If you are considering large glazed doors for your home in South Devon, security is likely to be one of your biggest questions. With so much glass and slim aluminium framing, it is understandable to wonder whether bifold doors can really provide the protection you expect.
The good news is that modern aluminium bifold doors are designed with security in mind. Our Alumina aluminium bifold doors from Liniar feature secure locking mechanisms and reinforced frames, are tested to PAS 24 requirements and carry Secured by Design accreditation.
Does more glass mean less security?
The security of a bifold door depends on the complete door system rather than simply the amount of glass it contains.
Aluminium provides a strong and durable frame that will not warp, rot or rust over time. Our Alumina bifold doors are made from high-strength aluminium and combine this inherent strength with integrated security hardware. This makes them well suited to larger glazed openings where homeowners want plenty of natural light without overlooking security.
Slim sightlines do not mean that the frame has been designed without security in mind. The Alumina system has been engineered for larger openings, with its locking arrangement and reinforced construction designed to provide a high level of security. Whether you live in a traditional property, a new build or a modern extension, the right specification can help you find the best style for your home.
How do multi-point locking systems improve security?
The locking system is one of the most important parts of any external door. Rather than relying on a single locking point, the Alumina system uses multiple bi-directional locking points to help secure the door across its height.
The system also incorporates shootbolts that secure firmly into the track, built-in anti-lift features and anti-bump cylinders. These features work together to make the door more resistant to common methods of forced entry.
This means security is considered throughout the door rather than being concentrated around one lock. It is also an important consideration when comparing a large glazed opening with a conventional front door.
For homeowners comparing secure doors in South Devon, it is worth asking exactly what locking system is included with the doors you are considering. Working with skilled suppliers means you can ask questions about the specification and make an informed choice before your next project begins.

Are aluminium bifold doors tested for security?
Yes. The Alumina aluminium bifold system is tested to PAS 24 requirements and carries Secured by Design accreditation.
PAS 24 is a recognised security standard for doors and windows. Products are subjected to physical testing designed to assess their resistance to common methods of forced entry.
Secured by Design is the official police security initiative, with products assessed against recognised security standards.
These independent standards give homeowners useful proof when comparing products rather than having to rely solely on claims about how secure a door looks or feels. We can explain these features throughout the process, helping you feel that your home improvement project is in safe hands.
What about the glass?
The locking system and frame are only part of the overall security of a bifold door. The glazing specification also needs to be considered.
Toughened glass is designed to withstand greater impact than standard glass, while laminated glazing incorporates an interlayer that helps hold the glass together if it is broken. Both options can provide additional security benefits, depending on the specification selected for the property.
Our Alumina aluminium bifold doors are available with 28mm double glazing or 36mm and 40mm triple glazing, giving homeowners options when considering security alongside energy efficiency.
The large glazed areas are an important part of the appeal of bifold doors, but the complete door system is designed around these larger openings. The range of configurations available means we can help homeowners find an ideal solution for their property. When discussing your options with us, we can explain the available glazing specifications and help you choose an appropriate configuration for your home.
Are aluminium bifold doors a good choice for South Devon homes?
For homeowners across South Devon and the wider South West, security is only one consideration. Your doors also need to cope with everyday use, changing weather conditions and the demands of a large opening.
Our aluminium bifold doors feature thermally broken tracks at the top and bottom, while low U-values help to reduce heat loss. The inherent thermal efficiency of aluminium contributes to the excellent thermal performance of the system, which can be particularly valuable when replacing older doors or creating a new opening as part of an extension.
Aluminium is also durable, corrosion-resistant and requires relatively little maintenance. The long service life and durability of aluminium can make it a practical choice for homeowners considering the sustainability of these doors as part of a wider home improvement.
Alongside our bifold doors, we also supply aluminium windows and a range of other doors, allowing homeowners to consider their wider home improvement project at the same time.
We work with homeowners across Newton Abbot, Torbay, Teignmouth, Exeter and the South Hams, helping them choose doors that suit their property and how they use their space.

What should you check before choosing bifold doors?
If security is a priority, there are several questions worth asking before placing your order:
- What security standard does the door meet? Look for recognised standards such as PAS 24 where appropriate.
- What locking system is included? Ask about the number and type of locking points.
- What cylinder is used? Find out whether anti-bump or other security features are included.
- What glazing is available? Your installer should be able to explain the available options.
- Who is carrying out the installation? A high-quality product still needs to be correctly installed to perform as intended.
- How will the installation be managed? Ask about communication throughout the project and who will be responsible for each stage.
Frequent communication can make a real difference to the homeowner experience, particularly when replacing a large opening or coordinating other work. Choosing an installer that works to the highest standards and provides a high quality installation can help avoid much trouble later.
