What is a composite door?
A composite front door is made from a combination of materials to enhance strength, durability, insulation, and security. Unlike traditional doors, composite doors blend different materials such as uPVC, timber, ABS, and insulating foam to create a high-performance product.

How a composite door is made:
- Reinforced frame. A reinforced uPVC frame forms the door’s structure.
- Core Structure. The core is made from solid timber, which provides strength. Combined with the strong uPVC frame, a composite door is incredibly difficult to breach.
- Inner and Outer Layers. The reinforced uPVC frame and timber core are then cloaked in a weather-resistant ABS outer skin.
- Finish. The exterior finish can be textured to mimic real wood grain or finished in a smooth coating.

Benefits of a composite door
Composite doors are not just about strength; they also offer exceptional thermal efficiency. This means you won’t have to crank up the heating during the colder months, which will help to reduce energy bills. In a world where energy efficiency is increasingly important, composite doors offer a substantial advantage.
They also require very little maintenance. Unlike traditional wooden doors that may need regular painting or varnishing, composite doors retain their appearance with minimal upkeep. A simple wipe-down now and then is all that’s required to keep them looking pristine.
Sound insulation is another area where composite doors excel. The dense materials used in their construction help prevent noise pollution, ensuring your home remains peaceful. Composite doors can significantly enhance your home’s comfort if you live in a busy neighbourhood.
Security is, of course, a top priority for any homeowner. Composite doors have advanced locking systems that offer extra protection against intruders. With features like PAS 24 multi-point locking mechanisms and 3-star barrels, you can rest easy knowing your home is safeguarded against unwanted visitors. Composite doors blend strength, security, and style.

Reinforced frames provide added strength, making it incredibly difficult for intruders to gain entry. The robust materials used to create composite doors, from the solid timber core to an ABS plastic shell, make them formidable barriers against unauthorised access.

Door styles and colour options
Selecting the perfect design for entrance doors is essential.
First and foremost, consider your property’s architectural style. A door that complements the overall look of your home can significantly enhance its aesthetic appeal. For instance, a traditional composite door might suit a Victorian-era house, while a contemporary door type could be better suited to a modern build. Would you like something that fits a rural property? How about a stable door design for back doors?
Colour is another important consideration. The colour of your door can either blend with your existing decor or stand out as a striking accent. Popular choices include classic hues like black and white and bold shades like red and blue. Many homeowners opt for pebble grey, which offers a modern, sophisticated look. If black, white, red, blue, or grey isn’t for you, we have 250 colours to choose from.
Glazing options can also influence your decision. Whether you want to enhance the aesthetics or improve functionality, various glass designs are available. For example, you might opt for decorative glass for added visual interest or clear glass for more natural light.
Seeking professional advice is essential when choosing a composite door design that complements your home, as your choice of door can alter its aesthetics. The Clearglaze team can offer insights and recommendations based on your personal preferences and your home’s unique characteristics.
Maintenance tips for composite doors
Composite doors are renowned for their low maintenance requirements, but a little care can go a long way.
Regular cleaning is a simple yet effective way to maintain your door’s appearance. A mild detergent and a soft cloth are usually all that’s needed to remove dirt and grime.
Occasional lubrication of the door’s hinges and locks is advisable to ensure smooth operation. This prevents squeaking and ensures that the door opens and closes effortlessly. A small amount of lubricant applied to the hinges and locks will aid durability and longevity.

Energy efficiency of composite doors
Many homeowners consider energy efficiency a significant consideration, and composite doors excel in this area. One key feature contributing to their thermal performance is the insulated core. This core helps to reduce heat loss, keeping the inside of your home warm in the winter and cool in the summer.
Energy-efficient glazing options are available for those seeking additional insulation. Double or triple glazing can significantly improve a door’s thermal performance, further reducing heat loss.
Beyond cost savings, enhanced energy efficiency contributes to a more sustainable home. By reducing your energy consumption, you’re also reducing your carbon footprint. This makes composite doors an eco-friendly choice for those who want to make their homes more environmentally responsible.
Summary
Composite doors combine style, security features, and energy efficiency. They are built to last and outperform a softwood door or hardwood door in every respect, providing peace of mind and adding value to your home.
With various styles and customisation options, there’s a composite door to suit every taste and property. The Clearglaze team will happily answer any questions.
