Products & services

PREFALZ
PREFALZ offers numerous options in terms of colour and shape. Thanks to the aluminium material, it is more supple than most comparable folding materials and is thus particularly easy to work with. With its low weight of between 2.2 and 2.3 kg/m², depending on the tray width, PREFALZ is suitable for roof renovations as well as for new buildings, as it adapts perfectly to the different building methods. It can also be expanded with the wide range of PREFA system accessories. The PREFALZ roof system is 100 % compatible with PREFALZ solar modules. These are available in two sizes and enable optimal integration into the roof surface without any roof penetrations. An efficient and sustainable solution for producing your own electricity.

R.16
PREFA aluminium roof tiles stand for the highest standard of quality, ensuring durability and stability. With the R.16 roof tile, PREFA has developed a stripped-down roof design that leaves plenty of room for creating unmistakeably unique architecture. Regardless of the size and shape of the roof, the PREFA R.16 roof tile gives creativity plenty of space to achieve attractive, unmistakably unique solutions.

DS.19
The DS.19 roof shingle is not only a visual highlight, it can be installed starting at a roof pitch of only 17 degrees, setting new standards in this product segment. At 480 × 262 mm, the DS.19 is slightly larger than the classic PREFA roof shingle and can therefore be installed even faster and more efficiently. Only eight pieces of DS.19 are required per m², and that with a (light) weight of just 2.75kg/m².

Rhomboid 44x44
The large format of the rhomboid roof tile 44 × 44 gives the building a particularly elegant and modern appearance. Weighing only 2.6 kg/m², it is not only extremely lightweight, but the integrated fastening strips also enable a quick and thus more cost-effective installation. Only approx. five rhomboid roof tiles are required for one square metre. This also saves time. Thanks to the flat lock system and the well-distributed fastening, the rhomboid roof tile 44 × 44 is extremely storm-proof and weather-resistant.

Ripple profile
Modern façade design needs space for creative and innovative ideas. The PREFA ripple profile gives you flexibility when implementing your ideas. The PREFA ripple profile, made of 2 mm-thick, extruded aluminium alloy, ensures maximum shape retention and resistance even under extreme strain. The fine material structure and concealed fastening create an elegant appearance — the ideal material for architectural projects designed to last for generations.

Serrated profile
Bang on trend: the PREFA serrated profile is a modern façade profile made of extruded aluminium — the ideal combination of technology and architectural design. Due to the special aluminum alloy, even sensitive areas on the building are permanently and durably clad.

Siding.X
For the development of the stylish PREFA Siding.X façade panels, the sleek and classic look of the popular PREFA sidings was combined with distinctive vertical and horizontal edging. Just like the PREFA sidings, PREFA Siding.X is a high-quality façade element made of aluminium that is installed as a non-bearing, rear-ventilated façade. Whether it is installed vertically, horizontally or diagonally, with cross bracing or an irregular pattern, the Siding.X façade panel will lend your façade a modern and attractive surface finish. For an even greater degree of personalisation, the stylish façade can be installed with or without a shadow gap. If you want a truly unique façade with an eye-catching and high-quality finish, look no further. Siding.X is available in a range of widths and colours, which can be combined however you like. What sets the Siding.X panels apart is the edging on each individual façade element. This boosts stability while giving the façade a unique and distinctive look. Thanks to its irregular surface structure, the façade catches the light in different ways to reveal all the nuances in its colouring. Now you can enjoy a new façade with a stylish and unique appearance.

Siding
PREFA façade sidings are classic elements of both traditional and modern façade design. These high-grade aluminium façade panels can be installed vertically, horizontally or even diagonally, and take the form of a non-bearing, rear-ventilated façade. This means that there is space for air to circulate between the supporting structure and the PREFA aluminium façade.

PREFABOND
The PREFABOND aluminium composite panel is the ideal façade cladding not only for large areas, but also for small ones — it not only looks great but is also extremely durable thanks to a special combination of materials. It is also highly resistant to corrosion and weather, and boasts high deflection stiffness and shock resistance. It also offers great design freedom with all the advantages of rainscreens. PREFABOND consists of two aluminium sheets which are fusion-bonded to both sides of an FR core (fire retardant). This connection is particularly robust due to the chemical and mechanical fastening. The aluminium composite panel thus ensures constant flatness and stability on all surfaces. The aluminium composite panel is suitable for façade design and many construction measures: Ventilated façade constructions Cladding of balconies Indoors: door panels, modular partitions, floor plans

Roof drainage
Good for the environment The PREFA aluminium drainage system is the best choice from an ecological point of view too. This is because aluminium does not release harmful heavy metal ions into the sewage water when gutters and pipes are constantly flushed out with rainwater, as is the case with conventional materials.

Flood protection solutions
Optimum protection with the semi-mobile PREFA flood protection system. Steadily mounting average temperatures are increasingly creating extreme weather conditions. The unpredictable threat Floods can always occur very suddenly and cause enormous damage. Due to climate change, streams and rivers are increasingly overflowing their banks. In addition to more general flooding, regionally-occurring heavy rainfall and melting snow are tending to cause more and more problems for home owners, even in areas that are located away from rivers. Therefore, it is particularly important in regions at risk to protect yourself from these forces of nature ahead of time. With the partially mobile PREFA flood protection system made of lightweight, robust aluminum profiles, you can offer your home maximum security. The special aluminium profiles are ideally suited for effectively closing windows, doors or gates as well as protecting landscaped areas close to the shore or adjacent areas.

Solar RoofTile
Roof system with integrated solar panels: the PREFA solar roof tile protects your house and produces electricity at the same time.

PREFALZ Solarmodule
The sturdy, durable glass-glass solar modules were made especially for the popular PREFALZ roof system and they fit perfectly into the typical double standing seam design.
