What is the difference between UPVC and Composite Doors?

Understanding the differences between UPVC doors and Composite doors is crucial when choosing the right entry door for your home. Both type of doors has their unique advantages. The choice often comes down to individual needs, including considerations on security, thermal efficiency, design, durability, also price.

Door Material and Construction

The primary difference between UPVC doors and Composite lies in their material structure. A UPVC door is typically made from plastic (unplasticized polyvinyl chloride) and is lightweight. It is made of a single material that features an insulated core sealed within a durable UPVC frame. On the other hand, the Composite door is made from a combination of materials, including wood, PVC, insulating foam, and GRP (glass-reinforced plastic). These materials are pressed and glued together under high pressure. Therefore, creating a thick, robust door slab that is superior in strength and durability.

Door Durability and Security

Composite are also generally more robust than UPVC doors, offering better resistance to physical attacks. The combination of materials in Composite results in a thicker door, which can also include a solid core. This in all makes the composite more secure against forced entry. UPVC doors, while still secure, may not offer the same level of security due to their construction and material properties. However, they still do make good quality front and back doors.

Door Thermal Efficiency

Both Composite and UPVC doors offer excellent thermal efficiency. However, the layered structure of Composite doors, with their combination of insulating materials, generally provides better thermal performance. This means that Composite doors are more effective in keeping heat in during the winter. This works in reverse during the summer, potentially leading to energy savings.

Aesthetic and Design

Composite doors offer a wider variety of designs and door finishes. This including a wood grain effect that makes them almost indistinguishable from real timber doors. They can also be customised in a wide range of colours and finishes. UPVC doors also offer flexibility in design and colour. Though, the options are somewhat limited compared to Composite doors. The plastic look of the UPVC doors can be less appealing to those seeking a traditional or high-end appearance.

Door Cost

Generally, Composite doors are more expensive than UPVC doors. The advanced construction and the variety of materials used in Composite doors contribute to their higher price. However, many homeowners find the additional cost to be a worthwhile investment due to the door’s longevity, increased security, and thermal efficiency.


Choosing between a UPVC doors and Composite depends on your specific requirements. This includes budget, aesthetic preference, security needs, also insulation. While Composite doors offer superior strength, security, and thermal efficiency, UPVC doors are a cost-effective, durable, and low-maintenance option that can meet the needs of many homeowners.
