Key Benefits of Composite Doors
Our composite doors are engineered using a combination of materials, typically including a solid timber core, glass-reinforced plastic (GRP) skin, and high-density polyurethane foam. This unique construction provides exceptional strength, ensuring that your doors are robust enough to withstand the test of time.
Unlike traditional timber doors, composite doors are resistant to warping, rotting, and fading, making them virtually maintenance free.
At D&M Windows, we understand the importance of security for your home and loved ones. Our composite doors are designed with cutting-edge security features, offering you peace of mind. The solid timber core provides excellent resistance against forced entry attempts, while the GRP skin adds an additional layer of protection. Moreover, our doors are fitted with multi-point locking systems, making them highly secure against potential intruders.
One of the standout advantages of composite doors is their exceptional insulation properties. Whether you choose a foam-filled or wood-filled composite door, both options provide excellent thermal efficiency. However, it’s essential to understand the key differences between the two.
Gone are the days of spending hours maintaining and painting your doors. Composite doors require minimal upkeep, saving you time and effort in the long run. The GRP skin is resistant to scratches, fading, and discolouration, ensuring that your door remains vibrant and attractive for years to come.

At D&M Windows, we truly understand and appreciate that each home is one-of-a-kind, where personal style holds great importance. This is precisely why our composite doors offer an extensive selection of colors, finishes, and designs, ensuring they align perfectly with your individual taste and effortlessly complement the aesthetics of your home. Whether you lean towards the timeless charm of traditional designs or embrace the sleek allure of contemporary styles, rest assured that we have the ideal door that will infuse your property with a touch of elegance.


We Offer Premium Wood Filled Composite Doors
Foam Filled or Wood Filled - What's The Difference?
On the other hand, wood filled composite doors offer additional benefits for those seeking maximum insulation. The timber core acts as a natural insulator, further enhancing the door's thermal efficiency. Wood filled doors also provide excellent soundproofing properties, minimising noise pollution from the outside environment. All of our Solidor range are wood filled premium composite doors.
In conclusion, when it comes to deciding between a foam-filled or wood-filled door, the choice often boils down to budget considerations. Opting for a wood-filled door is the premium option, offering the advantage of reduced maintenance requirements. It presents a challenging dilemma: should you invest more upfront for minimal maintenance over the next decade, or opt for a foam-filled door at a lower cost, potentially necessitating maintenance within the first 5 years of ownership?

Yes, composite doors are worth the extra cost for Derby homeowners. They last longer (30-35 years), provide better security with multi-point locks, and improve energy efficiency, potentially saving £100 annually on bills. Their premium, timber-like appearance also boosts curb appeal. While pricier than uPVC, their durability and low maintenance offer excellent long-term value.
Composite doors don’t always require special frames but are often paired with reinforced uPVC or aluminium frames for optimal performance and security. Standard frames can work if they’re sturdy and correctly sized, but our Derby fitters recommend composite-specific frames to ensure a perfect seal, enhance insulation, and match the door’s aesthetic, prolonging its lifespan in Derby’s varied climate.
A high-quality composite door typically lasts 30-35 years with minimal maintenance, outperforming uPVC (20-25 years) and timber (15-30 years with regular upkeep). In Derby’s weather, our composite doors are built to resist warping, fading, and wear, ensuring long-term durability. Choosing professional installation and occasional cleaning can maximise their lifespan.
While composite doors are highly durable, prolonged exposure to intense sunlight can cause minor issues like slight fading or thermal expansion, where the door may creak in extreme heat. However, our Derby-supplied composite doors feature advanced UV-resistant coatings and technologies like CoolSkin to minimise these effects, ensuring they maintain their colour and performance in the UK’s variable climate. Regular cleaning and choosing lighter colours can further protect your door from sun-related wear.
