Your front door plays an important role in protecting your home. It needs to withstand everyday use, changing weather conditions and potential attempts at forced entry, while still complementing the appearance of your property.
For homeowners across the South West, composite doors can offer a strong combination of security, durability and practical performance. Their combination of materials, multi-point locking systems and recognised security standards can provide a robust first line of defence.
At DNA Window Solutions, we supply and install composite doors for homes across Devon and Cornwall. Here’s what makes them a popular option for homeowners who are taking door security seriously.
What makes a composite door secure?
Unlike a door made from one material, a composite door uses a combination of materials to create a strong and durable construction.
Many composite doors feature a foam core or solid timber core, depending on the specific door system. This is combined with a durable outer skin to create a rigid door that can withstand everyday impacts and changing conditions.
The construction is designed to provide strong resistance to forced entry, although security varies between individual products, so the complete specification matters. The frame, locking system, hinges and glazing all contribute to the security of the finished door.

Which security features should you look for?
Several features can contribute to effective composite door security.
Multi-point locking systems
A multi-point locking system secures the door at several points around the frame rather than relying on a single locking point.
This helps distribute force across the door and frame, making it more difficult for potential intruders to force the door open at one location.
The quality and specification of the locking hardware are also important. At DNA Window Solutions, our team can talk you through the locking systems available and help you understand the level of security provided by the complete door specification.
Accredited security standards
Security standards give homeowners a useful way of judging how a door has performed in controlled security testing.
PAS 24 is a recognised UK standard for assessing the security performance of doors and windows. Products are subjected to simulated forced-entry attempts to assess whether they meet the required level of resistance.
Our composite door ranges include products tested to recognised security standards such as PAS 24.
Are composite doors more secure than other door types?
Composite doors can offer strong resistance to forced entry because their construction combines a robust core, durable outer materials and modern locking hardware. However, security varies between individual products, so the specification and testing of the complete door are important when comparing composite, uPVC and timber options.

Why does the South West climate matter?
Homes across Devon and Cornwall can experience persistent rainfall, strong winds and coastal exposure. Properties close to the coast can also be exposed to salty air, which can affect exterior materials and hardware over time.
A door that remains stable in these conditions is important for both weather performance and security. Warping or movement can affect how a door closes and how effectively its locking system engages with the frame.
Quality composite doors can offer excellent durability and are designed to cope with the demands of everyday exterior use. Their low-maintenance construction also means homeowners can enjoy the appearance of a new door without the same ongoing upkeep associated with some traditional timber products.
For coastal homes, it is still important to consider the specification of individual components, particularly handles, hinges and locking hardware.
Security does not mean compromising on style
Choosing a secure door does not mean you have to sacrifice the appearance of your home.
Composite door designs are available in a wide range of styles, colours and finishes. This makes them suitable for everything from traditional properties to more contemporary homes.
You can also choose different glazing and hardware options to create a door that suits the character of your property. Whether you are replacing a front door or looking for composite back doors, the right specification can combine practical security with the appearance you want.
What else can composite doors offer?
Security is an important consideration, but it is not the only reason homeowners choose composite doors.
A well-specified composite door can also provide:
- Energy efficiency through the combination of the door construction and glazing
- Excellent durability for everyday use
- Low maintenance compared with many traditional timber doors
- A wide range of styles to suit different properties
- Improved comfort by helping to reduce draughts and heat loss
These features make composite doors a practical option for homeowners looking to replace an older or underperforming entrance door.
