Triple pane windows with argon or krypton gas and CFM rating of 0.1 keep heat in and cold out. These windows offer the lowest draft rating in the industry with superior insulation performance!
Furthermore, upgrading from single to triple pane windows saves over $500 annually on energy bills.
What New England Homeowners Need to Know:
Triple Pane Technology: When homebuyers upgrade from double to triple pane windows, energy efficiency performance improves by 40% or more. U-values of 0.20-0.30 give the biggest boost for insulation during the winter.
Gas Fill Insulation: Triple pane windows with argon or krypton gas create superior thermal barriers. A CFM rating of 0.1 represents the lowest draft rating available in today’s window industry.
Energy Savings Impact: Upgrading from single to triple pane windows saves over $500 per year on energy bills. It’s an energy efficient upgrade for both summer and winter months!
U-Value Performance: Triple pane windows achieve U-values of 0.20-0.30 compared to double pane U-values of 0.30-0.45. Lower numbers indicating better insulation and reduced heat transfer through glass surfaces.
ENERGY STAR Standards: Installing ENERGY STAR-certified windows lowers energy bills by up to 13% on heating and cooling costs.
Noise Reduction Benefit: Triple pane windows increase noise reduction to 40-50% compared to double pane windows at 30-35%.
Window Thermal Performance Comparison:
| Window Type | U-Value | CFM Rating | Annual Savings | Best For |
| Triple Pane with Gas | 0.20-0.30 | 0.1 | $500+ | Maximum insulation, extreme weather |
| Double Pane with Gas | 0.30-0.45 | 0.2-0.3 | $300-400 | Balanced performance, most climates |
| Single Pane | 0.90-1.10 | 1.0+ | Baseline | Replacement needed urgently |
*Lower U-values and CFM ratings indicate better thermal performance
Window Selection Recommendations:
Top Choice Overall: Triple pane windows with argon or krypton gas and 0.1 CFM rating delivering maximum insulation and $500+ annual energy savings
Best for Budget: Double pane ENERGY STAR-certified windows with argon fill providing solid thermal performance at approximately 50% of triple pane investment
Best for Coastal Areas: Triple pane windows with krypton gas offering superior performance in waterfront locations experiencing temperature extremes and high wind exposure
