What Are Double Doors?
Double doors—sometimes called French doors or double patio doors—feature two hinged doors that meet in the middle and open out (or in) from the centre. They’re a timeless way to create flow between your home’s interior and exterior, or zone off space inside your home in style.
There are two main types of double doors: internal and external. External double doors—like front entrances, patio or garden doors—are designed to provide security, weather resistance, and thermal efficiency. Internal double doors, on the other hand, are typically used to separate living areas within the home, offering a stylish way to divide open-plan spaces while maintaining light and connection between rooms.
Why Double Glazed Doors Make Sense
Here’s why upgrading to double glazed doors is a win-win:
- Thermal efficiency: Keeps your space warm in winter, cool in summer.
- Noise reduction: Great if you’re near traffic or a busy garden.
- Security: Toughened glass, multi-point locks, and PAS 24 standards.
- Style versatility: Choose modern minimalist or classic traditional finishes.
French Doors: The Classic Double Door
French doors are the original double glazed doors—refined, symmetrical, and full of charm. Ideal for garden access or a light-filled dining room, they’re equally at home in period cottages or new builds.

Pros and (Past) Cons of Double Doors – and Why Ours Are Built Different
Double doors are a brilliant feature in any home—but we know they’ve come with a few misconceptions in the past. Here’s a breakdown of the benefits, the typical concerns, and how GFD Homes‘ range of high-performance double doors solves every issue.

Past Concerns — Sorted
Some of the older myths about double doors still float around—but here’s why they don’t apply to ours:
“They’re not secure enough.”
That might have been true a decade ago—but not now. All of our double doors are fitted with advanced multi-point locks, many meet PAS24 and Secured by Design standards, and include reinforced frames and laminated glazing where required. Whether you choose Solidor, Smart, or Deceuninck, you’re investing in top-tier security.
“They’ll need loads of upkeep.”
Not the case with ours. From low-maintenance uPVC to powder-coated aluminium and woodgrain composite doors, these systems are designed to offer greater resistance to fading, warping, and weather damage—giving you more style with less maintenance.
“They’ll make my home cold.”
Not with our tech. Every double door in our range is double glazed as standard, with options for triple glazing, thermally broken frames, and warm-edge spacers to lock in heat and keep energy bills low.
