Manhattan Composite Doors
The Manhattan features five perfectly proportioned square glazing panels arranged down the centre of the door, making it an ideal choice for anyone seeking a modern, stylish entrance.
Cost, Delivery & Installation
Every Manhattan is made to measure, so your door is built around your home and your chosen design. The final price depends on your preferred style, glazing, hardware and installation requirements.
Start by designing your Manhattan in our free 3D Door Designer, then request a no-obligation quote from one of our Trusted Installers. They'll visit your home, take accurate measurements and provide a tailored quotation.
Once your order is confirmed, your Manhattan composite door is manufactured to your exact specification before being professionally installed. Most installations are completed in around four weeks, although lead times may vary depending on your installer.

Your questions, answered.
What makes a Rockdoor stronger than other composite doors?
Rockdoors add security most composite doors don't have — a 360° internally-reinforced aluminium frame, optional steel security mesh, steel keeps, a high-density core and S-Glaze bonded glazing. Foam-filled or timber-core doors can be forced through the sash or glass; a Rockdoor resists it.
What guarantee does it come with?
A 10-year guarantee as standard on performance, plus a 3mm bow guarantee. The 3-star diamond Sold Secure cylinder is backed by a £2,000 guarantee against snapping, bumping, drilling or picking.
What will it cost for my home?
Each door is made to order, so your price reflects the finish, glazing, hardware, size and fitting you choose. Personalise your door, then get a free, no-obligation quote from a Rockdoor Trusted Installer.
Can I paint or re-colour it?
No — the PVC-U skin is engineered to hold its colour for life, so painting isn't needed and would invalidate the guarantee. Choose from 14 built-in finishes instead.
How do I look after it?
Very little upkeep — an occasional wipe with warm soapy water keeps it like new. Avoid abrasive cleaners; stainless-steel hardware comes with its own care kit.
Is it energy efficient?
Yes. An insulating core, bonded S-Glaze and a weather-sealed reinforced frame make it a thermally efficient, industry-leading door that keeps heat in and draughts out.
Can I add a cat flap or alarm contacts?
Cat flaps should be factory-fitted with your order (precision CNC-cut) — retrofitting invalidates the guarantee. Self-adhesive alarm contacts are fine; screwing into the frame is not.
Where do I buy one and who fits it?
Rockdoor sells through the trade only. A Rockdoor can weigh up to 100kg, so it's supplied and fitted by trained, insured Trusted Installers. Personalise your door and we'll match you with your nearest one.
