Insulated Glass Packages
Preservation Windows offer optional high-performance glass packages that combine our SST Warm-Edge Spacer System and low-emissivity (Low-E) glass with argon or krypton gas in dual- or triple-pane insulating glass units. These state-of-the-art windows are ENERGY STAR-qualified and designed to help reduce your energy spending year-round.
The EnergyMaxx insulated glass technology in Preservation Windows features multiple layer Low-E glass, the latest advancement in glass coatings. Annealed flat glass is vacuum coated with multiple layers of silver and titanium that combine to create high-efficiency glass with unsurpassed properties of energy efficiency, UV reflection, clarity, damage reduction and visible light transmittance. The result is added comfort and energy efficiency in both the summer and winter.
