Available at Windsor Plywood, Nichigo G-Tape is renowned for its unique combination of strength, ease of use, and clean removability. Unlike conventional tapes that use rubber or butyl adhesives, Nichigo G-Tape utilizes a patented solvent acrylic adhesive paired with a laminated polyethylene cloth backing. This construction provides superior adhesion, high dimensional stability, and excellent resistance to UV, water, and extreme temperatures ranging from -40°F to 200°F . The tapes are hand-tearable, repositionable, and remove cleanly without leaving residue, making them ideal for a variety of applications.

Frequently Asked Questions
What is Nichigo G-Tape and what does Windsor Plywood carry?
Windsor Plywood carries Nichigo G-Tape, a Japanese-manufactured self-adhesive flashing and sealing tape used in exterior construction for window and door rough opening sealing, air barrier seams, and waterproofing at envelope penetrations. G-Tape is a butyl rubber-based tape known for strong adhesion across a wide temperature range and compatibility with most building substrates.
What makes Nichigo G-Tape suitable for Canadian building envelope applications?
G-Tape maintains adhesion and flexibility in cold temperatures down to -10 degrees Celsius at application and performs across the temperature range encountered in Canadian conditions. Butyl rubber adhesive bonds to wood, OSB, concrete, metal, and polyethylene housewrap without primer on most substrates. Its UV resistance allows for a reasonable exposure period during construction before cladding is applied.
What applications is Nichigo G-Tape used for in construction?
G-Tape is used for flashing window and door rough openings, sealing seams in housewrap and air barriers, flashing penetrations in the building envelope including pipes and conduit, waterproofing transitions between different substrate materials, and sealing around deck ledger connections.
How is Nichigo G-Tape applied?
Clean the substrate surface to remove dust, frost, and loose material. Peel the release liner and press the tape firmly into place, working from one end to the other and rolling firmly with a J-roller or hand roller for full adhesion. For rough opening flashing, follow the sequence in the building code or manufacturer's installation guide to ensure proper lapping and drainage-plane continuity.
How does G-Tape compare to other flashing tapes available in Canada?
Nichigo G-Tape is recognized in professional building envelope work for its reliable adhesion across a wide temperature range and consistent performance in Canadian conditions. Windsor Plywood staff can advise on which tape is currently in stock and appropriate for your specific application.
