What Are Bifold Doors?

External bifold doors are the name in vogue for what you may recognise as folding sliding doors. Also referred to as bifold patio doors or concertina doors, external bifold doors pretty much do what they say on the tin.

They are made from a series of panels that fold like a concertina and are a popular design choice in many homes for connecting an internal space to an external space. Bifold doors can have many panels and run across a track on the bottom of the door frame, sliding across using wheels. They fold away out of sight for a discreet closure, providing an unparalleled method for creating wide-open vistas in the home.

Our Range of Bifold Doors

We are proud to offer beautifully made external bifold doors that can entirely transform your property. The two main options for material are timber and aluminium. Read on below to find out more about the unique benefits of each.

Timber Bifold Doors

Our timber bifold doors are a visually stunning choice and ideal if you want to maintain a more traditional look to the modern bifold. Great for fitting into what may be a heritage property or conservation area, these wooden bifold doors have a truly authentic and timeless design but with minimal maintenance requirements.

Timber is a great choice for those in colder climates as one of the material’s many benefits is its superior insulation and, therefore, energy efficiency. Our timber bifold doors incorporate the most advanced thermal breaks and weather tight seals with multi-point locking systems that ensure maximum compression for increased weather resistance.

We have a range of timber bifold doors with design configurations available up to 10 leafs, that can span up to 10 metres wide, and that can open up the entire side of a property. Our timber bifold doors come in a variety of RAL colours, enabling you to choose the ideal fit for your home’s design.

Our timber doors are all made using sustainable, ethically-sourced materials. We practice sustainability as part of our ethos and make products that stand the test of time.

Aluminium Bifold Doors

Aluminium bifold doors are a stylishly sleek folding door option that can look great in a modern or traditional home. They’re lightweight but just as durable as timber bifold doors.

If you’re looking for a more discreet bifold door option to fit seamlessly into your home, aluminium bifold doors offer a slim profile and a very compact stacking formation which also works to minimise shadows cast by the frames. Aluminium bifold doors also offer more custom design options in contrast to timber bifold doors.

Our aluminium sliding doors are available in low or level threshold designs, which allows for equal floor finishes without compromising on weatherproofing. This also means that any risk of trips or falls is greatly minimised as the bottom of the bifold doors don’t jut out at all.

Our aluminium bifold doors are fitted with reliable locking mechanisms to ensure peace of mind regarding the security of your home. All of our doors are fully weather rated by British Standards and surpass British Building Regulations.

Fully Customisable Bifold Doors

We are delighted to be able to offer a huge range of customisation options on our bifold doors. Our white bifold doors offer a clean, classic look while our black bifold doors can give a sense of modern sophistication. Whatever colour or finish you go for, you’re sure to find the right style for your property with Sash Windows London.

What Are the Benefits of Bifold Doors?

The two main benefits of external bifold doors are the superb levels of natural light they let in and their compact, space-saving nature.

The effortless close and unobtrusive stack of folding sliding doors allow for a beautiful space-saving solution, making a room feel vastly more open and light. Small rooms or small houses can really benefit from the increased visual space that an external bifold door offers. Internal bifold doors are also very in at the moment and are a fantastic option to add aesthetic value and functionality to a shower, for example.

External bifold doors provide the perfect solution for connecting or partitioning an outdoor area. The seamless transition from indoors to outdoors is an attractive feature for anyone looking to bring natural light and a sense of openness to what may be a quite enclosed home, or to continue an open-plan theme.

Not only do these doors have real aesthetic appeal, but they are also energy-efficient, completely secure and high in demand; a bifold door can really increase the value of a property and is entirely worth the investment.

Installing an external bifold door is a relatively simple process, especially with Sash Windows London. All of our bifold doors are all made-to-measure and we aim to provide accurate quotes within 48 hours.

How Much Do Bifold Doors Cost?

At Sash Windows London, all of our external bifold doors are bespoke and made-to-measure so there is no one cost. The considerations we take into account when determining the cost of any bifold door installation are:

  • The materials you choose: One of the benefits of choosing Sash Windows London for your bifold doors is the customisation options. We offer stunning aluminium or timber doors with differing finishing effects to choose from, so you can suit them to your home’s unique design. Read the next section below for more information on our range.
  • The installation size: Each panel on your bifold door will come with an additional cost that affects the final cost of installation. Many bifold doors are installed in kitchens that open up to patios, for example, which commonly use four panels. Conservatories can take more. It completely depends on your property and the placing of your bifold doors.
  • Glass panel glazing type: It’s important to consider weather conditions and temperature when choosing bifold doors with glass, which nearly all external bifold doors are. In many cases, double-glazing may be necessary for the glass panels of your bifold doors due to the effect it has on temperature. Double-glazing uses more glass, as do triple-glazed panels, all of which will affect the cost.

What you’ll be paying for when you choose Sash Windows London for your bifold doors is the highest quality products built to the highest possible standards. Upon purchase, your bifold door comes with the following guarantees:

  • 10-year guarantee on glazing
  • 5-year warranty on hardware
  • 10-year warranty on paint and stain
  • 10-year warranty on workmanship
  • 30-year warranty on timber rot and decay

Whatever it is, we provide surveys and accurate quotes completely free of charge and cater to a wide range of properties and budgets.
