Kingspan GreenGuard® Seam Tape is self-adhering tape comprising a polyolefin film with an acrylic adhesive. Kingspan GreenGuard® Seam Tape adds an extra layer of air and moisture protection to structures. Kingspan GreenGuard® Seam Tape is recommended for flat surfaces. Kingspan GreenGuard® Custom Seam Tape is recommended for uneven surfaces, such as Kingspan GreenGuard® RainDrop®3D Building Wrap. Both tapes stick tight in all seasons, even when the temperature drops below freezing. Long-lasting UV stabilizers help them resist the deteriorating effects of the sun. The tapes can also be used to repair rips in damaged insulation and building wrap, eliminating waste and saving money.
