Engineered for Architecture That Endures.

One Collection. Distinct Technologies. Engineered for Lasting Performance.

Permanent tensile architecture demands materials capable of maintaining structural integrity, dimensional stability and architectural appearance under sustained loading and long-term environmental exposure.

TensiLux® PTFE is FPC's collection of high-performance PTFE-coated fiberglass membranes developed for demanding architectural applications, including stadium roofs, landmark tensile structures, permanent shading systems and architectural building envelopes.

Manufactured in Riyadh, Saudi Arabia, the collection combines engineered fiberglass reinforcement, controlled weaving, multi-layer PTFE coating and specialized surface finishing to provide a range of material solutions with different mechanical, optical and architectural characteristics.

From high-strength EC4 structural membranes to versatile EC6 architectural fabrics, TensiLux® enables architects, engineers and fabricators to select materials according to their specific structural, environmental and design requirements.

Key Performance Characteristics

Structural Integrity

Engineered fiberglass reinforcement for defined tensile and dimensional performance.

Environmental Resistance

PTFE-coated systems developed for demanding outdoor exposure conditions.

Fire Performance

Product-specific reaction-to-fire classifications supported by applicable test documentation.

Light & Optical Control

Different membrane constructions provide distinct light transmission and reflection characteristics.

Engineered Surface Protection

Multi-layer PTFE and selected FEP surface technologies for coating and surface performance.

Fabrication Compatibility

Material constructions designed for specialist membrane fabrication and welding methods.

Two Distinct PTFE Technologies. One Architectural Standard.

The TensiLux® PTFE Architectural Membrane Collection brings together two engineered fiberglass reinforcement systems, developed to address different structural and architectural requirements.

ArchiShield® — EC4 Structural PTFE Membranes: engineered for demanding permanent tensile structures where high mechanical strength, dimensional stability and long-term performance are essential.

ArchiFlex® — EC6 Architectural PTFE Membranes: developed to provide versatile membrane solutions combining structural performance, material efficiency and fabrication compatibility for permanent architectural applications.

Both collections are manufactured using FPC's integrated fiberglass weaving and PTFE coating capabilities in Riyadh, Saudi Arabia.
