Triple pane, ENERGY STAR certified windows are the most effective option for keeping heat in and cold out in New England.
Triple pane, ENERGY STAR certified windows are the most effective option for keeping heat in and cold out in New England.
If you’re dealing with drafty windows in winter, the problem usually isn’t the glass alone — it’s air infiltration around the frame and between panes. The right window cuts that infiltration dramatically. Local window replacement companies that specialize in cold climates know which specs matter most for homes in this region.
What Essex County Homeowners Should Look for in Energy-Efficient Windows
- Triple pane performance: Triple pane windows achieve a U-value of 0.20–0.30, compared to 0.30–0.45 for double pane. That lower number means significantly less heat escaping through the glass in winter.
- Draft rating matters: Coastal’s triple pane windows carry a 0.1 CFM draft rating — one of the tightest air infiltration ratings available. That spec directly addresses drafty windows in winter and reduces heating costs year-round.
- ENERGY STAR certified: ENERGY STAR certified windows are designed to meet strict thermal performance thresholds for cold climates. Thermal performance is a priority for 87% of window and door professionals surveyed nationally.
- Real energy savings: Upgrading from single to triple pane windows can save over $500 per year on energy bills. For homes north of Boston with older windows, that savings adds up quickly over the life of the product.
- Noise reduction bonus: Triple pane windows reduce outside noise by approximately 40–50%, compared to 30–35% for double pane. That’s an added benefit for North Shore homeowners near busy roads or coastal wind exposure.
- Strong ROI: Window replacement delivers a 76% return on investment nationally. Durability and longevity is rated important or very important by 100% of window and door professionals — the top priority in the industry.
