SIGA Membranes

SIGA membranes are engineered to support airtight, durable, and moisture-safe building envelopes when used as part of a complete system. These high-performance membranes are designed to control air leakage while remaining compatible with vapor-open assemblies, helping buildings manage moisture safely over time.

Commonly used in high-performance and Passive House–informed construction, SIGA membranes are specified for walls, roofs, and transitions where long-term airtightness and reliability are critical. Their performance depends not only on material properties, but on correct application, compatibility with tapes and substrates, and thoughtful detailing.

This collection includes interior and exterior SIGA membranes selected for specific assembly conditions. Small Planet Supply helps builders and designers confirm which membrane is appropriate for their climate, structure, and overall envelope strategy—so airtightness is intentional, not improvised.
