Allianz Arena, Munich, Germany

Properties of ETFE in architectural structures:

ETFE (Ethylene Tetrafluoroethylene) is a lightweight and transparent fluoropolymer that has gained popularity in architecture. Here are some of the architectural benefits of ETFE:

Transparency: ETFE is highly transparent, allowing ample natural light to enter buildings and spaces. This feature helps create a bright and pleasant indoor environment, reducing the need for artificial lighting during the day.
Lightweight: ETFE is significantly lighter than traditional building materials like glass. This lightweight property allows for the creation of large, open, and airy spaces without the need for heavy structural support.
Design Flexibility: ETFE can be fabricated into various shapes and sizes, including domes, cushions, and complex geometric forms. This design flexibility enables architects to realize innovative and creative architectural concepts that may not be feasible with conventional materials.
Energy Efficiency: ETFE’s transparency allows for efficient solar gain, contributing to passive solar heating in colder climates. In warmer climates, ETFE’s heat management properties can help reduce cooling loads by allowing excess heat to escape.
Thermal Insulation: ETFE cushions or layers can be designed to provide effective thermal insulation, reducing heat transfer between the interior and exterior of a building. This insulation property contributes to energy efficiency and occupant comfort.
Durability: ETFE is highly resistant to weathering, UV radiation, and environmental pollutants. It doesn’t degrade or discolor easily over time, making it a durable choice for architectural applications.
Self-Cleaning Properties: The smooth surface of ETFE prevents dirt and debris from adhering strongly. Rainwater can help clean the surface, reducing maintenance requirements.
Acoustic Properties: ETFE cushions can provide sound insulation benefits, helping to control noise levels within a space. This is particularly valuable in noisy urban environments.
Cost-Effective: While the initial installation cost of ETFE systems can be higher than traditional materials, the lightweight nature of ETFE can lead to cost savings in terms of reduced structural requirements and simplified installation.
Sustainability: ETFE’s energy-efficient properties, ability to enhance natural lighting, and potential for recyclability contribute to its overall sustainability profile.
Iconic Structures: ETFE has been used in the construction of many iconic architectural landmarks around the world, such as the Eden Project in the UK and the Water Cube in Beijing. Its unique appearance can make buildings stand out and become recognizable symbols.

In summary, ETFE offers a range of architectural benefits, including transparency, lightweight design, energy efficiency, durability, and versatility. Its unique properties have allowed architects to push the boundaries of design and create innovative and sustainable structures that engage with the surrounding environment.

Holscot Patented Modular ETFE Panels

All of the above listed architectural structures utilise inflated ETFE pillows. This requires constant pressure and has ongoing maintenance and cost implications.

Being specialists in Fluoropolymers, Holscot looked at a way to offer a simple modular solution without the need of constant pressure that would suit installations big and small.

In a novel development, we can now offer a modular system (UK Patent Application 0905286.1). This allows double (or single) glazed panels in ETFE or FEP (treated or untreated) to be retro fitted as glazing to most applications including glass-houses, green-houses, or supplied for a new construction.

This novel concept opens up a wealth of new and exciting possible architectural applications e.g. atriums in commercial and public buildings, commercial and domestic green-houses, glass-houses.

Due to this being an emerging product, we encourage you to contact our sales team with your project information, where we can assist you in your enquiry.
