Understanding French Doors


Definition and History


French doors, also known as French window doors, refer to hinged doors with glass panes extending most of their length. Instead of a single door panel, French doors have two door panels that open in the middle.

The origins of French doors date back centuries in Europe. Historic French architecture commonly incorporated these doors that opened onto balconies and patios, allowing an effortless transition between indoors and outdoors.

Over time, the elegance and functionality of French doors gained popularity worldwide in residential and commercial settings. Today, they are a sought-after way to infuse natural light, showcase views, and add character to any space.


Benefits of French Doors


There are many excellent reasons to choose French doors:

  • Increased Natural Light – The expansive glass panes of French doors maximize daylight entering your home. This creates a brighter, airier environment.
  • Improved Ventilation – French doors facilitate air circulation and fresh air flow when open. Their breezy, open-air feel is perfect for transitions between rooms.
  • Enhanced Curb Appeal – Stylish French doors make an eye-catching statement from the curbside. They add instant aesthetic appeal and charm to your home’s exterior.
  • Light and Views – French doors invite your eye to wander beyond them. They frame beautiful outdoor views and vistas from within your home.
  • Seamless Indoor/Outdoor FlowFrench doors extend your living space outdoors. Closed, they still maintain a visual connection outside.

With this winning combination of form and function, it’s easy to see why French doors are a popular pick for homeowners. Keep reading to learn more about choosing the perfect set.

Choosing the Right Material


One of the most important decisions you’ll make is choosing the suitable French door material. Key factors include maintenance requirements, durability, insulation, cost and aesthetics. Let’s compare the benefits of different materials:


Wood, PVC, Aluminum: Pros and Cons

  • Minimal upkeep required
  • Resists moisture, rotting, and insects
  • Affordable compared to wood
  • Available in various colours and finishes
  • Energy efficient with multi-chamber construction
  • Easily cleaned with soap and water


  • Can warp at high temperatures

When choosing aluminium, opt for thermally broken frames filled with insulation to limit heat/cold transfer.


Latest Trends in Materials


Today’s eco-conscious homeowners can also find French doors made sustainably from:

  • Recycled wood – Crafted using reclaimed barn wood, demolition lumber, orchard cuttings, and more.
  • Bamboo – Made from quickly renewable bamboo stalks. Offers strength similar to some hardwoods.
  • Composite – Blends synthetic resins with wood fibre/particles. Mimics wood with less maintenance.
  • Fibreglass – Glass fibres bound in a weather-resistant polymer resin. It won’t warp, shrink, or swell.

Sizing and Style Considerations


Sizing and Style Considerations

Before purchasing French doors, you must determine the correct size and style options. Consider the following:


Measuring for French Doors


Precision measurements are crucial for proper French door installation and functionality. Be sure to measure:

  • Opening Width – Measure across the centre of the door frame opening. Standard widths for French door units are 30-36 inches per door.
  • Opening Height – Measure floor to top of the frame. Standard heights range from 6’8″ to 8 feet.
  • Frame Depth – Depth required for installation into the opening. Often 4 9/16″ to 6 9/16″.
  • Floor Clearance – Minimum 1/2″ space between bottom of door and floor.

These measurements will help you choose an appropriately sized French door unit for your opening.


Styles and Designs


French doors are available in an array of styles to match your home’s architectural character:

  • Traditional – Classic French door style with divided lights and ornate hardware.
  • Contemporary – Sleek, modern look with clean lines and large glass panes.
  • Rustic – Barn door-style with imperfections and raw, reclaimed wood.
  • Cottage – Romantic look with smaller glass sizes, grillwork, and a distressed painted finish.
  • Transoms/Sidelites – Flank doors with matching stationary windows for added light.
  • Arched – Eye-catching curved top shape. Requires wider radius opening.

There are also numerous glass patterns and door hardware options to customize your French doors’ look.

Installation Types


French doors can be installed to open either inward or outward. Considerations include:


In-swinging vs. Out-swinging Doors



Doors open into the room.


  • Take up zero exterior space
  • Offer better security and weatherproofing
  • Allow additions like screens without altering the exterior


  • Reduce interior floor space when open
  • Hardware is prone to damage from internal collisions


Doors open outward.


  • Don’t reduce interior space
  • Hardware avoids interior damage
  • Allow wider openings


  • Require exterior clearance for doors to open fully
  • Less weatherproof and secure than in-swinging
  • Additions like screens require modifying the exterior

In-swinging doors work well in rooms with ample floor space. Out-swinging doors maximize tight indoor areas. Consider your room dimensions, furniture layouts, and exterior clearance when deciding.

Security Features


Understanding French Doors

Security is a priority for many homeowners. Fortunately, modern French door designs offer robust security options:


High-Security Locks and Advanced Features


  • Multi-point locking systems engage multiple heavy-duty bolts into the door frame for reinforced security. Look for at least three locking points.
  • Deadbolts offer added protection at the door’s edge or top/bottom corners. Opt for a 1″ throw length for maximum strength.
  • Laminated glass layers make doors far harder to break through than traditional glass. Burglar-resistant glazing provides further security.
  • Internal glazing beads prevent glass removal/entry from the exterior.
  • Steel/reinforced frames, metal mesh screens, and security bars provide additional security layers.


Latest Trends in Security


  • Innovative technology enables locking/unlocking doors remotely via smartphone.
  • Alarm sensors trigger alerts if glass or doors are breached.
  • Facial recognition and fingerprint scanning technology verify authorized access.
  • Burglar-resistant glass is tested to withstand prolonged attack before compromising.

By leveraging the latest security innovations, today’s French doors can deliver ironclad protection and peace of mind.

Energy Efficiency and Eco-Friendliness


Environmentally conscious buyers should look for energy-efficient French door models:


Energy-Efficient Designs


  • Insulated Glass – Multiple glass panes separated by gas-filled spaces minimize heat/cold transfer. Look for ENERGY STAR certification.
  • Insulated Frames – PVC and fibreglass or aluminium models with thermal breaks prevent energy leaks.
  • Weatherstripping – Tight seals block drafts and water infiltration around doors.
  • Low-E Coatings – Microscopically thin metallic layers reflect infrared light for improved insulation.
  • Argon/Krypton Gas – Inert gas injected between panes enhances insulation properties.
  • ENERGY STAR Certification – Ensures doors meet strict energy efficiency standards for U.S. climates.
