SunGuard® High Performance

Neutral 78/65

Keep heat where you want it

SunGuard Neutral 78/65 coated glass is designed for cooler climate zones where passive heat gain is desired. This color-neutral solution lets natural light in while harnessing solar energy to help save on heating costs. Neutral 78/65 coated glass can be double- or triple-glazed and combined with other SunGuard high-performance low-E coatings, providing unparalleled choice.

Key features:

Neutral reflected and transmitted color: Create harmony in commercial designs
High passive solar heat gain: Meets energy codes in heating-dominated climates
Single product: For both annealed and heat treatment
Widely available: Guardian Select® fabricators can help you meet tight project deadlines
