Choosing a new front or back door can be a big decision, from appearance, and insulation to security and durability. Two of the most popular options for homeowners are composite and uPVC doors. But what’s the real difference, and which is right for your home?
What is a uPVC Door?
uPVC (unplasticised polyvinyl chloride) doors are made from a single plastic material. Known for their affordability, low maintenance, and decent performance, they’ve been a go-to choice for decades. They offer a clean, modern look and are often used for both front and back doors.
What are Composite Doors?
Composite doors are made using a combination of materials, typically a solid timber core, glass-reinforced plastic (GRP), insulating foam, and a durable outer skin. This multi-layered construction gives composite doors enhanced strength, insulation, and security. They’re designed to look like traditional timber while offering modern performance benefits.
Key Differences Between Composite and uPVC
1. Security
- Composite doors are generally more secure than uPVC thanks to their solid core and robust build.
- Both door types can come with multi-point locking systems, but composite doors offer added strength and resistance against forced entry.
2. Insulation
- Composite offer superior thermal performance, helping to reduce energy bills and prevent draughts.
- uPVC are well insulated but may not provide the same level of heat retention as a composite option.
3. Appearance & Style
- uPVC tend to look more modern and are available in limited colours.
- Composite offers a wider range of styles, colours, and finishes, including woodgrain effects for a more traditional or premium appearance.
4. Durability & Maintenance
- Composite are resistant to warping, fading, and weather damage, making them highly durable.
- uPVC are also low maintenance but may show wear more quickly over time.
5. Cost
- uPVC doors are typically more affordable, making them a great budget option.
- Composite doors come at a higher initial cost but offer long-term value through better performance and durability.
Which One Should You Choose?
If you’re looking for a cost-effective solution with low maintenance, uPVC doors are a solid choice. But if you want the best in terms of security, insulation, and style, a composite door is the superior option.
