Everything You Need to Know About Composite Doors

Looking to upgrade your home with a composite door? If so, you’ve come to the right place. In recent years, they have become a highly popular choice for homeowners, thanks to their stylishly modern aesthetic, as well as a highly practical choice for homeowners looking to enhance the security and aesthetic appeal of their homes. From their durable construction to their energy efficiency qualities and customisation options, composite doors offer a range of great advantages that make them stand out in the market.

What are composite doors?

Composite doors are constructed from a blend of materials, each chosen for its specific properties and benefits. At the core of a composite door is a solid timber framework, providing stability and structure. This timber core is reinforced with layers of other materials, such as uPVC, steel, and glass-reinforced plastic (GRP).

The uPVC layer serves as a protective barrier, shielding the timber core from moisture, rot, and corrosion. This helps to ensure the door’s longevity and reduces the need for frequent maintenance. Steel reinforcements are strategically integrated into the door’s design to enhance its strength and security. This significantly increases the door’s resistance to impact and attempted intrusion, making it a robust barrier against break-ins.

On the exterior surface of the door, a layer of glass-reinforced plastic (GRP) is applied. GRP is renowned for its exceptional durability, making it ideal for reinforcing the door against warping, cracking, and fading caused by exposure to the elements.

What are the benefits of composite doors?


  • Durability: Composite doors are engineered to withstand the rigors of daily use and harsh weather conditions. The combination of timber, uPVC, steel, and glass-reinforced plastic (GRP), creates a sturdy and resilient door that is resistant to warping, rotting, and fading. This ensures that composite doors maintain their appearance and functionality for years to come, making them a long-lasting investment for your home.
  • Security: Security is a top priority for homeowners, and composite doors offer peace of mind. Many composite doors are equipped with multi-point locking systems, steel reinforcements, and toughened glass, making them highly resistant to forced entry.

  • Energy efficiency: Composite doors provide excellent thermal insulation, helping to keep your home warm in the winter and cool in the summer. The insulating properties of materials such as uPVC and insulating foam cores reduce heat loss through the door, resulting in lower energy bills and increased comfort for you and your family.

  • Low maintenance: Unlike traditional wooden doors that require regular painting and varnishing, composite doors are virtually maintenance-free. They are resistant to moisture, rot, and corrosion, and can be easily cleaned with soap and water. In time, you’ll save heaps of time – and money!

How long do composite doors last?


Composite doors are highly durable and long-lasting, especially when well maintained. On average, composite doors boast a lifespan of 30 years or more, making them a smart long-term investment for your home.

Can I paint a composite door?


While composite doors typically come with factory-applied finishes that require little to no maintenance, painting is an option for homeowners looking to customise their door’s appearance or refresh its look over time. However, it’s crucial to follow specific guidelines for optimal results.

Firstly, choose a high-quality -grade paint designed for use on composite materials. This will better adhere properly to the door’s surface and withstand outdoor elements without peeling or fading prematurely.

Before painting, thorough preparation is key. Start by cleaning the door thoroughly to remove any dirt, dust, or debris. Next, lightly sand the surface to create a rough texture that will help the paint adhere better. Be sure to wipe away any sanding residue before proceeding. Next, apply a primer specifically formulated for use on composite materials. This will help ensure proper adhesion and provide a smooth base for the paint. Allow each coat of paint to dry completely before applying the next, following the manufacturer’s recommended drying times.

After the final coat has dried, consider applying a clear sealant or topcoat to protect the paint against the elements.

Can composite doors be trimmed to fit my doorway?


However, this task requires specialised tools and expertise to achieve precise and clean cuts without compromising its strength or functionality. Any errors or improper trimming techniques can result in structural weaknesses or damage to the door, potentially voiding its warranty.
