Membrane Roof

• Fibre-reinforced membrane, available in green or grey
• Helps reduce emissions
• Fixing using stainless steel fixing profiles at the tank edge
• Central support made from steel with resilient special coating or as stainless steel supports
• No condensation on the tank wall due to a circumferential drip edge on the inside of the cover segments
• 2 inspection openings as standard
• Roof pitch is approx. 25°
• UV-resistant, fungicidal
• Flame retardant to DIN 4102 B1

GFK cover

• Available as self-supporting flat roof, smooth dome or ribbed dome (depending on tank diameter)
• Highly convex and high load-bearing capacity due to curved cover segments and radial rib structure
• Joints and seams with permanently elastic seals and special sealing compound
• No condensation on the tank wall due to a circumferential drip edge on the inside of the cover segments
• Screw connections completely made from stainless steel
• Opening with cover for maintenance and inspection purposes

Stainless steel roof

• Available as a self-supporting roof (depending on tank diameter)
• Joints and seams with permanently elastic seals and special sealing compound
• No condensation on the tank wall due to a circumferential drip edge on the inside of the cover segments
• Screw connections completely made from stainless steel
• Opening with cover for maintenance and inspection purposes
• Roof pitch 10° or 15°
• Possibility of introducing bushings

Double membrane roof

• Consisting of an outer membrane and a pressure-dependent inner membrane
• Supporting air supply including stainless steel housig provides pressurisation in the supporting air space between the membranes
• The inner membrane adjusts itself to the volume of the gas tank, with the outer membrane offering constant protection
• Sub-structure prevents the double membrane dipping into the substrate when pressure drops during operations
• Fixing using stainless steel fixing profiles at the tank edge
• Central support made from 1.4301 for use with liquids and 1.4571 for use with gases
• Gas fill level indicator mechanical or electric
• Suitable for use in the biogas sector
• Low methane gas permeability
