Silo cover | GasTIGHT execution
A gastight silo roof is a cover for a silo, which is made completely gastight, virtually emission-free and also suitable as an after fermentation unit. This silo roof offers the solution for the cover obligation that applies in many European countries. Depending on your wishes, the silo cover can be fitted gastight on the inside or on top of the silo edge. This choice has an effect on the extent to which maintenance can be carried out on the cover and the silo. The Flexxocover gastight has been designed to ensure a maximum lifespan in all circumstances and is therefore extremly durable for our customers. We make this possible by choosing the best materials, by using tested components and by certified production and assembly. Ask our sales experts for more information! This product is also available in a gas-open execution.
why the flexxocover GASTIGHT and not a regular gastight silo roof?
- The Flexxocover gastight is successfully installed without defects in diameters between ø2 and ø54 meters.
- In hundreds of positions, we apply reinforcements to protect sensitive areas from wear and tear. The combined effect of these reinforcements ensures that your gastight silo roof will last much longer. Would you like to know what such a reinforcement looks like? Then click here!
- We manage the entire process from design and production to assembly (under KIWA K73883 and ISO 9001). This enables us to deliver maximum quality.
- All our metal parts that might get in contact with gas are always made of stainless steel-316 because of the minimum sensitivity to corrosion (rust).
- 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.
- For each gastight silo roof you will receive an extensive report in which all strength calculations, conditions and the resulting force on the silo wall are calculated. It is always useful to check with the silo builder, so that a maximum lifespan can be achieved.
- Our foil suppliers give a five year guarantee on the material and we give a five year guarantee on the design and processing.

VERSIONS
Attachment inside silo wall
This assembly method is often used for cost reasons.
Attachment on top of silo wall
The advantage of this assembly method is that the cover can be re-opened and closed in a gastight way during stops in the operational stage.

FLEXXOCOVER gas-open execution
The Flexxocover is suitable for concrete, element and steel silos and has been successfully assembled by us on more than 1000 tanks.
FLEXXOCOVER SILO ROOF WITH LUNG
The Flexxocover with lung is a double membrane roof. The inner membrane keeps (bio)gas inside and the tensioned outer membrane keeps out external influences.
FLEXXODOMER DOUBLE MEMBRANE ROOF
This double membrane roof is ideal as a cover for silos where biogas is stored or where sustainable energy is generated.
