Why Homeowners Choose Patio Doors

Patio doors do more than just look good — they improve how your home feels and functions. 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 resale value 
  • 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 advanced weather seals, thermally broken frames, and A-rated glazing, our doors keep your home warm in winter and cool in summer.

 uPVC vs Aluminium — Which Is Right for You?

Choosing between uPVC and aluminium patio doors depends on your budget, style preference, and performance needs:

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.

Dedicated Residential & Commercial Glazing Services

At GLITZ Windows & Conservatories Ltd, we pride ourselves on delivering personalized double glazing solutions for both residential and commercial clients. Our commitment to quality, innovation, and customer satisfaction drives everything we do. From consultation to installation, we ensure durable, energy-efficient, and visually appealing results that stand the test of time.

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.

 Sliding Patio Doors

Sliding patio doors remain one of the most popular choices for homes in Coulsdon and Surrey. 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.

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

Bifold doors are ideal for creating a striking, open-plan living space 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.

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 a cost-effective way to upgrade rear 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.

 Security You Can Rely On

All of the patio doors we supply and install come with robust security as standard. All our patio doors are built with security as a priority, using tested locking systems and reinforced materials. 

  •  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

Poorly fitted doors can lead to significant heat loss and higher energy bills. 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.

 Frequently Asked Questions (FAQs)

Sliding patio doors remain the most widely fitted style due to their versatility and neat, space-saving operation. However, bifold doors have grown enormously in popularity over the past decade, particularly for kitchen extensions and open-plan living areas.

Costs vary depending on size, style, material, and glazing specification. As a general guide, uPVC French doors start from a few hundred pounds supplied and fitted, while large aluminium bifold systems for wider openings can run into the thousands. We always provide a detailed, written quotation after your free home survey, so there are no surprises.

In most cases, replacing like-for-like patio doors falls under permitted development and does not require planning permission. However, if you live in a listed building, conservation area, or are making significant structural changes, you may need to check with your local council. Our team is happy to advise.

A standard patio door replacement is typically completed within one working day. Larger bifold installations or projects involving structural lintel work may take a little longer. We’ll give you a clear timeframe when we visit for your survey.
