Demand is growing for larger glazed openings in modern residential design, alongside an increasing importance of connecting internal and external spaces.
Developers and specifiers are more often required to balance natural light with access to outdoor areas, thermal performance and contemporary aesthetics. Aluminium door systems help strike this balance. They remain a popular specification choice across housing developments, refurbishment projects and residential extensions.
Selecting the right kind of aluminium door is an important decision and should be based on the requirements of each project.

Why External Access Remains a Key Design Consideration
Modern residential design continues to prioritise open-plan living, indoor-outdoor connection and increased natural light. External door systems are important as they can connect living spaces to gardens and patios, maximise glazed areas and support modern aesthetics.
Different projects may require different door configurations depending on available opening space, the property type, design intent and the expectations of the home occupier.
Bifold, Sliding or Heritage Doors: Which System is Right for Your Project?
System selection should be based on project requirements rather than just aesthetics. BDC Aluminium supplies three different aluminium door systems.
Bifold Doors
Bifold doors are suitable for creating wide openings. Their panels fold neatly to one side and are popular for housing developments, rear extensions and garden-facing elevations.
We supply both Smart Visofold 1000 Slim and Visofold 6000 Bifolds. They allow a strong connection between indoor and outdoor spaces and are ideal where maximum opening width is a priority.

Sliding Doors
Sliding doors operate along a track, making them well-suited to projects where maximising glazed areas and preserving usable floor space are priorities. They’re suitable for large glazed areas and are popular within contemporary housing developments, luxury residential projects and apartment schemes.
Our Visoglide Plus system is an ideal choice when uninterrupted glazing is a key objective.

Heritage Doors
Last but not least, Heritage doors – a classic option with modern performance. They’re best suited to period refurbishments, heritage-inspired developments and character properties.

The Smart Heritage Door helps to achieve a balance between aesthetics and practical performance.
