A flexible evacuated insulating panel comprises a first flexible external sheet (10) opposing a second flexible external sheet (20), each sheet comprises a plurality of corrugated gas impermeable layers (11) and (21) joined with a gas tight seal (18) to form an internal space that is evacuated of air (19). Spacers (12 and 22) press against a membrane (28) to resist the facewise compressive forces. The evacuated insulating panel is flexible, both in use and in application. As such, the panel may be manually applied to curved surfaces for any high-performance insulator application. The flexible evacuated insulating panel is mass-producible and useful in many different applications without custom design or manufacturing.
