Flexxodomer - Double Membrane Biogas Roof
The Flexxodomer – DOuble MEmbrane Roof and thus DOMER – is a double layer or double membrane biogas roof that is often used in the biogas industry. The biogas roof is extremely suitable for silos where biogas is stored and/or where sustainable energy is generated. This double membrane roof can be used for biogas installations with a gas motor as well as a gas cleaning installation. The characteristic convex shape combines a maximum gas storage volume with an optimized shape for external influences such as wind and snow. In addition to this convex shape, a rectangular design is also possible. The Flexxodomer has been designed by Flexxolutions to ensure a maximum lifespan in all circumstances and is therefore extremly durable for our customers. We realise this by using the best materials on the market, a bi-axial design, tested components and by certified production and assembly.
- Available and successfully realised in diameters from ø2 to ø50 metres.
- Delivery always includes support construction, desulphurisation net, edge clamping, visual gas volume meter and support air system.
- Rectangular available up to 40*70 meters, for other dimensions ask our sales manager.
- The Flexxodomer can be supplied as a thermally insulated roof. Standard as single thermal insulated (HR+) or optionally as double thermal insulated (HR++) air blown roof.
- Standard foil; polyester fabric with 2-sided PVC; 4,000 N/5 cm (900 g/m²). The foil that is used in our products is extremely stable in shape, it has a breaking strength of 8000 kg per linear metre produced by a West European supplier. Stronger foil possible if desired or needed.
- Alternative foils for gas membranes such as fPP, Alcryn, N-PVC are available if required or requested.
- Standard operating pressures from -0.5 to +3.5 mbar. Higher pressures possible if required.

- The designs of our covers are approved in all countries in Europe. Standard according to German TI-4, according to TRAS-120 is possible on request.
- In standard execution the roof has a spherical shape with a clamping system on top of the wall. We can also supply other shapes such as pointed roofs and membranes for the `Schlauch` system.
- Matching overpressure and underpressure valves and various types of electronic gas volume meters are available as an option.
- Design optimised for no or minimal biogas loss in case of sudden sun appearance.
- Support construction standard designed for 85 kg/m² of snow load.
