A drafty door isn’t just uncomfortable — it’s costing you money every month. New England winters are serious, and your front door is one of the biggest weak spots in your home’s thermal envelope.

Key Insulation and Sealing Features to Look For
- Q-Lon Weatherstripping — Energy-efficient Q-Lon weatherstripping runs along the top and sides of ProVia doors, interlocking with a Q-Lon corner seal for airtight performance.
- Polyurethane Foam Core — The polyurethane foam core inside ProVia doors provides superior insulation, keeping heat in and cold air out throughout the season.
- ComfortTech Glazing — The ComfortTech Warm Edge Glazing System reduces thermal transfer through glass panels — a common source of heat loss in older doors.
- Energy Star Certification — ProVia is the only door manufacturer to win Energy Star Partner of the Year — and they’ve won it 9 times. That’s a standard no competitor matches.
- Door Jamb Integrity — The door frame and jamb must seal tightly on all sides. Gaps around the frame are just as harmful as gaps in the door itself.
- DuraFuse Finish — The DuraFuse Finishing System holds up against the freeze-thaw cycles that Brookline winters bring season after season.
A properly sealed door can cut heating and cooling costs by up to 13%. Our team does a full evaluation before any installation to identify all air infiltration points.
