Planning a spring project while the weather is still chilly is a smart move. If you are comparing bi‑folds with today’s sleek sliding and corner-opening systems, you are not alone. The goal is simple, more glass, better views, excellent thermal performance and smooth day-to-day use, all without blowing the budget. Here is a clear, no-nonsense guide to help you choose the right option for your home.

The quick answer, trends and best alternatives

• What is the new trend instead of bifold doors? The standout trend is slimline sliding doors. They give you ultra-narrow sightlines and huge glass panels for an uninterrupted view, perfect for modern extensions.
• What is a better option than a bifold door? It depends on your priorities. For the best views and wide spans, go slimline sliders. For dramatic architectural openings, choose corner-opening sliders. For characterhomes or tighter budgets, aluminium or uPVC French doors can be ideal.
• What is a cheaper alternative to bifold doors? Well-specified uPVC French doors are often the most budget-friendly. Standard sliding patio doors can also cost less than large multi-panel bi‑folds, while stilldelivering a wide opening.
• Are aluminium bifolds better than uPVC? Aluminium wins for strength, slim frames, colour stability and long-term reliability, especially on wider spans. uPVC can be cost-effective for smaller openings, but it will notmatch aluminium for slender sightlines or rigidity.

Where bi‑folds still shine

Bi‑folds remain brilliant for summer living. If your top priority is an opening that almost disappears, bi‑folds deliver a near full-width aperture on warm days. They create an open-air feel for BBQs, parties and easy gardenaccess. Well-designed aluminium bi‑folds with thermal breaks and quality hardware also perform strongly on security and energy efficiency.

If your opening width is modest, say 2.4 to 3.6 metres, bi‑folds can provide the widest clear opening relative to the total span. This is especially useful where the garden or patio is your main entertaining area.

The drawbacks of bi‑folds to weigh up

• More framing, less glass. With multiple panels and hinges, you will see more vertical lines than with sliders.
• Stack space. When opened, panels need to park somewhere. You will need clear wall space inside or out.
• Threshold planning. Low thresholds are possible with the right preparation, but they need accurate surveying and careful installation to maintain weather  performance.
• Cost on very wide spans. As openings grow, panel counts rise and so does complexity and budget.

If clean sightlines and all-season views matter most to you, consider sliders.

Slimline sliding doors, best for uninterrupted views

Slimline sliders excel at the “glass wall” look. They are the new favourite for kitchen-diners and contemporary extensions because they minimise frame and maximise your view. Many systems can carry large panes that glide with fingertip ease, thanks to strong aluminium profiles and advanced running gear.

• Sightlines. Centre interlocks as slim as 20 to 30 mm are available on premium systems, so the frame almost disappears.
• Wide spans. Two or three panels can cover four, five or six metres with fewer breaks in the view than a multi-panel bi‑fold.
• Year-round enjoyment. On colder days you still enjoy bright, panoramic glass without the visual clutter of multiple mullions.
• Thermal performance. Double or triple glazing with warm-edge spacers, argon fills and thermally broken aluminium keeps heat in, without the old compromises.

If you love a calm, minimal look and want to frame your garden like a picture, slimline sliders are hard to beat.

Corner-opening sliders, the statement choice

Corner-opening systems remove the corner post and let two glazed elevations meet with a seamless glass-to-glass look. When opened, the corner glides away for a spectacular, indoor-outdoor effect.

• Design impact. Perfect for extensions with wraparound views.
• Flexible layouts. Choose fixed and sliding combinations to suit furniture and traffic flow.
• Engineering matters. Aluminium strength, correct lintel support and precise installation are essential. With Clearview 2000, you get expert surveying and tidy, professional fitting so the finish matches the ambition.

Choose a corner system if you want a real wow factor and your space can support it structurally.

Aluminium French doors, a stylish and cost-smart option

French doors suit period homes and contemporary spaces that do not need a wall-to-wall opening. They are often the most budget-friendly way to refresh access to the garden, offer excellent ventilation for everyday use and look fantastic with slim aluminium frames or quality uPVC.

• Best for character. Retain traditional proportions while upgrading energy performance.
• Practical day to day. Quick to open, great for popping in and out with kids or pets.
• Budget control. Typically lower cost than large bi‑folds or high-spec sliders.

If you need to stretch your budget or prefer classic styling, French doors are a strong alternative.

Security, materials and specs to look for

• Materials. Premium aluminium offers slim sightlines with excellent strength, colour stability and minimal maintenance. uPVC remains cost-effective and thermally efficient, especially for standard French and patio
  doors.
• Security. Look for multi-point locking, anti-lift tracks on sliders, and laminated glazing options. Many of our systems meet or exceed Secured by Design requirements.
• Thermal performance. Ask about U‑values, thermal breaks, warm-edge spacers and triple glazing. The right spec reduces heat loss and helps with winter comfort.
• Operation. Quality rollers and tracks ensure smooth, quiet motion and long-term reliability.
