Oak French Doors: Timeless Appeal and Modern Timber Alternatives

Oak French doors are a benchmark for quality, beauty and durability in high-end residential and commercial projects. This guide explores why oak is such a popular choice, how it compares to other premium timber species, and how Lomax + Wood can help you specify the right material for your project.

Why oak French doors set the standard

When architects, developers and housebuilders think about external French doors for a premium project, oak is often the first material that comes to mind. And for good reason.

Oak French doors carry a timeless charm that works across a wide range of interior design styles, from traditional period properties to contemporary new builds. The natural beauty of the grain, the warmth of the tone, and the sheer solidity of the material make oak doors a popular choice for discerning clients who want their external doors to make a statement.

Oak is also exceptionally durable. It is naturally resistant to moisture, fungal decay and insect damage, making it well suited to the demands of external French door installations where weather performance matters.

For living rooms that open onto a garden, or dining room spaces that connect to a terrace, oak French doors offer a classic French door design that combines aesthetic appeal with robust real-world performance.

The case for timber French doors beyond oak

Oak is an excellent material, but it is not the only option worth considering. A well-specified timber French door can be crafted from a range of hardwood and softwood species, each with distinct performance and sustainability characteristics.

At Lomax + Wood, we offer French doors in:

• Engineered Oak – All the visual appeal of solid oak with improved dimensional stability. Engineered oak is less susceptible to warping and movement, making it an excellent choice for large double doors or external bifold doors in exposed locations.
• Sapele – A rich, ribbon-grained hardwood that offers a warm reddish-brown finish. Sapele is highly durable and works beautifully as an alternative to oak for high-end projects.
• Engineered Hardwood – A versatile option that delivers durability and stability across a variety of styles and finishes.
• Engineered Redwood – A reliable, cost-effective softwood option that performs well when properly finished and maintained.
• Accoya – A modified timber that undergoes acetylation to dramatically improve its durability and dimensional stability. Accoya carries a 50-year above-ground guarantee and is considered one of the most sustainable timber options available.

Each species has its own character. The right choice will depend on your project’s aesthetic requirements, the level of maintenance your client is prepared to commit to, and the environmental credentials required.

Oak vs. alternative hardwoods: a practical comparison

For conservation areas or listed buildings, oak and sapele tend to be the preferred choices due to their traditional appearance and acceptance by planning authorities. For contemporary new builds where a modern twist is required, Accoya or engineered hardwood finished in a RAL colour of choice can deliver excellent results.

Sustainability and responsible sourcing

Timber is one of the most sustainable building materials available, but the source of that timber matters enormously.

At Lomax + Wood, environmental responsibility is central to our manufacturing philosophy. We source all timber used in our bespoke windows and doors with full Chain of Custody certification (FSC® or PEFC), ensuring complete traceability throughout the entire supply chain, from the forest to the finished product.

This is not simply a box-ticking exercise. For architects specifying products for BREEAM-rated buildings, planning applications in sensitive areas, or projects with a clear environmental brief, full Chain of Custody certification provides the documented evidence needed to support those credentials.

Performance specification: what to expect from Lomax + Wood French doors

Our external oak French doors and alternative timber French doors are designed and manufactured to meet current building regulations and the demands of high-performance residential and commercial projects.

Standard specification includes:

• Factory double glazed units: 4/16/4 toughened/toughened Low-E argon fill
• Whole product U value of 1.4 W/m2K, meeting Part L requirements
• Factory hung on Nico 3D fully adjustable hinges
• Espagnolette locking, latch and mortice deadlock as standard for peace of mind
• Fully weather-stripped for thermal and acoustic performance
• CE Marked to EN 14351-1 + A1:2010
• Performance tested to BS6375 Parts 1, 2 and 3

Glazing options include:

• Clear glass (toughened)
• Low-E glass for improved energy efficiency
• Acoustic glass for sound insulation
• Laminated glass for added security

Glass panels can be specified with clear glass for maximum natural light, or with acoustic glazing where the project demands it. For external French doors facing a busy road or urban environment, acoustic glass is well worth considering.

Opening configurations:

• Open out as standard, right-hand leaf opening first
• Open in as an option
• Master leaf configurations available
• Fanlight and sidelight panels available

Design flexibility for every project

One of the strongest arguments for specifying timber French doors is the level of customisation available. Unlike mass-produced external doors or patio doors, Lomax + Wood’s made-to-order approach means every door is built to exact project requirements. This means that from finishes to security options, we can help you find the ideal solution for your project.

Customisation options include:

• Made-to-measure sizing for any opening
• Choice of timber species including engineered oak, solid oak, Accoya and more
• RAL colour of your choice, or a dual finish (different colours internally and externally)
• Stained or painted finishes
• Ovolo or alternative glazing bar profiles
• Raised and fielded panels or flush doors
• Mobility threshold options
• Hardware finishes including polished chrome, satin chrome and more

All windows are made using responsibly sourced FSC® or PEFC certified timber including Engineered Redwood, Hardwood, Oak or Accoya, with custom sizing and various colour finishes available. Each product is made to order, allowing us to meet specific architectural requirements while incorporating practical features such as secure locking systems, durable finishes, and appropriate glazing options to improve comfort and efficiency.

Frequently asked questions

Are oak French doors suitable for listed buildings and conservation areas?

Yes. Timber French doors in oak or sapele are frequently approved for use in listed buildings and conservation areas. Lomax + Wood has experience supplying and installing timber doors on period, listed and conservation projects across Greater London, the South East and throughout the UK.

How do oak French doors compare to bifold doors?

French doors and bifold doors serve different purposes. French doors are double doors that open from a central point, whereas bifold doors fold back in sections to create a wider opening. For a classic, traditional aesthetic, French doors are often preferred. For maximum open space between interior and exterior, bifold doors or external bifold doors may be a better fit. We can advise on the right solution for your project.

What is the difference between internal and external French doors?

External French doors are fully weatherproofed with sealed glazing, multi-point locking and weather-stripped frames. Internal French doors or interior french doors are designed for use inside the home, often as room dividers between a living room and dining room, or as interior double doors to a hallway. They are not built to the same weather performance standard as external doors.
