Are composite front doors more energy efficient than uPVC front doors? | Exploring what makes a door energy efficient

John Collins - Managing Director

Author: John Collins - Managing Director

When it comes to enhancing the energy efficiency of your home, choosing the right front door is vital. The number of materials available can be overwhelming, so it is important to consider which material offers superior thermal performance.

In this guide, we delve into what makes composite front doors energy efficient and explore how they compare to uPVC front doors.

What makes composite front doors energy efficient?

Composite front doors are engineered from a blend of materials, including wood, uPVC, insulating foam, and glass reinforced plastic (GRP). This combination of materials often results in composite doors having excellent thermal properties. The solid core and insulating foam offer impressive U-values, making them an energy-efficient choice for homeowners. With the door sealed tightly to avoid gaps where draughts can enter, and heat can escape, your energy bills will be much lower.

Are uPVC front doors energy efficient?

uPVC front doors are mainly known for their affordability and may be the ideal option for you if your budget is slightly lower. Their U-values, however, often don’t match those of composite doors. uPVC doors are made from melted and cooled Unplasticised Polyvinyl Chloride (uPVC), whereas composite doors are made up of a number of materials bonded together, making them a more secure, thermally efficient and durable option. In uPVC doors, seals can also break down which may allow draughts in.

Is a composite door better than a wooden door?

All-round, composite doors offer better thermal efficiency, security, longevity and are much lower maintenance than wooden doors, all whilst providing an identical wood-grain effect that makes wooden doors so popular. However, wooden front doors still offer a range of benefits and are suitable if you have a slightly lower budget.
