energyEnergy Advantage Low-E glass from Pilkington is a high performance, energy efficient window glass made with an invisible coating that blocks heat flow. Energy Advantage Low-E glass keeps heat inside in the window, reduces condensation , filters damaging UV rays, and keeps heat out in the summer.

You can also have Pilkington’s Activ™ self-cleaning glass as an option with any of our windows.

Thermal Edge™ warm edge spacer is a standard feature in every PROWAY Window. Thermal Edge™ reduces the occurrence of condensation by increasing the glass edge temperature in winter. Thermal Edge™ enhances the performance of Low-E and Argon gas filled units and because they are made of steel, they increase the structural integrity of our windows over foam or aluminum type spacers.
