Engineered for construction companies seeking innovation in their projects, CNG’s roofing underlayment films are the next step in protecting roofs against the environment. From air and moisture barriers to breathability, roofing underlayment films enhance construction projects by protecting against water and ice damage, sealing around fasteners to prevent leaks, and ensuring superior laps that minimize water infiltration. Resilient to tears and punctures, CNG films withstand extreme conditions like high winds, heavy rain, and freezing temperatures. Treated surfaces optimize printing and adhesive coating, and they laminate easily to woven and non-woven substrates. CNG roofing underlayment films are reliable and versatile, providing robust products through to the contractor, the jobsite and the eventual roof sheltering the resident.
