Replacement Windows & Doors

Energy Star® is a government-backed certification that identifies windows and doors that meet strict energy efficiency guidelines.

Energy Star rated products:

• Reduce heat transfer
• Improve insulation performance
• Lower energy bills
• Increase indoor comfort
• Meet climate-specific standards

For New England, products must meet performance levels designed for cold winters and seasonal temperature swings.

Older windows often:

• Lack Low-E coatings
• Have air leaks
• Use outdated spacer systems
• Lose insulating gas over time
• Allow drafts and condensation

Modern energy-efficient windows use:

• Low-E glass coatings
• Argon or Krypton gas insulation
• Warm-edge spacer systems
• Improved frame insulation
• Multi-point weather sealing

The result: better comfort, lower energy costs, and improved durability.

Energy Star evaluates windows using performance metrics such as:

• U-Factor (insulation value)
• Solar Heat Gain Coefficient (SHGC)
• Air leakage
• Visible transmittance

Products must meet region-specific standards to qualify.

We help you understand what those numbers actually mean — and which ratings are best for your home.

• Low-E (Low Emissivity) glass reflects heat while allowing natural light inside.
• Argon gas fills the space between panes to increase insulation.
• Krypton gas offers even higher insulation performance in narrower spaces.

Combined with a warm-edge spacer system, these features significantly reduce heat loss in winter and heat gain in summer.

Energy-efficient window replacement can:

• Reduce heating and cooling costs
• Improve resale value
• Eliminate draft discomfort
• Increase curb appeal
• Reduce outside noise
• Remove the need for storm windows

Quality window upgrades consistently rank among high-return home improvements.
