Blue Dolphin breathable seam tape is a specialized construction product developed for joining and repairing breathable underlays and other polypropylene-based non-woven materials. The key feature of this product is its high vapor permeability, which ensures that any moisture trapped in the structure can evaporate through the taped seam, preventing the risk of moisture damage.
The tape features a durable black polypropylene non-woven backing that blends visually with most underlay materials. The high-quality acrylic adhesive provides excellent initial tack and long-term durability, withstanding rain, moisture, and UV radiation, making it a reliable choice for both new construction and renovation projects.
