Colour Palette

When the first composite doors hit the market, there was only a limited choice of colours but that’s no longer the case. Roundbrand composite doors are available in pre-pigmented Black, Blue, Green, Red or White. We also have pre-stained Gold Oak and Rose Wood grain effects for a charming wood finish that’s all but indistinguishable from real timber.

Our composite door colours are applied during the manufacturing process for a long-lasting, fade-resistant finish. You can rely on your new composite door not to scratch, chip or peel and it’ll retain its good looks for years to come.

Our composite doors are renowned for their strength and energy efficiency, but they’re also some of the most attractive on the market. We have multiple designs on offer, covering everything from traditional properties to the most up-to-date, modern homes. Whether you live in a rural cottage or a fashionable city apartment, we can create the perfect composite door for you.
The choices don’t end there. We have an exciting range of door accessories available, from pristine handles and letterplates to bespoke glazing for anyone who wishes to include a window. Our glass comes in several distinct designs and varying opacities, so you won’t sacrifice privacy for style.

No Euro-cylinder so…no bumping…no breaking or snapping…no plug extraction! Our composite door locking systems are from industry leaders ERA, whose pioneering lock technology can be relied on to keep homes safe. Their patented ‘Vectis’ cylinder-free, multi-point lock encompasses ERA’s traditional lever technology and combines with today’s need for modern locking systems.
These locks represent the most up-to-date home security measures and we’re incredibly proud to include them. They achieve full Secured By Design accreditation and meet the requirements of PAS 23 and PAS 24.

Find It Hard To Believe That The Frames Aren’t Actually Made Of Wood!

We’re incredibly proud of our woodgrain finishes. Wooden doors have a distinctive texture and a traditional charm that can be hard to replicate. But with our incredible woodgrain finishes, you’ll get a sophisticated composite door that is indistinguishable from real timber, but with none of the inherent problems with warping or water damage.

This is because composite doors have laminated outer skins that water can’t penetrate. No matter how often or how heavily the heavens open, the rain will wash off your new composite door and won’t seep in. This gives composite doors inherent resilience and long lifespans, so you can rely on them more than traditional doors.
