What is a Double Door? (The Configuration)

A double door (also called a double-leaf door) is a doorway opening fitted with two separate door panels. Each side is called a leaf.

Key concept: It’s a configuration, not a style. Both leaves may open (active/active), or one may stay fixed (active/inactive).

Double Door Characteristics:

Two doors meet in the middle.
Can be solid, paneled, or glass.
Can be made from wood, steel, fiberglass, or aluminum.
Used in front entries, interiors, or commercial spaces.

Examples:

Panel double entry doors made of solid oak.
Flush double doors in modern condos or offices.
French doors, which are glass-paneled double doors.

What is a French Door? (The Style)

Answer first: A French door is a style of double door built primarily from glass panes framed in wood, steel, or fiberglass.

Key characteristics:

Typically contains multiple glass panes, called lites.
Swings open from the center (inward or outward).
Allows maximum natural light and an open visual connection between spaces.
Common for patios, balconies, or interior room dividers.

Typical use cases:

Connecting living room to a patio or garden.
Creating transparency between a home office and hallway.
Letting natural light flow between rooms.

French Door vs. Double Door: A Head-to-Head Comparison

Answer first: Here’s a clear side-by-side comparison between a French door (glass) and a solid/panel double door (wood, steel, or composite).

Feature	French Doors	Solid / Panel Double Doors
Primary Feature	Glass panes	Solid panels (wood, steel, fiberglass)
Natural Light	Excellent	Minimal (unless sidelights)
Privacy	Low (add blinds/curtains)	Excellent
Security	Good — tempered or laminated glass	Excellent (solid cores resist forced entry)
Best For…	Patios, home offices, interior room dividers	Front entrances, bedrooms, closets
Average Cost (Installed)	$2,000 – $8,000+	$1,500 – $7,000+
Energy Efficiency	Moderate (depends on Low‑E double glazing)	High (solid cores insulate better)

Pros and Cons of French Doors

Answer first: French doors are beloved for light, elegance, and connecting indoors to outdoors, but they trade privacy and insulation for beauty.

✅ Pros:

Natural Light: Brightens interiors, making rooms feel larger.
Elegant Aesthetics: Timeless and sophisticated; fits traditional and modern homes alike.
Indoor–Outdoor Flow: Creates seamless transitions to decks, patios, or gardens.
Visual Connection: Ideal for interior use—separate spaces without isolation.

❌ Cons:

Privacy Limitations: Transparent glass may require curtains or frosted finishes.
Security Considerations: Though tempered glass is strong, it’s still breakable.
Insulation: Glass transfers heat/cold more than solid doors (upgrade to double-glazed Low‑E).
Swing Space: Inward/outward swing requires clearance.

Consider adding storm doors or tinted glass for improvement—learn more in our Patio Doors Buying Guide.

Pros and Cons of Solid Double Doors

Answer first: Solid double doors are built for protection, privacy, and durability—but can visually feel heavy compared to French doors.

✅ Pros:

Maximum Privacy: Perfect for entryways, bedrooms, or utility spaces.
Superior Security: Solid cores deter intrusion; best for front entries.
High Energy Efficiency: Excellent insulation; reduces drafts.
Style Flexibility: Available in wood, fiberglass, steel, or aluminum.
Durability: Withstands dents, cracks, and scratches better than glass.

❌ Cons:

Blocks Light: No glass means darker interiors.
Heavier Aesthetic: Can feel imposing in smaller spaces.
No Visual Connection: Fully divides rooms—less visual openness.

Cost Comparison: French Doors vs. Double Doors

Answer first: Costs vary widely depending on materials, installation type, and whether it’s for exterior or interior use.

Material Impact on Cost (Lowest → Highest):

Hollow Core (interior only): Most affordable; under $500.
Vinyl: Great for budget exterior patio doors.
Fiberglass: Balance of cost, efficiency, durability.
Steel: Secure, contemporary look; mid-range pricing.
Wood (Pine/Oak): Warm aesthetic, requires maintenance.
Custom Aluminum / Clad Wood: Premium luxury range.

Installation Factors:

Pre-hung vs. Slab: Pre-hung easier, cheaper by $200–$400.
Retrofit vs. New Opening: Adding a new double doorway adds $500–$1,000 for framing.

Door Type	Installed Cost Range (USD)
Interior Double Door	\500 – \2,500
Exterior Solid Double Door	$1,500 – $7,000+
Exterior French Door	$2,000 – $8,000+
