Core Takeaways: What to Know Before Buying an Entrance Double Door
An entrance double door is a paired door system installed at a building’s main entry, designed to provide a wider opening for pedestrian flow, large items, or aesthetic impact. Before you evaluate specific products, understand these fundamentals:
- Standard total widths for entrance double doors range from 60 to 72 inches (152–183 cm), with each leaf typically 30 to 36 inches wide. Commercial applications often require wider configurations up to 96 inches.
- Material choice drives performance. Aluminum offers the best strength-to-weight ratio for large panels; wood provides classic aesthetics but demands maintenance; steel maximizes security; fiberglass balances insulation and durability.
- Security depends on hardware, not just material. Multi-point locking systems and reinforced astragals (the vertical strip where doors meet) matter more than the door skin itself.
- Thermal performance is non-negotiable for exterior applications. Look for thermal-break frames and low-E glazing to meet modern energy codes.
- Budget realistically. Double doors cost roughly 1.5 to 2 times a comparable single door when accounting for framing, hardware, and installation.
The sections below walk through each decision point in detail.
Types of Double Entrance Doors: Materials and Configurations
Material Comparison
Aluminum dominates commercial entrance applications. Extruded aluminum frames with thermal breaks (polyamide strips separating interior and exterior metal) deliver excellent structural rigidity for wide spans. Powder-coated finishes resist corrosion in coastal environments. The main trade-off: aluminum conducts heat more readily than other materials, so thermal-break construction is essential for energy performance.
Wood remains the preferred choice for high-end residential and hospitality projects. Solid hardwood species like oak, mahogany, or walnut offer timeless aesthetics and natural insulation. The drawbacks are real: wood expands and contracts with humidity changes, requires periodic refinishing, and can warp in extreme climates unless properly engineered with laminated construction.
Steel provides the highest security and impact resistance. Galvanized steel doors with polyurethane foam cores resist forced entry and withstand severe weather. The trade-off: steel dents on impact, conducts heat and cold rapidly without proper thermal breaks, and limits design flexibility compared to aluminum or wood.
Fiberglass has gained traction as a middle-ground option. A fiberglass skin over an insulated core mimics wood grain appearance while resisting moisture, insects, and temperature-driven warping. It accepts paint well and requires minimal maintenance. However, fiberglass doors cost more than steel and offer less design flexibility than aluminum for custom configurations.
Configuration Options
Hinged double doors are the conventional choice. Two side-hinged leaves open outward or inward, with one leaf (the active door) used for daily passage while the inactive leaf remains secured. This configuration works best where floor space allows full door swing.
Sliding double doors operate on overhead tracks or floor rollers. They save interior space since no swing radius is required. The trade-off: sliding systems typically have more moving parts, require precise track alignment, and may not achieve the same air-sealing performance as hinged doors.
Pivot doors rotate on a vertical axis set back from the door edge, allowing the door to swing both inward and outward. This creates a dramatic architectural statement and accommodates very wide openings. Pivot hardware costs significantly more than standard hinges and requires precise engineering for heavy door leaves.
Multi-fold doors (bi-fold or accordion configurations) suit openings that need to open fully to the exterior, common for restaurant terraces or indoor-outdoor living spaces. They offer maximum openness but provide less weather resistance when closed compared to hinged or sliding systems.
Double Door vs. Single Door: Which Is Right for Your Project?
The decision between a single and double entrance door hinges on three factors: traffic flow, object movement, and architectural proportion.
Traffic flow: A single 36-inch door accommodates one person at a time comfortably. A double door with two 36-inch leaves provides a 72-inch opening that handles two-way pedestrian traffic efficiently. For commercial buildings with moderate to high foot traffic, the double door reduces congestion and improves accessibility compliance.
Object movement: If your project involves moving furniture, equipment, or large goods through the entrance, the wider clear opening of a double door eliminates the need for special handling. Hospitals, schools, and hospitality venues frequently specify double doors for this reason.
Architectural proportion: Double doors visually anchor a facade. On buildings with wide frontages or high ceilings, a single door can appear undersized. The double door creates a more imposing, welcoming entrance that suits institutional, retail, and luxury residential projects.
The cost difference matters. A double door requires wider rough openings, additional framing, more hardware, and potentially structural headers to support the wider span. Expect to pay 50–100% more than a comparable single door installation.
Key Features to Compare: Security, Insulation, and Durability
Security Hardware
The astragal—the vertical component where two door leaves meet—is the critical security element. Three types exist:
- Fixed astragals permanently connect both leaves, requiring both to open together. They offer the strongest security but limit daily-use flexibility.
- Removable astragals allow the inactive leaf to be secured independently while permitting full-width opening when needed. This is the most common configuration for commercial applications.
- Overlapping astragals feature one leaf with an extended edge that covers the gap when closed. They provide good weather sealing but can complicate hardware installation.
Multi-point locking systems engage bolts at multiple positions along the door edge—typically at the top, bottom, and center. This distributes force across the frame, resisting forced entry and reducing warping pressure on tall doors. For double doors, the active leaf should have a multi-point lock, while the inactive leaf requires top and bottom bolts or shoot bolts that engage the frame.
Thermal and Weather Performance
Exterior double doors face demanding conditions. Three performance metrics matter:
Air-tightness measures how much air passes through the door assembly under pressure. Look for gasketing at all meeting edges, including the astragal, threshold, and frame perimeter. Poor air-tightness leads to drafts, energy loss, and dust infiltration.
Water-tightness evaluates resistance to rain penetration. Doors with proper weatherstripping and drainage systems in the frame channel water away from the interior. For coastal or high-rainfall regions, specify doors tested to higher water-tightness classifications.
Wind resistance matters for tall buildings and hurricane-prone areas. The door assembly—including frame anchoring, glazing, and hardware—must withstand design wind loads. Impact-rated glazing may be required in certain jurisdictions.
For thermal insulation, the frame material and glazing specification determine performance. Thermal-break aluminum frames with low-E insulated glass units achieve U-factors comparable to wood or fiberglass while maintaining structural advantages.
Durability Factors
Consider the door’s exposure environment. Coastal installations require corrosion-resistant hardware and finishes. High-traffic commercial entrances need impact-resistant surfaces that tolerate frequent use. The finish system—anodizing, powder coating, or paint—significantly affects lifespan. Powder-coated aluminum typically outperforms painted steel in outdoor applications.

How to Choose a Reliable Manufacturer
The door’s performance ultimately depends on manufacturing quality and proper specification. When evaluating suppliers, focus on these criteria:
Factory-direct capability. Manufacturers that control their own production can offer better pricing and more consistent quality than those who source from multiple subcontractors. Direct factory supply also means clearer communication on custom specifications.
Testing and quality control. Reputable manufacturers conduct pre-shipment inspections covering air-tightness, water-tightness, and wind resistance. Ask for test reports and understand what standards they reference. Regional requirements vary—a door certified for a mild climate may not meet hurricane or extreme cold standards.
Customization capability. Your project may require non-standard sizes, specific glass specifications, or particular hardware integration. Ensure the manufacturer can accommodate custom dimensions without compromising structural integrity. For large openings, frame reinforcement and mullion design become critical.
Export and logistics experience. If sourcing internationally, the manufacturer should handle documentation, packing, and shipping arrangements. Understanding FCL and LCL shipping options helps manage costs for different order volumes.
Code compliance support. Building codes for egress, fire safety, and accessibility vary by jurisdiction. A manufacturer with export experience can adjust profile structures and fittings to match local requirements.

Frequently Asked Questions About Double Door Entrances
What are the standard sizes for entrance double doors?
Residential double doors typically measure 60, 64, or 72 inches total width, with each leaf 30–36 inches wide. Standard heights are 80 or 96 inches. Commercial applications often use 72–96 inch total widths with 84 or 96 inch heights. The rough opening must be approximately 1–1.5 inches wider and 1 inch taller than the door unit to accommodate framing and shimming.
Which material is best for an entrance double door in terms of durability and insulation?
For balanced performance, thermal-break aluminum offers the best combination of structural durability and thermal efficiency. Wood provides superior natural insulation but requires ongoing maintenance. Steel maximizes security but performs poorly thermally without additional insulation. Fiberglass offers low maintenance with good insulation but limited design flexibility.
How do double door entrances compare in cost to single doors?
A double door installation typically costs 1.5 to 2 times more than a comparable single door. This accounts for the additional door leaf, wider framing, more hardware, and increased installation labor. Custom sizes, premium materials, and specialized glazing increase costs further.
What security features should I look for in a double door front entrance?
Prioritize a multi-point locking system on the active leaf, shoot bolts on the inactive leaf, and a reinforced astragal. The frame must be anchored securely to the building structure. For high-security applications, specify steel reinforcement in the lock area and impact-resistant glazing.
Can entrance double doors be customized to fit non-standard openings?
Yes, reputable manufacturers accommodate custom sizes. However, very wide or tall doors require additional engineering for structural rigidity. If your opening exceeds 96 inches, consider adding a fixed sidelite or mullion to maintain door stability. Always verify that custom doors meet local building codes for egress and wind load.
What are the key differences between hinged, sliding, and pivot double doors?
Hinged doors offer the best sealing and security but require swing clearance. Sliding doors save space but have more moving parts and lower weather performance. Pivot doors create dramatic architecture and allow wide openings but cost significantly more and require precise engineering. Choose based on space constraints, performance requirements, and budget.
How do I ensure the double door meets local building codes and energy efficiency standards?
Consult local building officials early in the design process. Key considerations include egress width requirements, fire ratings for certain occupancies, and energy code requirements for U-factor and air leakage. Work with a manufacturer who can adjust profiles and glazing to meet regional standards, and request test documentation for the specific door configuration you specify.
