Bifold Doors in South Wales – Modern, Slimline, Made-to-Measure

Bifold doors are one of the most sought-after upgrades for South Wales homes, creating a seamless connection between indoors and outdoors. Made from multiple folding panels, they open wide to bring natural light and fresh air into your home, making them ideal for modern living.

At Daimant, we supply and install aluminium and uPVC bifold doors across Caerphilly, Cardiff, and the wider South Wales area. With slim frames, secure locking systems, and energy-efficient glazing, our bifold doors are built for year-round comfort and style.

• Supply and installation of uPVC and aluminium bifold doors.

• Available in 3-panel, 4-panel, and larger custom configurations.

• Energy-efficient with double or triple glazing and thermal break frames.

• High-security features: multi-point locks, PAS 24, Secured by Design.

• Custom finishes: colours, hardware, and low thresholds for accessibility.

• Local expertise across Caerphilly, Cardiff, and South Wales homes.

Bifold doors are designed with multiple panels that fold back neatly, creating a wide opening to the garden or patio. Unlike traditional sliding or French doors, they maximise space and light.

• Indoor-outdoor living – perfect for summer entertaining in South Wales gardens.

• Uninterrupted views – slim frames and large glass panes.

• Flexibility – open a single door for everyday use or fold the whole set for full access.

• Year-round comfort – A+ glazing keeps homes warm in winter and cooler in summer.

Daimant installs bifold doors in both uPVC and aluminium:

• Aluminium Bifold Doors – Slim sightlines, durable powder-coated finishes, and excellent structural strength. Best for larger openings and modern designs.

• uPVC Bifold Doors – More affordable, low-maintenance, and available in a range of finishes, including woodgrain effects. Ideal for smaller openings or budget-friendly projects.

Both options include energy-efficient glazing and security features, ensuring style without compromising performance.

Large glass doors don’t have to mean high energy bills. Daimant installs:

• A+ double or triple glazing with argon-filled units.

• Thermal break technology in aluminium frames to reduce heat transfer.

• Weather-sealed systems to eliminate draughts and condensation.

According to the Energy Saving Trust, modern energy-rated glazing can cut heating costs by up to 25% compared to older single-glazed patio doors.

Bifold doors are designed with home security in mind. Features include:

• Multi-point locking mechanisms securing doors at multiple points.

• PAS 24 compliance, ensuring resistance against forced entry.

• Secured by Design accreditation, endorsed by UK police forces.

• Toughened or laminated safety glass for extra protection.

Example: In Caerphilly, a detached home installed a 5-panel aluminium bifold system with anti-lift tracks and PAS 24 locks, ensuring full security while maintaining an open-plan design.

Homeowners in South Wales can fully customise bifold doors:

• Panel Configurations – from 2-panel to 6-panel systems, depending on the opening size.

• Colours & Finishes – from anthracite grey and black for modern homes to woodgrain for traditional properties.

• Thresholds – standard or low threshold options for wheelchair accessibility.

• Glazing Choices – clear, frosted, or solar-control glass.

• Opening Styles – choose whether doors fold inward or outward.

This flexibility makes bifolds suitable for everything from Cardiff’s modern new-builds to rural South Wales cottages where garden views are prioritised.

Prices vary depending on size, material, and glazing:

• uPVC bifold doors: £2,500–£4,500 fitted.

• Aluminium bifold doors: £4,000–£8,000 depending on configuration.

While aluminium bifolds are more expensive, they are longer lasting, slimmer, and better for larger openings, making them the preferred choice for most homeowners in Cardiff and South Wales.

With proper installation and minimal maintenance:

• uPVC bifold doors last around 20–25 years.

• Aluminium bifold doors can last 30–40 years thanks to their structural strength and weather resistance.

Regular cleaning of tracks and seals ensures smooth operation for decades.
