When replacing windows, one of the biggest decisions is whether to invest in energy efficient windows or stick with standard replacements. The upfront cost difference can be significant, but so can the long-term savings. In this comprehensive comparison, we break down the real ROI of energy efficient windows versus standard windows for New Jersey homeowners.
Garden State Brickface has been helping NJ families choose the right windows for over 70 years. We offer both energy efficient and standard windows, and our experts help you determine the best value for your situation.
What Makes a Window Energy Efficient?
Low-E Glass Coatings
Microscopically thin metallic layers that reflect infrared heat while allowing visible light through. In winter, they reflect interior heat back inside. In summer, they reflect solar heat away. Standard windows typically lack these coatings.
Multiple Pane Glass with Gas Fill
Energy efficient windows feature double or triple panes with argon or krypton gas fill between them. These gases are denser than air and provide superior insulation. Standard double panes often have only dry air, offering significantly less thermal resistance.
Insulated Frames and Warm-Edge Spacers
Energy efficient frames use thermal breaks, foam insulation, and multi-chamber construction that prevent heat conduction. Warm-edge spacer systems use low-conductivity materials that reduce heat transfer at glass edges. Standard frames and spacers conduct more heat, creating cold spots and condensation.
Head-to-Head Comparison
Upfront Cost
Standard: $200 to $500 per window installed
Energy Efficient: $350 to $800 per window installed
Energy efficient windows cost roughly 30 to 60 percent more upfront. For a typical NJ home with 15 to 20 windows, the difference ranges from $2,000 to $6,000.
Annual Energy Savings
Standard: Minimal improvement over existing old windows
Energy Efficient: $200 to $500+ annual savings on heating and cooling
ENERGY STAR certified windows save $101 to $583 per year depending on climate zone. NJ’s climate means savings tend toward the higher end.
Return on Investment Timeline
Standard: 70 to 80 percent ROI at resale
Energy Efficient: 70 to 85 percent ROI at resale, plus ongoing energy savings
Energy efficient windows pay back their premium within 3 to 7 years. After payback, every dollar saved is pure profit. Over a 20 to 30 year lifespan, cumulative savings are substantial.
Comfort and Noise Reduction
Standard: Basic weather protection
Energy Efficient: Superior draft elimination, consistent temperatures, significant noise reduction
UV Protection
Standard: Little to no UV protection
Energy Efficient: Block up to 95 percent of UV rays, protecting furniture and flooring from fading
Condensation Resistance
Standard: Prone to interior condensation in cold weather
Energy Efficient: Significantly reduced condensation due to warmer interior glass surface
Real-World ROI Example for a New Jersey Home
Scenario: NJ homeowner replacing 18 windows
- Standard windows total: $7,200 (18 x $400)
- Energy efficient total: $10,800 (18 x $600)
- Additional investment: $3,600
- Annual energy savings: $450
- Payback period: 8 years
- Total savings over 25 years: $11,250
- Net benefit of choosing energy efficient: $7,650
This does not include tax credits, increased home value, or comfort and UV protection benefits.
