    High-quality composite doors for homes in Kent and the South East

    Composite doors are arguably the highest performing doors available today. The combination of uPVC and composite materials used in their construction creates a door which is exceptionally strong, thermally efficient, and aesthetically attractive. Finished in a GRP skin that imitates the texture of timber, it also eliminates any maintenance requirements. Its durability makes composite doors highly weather-resistant, so it’s the ideal replacement solution for homes in exposed locations, like on the coast or in the countryside.

    Our collection of composite doors are available in over 30 styles and can be created in over 250 colour combinations inside and out . From contemporary designs to replications of traditional doors, they can be used in modern and period properties alike. Upgrading to a composite door is a sure way to add value to your property.

      Benefiting from streamlined manufacturing, composite is an extremely flexible material that can be uniquely tailored in a plethora of styles and colours, including popular Chartwell green, anthracite grey and sleek black. Agate grey composite doors have emerged in popularity, as their classic yet sleek appearance can beautifully complement any style of home. If you reside in a historic property, or you’re looking to inject a classical character to your home, wood effect GRP skins are also available. They replicate the look of real timber, so you won’t be able to tell it apart from an original wooden door.

      Our range of composite front and back doors can also be fabricated in dual colour designs, meaning that the outside and inside colour are different. This is a sure way to ensure your replacement door will seamlessly blend with your home’s existing appearance.

It will let natural light brighten your home, whilst retaining your privacy.

      Combine the timber style with the modern composite performance

      Composite doors combine the high performance of modern uPVC with the traditional look of timber. The GRP outer skin is scratch-resistant and protects the door frame and core from harsh weathers. So, unlike older wooden doors, it won’t rot, chip or warp. This skin protects the door’s materials, meaning they boast a lifespan of at least 30 years. Our composite doors also feature a 48mm premium cross-laminated solid timber core that is stronger than the average composite door for maximum security.

      You’ll benefit from the natural grain effect of timber but avoid any maintenance requirements. All composite doors need is the occasional wipe down with a damp cloth to remove any dirt. It means that composite doors continue to perform like new for many years, making them a great investment for your home.
