Case Study
Airport ETFE Roof — Illustrative Case-Study Brief
A lightweight ETFE roof concept for airport concourses that prioritises daylight, visual openness, and coordinated engineering with the terminal structure.
Overview
Project Brief
Approved Facts Only
Airport ETFE Roof Project
This brief outlines how an ETFE roof can support a modern airport passenger journey through bright, weather-protected public space. Content is educational and does not represent a named client delivery.
ETFE role
ETFE cushions and film panels provide a translucent roof plane that can be patterned for solar control and paired with steel or cable primary structure.
Outcome focus
The illustrative outcome is a brighter terminal roof language with clearer coordination paths for structure, MEP, and airport operations—without claiming measured performance.

Brief
Design Challenge
Airport roofs must balance daylight, weather protection, maintainability, and phased construction around live operations—typical for this sector.
Challenge
Daylight without glare discomfort
Passenger halls need generous daylight while limiting harsh glare on screens and seating zones during peak sun angles.
Approach
Layered film and frit strategy
Combine cushion depth, selective printing, and orientation studies so daylight feels even rather than harsh—guided by project-specific simulation.
Challenge
Long-span roof weight
Large concourses often favour lighter envelope options so primary structure and foundations stay efficient.
Approach
Cushion roof on efficient framing
Use ETFE cushions on a steel or cable grid sized with the structural engineer, keeping spans and edge details within the coordinated design.
Challenge
Phased works near live operations
Airport programmes commonly require installation sequences that protect passenger flow and airside constraints.
Approach
Sequenced installation planning
Plan module deliveries, temporary weather seals, and access routes with the contractor so roof works align with operational windows.

Technical Highlights
Technical notes below are educational guidance for airport ETFE roofs—not certified performance claims for a specific site.
Film build-up
ETFE films used in architecture are often in the approximate 100-300 micrometre range per layer, selected per system design rather than as a universal thickness.
Cushion thermal role
Air cushions create multiple film layers with air gaps that can improve insulation relative to a single film—exact U-values depend on tested build-ups and project conditions.
Daylighting intent
Translucent roofing can reduce reliance on daytime electric lighting in concourses when coordinated with glare control and interior finishes.
Sustainability
Lightweight translucent roofs may support material efficiency and daylight strategies; whole-life benefits should be assessed within the project sustainability framework.
Safety & compliance guidance
Fire behaviour, wind resistance, and egress interfaces depend on the tested system, supporting structure, and applicable codes—not generic film statements.
Materials & specification note
Specify film layers, printing, inflation controls, clamps, and warranties through coordinated architectural and specialist performance documents.

FAQ
Frequently Asked Questions
What is ETFE in an airport roof context?
ETFE is a lightweight translucent fluoropolymer film used in single-layer or multi-layer cushion roofs. At airports it is typically considered where daylight and low self-weight matter.
Air cushion versus single-layer ETFE?
Cushions use multiple films with controlled air pressure and can offer better thermal layering; single-layer suits canopies or simpler spans. Selection follows the brief and engineering.
What does the design process usually include?
Briefing, structural coordination, daylight studies, detailing, fabrication drawings, and sequenced installation planning with airport stakeholders.
How long does installation take?
Duration varies with roof area, access, weather, and whether the terminal remains operational. Programmes are site-specific rather than fixed templates.
What maintenance should operators expect?
Typical care includes inspection of clamps, cushions, and drainage, plus cleaning access planning. Inflation systems need routine checks per manufacturer guidance.
Can ETFE roofs handle wind and weather?
When engineered for local wind, rain, and temperature conditions with appropriate structure and detailing, ETFE systems are widely used outdoors. Performance is project-specific.
Do you collaborate with airport architects?
Yes—AAKS Architecture works with architects, engineers, and contractors to align ETFE roof concepts with terminal operations and design intent.
How can we request a quotation?
Share drawings, zone priorities, and programme notes via the contact channels on aaksarchitecture.com for an illustrative scope discussion.
Which airport sectors suit ETFE best?
Concourses, connectors, atria, and skylight bands are common candidates; airside hangars and specialised zones need separate technical review.
What about fire performance?
Fire behaviour depends on the tested system assembly and local codes. Do not rely on generic film claims—confirm with project fire consultants and certified data.
