NOWOFLON® ET 6235 Z-IRETFE HEAT ABSORBING FILM

ETFE ARCHITECTURE

NOWOFOL OFFERS AN INNOVATIVE COLLECTION OF FLUOROPOLYMER FILMS FOR USE IN MODERN ARCHITECTURE WITH THE INTRODUCTION OF THE ETFE FILM SERIES NOWOFLON® ET 6235 Z.

BUILDING MATERIAL OF THE FUTURE – ETFE IN ARCHITECTURE

Light and UV-permeability, flame resistance, and the self-cleaning effect

are the most important properties which this material offers. All products in this

series are certified in accordance with DIN EN 13 501-1 and are classified as

flame resistant/self-extinguishing.

While the film is extremely light weight, it can handle large weight loads making

it an all-around high performance item. The durability and longevity of this

product offer an economic advantage. In addition, ETFE is almost completely

recyclable, making it an important part of sustainable building practices.

NOWOFLON® ET 6235 Z-IRETFE Heat Absorbing Film

NOWOFLON® ET 6235 Z-IR – ETFE HEAT ABSORBING FILM

NOWOFOL ET 6235 Z-IR film is the first of its kind worldwide.

It demonstrates tremendous technical characteristics: The infra-red

rays which are responsible for heating up the covered area are actu-

ally absorbed by the film, buildings stay cool longer. There are many

positive outcomes to this. Geographical areas never before conside-

red as candidates for the use of ETFE enclosures can now be viable

customers, creating both economic and ecological advantages.

Transparency and mechanical characteristics remain exceptional.
