Why ETFE
Roof vast spaces in a fraction of the weight.
ETFE opens up forms, spans and daylight that conventional glazing can't reach — while cutting structure, carbon and maintenance.
The nine pillars
What ETFE does better.
01
Lightweight
~5 kg/m² system weight, a fraction of glass, so you need far less supporting steel.
02
Large spans
Cover huge areas with fewer structural elements; ideal for atria, arenas, transport hubs.
03
Daylight
Transmits more natural light than most glazing; brighter, healthier interiors, less artificial light.
04
Unique forms
Adapts to curves and freeform geometry that would be costly or impossible in rigid glass.
05
Sustainability
Recyclable, low material use, lower embodied carbon; supports LEED, BREEAM and DGNB.
06
Durability
UV-, weather- and pollution-resistant; decades of performance.
07
Low maintenance
Dirt doesn't adhere, rain self-cleans, single cushions can be replaced individually.
08
Solar control
Custom frit printing and multi-layer cushions tune daylight, glare and heat gain.
09
Fire safety
Classified B-s1, d0 to EN 13501-1: limited combustibility, low smoke, no flaming droplets.
ETFE vs glass
An honest comparison.
Lighter → smaller structure. Less steel, lower cost, lower embodied carbon.
Larger free spans + design freedom. Curves and geometries glass simply cannot match.
Faster to transport and install at scale.
Honest caveat — ETFE is acoustically transparent. Superb where you want less reverberation (malls, pools, schools); less suited where high sound separation is essential.
Sustainability
Recyclable. Low embodied carbon. Certification-friendly.
ETFE supports LEED, BREEAM and DGNB. Lower material use, longer service life, and a roof system that helps daylight do the work of electric light.
