Hardly any roof system meets as many different requirements as a multi-skin metal roof system with standing seam profiles. The profiles are self-supporting and are installed without penetrating screws, which would puncture the water-bearing layer. Variable panel lengths – well over 100 metres if required – avoid end laps in the roof area and reduce the risk of leaks. Connections to skylight domes, for example, are permanently welded into the standing seam roof system. Aluminium, the material used, is very resource-efficient as it is obtained mainly from recycled material. It can still be recycled decades after the end of the life of the building.
As a material for the standing seam roof, aluminium is very resistant to corrosion and weather but also easily deformable. With this formability, in combination with BEMO's unique production technology, the BEMO system stands for flexible adaptability of metal roofing to almost any building geometry.
Various roof structures can be chosen, always designed to meet the needs of the building. Very good thermal transmittance values of < 0.15 W/(m²K) can be achieved with the standing seam roof. Double-skin metal roofs from BEMO are ideally suited and almost without alternative for high sound insulation requirements. We achieve a sound reduction of >50 dB for special roof structures.
In the field of roof renovation or even in complex constructions, there are always considerable construction tolerances that can be largely compensated for with one of our BEMO substructure systems. The variety of colours, surfaces and materials such as aluminium, zinc, copper, steel and stainless steel for standing seam roofs allows maximum flexibility in design.
Internationally tested - Made in Germany! Independent international tests and approvals, e.g. by the DIBT (German Institute for Building Technology) in Germany, the BBA in the United Kingdom or FM-Global in America, document the quality and function of the BEMO metal roof system.
BEMO standing seam profiles guarantee maximum safety in roofing, even for large, flat pitched roofs and special shapes. A standing seam roof system meets the highest structural and acoustic requirements. It adapts to almost any form of building. The visual design freedom of metal roofing is almost limitless due to the free choice of profile shape, material and colour. Installation is done without penetration by interlocking on special standing seam brackets.
N 50 – with 50 mm seam height and variable profile widths. This profile has a delicate and aesthetic appearance and is often used for smaller roof areas such as mono-pitch roofs and residential buildings, as well as in industrial roofing without high snow loads.
N 65 – with 65 mm seam height and variable profile widths. This profile is ideal for flat sloping roofs due to the high seam. It is further distinguished by its very good load-bearing capacity and therefore good static values.
VF 65 – with 65 mm seam height and variable profile widths. When used on rigid insulation and timber boarding, the profile covers the entire surface. A special moulding accommodates the geometry of the bracket foot without imprinting.
BEMO's standing seam system BEMO-MONRO® is the patented system that makes flexible adaptability of metal roofing to almost any building geometry possible. The result: Each panel of a free-form building is unique. The metal panels are shaped based on exact 3D survey data in just one work step. The dimensions of the building are recorded with millimetre precision.
Generally, the MONRO® system is combined with a substructure which allows an adjustment in three dimensions. Unevenness in the supporting structure is no longer a problem, as it can be compensated quickly and easily with the standing seam system. Based on a 3D scan of the supporting structure, BEMO 3D construction plans the system ready for assembly.
Special conical profiles are ideal for larger circular and conical buildings. With a minimum width of 100 mm and a maximum coverage width of 800 mm, almost any requirement can be met. Finally, the standing seam sheets are precisely formed in just one operation. This avoids time-consuming cutting on the object and the standing seam system is easy to use.
The special BEMO profiles are also available in a curved shape and in various materials.
We realise flowing building forms with curved standing seam panels. A second production step, often performed to measure on site with our mobile production facilities to optimise freight costs, gives the BEMO standing seam panels a rounded shape.
The curving can be either concave, convex or concave-convex – the standing seam sheets can be curved to the smallest radii. Minimum radii of less than 800 mm are feasible for us, depending on the material and profile.
All BEMO profile variants are suitable for subsequent curving. The functional safety of the products remains guaranteed even when curved. To ensure tolerance compensation, we recommend installing BEMO substructure systems BEMO-DOME or BEMO-FLEX. A 3D survey of the building form in its as-built condition is recommended, as is the use of BEMO's 3D execution design.
The monoSKY® roof system combines the structural advantages of perforated standing seam roof profiles with the transparency of the layer. The advantages when the roof is transparent: when the sun is shining, the monoSKY® roof system allows a pleasant half-shade to fall on the underlying surface due to its variable hole pattern. Harmful UV radiation is significantly reduced and filtered by the transparent layer. At night, the building roofed with monoSKY® radiates light to the outside. Different effects can be achieved by the choice of colour of the light under the roof. Moreover, the semi-transparent metal roof system offers protection from wind and weather.
The roof system is mounted on brackets as a proven standing seam roof. The transparent layer is inserted into the standing seam profiles from above and fastened without penetration using a special mounting rail. So, you can design your roof transparently and cleverly hide the fitting - for every shape of building.
The entire structure is transparent for a light spectrum with wavelengths between 435 nm and 660 nm, which are necessary for plant growth.
The free sliding movement of the standing seam sheets during thermal linear expansion is one of the most important properties of a BEMO standing seam roof. For this purpose, the roof needs halters that ensure optimum load-bearing capacity. BEMO aluminium brackets are specially designed for optimum sliding behaviour due to their chamfered corners. BEMO thermal caps TK 5 and TK 15 attached to the foot of the bracket provide thermal decoupling.
As an alternative to our aluminium brackets, GFRP brackets are suitable for a thermal bridge-free construction on the roof. Our GFRP brackets are free of highly heat-conductive components and therefore completely free of thermal bridges. As a result, the insulation thickness is significantly reduced while the effective U-value remains the same. They are distinguished by high rigidity and very good load-bearing capacity.
The 2-part BEMO substructure is perfect for uneven substrates such as concrete ceilings or old supporting structures. Here, a base profile with the geometry of a hat or U-profile is fitted. A 2nd, adjustable profile is mounted on it. Tolerances of several centimetres can easily be compensated and adjusted by changing the height. The upper profile can also be supplied pre-assembled with BEMO brackets for quick and economical installation. Besides the uneven substrates, the solution is also ideal for curves which are to be created with parallel crowned panels.
A 3D scan of the assembled lower base profiles and an evaluation of the scan data by the BEMO 3D service is recommended. As a result, you get an exact design of the necessary installation position of the upper profiles. The upper profiles can be precisely pre-assembled in the workshop.
The patented BEMO-FLEX substructure allows perfectly fitting and top-quality execution of metal roofing even with complicated building shapes and with larger construction tolerances in the structure. The BEMO-FLEX roof substructure is a segmented substructure. On top of that, the metal roof system is extremely easy to install. The roof substructure makes it possible to design a three-dimensional outer skin in simple work steps and also to compensate for large construction tolerances.
The combination of modern computational design methodology with a survey of the existing structure makes BEMO-FLEX easy to use everywhere and for all our cladding profiles in roofs and façades – also for standing seam roofs. The lower U-profiles of the FLEX-SYSTEM are mounted according to static specifications. The mounting position of the U-profiles is captured in a 3D scan. From this, we derive the necessary position and height of each BEMO halter. The upper U-rail is then pre-assembled in the workshop together with the positioning brackets and bolted to the lower U-rail in a final work step to complete the roof substructure.
Designing the roof substructure appropriately allows even very high tolerances to be compensated or new building shapes to be designed.
The BEMO-DOME substructure is ideally suited for cylindrical building shapes or those curved over two axes. The standardised system always consists of the same components and varies between round and square tubes and different brackets, depending on the design. Fastening of the roof substructure is possible on all substrates and offers a tolerance compensation of +/- 45 mm.
The BEMO-DOME substructure offers the right, highly flexible substructure solution for cylindrical building shapes or those curved in two axes. BEMO-DOME is primarily used for the façades of stadiums, silo buildings, oval towers (such as digesters) or in the transition area from roofs to façades. Whether for a rear-ventilated or non-ventilated wall structure, BEMO-DOME meets all requirements.
We recommend the use of a 3D scan as an on-site survey and BEMO execution design in 3D for this substructure system to obtain a perfect surface of the metal profiles. As a result, you get a grid design with proposed mounting points and their distance and positions from the supporting structure.
