ClimaGuard Neutral 70
Durability and efficiency for doors and specialty applications

ClimaGuard® Neutral 70 represents a new standard in durable high performance low-E glass. Designed for use in light commercial and residential applications, Neutral 70 provides the optical clarity and energy performance traditionally associated with sputter coatings. It also has handling and fabrication characteristics comparable in most respects to pyrolytic coatings. Neutral 70 is the perfect solution for doors and wear-and-tear applications, such as between-the-glass blinds.
