Why Efficiency Matters in This Market
- Heating Cost Savings — Certified doors save up to 13% annually on heating and cooling costs. For a Brookline home with high energy use, that compounds fast.
- Insulating Efficiency Demand — According to FIXR survey data, 60% of homeowners rate insulating efficiency (U-Value/R-Value) as the top eco-friendly feature they want.
- ProVia’s Unique Achievement — ProVia is the only door manufacturer ever to win Energy Star Partner of the Year — a distinction they’ve earned 9 times.
- ComfortTech Glazing — The ComfortTech Warm Edge Glazing System reduces heat transfer at the glass edge, which is where most thermal loss occurs in glass panels.
- Foam Core Construction — A polyurethane foam core dramatically improves the door’s R-value compared to hollow-core alternatives.
- Long-Term Value — Steel doors carry a 216% ROI. Pair that with energy savings, and the financial case for upgrading becomes hard to argue against.
