Architectural Fluoropolymer Film Supply
ETFE Fabric for Transparent Roofs, Façades & Cushion Systems
Project-oriented ETFE film and foil for daylight-driven building envelopes—specified around system type, thickness, appearance, fabrication and delivery rather than a generic roll description.
DERFLEX supports architects, façade contractors, membrane fabricators, skylight system companies, distributors and project procurement teams with ETFE material selection, samples, printed-film discussion, roll configuration and export coordination.
Terminology that prevents wrong purchasing
ETFE fabric is a sourcing phrase. ETFE film is the material reality.
Buyers often search for ETFE fabric, ETFE membrane fabric or transparent roof fabric. In architectural use, however, ETFE is generally a non-woven film. It does not contain the polyester or fiberglass reinforcement found in many PVC, PVDF or PTFE membrane fabrics.
Material definition
What is ETFE fabric?
ETFE stands for ethylene tetrafluoroethylene, a fluoropolymer that can be extruded into thin transparent or translucent film. The film may be tensioned as a single skin, welded into two- or multi-layer cushions, or integrated into framed roof and façade systems.
That distinction matters when requesting an ETFE fabric price. A quotation for film alone is not the same as a quotation for fabricated panels, aluminium profiles, inflation equipment, structural calculations or installation. DERFLEX therefore recommends defining the material scope and the system scope separately.

Selection workflow
From architectural intent to an orderable ETFE specification
A structured sequence reduces the risk of comparing incompatible quotations or approving a film that does not match the fabrication route.
Define the system
Single layer, cable-supported skin, two-layer cushion, three-layer cushion or custom panel.
Define the appearance
Clear, translucent, tint direction, printed frit, pattern coverage and viewing conditions.
Align fabrication
Thickness, width, roll core, welding equipment, panel nesting and handling limits.
Approve supply records
Reference sample, tolerances, document list, packing marks and delivery sequence.
ETFE film directions
Choose the material route before finalising the roll
Different design goals require different optical, fabrication and system decisions.
Specification framework
ETFE fabric options for early procurement discussion
The table helps structure an RFQ. It does not replace structural calculations, a project datasheet, mock-up approval or local-code review.
| Product terminology | ETFE fabric, ETFE membrane fabric, ETFE film, ETFE foil or architectural ETFE membrane. For technical documents, identify the exact film grade and intended building-envelope use. |
|---|---|
| Material structure | Extruded ethylene tetrafluoroethylene fluoropolymer film. It is normally not a woven reinforcement fabric. |
| Thickness direction | 100 μm, 150 μm, 200 μm and 250 μm are common DERFLEX project discussion points. Final selection depends on panel dimensions, stress, print, system and engineering approval. |
| Appearance | Clear, translucent, tinted or printed. Confirm reference sample, colour tolerance, haze, artwork, print coverage and viewing conditions. |
| System type | Single-layer tensioned foil, framed skin, cable-supported membrane, two-layer cushion, three-layer cushion or project-specific multi-layer assembly. |
| Performance focus | Visible-light transmission, haze, tensile and tear behaviour, UV exposure, surface cleanliness, welding compatibility, fire test route and long-term appearance. |
| Roll supply | Width, length, core, edge protection, wrapping, labels and loading method are confirmed against fabrication equipment and transport requirements. |
| Documents | Discuss the required technical data, available test information, packing records and project documents before order approval. Document availability depends on the selected material route. |
| Commercial inputs | Quantity, sample need, printing scope, packing, destination, schedule and inspection requirements. MOQ and lead time are confirmed after specification review. |
Technical values may vary by resin and film grade, thickness, colour, print coverage, test method and finished system. Confirm the final written specification with the project engineer, fabricator and relevant approval authority.
Application planning
Where architectural ETFE fabric is commonly considered
ETFE is most compelling when daylight, low envelope weight and expressive form are central to the building concept.
Stadium & Arena Roof Zones
Transparent or translucent roof areas where natural light and a lightweight enclosure support the venue concept.
Airport & Station Envelopes
Terminal roofs, covered walkways and circulation zones requiring brightness, drainage planning and maintenance access.
Commercial Atriums
Shopping centres, hotels and public indoor streets using skylights or cushion roofs to create a light-filled interior.
Façades & Feature Skins
Single-layer or cushion façades with clear, printed, tinted or illuminated design directions.
Botanical & Greenhouse Projects
Plant-focused spaces where daylight is central and thermal, ventilation and condensation strategies are carefully coordinated.
Pavilions & Lightweight Additions
Curved canopies, entrance features and renovation-sensitive roofs where reducing envelope dead load may be valuable.
Material comparison
ETFE, glass and coated membrane fabrics serve different goals
No envelope material is universally best. The project priorities should determine the shortlist.
ETFE Film / Foil
Often reviewed when transparency, low envelope weight and free-form roof or façade expression are central.
- High daylight potential
- Single-layer or cushion systems
- Printed shading can be designed
- Requires specialist foil engineering
Glass Envelope
Often selected where rigid glazing appearance, acoustic mass and conventional curtain-wall integration are priorities.
- Rigid transparent assembly
- Established glazing methods
- Higher structural dead load
- Different replacement and access logic
PTFE / PVC Fabric
Often selected for opaque or translucent tensile roofs, canopies and shade structures rather than glass-like transparency.
- Broad tensile-roof applications
- Welded or seamed textile panels
- Different cost and service-life routes
- Strong option when clarity is not essential

FAQ
ETFE fabric questions from architects and buyers
Clear answers for material comparison, procurement and project-scope discussions.
Is ETFE fabric actually a fabric?
No in the usual textile sense. “ETFE fabric” is a common search and trade phrase, but architectural ETFE is normally an extruded fluoropolymer film or foil without a woven reinforcement. This is different from PVC-coated polyester or PTFE-coated fiberglass fabric.
What thickness of ETFE film should I request?
Early discussions commonly include 100, 150, 200 and 250 μm. The correct thickness depends on panel size, stress calculation, wind and snow actions, system type, printing, welding and the project engineer’s approval.
Can ETFE fabric be printed for solar shading?
Printed dot, frit or project patterns can be discussed. Print coverage and layer position influence daylight, glare, solar transmission and appearance, so artwork review and physical sample approval are recommended.
Can ETFE replace glass?
ETFE can be considered as a lightweight transparent alternative in many roofs, skylights and façades, but it does not reproduce every glass characteristic. Structural behaviour, acoustics, thermal targets, fire strategy, maintenance, access and local codes must be compared at system level.
Does DERFLEX supply complete ETFE cushion roofs?
This page focuses on ETFE film material, printing direction, samples, roll configuration, packing and procurement support. Complete cushion engineering, aluminium framing, air-supply equipment, structural calculations and installation should be confirmed according to the agreed project scope and specialist partners.
What affects the ETFE fabric price?
Price depends on film grade, thickness, width, quantity, colour or print, pattern coverage, sample and document requirements, packing, destination and delivery schedule. Quotations should be compared only after these variables are aligned.
