Double Front Exterior Doors: B2B Procurement Guide & Pricing

13 min read

A contractor in Ohio once ordered a 72-inch double door unit. It arrived on schedule, but the pre-hung frame was warped 3/8 of an inch across the diagonal. The installer spent four hours shimming it. The client noticed the gap. The contractor ate the labor cost.

That is the reality of sourcing double front exterior doors without a proper specification sheet. The product looks simple — two panels, one frame, some hardware. But tolerances, material behavior, and code compliance make it a technical purchase. This guide covers what B2B buyers need before placing an order: material science, cost drivers, supplier qualification, and factory processes.

1. Understanding Double Front Exterior Doors: Types and Applications

A double front exterior door system consists of two independently operating door panels within a single frame, typically 60 to 72 inches wide. Both leafs can be active, or one can be fixed with an astragal covering the seam. The configuration depends on egress requirements, aesthetic goals, and usage.

Terminology Across the Industry

Different markets use different terms. In the US, “double entry door” and “double front door” are common. In Europe, suppliers often list them as “double action doors” or “two-leaf doors.” When both panels have full-lite glass, they are frequently called “double French doors,” regardless of location. For procurement, what matters is the specification sheet, not the marketing name.

There is also a critical distinction between a prehung double door unit and slab-only double doors. A prehung unit arrives with the frame, hinges, and sometimes trim assembled, squared at the factory. Slab-only doors require the installer to build the frame on-site, introducing more variables and potential for error.

French Doors vs. Double Entry Doors

French doors are a subset of double doors. The defining feature is the glass — French doors have full-lite panels with no center mullion, and both leafs are typically operable. Double entry doors can be solid, half-lite, or decorative-lite, often with one fixed leaf to reduce hardware complexity and improve security.

Feature	French Doors	Double Entry Doors
Glass coverage	Full-lite (90%+ of panel)	Varies — solid to decorative lite
Operability	Both leafs typically active	One leaf often fixed
Locking	Multi-point on both leafs	Multi-point on active leaf, bolts on fixed
Typical use	Patios, balconies, light-filled entries	Main entrances, formal facades
Security complexity	Higher — both leafs need locking	Moderate — one leaf can be simplified

Pros and Cons for Buyers

Double front doors suit projects where curb appeal and access width are priorities. They allow furniture and appliances to move in without a crane and create a symmetrical facade favored by architects. Downsides include higher cost than a single door with sidelites, more complex weather sealing, and heavier-duty hardware needs.

For a B2B buyer, the decision comes down to whether the end-client values the aesthetic enough to pay for extra engineering. It is not a decision to make lightly, especially in climates with extreme temperature swings or high wind loads.

2. Double Front Exterior Door Materials: Technical Comparison

Material selection drives performance, cost, and lead time. There is no universally “best” material — only the right fit for a given project’s climate, security needs, and budget.

Solid Wood Double Front Doors

Wood remains the premium choice for high-end residential and hospitality projects. Mahogany, oak, walnut, and teak are common species, with mahogany standard for carved and arched designs. Engineered wood composites offer better dimensional stability but are harder to carve.

Technical considerations:

• Moisture content should be 8–12% at finishing. Anything higher risks warping.
• Stile-and-rail construction with mortise-and-tenon joints is the industry standard.
• Veneer thickness should be at least 4/4 (one inch) for stain-grade finishes.

Wood’s drawback is maintenance. It requires periodic refinishing, and in humid climates, it can swell. For coastal projects, fiberglass or aluminum is often safer.

Fiberglass Double Front Doors

Fiberglass doors dominate the mid-to-high-end residential market. They offer the look of wood without maintenance, and they do not warp, crack, or rot. The surface can be factory-primed or finished with a wood-grain texture.

Popular configurations include 8’0″ tall 6-lite clear low-e fiberglass prehung double door units and vertical 1-lite designs with metal slats. The low-e coating reduces heat transfer, and the fiberglass skin provides an R-value around 5–7.

Aluminum and Thermal-Break Double Entry Doors

For modern architecture, aluminum is the material of choice. It offers slim sightlines that maximize glass area, high structural performance, and corrosion resistance for coastal environments. The key technology is the thermal break — polyamide strips that separate interior and exterior profiles to reduce heat transfer.

Aluminum doors meet AAMA standards for air, water, and structural performance. Powder coating allows any RAL color, and anodizing provides a metallic finish. Wood-grain foil finishes are available.

The trade-off is cost. Thermal-break aluminum double doors are typically the most expensive option per square foot, especially with custom sizes and finishes.

Steel Double Front Doors

Steel is the budget and security option. It is impact-resistant, difficult to force open, and inexpensive. Drawbacks are thermal performance (unless the core is insulated) and a tendency to dent. Design flexibility is limited — steel doors are typically flat-panel.

For commercial applications, security-focused residential, or utility buildings, steel is practical. For high-end residential facades, it looks out of place.

Material Comparison Table

Material	R-Value	Maintenance	Cost Range (B2B, per unit)	Typical Lead Time
Solid Wood	2–4	High (refinish every 2–3 years)	$2,000 – $6,000+	8–12 weeks
Fiberglass	5–7	Low (wipe clean)	$1,200 – $3,500	4–8 weeks
Aluminum (thermal-break)	3–5	Low (powder coat lasts 20+ years)	$2,500 – $5,000+	6–10 weeks
Steel	3–5 (insulated core)	Medium (scratch-prone)	$800 – $2,000	3–6 weeks

3. Key Specifications When Sourcing Double Front Exterior Doors

A complete specification sheet prevents misunderstandings. Buyers who skip this step often receive doors that do not fit the rough opening or fail local code.

Sizes and Configurations

Standard widths are 60 inches (5/0), 64 inches (5/4), and 72 inches (6/0). Heights typically run 80 inches (6/8) or 84 inches (7/0). For grand entrances, 96-inch (8/0) and 97-inch doors are available from most manufacturers.

Inswing vs. outswing is critical. Inswing doors are more common in residential settings because they do not expose hinges to weather. Outswing doors are required in some commercial applications and preferred in hurricane-prone areas because wind pressure pushes the door against the frame. Outswing doors need weatherstripping on the exterior face and hinge-side rain protection.

Glass and Glazing Options

Double-pane glass with low-e coating and argon fill is the minimum for energy-efficient projects. Triple-pane is available for extreme climates. Tempered or laminated glass is required for safety in most jurisdictions; laminated glass provides better security.

Decorative lites — grids, muntins, obscure glass, flemish patterns — add cost but also character. For energy performance, reference the U-factor and Solar Heat Gain Coefficient (SHGC) ratings per climate zone. ENERGY STAR provides minimum performance levels by region.

Hardware and Security Systems

Double doors require more hardware than single doors. A multi-point locking system (3-point or 5-point) secures the active leaf at multiple points. The passive leaf is secured with floor bolts or shoot bolts, along with an astragal covering the seam.

Hinges must be load-rated for panel weight. A solid wood panel can weigh 150–200 pounds, requiring ball-bearing or continuous hinges. Standard residential hinges will fail within months.

Building Codes and Compliance

The International Building Code (IBC) requires a minimum clear opening of 32 inches for egress in most occupancy types. For a double door, one leaf must open to at least 32 inches clear. Accessibility standards (ADA) require a 32-inch minimum for public buildings.

Hurricane-prone regions (e.g., Miami-Dade County, Florida) require doors to pass impact tests with missile and cyclic pressure tests. Energy codes (IECC) set maximum U-factors and minimum SHGC ratings by climate zone. A supplier must provide test reports and compliance documentation.

4. Cost Factors: How Much Do Double Front Exterior Doors Cost?

Pricing varies by material, size, glass, hardware, and finish. B2B buyers should expect wholesale prices 20–40% below retail when sourcing factory-direct.

Price Range by Material and Configuration

• Fiberglass double door units: $1,200–$3,500 per unit
• Solid wood double doors: $2,000–$6,000+ per unit
• Aluminum thermal-break double doors: $2,500–$5,000+ per unit
• Steel double doors: $800–$2,000 per unit

These are unit costs for the door, frame, and pre-hung hardware. Installation is not included.

What Drives the Price Up?

Custom sizing is the biggest cost driver. A non-standard width or height requires new frame setup and glass cuts. Arch tops, transoms, and sidelites add labor and material. Glass upgrades — impact-rated, low-e coatings, decorative patterns — increase cost significantly. Hardware grade matters; a multi-point locking system with a premium handleset can add $300–$800 per door.

How B2B Buyers Can Control Costs

Standardize sizes across projects. A 60-inch door with 80-inch height is the most economical. Order pre-hung units to reduce on-site labor. Consolidate orders into full-container loads (FCL) to reduce freight costs. Source factory-direct to eliminate distributor markup.

5. How to Evaluate Double Front Exterior Door Suppliers

Supplier evaluation is where most procurement errors occur. Buyers focus on price and lead time, but real risks lie in quality consistency and documentation.

The Supply Chain Landscape

Three channels exist: local distributors, importers/wholesalers, and factory-direct manufacturers. Distributors offer convenience and local support but add a 20–40% markup. Importers offer better pricing but limited customization. Factory-direct offers the best price and full customization but requires the buyer to manage logistics and communication.

Key Quality Indicators for Buyers

When evaluating a manufacturer, request:

• Technical datasheets with material specs, glass U-factors, and hardware ratings.
• Test reports for air-tightness, water-tightness, and wind resistance (AAMA/WDMA/CSA certification).
• Production capacity and current workload — an overbooked factory will rush your order.
• Sample doors for physical inspection before bulk production.
• References from other importers or contractors in your market.

Red Flags to Avoid

Avoid suppliers who cannot provide test reports. Avoid suppliers who quote without asking for your rough opening size and wall thickness. Avoid suppliers who promise a 2-week lead time for custom doors — it is not realistic. Avoid suppliers who cannot produce a packing list and proforma invoice in English.

Questions to Ask Before Ordering

• What is the moisture content of the wood at finishing?
• What is the tolerance on frame squareness?
• How is the astragal attached — fixed or removable?
• What is the warranty on the finish and hardware?
• What is the lead time for a repeat order?

6. Relevant Industry Standards and Certifications

Compliance is not optional. Every door supplied for a construction project must meet applicable codes and standards. Verify that your supplier can provide:

• ISO 9001:2015 — Quality management systems certification. Baseline for any reputable manufacturer.
• CE marking — Required for sale in the European Economic Area. Indicates conformity with health, safety, and environmental standards.
• AAMA/WDMA/CSA 101/I.S.2/A440 — North American standard for windows and doors, covering air, water, and structural performance.
• ENERGY STAR — Voluntary certification for energy-efficient products, referencing U-factor and SHGC ratings.
• Miami-Dade County approval — Required for doors in hurricane-prone regions of Florida. Rigorous testing protocol.

Fire-rated doors require additional certifications, typically from UL or Intertek. The frame, seals, and hardware must be rated together as a system.

7. Production Process: From Raw Material to Finished Doors

Understanding the production process helps buyers judge whether a factory can deliver consistent quality.

CNC Machining and Panel Construction

For wood doors, the process starts with kiln-dried lumber milled to the correct moisture content. Stile-and-rail components are cut and profiled using CNC routers, and mortise-and-tenon joints are machined to tolerances of ±0.5 mm. Panels are assembled with waterproof adhesive and clamped until cured.

For aluminum doors, profiles are cut to length and machined for drainage holes and hardware cutouts. Profiles are assembled with corner keys and structural adhesive, then thermal-break polyamide strips are crimped in place.

Surface Treatment

Wood doors are sanded through progressively finer grits, then sealed and finished, typically with UV-cured polyurethane for durability without yellowing. Aluminum profiles are powder coated in a multi-stage process: cleaning, chemical pre-treatment, electrostatic powder application, and curing at 200°C. This finish resists chalking and fading for 20+ years.

Assembly and Glazing

Door panels are fitted into the frame, and hinges are installed with load-rated screws. Glass is set with structural silicone and held with glazing beads. The astragal is installed, and the multi-point locking system is tested for alignment. Each unit is inspected for air leakage, water penetration, and wind resistance.

8. Customization and OEM/ODM Options

B2B buyers often need doors that match specific architectural drawings or local building codes. A factory that accommodates custom specifications is worth more than one that only produces standard sizes.

Customization Capabilities

Full customization covers size, color, glass, and hardware accessories. Buyers should be able to specify non-standard widths, custom arch tops, or specific RAL colors for aluminum frames. The factory should offer adjustable profile structures and fittings to match local building codes.

OEM vs. ODM

OEM (Original Equipment Manufacturing) means the buyer provides drawings and the factory manufactures to those exact specs. Suitable for buyers with established products. ODM (Original Design Manufacturing) means the factory uses its own design team to develop custom profiles based on buyer requirements. Suitable for buyers needing design support.

Private Label and Bulk Supply

Private label allows the buyer to brand the product as their own for distribution. Common among importers and wholesalers. Bulk supply for construction projects requires consistent lead times and the ability to handle large-volume orders without quality fluctuation.

9. Ordering Process: MOQ, Lead Time, and Shipping

The ordering process for factory-direct sourcing is straightforward but requires planning.

Minimum Order Quantity (MOQ)

MOQs vary by factory and product type. Some factories accept orders as small as 10 units for standard sizes. Custom doors typically require a higher MOQ, often 20–50 units, because the factory must set up new tooling and profiles.

Lead Time

Standard lead times range from 4 to 8 weeks, depending on material and customization level. Custom wood doors with arch tops and carved details can take 10–12 weeks. Buyers should order 8–10 weeks in advance to secure project timelines.

Shipping and Documentation

A factory with foreign trade experience will provide a packing list, proforma invoice, and full customs documents. Shipping can be FCL (Full Container Load) or LCL (Less than Container Load). FCL is more cost-effective for large orders; LCL suits smaller quantities.
