Pros and Cons of Various Composite Door Materials

There are a lot of options on the market when it comes to choose the best door for your house. One popular choice is composite doors, which offer a blend of durability, security, and aesthetic appeal. Composite doors, installed by experienced installers of composite doors, are made from a combination of materials, including wood, uPVC, insulating foam, and glass-reinforced plastic (GRP). Together, these components produce a sturdy, weatherproof, and energy-efficient door. To assist you in making an informed choice for your home, we will examine the advantages and disadvantages of several composite door materials in this post.

1. Wood-Composite Doors

Wood-composite doors are made from a combination of wood fibres and resin to resemble traditional wooden doors in appearance. These doors offer several advantages, including excellent durability and resistance to warping, cracking, and rotting that can be associated with natural wood. They also provide enhanced insulation properties, contributing to improved energy efficiency in your home. Additionally, wood-composite doors can be customized with a variety of finishes and styles to match your aesthetic preferences. Let's explore the pros and cons:
  • Aesthetics: Wood-composite doors provide the warm, natural look of wood, allowing you to maintain a traditional or classic style for your home.
  • Insulation: The combination of wood fibers and resin provides excellent thermal insulation, helping to keep your home comfortable and reduce energy consumption.
  • Durability: Wood-composite doors are designed to be resistant to warping, rotting, and cracking, making them a long-lasting option.
  • Maintenance: While wood-composite doors are more resistant to weather conditions compared to solid wood doors, they still require periodic maintenance to protect them from moisture and sunlight damage.
  • Cost: Wood-composite doors tend to be more expensive than other composite door materials, mainly due to the higher cost of the wood fibers. However, this additional cost can be justified by the premium aesthetic appeal and the authentic wood-like appearance.

2. uPVC-Composite Doors

uPVC-composite doors are made by combining uPVC (unplasticized polyvinyl chloride) and a composite material. These doors have gained popularity due to their affordability and low maintenance requirements. The uPVC component provides durability, as it is resistant to moisture, rotting, and fading, making these doors a long-lasting option for your home. Additionally, uPVC-composite doors offer excellent thermal insulation, helping to keep your home comfortable and energy-efficient. Let's delve to the pros and cons:
  • Cost-effective: uPVC-composite doors are generally more affordable compared to other composite door materials, making them an excellent option for homeowners on a budget.
  • Low maintenance: These doors are highly resistant to weathering, fading, and rusting, requiring minimal maintenance over their lifespan. This low-maintenance characteristic makes wood-composite doors a convenient choice for homeowners who want a durable and long-lasting.
  • Insulation: uPVC-composite doors offer good thermal insulation, contributing to improved energy efficiency. The combination of uPVC and composite materials in these doors helps to minimize heat transfer, reducing energy loss and enhancing the overall insulation of your home.
  • Limited color options: uPVC-composite doors often have a limited range of color options, which may not suit everyone's aesthetic preferences.
  • Potential brittleness: uPVC can be prone to becoming brittle over time, especially when exposed to extreme weather conditions.

3. GRP-Composite Doors

GRP-composite doors, also known as fiberglass doors, are made from glass-reinforced plastic. This composite material is lightweight, durable, and provides excellent security. The fiberglass component offers exceptional strength, making these doors resistant to impacts and break-ins. Furthermore, GRP-composite doors are highly resistant to weather conditions, such as extreme temperatures and moisture, ensuring their long-term performance and minimal maintenance requirements. Let's examine the pros and cons:
  • Strength and security: GRP-composite doors are exceptionally strong and resistant to impact, making them an ideal choice for security-conscious homeowners.
  • Low maintenance: These doors require minimal maintenance and are resistant to warping, rotting, and rusting.
  • Versatility: GRP-composite doors are available in a wide range of colors, finishes, and styles, allowing for greater customization to match your home's aesthetic.
  • Cost: Fiberglass doors tend to be more expensive than other composite door options due to the manufacturing process and materials used. The meticulous manufacturing process and the high-quality fiberglass material contribute to the higher cost.
  • Limited insulation: While GRP-composite doors offer some insulation benefits, they may not provide the same level of thermal efficiency as other composite materials. The glass-reinforced plastic (GRP) used in these doors may have lower insulation properties compared to materials like uPVC or wood.
Composite doors are an excellent choice for homeowners seeking a balance of durability, security, and aesthetics. Each composite material used in the manufacturing process has its own set of advantages and disadvantages. Wood-composite doors provide a classic look but require periodic maintenance, uPVC-composite doors offer affordability and low maintenance but may have limited color options, and GRP-composite doors are strong and versatile but can be more costly.


In conclusion, the benefits of composite doors make them a compelling choice for homeowners. Their striking aesthetics, robustness, thermal efficiency, security features, noise reduction, low maintenance, customisability, and longevity make them a superior door solution. While the initial cost may be higher, the long-term benefits and value they provide make them a worthwhile investment for any home.
