Choosing the right door for your home is a crucial decision. It’s not just about aesthetics; it’s about security, durability, and energy efficiency. That’s where composite doors come in.

Composite doors are gaining popularity among homeowners for their superior performance and stunning appearance. But what exactly makes them stand out. In this blog post, we’ll explore why composite doors are an excellent choice for your home. Whether you’re renovating or building anew, discover why composite doors should be at the top of your list.

What is a Composite Door?

Composite doors can be made from a combination of materials, including wood, uPVC, aluminium and insulating foam. This multi-layered construction gives them superior strength, durability, and insulation compared to traditional single-material doors.

The outer layer on most composite doors is typically made from robust glass-reinforced plastic (GRP) or ABS plastic. These materials mimic the appearance of wood but require far less maintenance.

Composite doors provide a balanced solution that combines the strengths of wooden and uPVC doors while minimising their weaknesses. They offer the look of wood with the low maintenance of uPVC, all while providing superior security and insulation.

This makes them an excellent choice for any homeowner looking for a durable, stylish, and secure door. For more information on our composite door options, visit our Composite Doors page.

Security of Composite Doors

One of the standout features of composite doors is their exceptional security. Here’s why they offer superior protection for your home:

Robust Materials

Composite doors are constructed from a combination of strong materials, including wood, uPVC, and glass-reinforced plastic (GRP). This multi-layered design provides unparalleled strength and durability, making it difficult for intruders to break through.

Multi-Point Locking Systems

Unlike traditional doors that might have a single lock, composite doors come equipped with multi-point locking systems as standard. These locks secure the door at multiple points along the frame, ensuring a tight fit and making it much harder to force open.

Secured by Design

Many composite doors adhere to the “Secured by Design” standards, a police-backed initiative focusing on crime prevention through improved security measures. Doors that meet these standards have undergone rigorous testing to ensure they provide the highest level of protection.

Laminated Glass

Composite doors often feature laminated glass, which adds an extra layer of security. Laminated glass holds together when shattered, preventing easy access and reducing the risk of injury from broken glass.

3-Star Locks

High-quality composite doors are fitted with 3-star rated locks, the highest standard for security. These locks provide maximum protection against picking, drilling, and other common methods used by burglars. Learn more about the benefits of 3-star locks.

Steel Reinforced Outer Frames

The outer frames of composite doors are often reinforced with steel, adding another layer of security. This reinforcement ensures that the door remains solid and resistant to forced entry, even under significant pressure.

Durability, Longevity, and Maintenance of Composite Doors


Composite doors are renowned for their exceptional durability. They are designed to withstand harsh weather conditions, including heavy rain, strong winds, and extreme temperatures.

The combination of materials used in their construction ensures that composite doors are robust and long-lasting. Unlike traditional wooden doors, they do not warp, crack, or swell, maintaining their integrity over time.


One of the key benefits of composite doors is their impressive lifespan. These doors are built to last, often exceeding 20 years with proper care.

The high-quality materials and advanced manufacturing processes contribute to their longevity, making them a cost-effective investment for homeowners. Over the years, composite doors retain their appearance and functionality, offering consistent performance and security.

Low Maintenance

Composite doors are incredibly low maintenance compared to their wooden and uPVC counterparts.

Unlike wooden doors that require regular painting or staining to prevent rotting and maintain their appearance, composite doors have a durable outer layer that does not need such upkeep. This outer layer, often made of GRP, resists fading and discolouration, keeping the door looking fresh and new.

Composite doors are designed to be resistant to weathering. They do not absorb moisture, which means they won’t warp or swell in damp conditions. This makes them ideal for the UK’s variable climate.

Keeping a composite door clean is straightforward. A simple wipe down with a damp cloth is usually enough to remove dirt and grime, ensuring the door maintains its aesthetic appeal without extensive cleaning efforts.


Composite doors offer the perfect combination of durability, longevity, and low maintenance, making them an excellent choice for any homeowner. They provide long-term value and peace of mind, knowing that your door will stand the test of time with minimal upkeep.
