The multi chambered virgin vinyl frame with steel reinforcement is the only one of its kind.  The pocket sill is unique to our windows for added security and stops all air infiltration.  The PPG’s solar ban 60 low- E glass and “warm edge” spacer system is surpassed by none. 

Between the panes of glass all windows feature argon gas, a colorless, nonflammable, odorless, non toxic and safe inert gas.  This gas is heavier than air, adding an insulating layer to reduce transmittance of heat and cold, while still letting the light through, in addition to exceptional noise reduction.  The frame is fusion welded and the lift rails are formed on the extrusion. 

The window has an interlocking meeting rail system with a cam shaft lock that tightens the window and helps seal the Mylar fin seal weather-stripping. Night locks are also added and tilt features are standard for easy cleaning.
