Roof systems from BEMO

With the “soft” roof structure BEMO-SOFT, very low U-values on the roof of < 0.15 W/m2K can be achieved with a low structure height. The quick and easy installation of the halters directly onto the supporting shell also means that a very economical structure can be achieved. Increased fire protection requirements can be achieved by installing A1 non-combustible insulation.

With the very compact BEMO-COMPACT roof structure, the highest requirements in the area of sound insulation and year-round thermal insulation can be met, thanks to ideal insulation in the roof. Due to the two-layers of non-combustible, tread-resistant thermal insulation, it is possible to achieve a depth of up to 360 mm. This also avoids system-related thermal bridges.

The properties of the BEMO-PROMAX roof structure with insulation: maximum sound insulation, perfect summer and winter thermal insulation, and excellent protection in the event of fire. Sound insulation values of over 49 dB can easily be achieved with the insulating roof system. Simple and quick installation of the non-combustible, step-resistant insulation, as well as the fitting of the easy-to-install PROMAX rail complete the structure.

Standing seam roof systems are suitable as a safe basic system for modern, ecological green roofs and thus as a green roof structure. This green roof counteracts the sealing of surfaces. Green roofs not only provide thermal protection in summer, but also help to keep the air clean, especially in urban areas.

The system’s sedum carpet with low-growing, self-regenerating and drought-resistant plants is applied to the roof on top of our BEMO standing seam profile with integrated bead seam sealing. The result is a surface cover of delicate natural carpet with seasonally changing colours. Plants for green roofs are unpretentious, tolerate smoke and fumes, and are resistant to wind and frost. The nutrient supply comes largely from natural process cycles. Maintenance is rarely necessary for the plants. Rain run-off from the roof is significantly reduced and extends over a longer period. Most of the precipitation evaporates. Pipelines and overflow basins can be smaller. Anti-shear barriers also allow green roofing of sloped or curved roof shapes up to 10°.

Attractive drainage facilities as well as connections and terminations are tailored to suit the structure of the green roof. The aluminium surface of the profiles provides permanent protection against root penetration, while the method of fastening reliably prevents the entry of water or moisture. The service life of the roof is even increased, as the roof cladding under the sedum carpet is not exposed to any damaging environmental influences and is also well protected against physical damage. Of course, partial greening is also possible. The sedum carpet can be removed at any time without affecting the underlying BEMO standing seam roofing. And of course, every existing BEMO standing seam roof system can be retrofitted with BEMO VERT as a structure with a green roof, if the statics allow it.
