Composite vs UPVC Door: Which Is Best for Your Home?
Choosing a new front door for your house is a big decision, and many homeowners often struggle to pick between modern composite doors and classic uPVC doors. Both popular options offer great value, but they are built differently and offer unique benefits for your home. Understanding these differences helps you pick the right door for your home.
In this article, we will explain what composite doors and uPVC doors are. We will compare both in terms of durability, security features, energy efficiency, appearance, cost, and maintenance. By the end, you’ll be clearer about which door suits your home best.
What is a Composite Door?

A composite door is a modern front door made from different materials, including a timber core, foam, and a glass-reinforced plastic outer layer. These layers bond together under high pressure to create a thick layer, making it durable, secure, and weather-resistant. The outer layer often looks like real wood but needs far less maintenance and offers excellent insulation and long-lasting performance.
What is a uPVC Door?

A uPVC door uses unplasticised polyvinyl chloride, a strong type of plastic, for its frame and panels. The hollow chambers inside the frame trap air to keep your home warm and energy-efficient. These doors come in white, coloured, or woodgrain finishes to suit any home style. The plastic material resists rot, rust, and fading from sunlight. uPVC doors are lightweight, easy to maintain, and provide good insulation and security at an affordable price.
