- Selective Transmission: Blocks unwanted heat while maintaining natural light
- Year-Round Benefits: Reduces cooling loads during Florida's extended warm season
Thermal Insulation Performance
- Multiple Glass Panes: Double or triple glazing creates insulating air spaces
- Gas Fills: Argon or krypton gas fills enhance insulation performance
- U-Factor Ratings: Superior impact windows achieve U-factors of 0.25-0.35
- Thermal Breaks: Frame materials prevent thermal bridging and heat transfer
Air Infiltration Control
- Superior Sealing: Multiple weatherstrip systems eliminate air leaks
- Structural Integrity: Robust frames maintain seal integrity over time
- Professional Installation: Precise installation ensures optimal sealing performance
- Draft Elimination: Prevents conditioned air loss and outside air infiltration
Quantifying Energy Savings
Impact windows provide measurable energy savings that compound over their 25-30 year lifespan:
Immediate Cooling Cost Reductions
| Home Size | Monthly Savings | Annual Savings | 20-Year Savings |
|---|---|---|---|
