FLEXXOCOVER
Silo cover with gastight inner membrane
A silo roof with a lung, also called a gas-tight inner membrane, is suitable for (bio)gas storage. This Flexxocover consists of two membranes. The inner membrane provides the gas-tight seal and thus determines the variable gas volume. The outer membrane serves to keep the actual gas storage volume free of weather influences such as UV radiation, rain, snow and wind load. The Flexxocover silo cover with gas-tight inner membrane is designed to ensure maximum service life and therefore optimum payback for our customers in all circumstances. We make this possible by choosing the best materials, by applying tested components and by certified production and assembly. In addition to this version, the Flexxocover is also available in a gas-open version and in a gas-tight version with a single membrane.

why the flexxocover with lung and not a regular silo roof with gastight inner membrane?
- The Flexxocover with lung has been successfully designed on hundreds of tanks and placed without defects in diameters between ø12 and ø40 meters. This broad experience ensures that we realise the best silo roof for you.
- In hundreds of positions, we apply reinforcements of the roof to protect sensitive areas from wear and tear. The combined effect of these reinforcements ensures that the silo roof can last much longer. Would you like to know what such a reinforcement looks like? Then click here!
- 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).
- We manage the entire process from design and production to assembly (under KIWA K73883 and ISO-9001). This allows us to deliver maximum quality to you.
