Composite Doors in Belfast and across Northern Ireland

Modern Composite Doors for homes in Belfast and across Northern Ireland

Crafted using a variety of materials, there’s no doubt that composite doors have risen to prominence over the past few years. Composite doors in Belfast and Northern Ireland feature a remarkable insulating and secure foam core intelligently enclosed by a Glass Reinforced Plastic (GRP) skin.

This unique design makes the double glazed door resistant to warping, cracking, fading, and peeling, ensuring both our traditional and contemporary composite doors will look their best for many enjoyable years to come. It also makes them scratchproof and virtually maintenance-free.


Seriously secure

All our composite doors feature a precision-engineered locking system. The cylinder lock barrels are anti-bump, anti-pick, anti-drill, and anti-snap, making them almost impenetrable and can deter even the most resolute would-be intruders.

How does composite door security compare to other materials?

High-density foam core

In combination with numerous robust materials, our composite doors feature a 70mm high-density polyurethane foam core that keeps your home warm and insulates your home from external noise. Foam is a terrific insulator for two reasons. The first is the fact that foam is filled with gas bubbles. Gases are not as effective at conducting heat as either a liquid or a solid and trapping the gas in small bubbles stops the gas from transferring heat. The second reason is due to the polymer molecules making up the partitions of the bubbles which are connected loosely. This restricts the rate at which heat can be transferred from one molecule to another.

Reduce your carbon footprint

In addition to the thermally efficient foam core, our composite doors also use energy-efficient triple or double glazing low e-glass and are A-rated! These technologically advanced entrance door structures not only reduce your carbon footprint but can considerably save you money on your energy bills.

Design the ideal composite door for your Ireland home

As robust as the door design is, the colour finish is too and is designed to look good for years to come. With the sophisticated appearance of solid timber, you have the choice of a variety of colours. You can even pick different interior and exterior colours to match the inside and outside of the property.

As well as a wide range of colour choices and finishes to choose from, the glazing type and additional hardware (door handles, letterboxes, etc) are also fully customisable; allowing your own individual style to shine through every little bit of your home.

Are composite doors more expensive than uPVC?

Which is better a uPVC door or a composite door?

The choice between uPVC and composite doors will often depend on individual requirements. UPVC doors are cost-effective, require less maintenance and offer design flexibility, but they may fade and be more vulnerable to the elements. In contrast, composite doors are durable, resilient and maintain their appearance for a longer period.

They provide superior durability, insulation and security. Ultimately, factors such as a homeowner's budget, desired aesthetics and the need for long-lasting performance should be considered when deciding between the two options.

Do you need a new frame with a composite door?

For the installation of a composite door, it is advisable to replace the current door frame with a new one to ensure a proper fit and provide adequate support for the door's weight. This not only enhances security, durability and functionality but also ensures optimal performance.

Homeowners should seek guidance from door suppliers or professionals, such as Turkington Windows, to determine the specific requirements for their installation. By replacing the frame along with the door, a secure and precise fit can be achieved, offering peace of mind and optimal functionality for the composite door.
