Glass Types and Energy Efficiency
The type of glass and its features affect both cost and energy efficiency:
- Single-Pane vs. Double-Pane windows
- Low-E Coatings for reduced energy loss
- Impact-Resistant Glass for severe weather areas
- Argon gas filling (10-15% cost increase)
According to ENERGY STAR®, replacing single-pane windows with energy-efficient models can save 583 per year on energy bills.
Labor and Installation Costs
Installation typically accounts for 30-50% of the total project cost. Factors affecting labor include:
Location-Specific Variables
