Composite vs uPVC door: which is worth it?
A uPVC door is the cheaper choice, usually a few hundred pounds less than a composite door of the same size. A composite door costs more because it is thicker, more secure and better insulated, with a tougher finish that holds its colour for longer. uPVC suits a budget back or side door; composite is the one most people choose for a main front door, where the security and insulation earn their keep.

Common questions
For a main front door, most people find it is. A composite door is thicker, more secure and better insulated, and it holds its finish longer, which matters on the door you use and see most. For a back or side door that gets less weather and use, a cheaper uPVC door is usually fine.
A composite door generally lasts longer and keeps its appearance better, because the solid core resists warping and the coloured skin does not fade like uPVC can. Both will last many years if fitted well, but composite is the more durable of the two, which is part of what you pay extra for.
