Why Homeowners Choose Patio Doors

Patio doors do more than just look good, and they look good doing it. Here are just some reasons why thousands of UK residents are choosing patio doors:

• Bring in lots of natural light to make rooms look larger and more welcoming
• Seamlessly integrate indoor and outdoor spaces for effortless entertaining
• Boost your property’s style and potential resale value to your home
• Benefit from improved energy efficiency with our latest double-glazing and triple-glazing technology
• Enhanced security features, such as standard multi-point locking
• Low-maintenance uPVC and aluminium frames, no painting or sealing required

New patio doors are designed to do just that, perform. With first-rate weather seals, thermally broken aluminium, and A-rated glass, you can enjoy a cozy home in the winter, and stay cool in the summer, while still enjoying the beauty of your home all year round.

Our Range of Patio Doors

We have three main external glazed patio door styles, each of which can complement different rooms and architectural styles. Not sure which one would be best for you? Well, we can help.

1. Sliding Patio Doors

Sliding patio doors are still one of the nation’s favourite choices. They use a smooth tracking system that allows one or several glazed panels to slide horizontally behind a fixed panel, perfect for rooms where there isn’t enough space to open a door.

•  Best for: smaller gardens, narrow openings, or rooms where floor space is limited
•  Available in: uPVC and slim-profile aluminium frames
• Glass options: double glazed as standard; triple glazing available on request
•  Popular colours: white, anthracite grey, black, and dual-colour finishes

Sliding patio doors offer a clean, contemporary aesthetic that suits both modern extensions and traditional homes. The low-threshold design also makes them an excellent choice for accessibility.

2. Bifold Patio Doors

Bifold doors are the go-to choice when you want maximum opening width. A series of panels folds neatly against itself and stacks on one or both sides, creating a wide, unobstructed aperture that truly opens your home to the outside.

• Best for: wider openings, open-plan living spaces, new extensions and orangeries
• Available in: aluminium (slim sightlines for a premium look) and uPVC
• Panel configurations: 2, 3, 4, 5 or 6 panels, tailored to your opening
• Popular colours: anthracite grey, white, black, and RAL custom colours in aluminium

If you want to create a real wow factor in your kitchen-diner or living room, bifold doors deliver it. They’re also a smart choice for bringing light into darker rooms, even when the doors are closed, the expansive glass area keeps spaces feeling airy and bright.

3. French Patio Doors

French doors are a timeless classic. Two glazed panels open outward (or inward) from a central point, offering an elegant, traditional look that works beautifully on period and cottage-style properties. They’re also one of the most cost-effective ways to upgrade a back or side access.

• Best for: standard-width openings, traditional or period homes, budget-conscious upgrades
• Available in: uPVC and aluminium; wooden-effect finishes available in uPVC
• Security: multi-point locking as standard; optional shootbolts for added protection
• Popular colours: white, cream, grey, green, and black

French doors can also be paired with side panels or a top transom light to increase the amount of glazing in an opening, a great way to maximise light without a full structural change.

 uPVC vs Aluminium — Which Is Right for You?

Both uPVC and aluminium are excellent, low-maintenance frame materials, but they do have different strengths:

uPVC Patio Doors

• Excellent thermal insulation, ideal for energy efficiency
•  Lower price point, making them a popular choice for value-led projects
• Wide colour range, including woodgrain foil finishes
• Robust, durable and virtually maintenance-free

Aluminium Patio Doors

•  Slim, minimalist sightlines for a premium contemporary look
• Exceptionally strong, allowing larger glazed areas with narrower frames
• Thermally broken profiles deliver outstanding energy performance
• Virtually unlimited colour choice via powder-coating (RAL palette)
• Long lifespan and superior resistance to warping or discolouration

Not sure which to choose? In general, aluminium suits modern, open-plan spaces where slimmer frames and larger glass areas are a priority. uPVC is an excellent all-round performer and is particularly popular where budget is an important consideration.

 Security You Can Rely On

All of the patio doors we supply and install come with robust security as standard. You should never have to compromise on safety for the sake of style — and with Glitz Windows, you don’t.

•  Multi-point locking systems on all doors
• Toughened or laminated safety glass as standard
• Anti-lift and anti-jimmy features built into frames
• Shoot bolt systems available for bifold and French doors
• All products comply with current UK security standards

 Energy Efficiency & Thermal Performance

The warmth of your home is important, and doors are a big part of ensuring you don’t pay over the odds for keeping your home comfortable. This is because a poorly functioning door can lose heat out of your home in a way that is both literal and figurative. This is why we fit all of our patio doors with high-performance double glazing as standard at Glitz Windows.

What you can expect from our range:

• A-rated double-glazed units
• Low-E glass to minimize heat loss and reduce glare from UV light
• Argon gas-filled cavities to improve insulation
• Thermally broken aluminium profiles for maximum performance
• Warm edge spacer bars to eliminate condensation on the glass

Not only will choosing energy-efficient patio doors from us save you money, it will also benefit the environment by reducing your carbon footprint. There is a noticeable difference in comfort levels after installation, particularly in rooms that were previously draughty.
