A Closer Look at Interstate’s Two Window Lines

5200 Series – High-Value, Entry-Level Option

The 5200 series is designed for homeowners who want quality and customization while staying within a budget. It offers features that most “entry-level” windows do not.

Key Features

• Exterior color options in 14 standard colors
• Ability to custom-match almost any exterior color
• Smooth tilt-in operation with dual latches for easy cleaning
• Strong weatherstripping to keep air infiltration low
• FlexScreens available in full or half versions
• Built-in exterior trim that resembles a small brickmold
• Pocket design that allows siding to tuck into the frame for a clean finish

Energy Efficiency Notes

• Offered only as dual-pane, therefore will not meet the newest Energy Star 7.0 requirements
• Still performs well with available coatings, achieving U-values around 0.24 to 0.28

Best For: Full-home window replacements, investment properties, or budget-conscious projects that still need quality construction and customization.

6800 Series – Upgraded Design and Efficiency

The 6800 series adds stronger energy performance, more custom finishes and a more refined appearance.

Key Features

• Smoother, rounded sash profiles for a more finished look
• RoboLock system, allowing the window to tilt in using the two lock mechanisms
• Dual-pane or triple-pane options
• Up to six different glass packages, including the Fuel Saver triple-pane option with U-values as low as 0.16
• Interior laminate finishes in Light Oak, Dark Oak and Cherry
• Multiple hardware color options
• Exterior colors match those in the 5200 line
  

Best For: Homeowners who want better energy performance, more aesthetic options or a more premium vinyl upgrade without going to composite or fiberglass.
