EnergyMaxx is the new Standard in High Performance Glass- Delivering energy-saving Comfort and uncompromised clarity:

EnergyMaxx multiple-layer low-emissivity glass, argon and krypton gas filling, and SST Warm-Edge Technology create a state-of-the-art energy-management system.

Preservation windows feature optional high performance glass packages that combine our sst warm edge spacer system, UV- filtering multiple-layer low-e glass with argon or krypton gas, in dual- or triple-pane insulating glass units. All are energy star qualified for every region of the united states and they help you reduce your heating and cooling costs, while making your home more comfortable.

The EnergyMaxx insulated glass package in Preservation Windows features solarban 60 multiple layer low emissivity 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 winter and the summer.

EnergyMaxx glass has patented coatings that reflect your home's heat back in the room during the winter and repel the sun's heat and damaging rays during the summer.

Air Infiltration- Preservation Windows are tested for air infiltration using the industry’s rigorous air infiltration resistance testing procedure. Test ASTM E 283

Water Resistance Preservation Windows are subjected to a driving water spray of five gallons per hour/per square foot (equals rainfall of eight inches per hour) at a simulated wind speed of over 60 mph. Test ASTM E 547

Structural Load Preservation Windows are subjected to interior (negative) and exterior (positive) structural load conditions simulating a wind speed of over 190 mph (the highest ranking on the Hurricane Damage Potential Scale is a Category 5, which is reserved for those hurricanes which exceed 155 mph wind speeds). Test ASTM E 330.

EnergyMaxx 10

EnergyMaxx 10 is our ultimate glass system and it is perfect for Minnesota's climate. EnergyMaxx delivers performance over 300% more efficient than ordinary low-e glass with an interior glass pane and two insulating chambers of krypton gas. The result is a triple-pane insulating glass unit that delivers ultra-high energy-efficiency. And, because all three panes are made of glass, the distortion and haze that can result in non-glass systems is eliminated.

Blocking of Damaging Rays

This chart shows the blocking power of the EnergyMaxx glasses against damaging rays.

EnergyMaxx7

Energymaxx 7 is over 125% more energy-efficient than ordinary low-e or mid-e glass systems because it combines two panes of multiple-layer vacuum-deposition low-e glass with an interior glass pane and two insulating chambers of argon gas. The result is a triple-pane insulating glass unit that is nearly four times more energy efficient than non-coated insulating glass. And, because all three panes are made of glass, the distortion and haze that can result in non-glass systems is eliminated.
