A new Energy Star certified front door can dramatically reduce drafts and stabilize indoor temperature year-round. The difference is felt in week one.

Energy Features That Matter

Polyurethane Foam Core: This dense core provides superior insulation and energy efficiency compared to a hollow door. It traps heat inside during cold winters.
ComfortTech™ Warm Edge Glazing System: This system improves thermal performance at the glass edge. Fewer cold spots near sidelites and decorative panels mean a warmer hallway.
Q-Lon Weatherstripping: Energy-Efficient Q-Lon Weatherstripping runs along the top and sides, interlocking with the Q-Lon corner seal for a tight perimeter against wind.
DuraFuse Finishing System: The DuraFuse finish holds up better against elements like winter wind, summer humidity, and salt air.
Energy Star Partner of the Year: ProVia is the only door manufacturer to ever win this honor — and they’ve won it 9 times across program history.
Heat-Resistant Window Trim: High-Performance Heat-Resistant Window Trim is warranted not to warp, crack or pull away. Less maintenance, more comfort.

Best Energy-Efficient Door Picks

Top Recommendation: A ProVia Embarq fiberglass door with full Energy Star certification for the deepest savings.
Best for Budget: A ProVia Legacy Steel front door with foam core, weatherstripping, and ComfortTech Glazing.
Best for Glass-Loving Designs: A door with ComfortTech Glazing paired with decorative sidelites for daylight without the draft.
