Sungate® 400 Glass

Excellent Insulating Performance. Exceptionally Clear.

Sungate^® 400 glass is a highly transparent, passive low-e glass designed specifically for use in heating-dominated climates.

Reduce Winter Heating Costs

Manufactured with a magnetron sputtered vacuum deposition (MSVD) “soft coat,” Sungate^® 400 glass helps buildings harvest energy from the sun and retain solar and furnace heat to reduce winter heating costs. Sungate^® 400 delivers a winter U-value that is 9 percent higher than passive low‑e glasses manufactured with a “hard” pyrolytic coating.

Sungate^® 400 glass performs best when specified as a third-surface coating on Starphire^® glass. In a one-inch insulating glass unit (IGU), this configuration generates a solar heat gain coefficient (SHGC) that is 13 percent better than that of conventional clear glass in a third-surface configuration. Sungate^® 400 glass also has been engineered to work with Solarban^® 70 glass (formerly Solarban^® 70XL glass) and Solarban^® 60 glasses to optimize performance in triple-pane IGUs.
