What Makes a Composite Door?
A composite door combines a solid timber core, a uPVC or GRP outer skin, and steel reinforcement, bonded together to create a door that outperforms traditional wooden or uPVC options on security, insulation, and longevity. They do not warp, rot, or require repainting, and they come in a wide range of styles and colours to suit any property.
Security Standards to Look For
Look for composite doors that meet the Secured by Design specification — the police-preferred standard. Key features include a multi-point locking system, anti-snap and anti-drill lock cylinder, and reinforced hinges. A quality composite door is among the most secure residential door options available in the UK.
Portsmouth is a port city on the south coast of England, the only city in the UK built on an island. It has a rich naval heritage — HMS Victory, Admiral Nelson's flagship at Trafalgar, is preserved in the Historic Dockyard alongside the Mary Rose museum and HMS Warrior. Portsmouth is home to a significant naval base. The Spinnaker Tower on the waterfront is a modern landmark offering panoramic views across the Solent.
Getting the Right Fit
Composite doors are made to order based on precise measurements. A professional installer will measure your existing opening carefully, advise on whether the frame needs replacing, and ensure the door is fitted to a standard that maintains its security and thermal performance. Always use an installer who visits your property to measure before providing a final price.
