirt, moss and algae are washed away immediately. Meanwhile, these “self-cleaning” pan tiles are available in a similarly broad range of colours and shapes as “normal” clay roof tiling. Due to their low energy requirements in the manufacturing process, roof tiles are seen as particularly inexpensive alternative solutions to roofing.
A roof should look like it has been freshly laid for as long as possible. As Nelskamp has established, this is something that builders increasingly wish for. If dust is deposited on the roof, algae or lichen usually establish a hold. The especially smooth, non-porous surface of “Longlife” ensures that micro-organisms do not have any opportunities for growth. As roofer Oliver Kortendieck from Nelskamp explains, “The smoother the surface, the faster the organisms will be deprived of vital moisture, and as such growth is prevented”. The micro-concrete layer is completely water-resistant, i.e. the rain can wash the dirt away completely and the roofs remain permanently clean. Special polymers ensure that the colours remain stable and do not fade.
This colourfastness is determined by the specific composition of the surface. It consists of colour pigments, fillers and binders made of polymers which make a firm connection with the substrate. Roof tiles are fully coloured throughout. As such, their colours have a strong effect. Special colours such as blue or green are available, however the classic red, brown and black are mostly laid on German roofs – approx. 70 percent.
For over 30 years, Nelskamp has carried out outdoor tests on weathering stands for all products for their colour fastness, aging and reaction to environmental influences. As such, they are also exposed to the fierce sun in the same way as storms, hail and frost. In addition, some pan tiles are covered with a dirt layer in order to scientifically investigate the natural cleansing process of rain.
Only natural raw materials (quartz sand, water, cement) are used in the manufacturing process. The production process takes place without a large expenditure of energy: sand, cement, water and colour pigments are mixed, pressed into shapes and cut to size. After setting in the dry kiln, the roof tile is water-proof and frost-resistant, i.e. virtually indestructible.
All roof tile models are based on traditional tile shapes. Above all, it has been the variants with a middle beam and a high-lying longitudinal rebated join which won recognition. The first Nelskamp roof tile the “Finkenberger pan tile” is still a strong market player mostly with an unchanged form.

“Nibra F 10” flat roof tile
28 mm adjustment range / modern interlocking joint technology
The new "Nibra F 10 Ü" accommodates the growing demand in German roof renovation. "Ü" stands for overlay tile: The particularly large adjustment range of 28 millimetres for a flat roof tile enables a high degree of flexibility when it comes to laying.
As roofer Oliver Kortendieck from Nelskamp explains, "Our roof layers wanted flat roof tiles which were adjustable so that they could work more easily." This is why the large surface tile "Nibra F 10" was developed. The "Ü" is characterised by its advantage: The 10 format now has the variable covering length of 41.3 cm ± 14 mm (preceding tile: 42.0 cm ± 5 mm). Above all, the roofing makes sanitation easy - with a standard pitch of 22 degrees as well as flat sloping roofs.
The innovative interlocking joint technology provides improved top and side notches and increased immunity from rain penetration. With the "big brother" of the F 10, the Nibra F 7, this technology allows a tile to be produced with a standard roof pitch of 18 degrees.
The tile is made from Westerwälder clay. This means that after firing it has the established clinker-brick quality of all Nibra large surface tiles with a water absorption factor of less than 3%. Overall, there are eleven different colours and shades to choose from - natural red to black glazed.
In the long-term, the "Nibra F 10 Ü" will replace the classic F 10. This is still available, and provides a guarantee that individual pan tiles can still be replaced.
