What’s the difference between inline and lift-and-slide?

Inline slides on tracks; lift-and-slide raises the sash for effortless movement and enhanced sealing when closed.

Are large panels possible?

Yes—aluminium frames allow wide spans and tall doors with slim interlocks.

Are sliders energy-efficient and weather-tight?

Thermal breaks, low-E glass and quality seals ensure low U-values and high weather performance.

What security options are available?

Multi-point locks, anti-lift devices and laminated glass for improved security.

Can I have a flush threshold?

Low thresholds available; we balance accessibility with weather performance.

Do you repair existing sliding doors?

Yes—rollers, tracks, locks and realignment services offered.

5 benefits of sliding doors for homes & businesses:

Maximise Space in your Architectural Design

Unlike most doors, sliding doors open neatly to one side, saving you a lot of space when compared to doors that open and close into a room. Make the most of the space you have while adding a touch of style and openness to your property.

Increase Energy-Efficiency

Sliding doors can be partially opened, meaning you can regulate airflow and maintain a comfortable indoor temperature, especially during the warmer months. At Instant Windows & Doors, we install double-glazed sliding doors for homes and businesses across the southeast that prevent cold air from entering and warm air from escaping. Reduce heat loss by over 70% and enjoy the difference in your bank account at the end of each month.

Create a Seamless Indoor / Outdoor Connection

Sliding doors create a feeling of openness and connection to your outdoor space. They are designed with large glass panels that allow unobstructed views and easy access to patios, balconies or gardens. Enjoy the beauty of the great outdoors from the comfort of your home or office.

Increase the Security of your Property

At Instant Windows & Doors, we install sliding doors with advanced locking systems to deter opportunists from breaking in. Increase security at home or work with our high-performance sliding door security systems, designed to keep you and your loved ones safe.

5 Benefits of Sliding Doors for Homes & Businesses

Enhance the Appearance of your Property

Sliding doors come in various designs, materials and finishes, offering flexibility to suit different architectural styles, interior design themes and colour schemes. Add a modern and stylish touch to your home or office premises while also increasing its value and elegant feel.

Choose a colour or opt for a traditional timber effect to make your sliding doors look like authentic wooden frames. The choices are endless; select the handle that best suits your taste! Recessed handles, D-shaped handles, bar handles, finger pull handles and flush pull handles are just a few of the handles we stock. Our sliding door installers will also present you with a range of glazing designs, including anything from leaded and obscured to bevelled glass!

The sky is your limit when it comes to customising your double-glazed sliding doors.

Sliding Doors FAQs: Modern Aluminium & uPVC Patio Door Solutions

What are the benefits of sliding doors?

Sliding patio doors maximise natural light, provide uninterrupted views, and save space since panels slide rather than opening in or out. With slim sightlines and large glazed panels, they create a modern, open-plan feel that seamlessly connects home and garden.

Are sliding doors energy-efficient?

Yes — our sliding doors use thermally broken aluminium or multi-chambered uPVC frames combined with double or triple glazing. They achieve excellent U-values to keep homes warm in winter and cool in summer while reducing energy bills.

How secure are sliding patio doors?

Our sliding doors come with multi-point locks, reinforced frames and anti-lift tracks. They are fitted with toughened or laminated safety glass and are available with PAS 24 and Secured by Design security upgrades for maximum peace of mind.

Do sliding doors need planning permission?

Most like-for-like replacements don’t require planning permission. However, if you’re creating a new opening, extending your home, or live in a conservation area or listed property, approval may be required. We’ll advise during your free survey.

Can sliding doors be customised?

Yes — our sliding patio doors are fully bespoke. You can choose frame material, size, number of panels, opening configurations, colours (including dual-colour frames), glazing options and hardware to suit your home and lifestyle.

Are sliding doors easy to maintain?

Yes — aluminium and uPVC sliding doors are low-maintenance. They won’t warp, rot or rust and only need occasional cleaning of glass and tracks to keep them smooth and stylish. Optional self-cleaning glass is also available.

How much do sliding doors cost?

Prices vary depending on material (aluminium or uPVC), size, configuration, and glazing. Aluminium slimline sliding doors are typically a premium option. We provide free, itemised quotes and offer finance options (subject to status).

How long does it take to install sliding doors?

Most sliding door installations take around 1–2 days. Projects involving structural alterations, such as enlarging openings or adding steels, may take longer. We’ll confirm timelines as part of your quotation.

Do sliding doors add value to a property?

Yes — sliding doors increase a home’s kerb appeal, natural light and connection to outdoor space. As a sought-after modern feature, they can also increase the resale value and desirability of your property.

What guarantees do you provide with sliding doors?

All sliding door installations include a 10-year insurance-backed guarantee, plus manufacturer warranties on frames, glazing and hardware. Installations are also FENSA-registered where applicable, ensuring full compliance with Building Regulations.
