When planning a home renovation, energy efficiency isn’t always top of mind — especially when choosing finishes like cabinetry, flooring, or fixtures. But if your remodel includes replacing doors, you have a major opportunity to improve comfort, lower energy bills, and reduce your environmental footprint.
Modern door technology has come a long way in terms of performance and insulation. Whether you’re updating interior spaces or giving your home’s exterior a facelift, choosing energy-efficient doors during renovation can deliver lasting value.
How Doors Affect Energy Use
Doors are more than entry points — they’re part of your home’s thermal envelope. Older or poorly sealed doors can be a major source of heat loss in the winter and cool air loss in the summer. Drafts, gaps, and low-quality materials all contribute to:
- Higher heating and cooling costs
- Inconsistent indoor temperatures
- Cold spots near doorways
- Added strain on HVAC systems
By upgrading to newer, well-insulated doors, you can create a more airtight home that stays comfortable year-round.
Features to Look for in Energy-Efficient Doors
If energy savings are part of your renovation goals, keep an eye out for doors with:
- Solid cores or insulated materials (like polyurethane foam)
- Weatherstripping to block air leakage
- Low-emissivity (Low-E) glass in doors with windows
- Tight-fitting frames and thresholds
- Energy Star® certification
These features help maintain indoor temperature while reducing reliance on heating and cooling systems.
Best Times to Upgrade Your Doors During Renovation
Door replacement fits seamlessly into many types of remodeling projects, including:
- Kitchen remodels: match interior doors with cabinetry finishes
- Basement finishing: add energy-efficient exterior doors to walkouts
- Open-concept renovations: upgrade sliding or French doors to better-insulated options
- Siding or entryway upgrades: replace old front doors for improved curb appeal and performance
Coordinating door installation with your renovation timeline can prevent rework and reduce labor costs.
Additional Tips for Energy-Smart Renovations
- Add a storm door for an extra layer of insulation
- Use door sweeps to block drafts at the base
- Seal gaps with caulk or expanding foam
- Pair door upgrades with new windows for maximum efficiency gains
If you’re investing in a home renovation, don’t miss the chance to make your space more energy-efficient. Replacing outdated doors with modern, high-performance models is a small change that can lead to big savings — and greater year-round comfort.
A smarter home starts with smarter upgrades — and your doors are the perfect place to begin.
