Membrane Architecture – Life Cycle Assessment – Environmental Impacts. Link

DEADLINE APPROACHING 20.03.2026

The TensiNet association has engaged Chemservice to collect information on the socio & economical impact of a PFAS ban and to prepare a dossier to reply to SEAC.

We do need your participation. Chemservice has prepared a questionnaire.

Return this questionnaire no later than Friday 20^th March 2026, to assure a timely development of the TensiNet response to SEAC.

Save the date - Friday 6th March from 13.00 till 14.00

Following the success of this first webinar, TensiNet has started to develop a full programme of webinars that could take place monthly around lunchtime (GMT +1).

Membrane Architecture – Life Cycle Assessment – Environmental Impacts

Organised by TensiNet and the Working Group Sustainability & Comfort (coordinator Carol Monticelli - Politecnico di Milano / Marijke Mollaert VUB)

Programme

13.00 – 13:05 Opening and Welcoming - Chair: Marijke Mollaert (VUB and Tensinet)

13.05 – 13.20 What is the Life Cycle Assessment? And what does it mean in Membrane Architecture Field? -  Carol Monticelli (Polimi – Dept. DABC – Textiles Hub - LCTeams)

13.20 – 13.35 Environmental Product Declarations in Tensile Architecture: Available Datasets and Environmental Impact based on Global Warming Potential -  Zehra Eryuruk (VUB – Dept. Mechanics of Materials and Constructions)

13.35 – 13.55 Q&A - Katja Bernert

13.55 – 14.00 Closure of the meeting - Marijke Mollaert

Life Cycle Assessment (LCA) is a scientific methodology used to evaluate the environmental impacts of a product or system throughout its entire life cycle, from raw material extraction to end-of-life. In membrane architecture, LCA helps designers and engineers assess and reduce the environmental footprint of lightweight building solutions such as technical textiles and foils.

Compared to traditional construction materials, membrane and foil structures require significantly less material, thanks to their ability to work efficiently in tension. However, their fossil-fuel origin and their thermal, optical, and acoustic performance require careful environmental evaluation during the design phase. LCA makes it possible to identify both advantages and limitations of membrane materials, while tools such as Environmental Product Declarations (EPDs) support informed decision-making and promote more sustainable membrane architecture.

Join the TensiNet FREE WEBINAR “Membrane Architecture – Life Cycle Assessment – Environmental Impacts” on Friday, March 6, 2026, from 13:00 to 14:00 CET. The webinar will introduce LCA principles, their application to membrane structures, and present the currently available Environmental Product Declarations (EPDs) for membrane materials and systems. Please find the link to add your name on this list. Registration to participate in the webinar is a two-step process.

PFAS (per- and polyfluoroalkyl substances) are a diverse family of chemicals.

Not all PFAS are the same. Each should be treated differently. PTFE's unique combination of properties sets it apart from other materials and makes it vital to the sectors it serves, especially tensile architecture. Regulation against all PFAS could result in tensioned membrane structures becoming obsolete. 

Members of the Fluoropolymer Product Group (FPG) have provided the industry and its downstream users with robust safety information and best practice guidelines. The comprehensive guide covers essential materials such as PTFE, ETFE, FEP, PFA and PVDF, all of which are widely used in tensile architecture. The FPG and its members are dedicated to ensuring the safe use, sustainable manufacturing and responsible end-of-life solutions of fluoropolymers.

SAVE THE DATE - 05.02.2026

The TensiNet Working Group Sustainability and Comfort and its industrial members will organise a FREE WEBINAR on 5/2/2026 about the PFAS restriction process, fluoropolymers and PFAS, membrane materials and the next SEAC consultation.
