Energy-Efficient Windows
Cut your energy bills and improve comfort with ENERGY STAR certified windows. Low-E glass, gas fills, and insulated frames engineered for the Tri-State climate.
Energy Efficiency
Stop Paying to Heat & Cool the Outdoors
If your windows are more than 15 years old, they're likely costing you hundreds of dollars per year in wasted energy. Old single-pane or failed double-pane windows let conditioned air escape and force your HVAC system to work overtime.
Modern energy-efficient windows use advanced glass coatings, gas fills, and insulated frame technology to create a thermal barrier between your home and the outside elements. The result: lower energy bills, more consistent indoor temperatures, and a smaller carbon footprint.
Cosello Construction installs ENERGY STAR certified windows from Andersen and other premium brands, specifically rated for the northern climate zone. We'll help you choose the right performance specs for your home's orientation, climate exposure, and budget.
What Makes a Window Energy-Efficient?
Low-E Glass Coatings
Microscopically thin metallic coatings reflect heat back to its source — keeping your home warm in winter and cool in summer without blocking natural light.
Argon & Krypton Gas Fills
Inert gas between panes provides superior insulation compared to air, reducing heat transfer and improving the window's overall U-factor.
Insulated Frames
Vinyl, fiberglass, and composite frames with thermal breaks prevent heat conduction through the frame itself — a common weak point in older windows.
Solar Heat Gain Control
Choose glass with the right Solar Heat Gain Coefficient (SHGC) for your home's orientation to balance warmth and light in every season.
ENERGY STAR Certified
We install windows that meet or exceed ENERGY STAR requirements for the northern climate zone, qualifying you for potential utility rebates.
Up to 30% Energy Savings
Homeowners who replace single-pane windows with ENERGY STAR products can save $126–$465 per year on energy bills, according to the DOE.
