What is a composite door?

At Cliffside, our composite front doors contain a foam-filled core, making them incredibly strong as well as improving their insulation capabilities, for both sound and heat. The outer core is made up of a moulded glass-reinforced plastic (GRP) skin, giving it impressive weather resistance as well as an attractive appearance. They are highly customisable and able to be installed with a range of decorative glass options, hardware options such as letter plates, and a variety of colours.

What are the benefits of a composite door?


Composite doors are incredibly durable and weather resistant, meaning they won’t rot or warp. This is largely thanks to their construction, with the GRP skin found on the outer layer specifically in place to ensure the elements have no impact on the appearance and performance of your door.

Noise Reduction

Whilst the outer shell of the door works as a durable coating, the inner core helps to reduce external noise from entering your home. This creates a quieter and more peaceful environment, especially if you live on a main road. At Cliffside, our composite doors are installed with double glazing as standard, which also helps to reduce sound transfer.


Our composite doors are available in a huge range of colours, finishes, and glazing options/glass designs. If you’d like something more natural, we’re proud to offer a lifelike woodgrain finish, but more contemporary, minimalist options are available too. After all, an impressive door style is a great way to leave a lasting impression.

Low Maintenance

A common frustration with traditional timber, or ‘wooden doors’ is that they regularly require timely and costly maintenance, such as painting and varnishing. With composite doors, an occasional wipe-down with a damp cloth is all you need to do to keep your entrance door looking its best.


At Cliffside our dream composite doors are incredibly secure, boasting an incredible width of 44mm – almost double the thickness of a standard uPVC door. They also feature multi-point locking mechanisms, giving you complete peace of mind that you and your family are kept safe all year round.

Thermal Efficiency

Another crucial factor is its thermal efficiency. Composite doors from Cliffside have an insulated core, helping to trap heat in the winter but keep it cool in the summer. In turn, this excellent thermal performance can lead to lower energy bills.

What is the average lifespan of a composite door?

Composite doors are very much a long-lasting addition to your Lincolnshire home. With an average lifespan of 30 years, this can easily be surpassed if the door is taken care of properly. It’s best to view a new front door as a long-term investment rather than an initial purchase, as they can also add to the value of your home.
