Double Wood Doors Exterior | Custom Factory Direct Manufacturer | Jusen

10 min read

The first question a buyer asks when they see double wood doors exterior in a catalog is rarely about the finish. It is about whether the factory can replicate that finish across 200 units without drift.

We have been answering that question since before most of our competitors opened their doors. The answer lies in how we control the material, the machining, and the testing — not in how we photograph the product.

Here is what we tell buyers when they visit our factory or request a sample batch.

Why Double Doors for Your Exterior Entrance?

Double doors are not a style choice. They are a structural decision that affects how a building handles traffic flow, natural light, and thermal performance.

Aesthetic Symmetry and Grandeur

For villas, hotels, and commercial lobbies, double doors create an entrance that a single door cannot match. The symmetry anchors the facade. But symmetry is only impressive if the two leaves align perfectly. In our factory, we machine both leaves from the same billet of wood, then match them by grain pattern before assembly. This is not something you can achieve with off-the-shelf doors from a distributor. It requires controlling the entire production run.

Our factory offers full customization on size and color to match your architectural drawings. If your project calls for a 1,800 mm opening with a specific RAL color match, we can produce it. If you need a two-tone finish — dark exterior, light interior — that is also within our capability. We do not limit you to catalog options.

Enhanced Natural Light and Ventilation

A double door opens up to 3,000 mm of clear width. That changes how a space breathes. But wider openings also mean larger glass panels, which raises the stakes on thermal performance.

This is where our full customization on glass matters. We can specify double-glazed low-E units, frosted panels for privacy, or decorative glass that complements the wood tone. For projects in hot climates, we use a thermal-break construction in the frame — the same technology we apply to our aluminum system windows — to prevent the glass from becoming a thermal bridge. You get the daylight without the energy penalty.

The Structural Advantage of Wood

Wood is a natural insulator. A 44 mm solid wood slab has better thermal performance than an equivalent aluminum frame with a thermal break. But wood also moves. It expands and contracts with humidity. This is why our adjustable profile structure is critical.

We engineer the door core with engineered wood layers that resist warping, then reinforce the frame with aluminum or steel inserts where local wind load requirements demand it. For coastal projects or high-rise installations, we can increase the core thickness or add a second sealing plane. The wood does the aesthetic work; the engineering does the protective work.

Our Manufacturing Process for Double Wood Doors Exterior

Transparency in manufacturing is the fastest way to build trust with a B2B buyer. Here is exactly what happens to your doors before they reach the port.

Sourcing and Material Selection

Exterior doors fail when the wood has excessive moisture content. We select kiln-dried lumber with a moisture content between 8% and 12%. This range is non-negotiable for exterior applications. If the wood is too dry, it will crack; too wet, it will warp and invite rot.

Our team sources timber globally. For projects requiring specific species — European oak, American walnut, or tropical hardwoods — we leverage our rich experience in foreign trade to procure directly from certified mills. We do not rely on a single supplier. This protects you from supply chain disruptions that delay your construction schedule.

Customization: From Standard Sizes to ODM Projects

We offer both OEM and ODM services. OEM means you provide the drawings and we build to your exact specification. ODM means you can start from our existing designs and modify them — changing the panel layout, the glass configuration, or the hardware branding.

For ODM projects, we can apply your logo to the hardware, engrave your brand on the glass, or even adjust the door profile to match a specific architectural style. This is particularly valuable for distributors who want a private label product without investing in their own manufacturing line.

Pre-Shipment Inspection Protocol

Every batch of exterior doors undergoes our three-part inspection: air-tightness, water-tightness, and wind resistance testing. These are not random spot checks. We test each production run and provide the test report to the buyer.

The air-tightness test measures how much air leaks through the closed door assembly. The water-tightness test simulates rain under pressure to check the sealing system. The wind resistance test applies load to the door face to verify structural integrity. For a double door, this is especially important because the meeting stile between the two leaves is the weakest point. If that joint fails, the entire door fails.

We have seen competitors skip these tests to save cost. The result is doors that whistle in the wind, leak during storms, or sag after a year of use. Our testing protocol exists because we have seen the consequences of skipping it.

Technical Specifications and Hardware Integration

Double wood doors are heavy. A pair of solid wood leaves can weigh 80 to 120 kg depending on size and thickness. The hardware must handle this weight over decades of daily use.

Hardware Options for Heavy Doors

We offer full customization on hardware accessories. For heavy doors, we recommend stainless steel ball-bearing hinges rated for 80 kg per leaf. The hinge count matters — three hinges per leaf is the minimum for doors over 2,200 mm in height. We also install multi-point locking systems that engage at the top, bottom, and center of the door. This prevents warping and improves security.

For commercial applications, we can integrate automatic closers, electromagnetic hold-open devices, or access control systems. We pre-install these during production, so the door arrives ready for wiring, not as a kit that requires a skilled carpenter to assemble on site.

Glass and Glazing Options

We engineer the glazing integration using the same technology we apply to our system windows and casement doors. The glass is not just a panel set into a wooden frame. It is a sealed unit with a warm-edge spacer, desiccant, and a gas fill. We offer double and triple glazing depending on your climate zone.

For projects with acoustic requirements, we can specify laminated glass with a PVB interlayer. For security applications, we can use tempered or even ballistic-rated glass. The frame is machined to accommodate the glass thickness, which means we need to know your glass specification before production begins. Send your requirements to Contact Our Team and we will confirm the engineering details.

Compliance with Local Building Codes

This is where many importers get burned. A door that is perfectly adequate in one country fails inspection in another because the local code requires a specific wind load rating, fire resistance, or energy performance level.

Our adjustable profile structure and fittings are designed to match local building codes of target markets. For European projects, we can configure the door to meet CE marking requirements. For North American projects, we can adjust the frame to accommodate the required insulation values and hardware standards. We do not ship the same door everywhere. We adapt the construction to your market.

The Jusen Advantage: Factory-Direct vs. Middlemen

The difference between buying from a factory and buying from a trading company is not just price. It is control over quality, schedule, and communication.

Competitive Pricing Without Markup

Our direct supply from factory means you pay for the product, not for a middleman’s commission. Trading companies typically add 15% to 30% on top of the factory price. For a container order of double wood doors, that markup translates into thousands of dollars of unnecessary cost.

We work directly with construction project bulk supply clients. When you order from us, you are ordering from the entity that actually produces the doors. This also means we can adjust production details mid-run without waiting for approval from an intermediary who has no authority over the factory floor.

Streamlined Logistics and Documentation

International shipping is not just about loading a container. It is about documentation. We provide the packing list, proforma invoice, and full customs documents required for clearance in your country. We have handled shipments to over 30 countries, so we know the specific documentation requirements for different ports.

We support both FCL and LCL shipment, direct delivery from China factory. For LCL shipments, we consolidate your order with other cargo to fill a container, which is cost-effective for smaller orders. For FCL shipments, your container is loaded at our factory and sealed under our supervision. This reduces the risk of damage or tampering during transit.

Scalability for Projects

Developers and contractors need doors delivered on a schedule, not when the factory gets around to it. We understand this because we have supplied construction projects where a delay in door delivery would hold up an entire building handover.

Our production capacity allows us to run multiple lines simultaneously. We can produce 500 units of a standard design in four to six weeks, and custom designs in eight to ten weeks depending on complexity. We control the schedule because we control the factory. If a project timeline shifts, we can accelerate production or hold inventory in our warehouse until you are ready for delivery.

Frequently Asked Questions

Can you match custom sizes for non-standard openings?

Yes. We are a full-customization factory. We can adjust the size and profile structure to fit your rough opening within a tolerance of ±2 mm. Send your drawings to Request a Quote and we will confirm the manufacturing feasibility.

What is the MOQ for a bulk order of double wood doors?

We work with B2B clients on project volumes. The MOQ depends on the specifications — a standard design with minor size adjustments can have a lower MOQ than a fully custom ODM project. For initial orders, we can discuss LCL shipments to help you test the market before committing to a full container.

How do you ensure the doors survive sea freight and arrive without damage?

Our packaging is designed for export. Each door is wrapped in a moisture barrier, then placed in a reinforced wooden crate with foam padding at all corners. For high-value units, we add an additional layer of corner protection and vibration-dampening material. We have shipped to humid ports, cold climates, and rough sea routes without reported damage.

Can you provide hardware that meets European or North American standards?

Absolutely. We offer full customization on hardware accessories and our adjustable profile structure allows us to install multi-point locking systems that comply with the building codes of your target market. We also provide certification documents for the hardware components upon request.

What is the typical lead time for a production run?

Lead times vary based on quantity and customization level. A standard double wood door exterior with minimal customization can be produced in three to four weeks. A fully custom ODM project with special glass, hardware, and finish can take six to eight weeks. Because we are the factory, we control the schedule and can communicate accurately about delivery milestones.

Are wood doors the right choice for high-humidity environments?

Wooden doors are not always the cheapest option. For high-humidity areas, buyers should prioritize moisture resistance over appearance. We can treat the wood with a marine-grade sealant and use stainless steel hardware to resist corrosion. However, if the project is in an environment with constant standing water or extreme temperature swings, an aluminum door might be a better choice. We manufacture both, so we can advise you honestly on the best material for your climate.

Choosing the Right Configuration

Here is a decision guide based on what we see in the field:

Choose a double wood door exterior if:

• Your project requires a premium aesthetic for villas, hotels, or executive offices.
• You need natural light and ventilation with a wide opening.
• Your building design demands the thermal insulation of wood.

Choose an aluminum door instead if:

• The project faces extreme humidity, salt air, or chemical exposure.
• You need a slimmer frame profile for maximum glass area.
• The local code requires a specific fire rating that wood cannot meet.

Choosing a supplier is not about finding the cheapest quote. It is about finding a factory that can deliver the quality you promised to your client. We have been doing this for over a decade, and we will tell you when a product is not the right fit for your project. That honesty is part of the service.
