Engineered Membrane Fabric for Flexible Biogas Storage Structures
A professional gas holder membrane is not ordinary waterproof PVC fabric. It must balance gas retention, tensile strength, seam reliability, chemical exposure, weathering resistance, surface durability and fabrication compatibility.
What Is a Gas Holder Membrane?
A gas holder membrane is a reinforced flexible coated fabric used to form the gas storage, protection, sealing or pressure-control layers of membrane gas holders and biogas storage structures.
For Double Membrane Gas Holders
In a double membrane gas holder, the outer membrane usually provides weather protection and structural form, while the inner membrane forms the flexible gas storage chamber. Depending on design, a bottom membrane or tank sealing area may also be required to support anchoring and gas containment.
For Biogas Storage Projects
Gas holder membranes are used in anaerobic digestion, municipal wastewater treatment, agricultural biogas, food waste treatment, landfill gas recovery, industrial odor control and renewable energy projects where stable low-pressure gas storage is required.
Outer Membrane
- UV and weather resistance
- Wind and snow load direction
- PVDF or lacquered surface option
- Dirt release and clean appearance
- High-tenacity polyester reinforcement
Inner Membrane
- Gas containment direction
- Reduced gas permeability target
- Methane and CO₂ exposure direction
- Flexible movement during filling
- Reliable seam welding behavior
Bottom Membrane
- Foundation sealing support
- Dimensional stability
- Anchoring compatibility
- Moisture and condensate resistance
- Project-based thickness selection
Performance Advantages of DERFLEX Gas Holder Membrane Fabric
Buyers comparing gas holder membrane suppliers usually care about gas tightness, coating formula, welding behavior, outdoor durability, project documentation and repeat supply consistency.
Gas-Tight Inner Membrane Direction
DERFLEX can develop coated fabric direction for gas-contact layers where reduced gas permeability, seam reliability and flexible movement are critical for stable gas storage.
PVDF Outdoor Surface Option
PVDF surface treatment can improve UV resistance, weathering performance, dirt release and long-term appearance retention for exposed outer membrane applications.
High-Tenacity Polyester Base
Reinforced polyester fabric helps provide tensile strength, tear resistance and dimensional stability for large fabricated membrane panels.
Professional Welding Compatibility
Material structure can be matched with HF/RF welding, hot-air welding or hot-wedge welding according to the buyer’s panel fabrication equipment.
Chemical & Moisture Resistance
Biogas environments may include methane, carbon dioxide, hydrogen sulfide, moisture and condensate. DERFLEX helps select coating direction based on actual exposure.
OEM Project Customization
GSM, thickness, width, color, surface finish, FR, UV, anti-mildew, anti-wicking, labeling, packaging and repeat-order specifications can be customized.
Gas Holder Membrane Specification Direction
Final data should be confirmed according to gas holder diameter, storage volume, gas pressure, membrane layer, wind load, snow load, gas composition, installation method and welding process.

How to Select Membrane Fabric for Gas Holder Projects
A clear purchasing brief helps reduce sampling time and allows DERFLEX to recommend a more practical gas holder membrane structure.
Define the Gas Holder Type
Confirm whether the project is tank-mounted, ground-mounted, dome cover, flexible gas bag, lagoon cover or custom OEM system.
Confirm the Membrane Layer
Outer membrane, inner membrane, bottom membrane and replacement membrane have different priorities and should not always use the same formula.
Share Project Conditions
Provide tank diameter, storage volume, gas pressure, wind load, snow load, gas composition, project location and expected service environment.
Match the Welding Method
Share whether the membrane panels will be fabricated by HF/RF welding, hot-air welding, hot-wedge welding or another process.
Approve Sample & Specification
Confirm GSM, thickness, width, color, surface treatment, coating direction, testing requirements, packaging and repeat-order tolerance.
