Composite Doors

The most popular replacement for timber doors is composite doors. These doors offer the widest choice for style whether you want to emulate the traditional look of wood, create a wow factor or want something simple and functional, you will find a door you will love.

The core of composite front doors is made of wood and insulating materials protected by other layers with an outer layer made of weather-resistant material. The different materials are glued together under high pressure. Composite doors are usually thicker compared to other types of doors.

Because they are made from a combination of materials, composite doors are extremely durable, strong and great looking.

GRP Doors

GRP stands for Glass Reinforced Polyester and is more commonly known as fibreglass. This is the waterproof outer layer of the door. The inside is made of a combination of timber and man-made materials depending on the range. GRP doors are also composite doors, being made of a mixture of materials.

GRP is light, requires very little maintenance, and can be manufactured in a variety of attractive colours and textures. GRP doors have high resistance to denting, warping, bowing, twisting, splitting, peeling, flaking, cracking and fading, making them extremely durable.

Aluminium Front Doors

In recent years an aluminium door has become the go-to choice for architects who want the ‘wow’ factor when designing homes for their clients. Typically thought of as sleek with their chic battleship greys or deeper charcoal colours, aluminium doors actually have more diversity in choice and can suit a wide range of homes. Balancing strength with weight, aluminium doors are tougher and more robust than other kinds of front doors and provide greater security and protection. Your door can also include security locking systems just like any other front door, firmly securing the door in place for extra peace of mind.

Choosing a Front Door

Your choice will mostly depend on the style of your home, your personal taste and your budget. Sometimes there are other factors that will influence your choice. Is your door more exposed to the elements? Are you positioned in a location that will require extra security? Do you need a cat flap? Do you want to match the colour of your garage? We will help you to consider all of the factors and make the right choice.

There is no pressure or obligation when you speak to us. Your home improvement purchase is important. We’re told that we have the best showroom in Cardiff and South Wales. Pop along to our Cardiff showroom, or call to arrange for us to visit you.

Patio Doors

When you want to maximise your view of the outside and benefit from more natural light within your home, patio doors make the ideal solution for Welsh homes. If you are building an extension or a new home, you will be able to plan your build around your choice. If you are replacing old doors or a window, your choice of patio doors may be led by the space you already have. Choose from French doors, sliding doors or bi-fold doors depending on how much space you want to fill and the way that you want them to operate. Read more about patio door options.

Bi-fold Doors in Aluminium or uPVC

Aluminium bi-fold doors are the ideal way to open up your home and bring the outside in, whilst still keeping the weather out. Our range of aluminium sliding and folding doors deliver outstanding reliability, performance and design every time. Our range of bi-fold doors enables you to expand your living space by opening up wide expanses of your external walls to create a seamless transition to the outside. Read more about bi-fold doors.

Sliding Patio Doors

Sliding patio doors provide lots of natural light with less frame to interrupt the view. They can fit into an existing space or you can expand your opening to fit across the whole wall. You can create a glass wall of up to a massive 13 metres. The benefit of sliding patio doors is that they sit in the track and you do not need to allow space for opening the doors.

French Doors

French doors are ideal for a wide range of uses, particularly when you want to maintain a traditional feel. Beautifully suited to open up into conservatories or to make a unique design statement within your home.
