SIGA Tapes & SIPS
SIGA tapes and membranes offer air and weather barrier solutions for SIP construction.
Structural Insulated Panels or “SIPs” are a high-performance building system that serves as the structure and insulation of a building. These building envelopes are extremely robust, energy efficient and cost effective. Typically, SIPs consist of insulating foam core inside two structural OSB facings. SIP building systems are airtight and extremely well-insulated, but their weakest points are panel joints- if the joints are not properly sealed.
SIGA Wigluv 60 tape is designed to seal SIP exterior OSB sheathing seams, as well as rough openings for windows, doors and penetrations. All exterior panel seams (including roof and side walls) can be sealed with Wigluv. With extraordinary adhesive strength at high and low temperatures, Wigluv is rain-proof and impervious to water, with a slight perm rating to allow panels to dry properly. Wigluv’s material technology prevents condensation buildup on the tape, making it a smart choice for sealing panel joints on the exterior. In addition to effective sealing, Wigluv forms extremely well to OSB, and application is simple and clean.
Rissan 60 and Rissan 100 tapes are used to seal the interior SIP joints. Rissan tape is vapor closed and contains no VOC’s. Like Wigluv, it bonds extremely well to OSB. Taping SIP joints with Rissan ensures a tight seal on the building interior, and helps prevent moisture from penetrating the weakest areas of the panels. Rissan also applies easily around interior pipe penetrations, and guarantees a uniform air seal for the structure’s weak points. Upright Frameworks, a weatherization and general contracting/ SIP construction company in Maine, attests to the quality of SIGA Tapes in SIP applications: “We prefer working with SIPs for our new construction projects, and so we’re pretty confident that we know how to create tight structures. But when the specs require a specific ACH target, we don’t leave anything to chance. We use SIGA Tape on all our panel seams.”
When failure is not an option, SIGA Tapes provide exceptional, high-performance air sealing in a SIP building system.
