In an age where the distinction between inside and outside living becomes blurred thanks to modern architecture, spaciousness has become the new luxury. Today's architects and homeowners crave openness and light, with no sacrifice to comfort or function. From natural light to panoramic views and the ability to move seamlessly from one room to another, these are critical design elements that cannot be ignored when it comes to designing a modern home.
High-performance folding doors are revolutionising what is considered the 'spatial layout' in modern homes. They are unique with regard to their engineering and other attributes. So, what are these unique characteristics? And why are modern folding doors rapidly becoming the go-to solution for contemporary residential architectural design?
This blog discusses the science behind ‘spaciousness’ and provides insight into how modern folding doors create an elevated living experience, while providing insight into AluK’s BSF70 Folding Door System.
What Are Folding Doors?
Folding doors are a type of multi-panel door system that folds and stacks neatly to one or both sides of an opening, creating a wide, unobstructed passage between interior and exterior spaces. Unlike traditional doors that swing or slide, folding doors use a series of connected panels hinged together to open up entire walls with minimal visual interruption.
Key characteristics include:
- Multiple interconnected panels
- Smooth, synchronised movement
- Ability to stack compactly
- Wide opening spans that replace or enhance wall sections
The result? Walls become thresholds, and boundaries between spaces become seamless.
What Are BSF70 Folding Doors?
BSF70 Fold Doors are modern aluminium folding doors that stack and fold to the side, allowing you to have a full open wall and hundreds of ways to have a direct connection between your indoor and outdoor spaces. It is like many large pieces of glass that open and close like an accordion and let you have an unobstructed view when in the fully opened position.
The BSF70 is engineered with a 70 mm system depth and internally beaded aluminium profiles. It supports open-in and open-out configurations with flush threshold options, enabling flexible application across large openings. The system accommodates door leaf heights of up to 3500 mm, widths up to 1000 mm, and vent weights up to 130 kg. Heavy-duty stainless-steel rollers ensure smooth and consistent operation, while multi-point locking and security-rated hinges deliver enhanced performance and durability in high-traffic environments.
These doors may be very aesthetically pleasing, but they also have a high level of durability and security. Constructed with quality large-gauge aluminium, these doors offer a high-quality locking system and an extremely rigid mounting system with heavy-duty rollers that provide a smooth operation of even very large glass panels while feeling like they are very light on the track system.
How BSF70 Folding Doors Create Spaciousness
Spaciousness isn’t always about increasing square footage; it’s about how a space feels. BSF70 Folding Doors are designed to make homes feel bigger, brighter, and more open without changing the actual footprint.
Here’s how these doors create that sense of space:
1. Wide, Uninterrupted Openings
The BSF70 is designed to allow panels to fold and stack neatly to one or both sides of the opening, maximising clear opening width. With configurable layouts supporting multiple door leaves, the system enables large openings by efficiently stacking panels away from the aperture. This creates a strong visual and physical connection between internal and external spaces while maintaining smooth operation through heavy-duty rollers and precision-engineered hardware.
2. Smooth, Effortless Operation
The BSF70 Folding Door System uses four stainless steel wheels with heavy-duty roller options, engineered to support door leaves weighing up to 130 kg. This hardware configuration ensures consistent load distribution and smooth, controlled movement, even across large and frequently used openings.
3. Seamless Indoor-Outdoor Connection
The panels stack evenly, flush and square when they are wide open to provide a neat, tidy entrance. A clear view from inside to outside results in a seamless flow between your living space and outside surroundings, making them feel like one large area.
4. Flexible Opening Options
Choose between open in, open out, corner-opening or centre-opening to create the flow between the inside and outside of the home. This provides flexibility for designing your home to maximise moveable and open spaces.
5. Minimal Visual Obstruction
The BSF70 allows panels to fold and stack neatly to the side when fully open, clearing the aperture and minimising visual obstruction. Its flexible panel configurations give you control over how much of the opening is used at any time, whether partially or fully open, maintaining open views and a strong visual connection between indoor and outdoor spaces without disrupting the sense of openness.
In simple terms, BSF70 Folding Door creates a more expansive space by allowing more natural light inside and offering less visual obstruction through the flow between different areas of the building, therefore creating a barrier-free space inside of an open area; walls transform into comfortable, extending areas.
Design Flexibility for Modern Architecture
The BSF70 folding door system is crafted for modern home design and architecture focused on open spaces, clean lines, and light. Due to their 70 mm system depth, as well as being able to hold as many as 8 panels, each with a maximum height of 3 metres, the BSF70 system enables architects to create large, bright openings with minimal structural strength reduction.
The folding doors can be configured into a variety of openings, such as open-in, open-out, corner or centre opening, with multiple stacking options to one or both sides of the opening. Additionally, using colour and bead options, with a concealed bottom track will allow the system to integrate well into either a traditional or contemporary design.
Energy Efficiency & Sustainability Benefits
BSF70 Folding Doors support high-performance glazing, helping maintain indoor comfort while allowing abundant natural light into the space. Increased daylight reduces reliance on artificial lighting, while appropriate glass specifications help manage heat transfer for improved thermal performance.
Constructed from durable aluminium, the system offers long-term reliability with minimal maintenance. Aluminium is also recyclable, making BSF70 doors a sustainable choice for modern homes focused on longevity and reduced environmental impact.
