Energy Efficiency & Savings: The ROI Calculator

Window Film Energy Performance

Modern window films deliver measurable energy savings:

• Heat Rejection: 40-80% of solar heat blocked
• UV Blocking: 99% of harmful UV rays rejected
• Annual Energy Savings: $120-$400 per year (average home)
• ROI Timeline: 2-5 years for full payback
• Lifespan: 10-20+ years with minimal maintenance

10-Year ROI: Initial investment of $2,000 + $3,000 in energy savings = $1,000 net gain, plus extended HVAC lifespan.

Blinds Energy Performance

Blinds provide moderate insulation when properly used:

• Heat Reduction: 15-45% when fully closed
• UV Blocking: 60-90% when closed
• Annual Energy Savings: $50-$200 per year (requires daily adjustment)
• ROI Timeline: 5-15 years
• Lifespan: 5-10 years (mechanisms wear out)

10-Year ROI: Initial investment of $2,500 + $1,500 in energy savings + $800 replacement cost = -$1,800 net cost.

Curtains Energy Performance

Thermal curtains offer good insulation but limit functionality:

• Heat Reduction: 25-50% when closed (thermal-backed)
• UV Blocking: 70-99% when closed
• Annual Energy Savings: $75-$250 per year (if kept closed)
• ROI Timeline: 8-20 years
• Lifespan: 5-15 years (fabric degrades, styles change)

10-Year ROI: Initial investment of $3,500 + $1,800 in energy savings = -$1,700 net cost.
