Why Efficiency Matters in This Market

Heating Cost Savings: Certified doors save up to 13% annually on heating and cooling costs. For a 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.
