Our Roof Constructions at a glance

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
 
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 from dipping into the substrate when pressure drops during operations
  • Fixing using stainless steel fixing profiles at the tank edge
  • Central support made from stainless steel 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
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
