When it comes to choosing a front door that combines style, durability, and security, many homeowners in the North West are turning to composite doors. But what is a composite door, and why is it becoming the preferred choice for so many?
At PH Composite Doors, with over 25 years of experience in the supply and installation of composite doors, we’ve seen firsthand the benefits these doors offer. In this comprehensive guide, we’ll explore everything you need to know about composite doors — from what they are and why you should consider one, to the benefits they bring to your home.
A composite door is constructed using multiple materials to create a product that combines the best characteristics of each. Unlike traditional wooden or timber doors or uPVC doors, composite doors typically consist of a filled composite of solid timber core or insulated foam core, layered with Glass Reinforced Plastic (GRP composite) or other hard-wearing finishes. These act as great front doors to maintain home insulation.
This multi-layered design means composite doors are highly durable, weather-resistant, low maintenance, and available in various finishes and colours to complement any home style.
In areas like Atherton, Leigh, Tyldesley, Wigan, and Westhoughton, the weather can be unpredictable. Composite doors are specially designed to withstand rain, wind, and cold temperatures without warping or fading, making them ideal for homes across the North West. Their performance is crucial to the door’s longevity, particularly with the enhanced core composite.
Additionally, more homeowners are prioritising energy efficiency and security — two areas where composite doors outperform traditional options.
Composite doors are built to last. Their filed composite solid internal structure resists warping, cracking, or splitting, while the GRP composite outer skin stands up to everyday wear and tear. This makes them perfect for busy households and high-traffic entrances.
Security is a top priority for many homeowners. Composite doors often feature advanced multipoint locking systems and a robust internal core in the door panels, making them significantly harder to break into than standard doors.
The insulation properties of composite doors help retain heat, reducing energy bills and keeping your home comfortable year-round. This makes them an excellent choice for eco-conscious families and anyone looking to reduce heating costs.
Unlike timber doors that require regular painting or varnishing, composite doors need minimal upkeep. A quick wipe with a damp cloth is usually enough to keep them looking brand new.
Composite doors come in a wide variety of colours, textures, and glazing options. Whether you want a classic woodgrain look or a modern smooth finish, there’s a composite door to suit every aesthetic.
Choosing the right front door is a vital part of securing and beautifying your home. Here are a few more reasons why composite doors are a smart investment:
Performance plays a critical role in determining the lifespan and reliability of a door, particularly in environments where durability and structural integrity are non-negotiable. From resisting daily wear and tear to withstanding environmental stressors such as humidity, temperature fluctuations on the panels, and impact, a door’s performance is central to its long-term function.
A key factor influencing performance is the advancement in core composite materials. Modern composite cores are engineered to provide superior strength, moisture resistance, and thermal stability—properties that directly contribute to minimizing warping, delamination, and surface degradation over time. As a result, high-performing doors maintain their fit, finish, and functionality far longer than traditional alternatives.
Moreover, consistent performance reduces the need for frequent maintenance and replacements, offering long-term cost savings and sustainability benefits. Whether used in residential, commercial, or industrial applications, doors that are built for performance ensure peace of mind, enduring quality, and lasting value.
To better understand the advantages, let’s break down the components:
This combination of materials ensures composite doors outperform wooden and uPVC alternatives in nearly every category.
A high-quality composite door needs professional fitting to maximise its security, insulation, and longevity. At PH Composite Doors, our experienced team offers precision supply and installation services across the North West.
Improper installation can lead to drafts, leaks, and operational issues. That’s why it’s essential to work with a provider who knows what they’re doing. We also specialise in composite door replacements for outdated or damaged entrances.
To keep your door in top shape:
These simple steps will help ensure your door remains functional and attractive for years.
Composite doors are valued not only for their strength and security but also for their adaptability across different building styles and functional requirements. This is due to the innovative combination of materials, typically including a solid timber core, reinforced frame and a durable GRP (glass-reinforced plastic) skin. As a result, composite doors offer a versatile solution that caters to a wide range of architectural needs.
Whether you’re working on a contemporary new build or restoring a period property, composite doors are available in a variety of styles, finishes and glazing options to complement your design. Beyond aesthetics, they also provide performance benefits suited to specific applications, such as improved thermal efficiency, advanced locking systems for security and weather resistance for exposed locations.
This range of customisable features makes composite doors an ideal choice for architects, homeowners and developers alike. Whatever the project type or environment, there is a composite door solution that balances visual appeal with high-performance functionality.
GRP, or Glass Reinforced Plastic, is a key component in the construction of composite doors and plays a vital role in their overall performance. Often used as the outer skin of the door, GRP is a durable, lightweight material made by reinforcing plastic with fine glass fibres. This combination gives it excellent strength, impact resistance and long-term stability.
One of the primary advantages of GRP is its ability to withstand harsh weather conditions without warping, cracking or fading. Unlike timber, it does not absorb moisture, making it ideal for front doors that are exposed to the elements. GRP also provides a smooth and attractive finish that can replicate the look of timber grain while offering far superior durability and minimal maintenance.
In addition to its resilience, GRP contributes to the energy efficiency of composite doors by helping to maintain a strong, insulated barrier. This supports improved thermal performance, reducing heat loss and helping to keep indoor spaces more comfortable year-round.
Overall, GRP is a critical factor in what makes composite doors so reliable. It enhances the door’s strength, longevity and visual appeal, making it a smart choice for homeowners seeking both performance and style.
