What are Bi-fold Doors?

Bi-fold doors are made up of multiple panels that fold neatly together concertina-style when opened, creating a wide, uninterrupted space between your indoor and outdoor living area, taking open-plan to the next level.

These panels are connected by hinges, and slide along a track at the top and/or bottom of the frame, with homeowners often given the choice of whether the doors fold internally or externally.

Bi-fold doors are predominantly made using aluminium, an effective material thanks to its incredible strength and slim sightlines, meaning that when the door sets are closed, you can enjoy unobstructed views of your outdoor area.

The Magic of Indoor-Outdoor Living

One of the key reasons homeowners choose bi-fold doors is the seamless connection they offer between indoor and outdoor spaces. Here’s how they improve your home:

Increased Entertainment Space

Bi-fold doors open up your home to your garden, creating a larger, more flexible space for entertaining. Whether you’re hosting a family barbecue or just enjoying a quiet evening outdoors, these doors expand your living area. You can watch the children play outside from the comforts of your sofa, or enjoy breakfast whilst sampling the sounds of nature.

Maximising Natural Light

Bi-fold doors are, for the most part, glass doors that let in plenty of natural light when shut. This brightens up your home, reducing the need for artificial lighting and helping you save on energy bills. Regular exposure to natural light is proven to have several mental and physical benefits, including improved sleep, lower blood pressure, increased vitamin D production, and even leading to better mood and increased productivity.

Uninterrupted Views

Thanks to their sleek design and minimal framing, bi-fold doors offer unobstructed views of your garden or outdoor area. They turn your outdoor space into a focal point, allowing you to enjoy nature from the comfort of your home.

Increased Property Value

Bi-fold doors are a highly desirable feature for potential buyers. Their modern, stylish appearance and practical benefits add significant value to your home, especially when installed with top-quality materials and craftsmanship.

Beyond the Aesthetics: Practical Benefits

Bi-fold doors are not only visually stunning but also offer a range of practical benefits for homeowners:

Versatility

Bi-fold doors are incredibly versatile. Whether you’re looking for external bifold doors to connect your living room to the garden or internal bifold doors to divide rooms inside, these doors can be configured to suit your needs. We give homeowners the choice as to whether they’d like the doors to fold internally or externally, as well as factors such as door placement.

Security

When it comes to security, bi-fold doors are built to keep your home safe. Our doors feature advanced multi-point locking systems and are PAS24 compliant, ensuring your home stays secure while still offering a sleek design. Incredibly strong safety glass is utilised to give you peace of mind that your new doors will stand up to any potential intruders.

Energy Efficiency

Bi-fold doors are designed with thermal efficiency in mind. They help prevent heat loss and improve energy efficiency by featuring thermal break technology. This keeps your home warmer in winter and reduces heating costs. The glass effectively controls unwanted glare, so you also won’t need to worry about excessive heat or sunlight in the summer months.

Customisation

At Sandymount, we offer a wide range of customisation options for your bi-fold doors. From colours like anthracite grey and natural oak to hardware choices such as black or silver handles, you can tailor your doors to match your property’s décor.
