Design & Order Composite Slate Grey Doors Online, Either Fully Installed or Supply-Only

In recent years, grey has enjoyed a surge in popularity in interior and exterior design. This popularity is reflected by the sheer depth of shades of grey across all our composite doors.

Slate grey is a remarkably modern, fairly light shade of grey. Slate grey composite doors can provide the perfect focal point for new and older properties.

Slate Grey Composite Doors – The Go-To For Modern Cool

At first glance, slate grey appears to be a strictly modern colour. However, when installed alongside red brick or stone, you’ll find those natural tones draw out its natural earthiness, making it a perfect complement for older properties.

It works surprisingly well as an external door colour for cottages and Victorian homes.

Conversely, when paired with sleeker, modern exteriors of contemporary properties, a slate grey composite door’s blue notes will be accentuated and change the look of the colour completely.

This is why we encourage all our customers to take their time when looking through our selection of composite door colours. Slate grey is a perfect example of the depth of variety this range of shades can deliver depending on its surroundings.

Personalising your Slate Grey Composite Door

Once you’ve selected slate grey for your new door, it’s time to choose your style and other features.

You can select from over ten different door frame designs, finding one that will truly make your new door colour choice pop.

You can also choose from a series of door handles and various shades of metal. We allow this same freedom of choice with a range of door knockers.

Our traditional and standard ranges offer classic and contemporary styles, so you can design your door to fit your property perfectly.

Our Coastal BLU range offers the utmost durability, made with marine-grade stainless steel to provide both style and an extensive lifespan.

If you go for a style with inset windows, you can choose from seven styles of glass, and for extra impact, you can select from over fifteen different kinds of side panels to complement your door frame.

What Are The Benefits of Composite Doors?

Homeowners can enjoy increased versatility with Value Doors’ grey composite doors, as they come in a wide range of styles and designs. The front composite door provides enhanced security, ensuring that your home is well-protected.

These doors are made using durable and robust materials, including glass-reinforced plastic and a laminated pine core, which not only offer security but also an attractive appearance. They create an elegant and reliable entrance to your home, providing a sense of security and peace of mind.

Moreover, the composite door’s core is constructed with tightly packed materials, such as a foam casing, which is highly efficient at retaining heat within the home. This energy-efficient feature can help reduce heating costs, making the doors a cost-effective and practical option for homeowners.
