Composite doors are made up of a variety of materials, each chosen for the benefits they bring to the structure and performance of the door.

The inner core of a Bowater Door is polyurethane foam to offer high levels of insulation. The outer surface of the door is a GRP (glass-reinforced plastic) skin which is lightweight and extremely durable.

The supporting structure of the door depends on what model you choose. Single rebate doors feature an LVL timber and PVC structure to provide rigidity.

Premium double rebate doors use steel reinforcement in the frame as well as the door slab for additional strength and durability.

Bowater Doors are extremely secure,  low maintenance and stylish. All the materials used to construct your door have been carefully selected to ensure they continue to look and work as good as the day they were installed for many years to come.

In order to keep your door in excellent condition, we recommend this quick and easy maintenance routine.

To keep your door looking great

  1. Wash your door, frame and glass occasionally with warm soapy water
  2. Be gentle on protective finishes. A number of the components in your door are protected with a special lacquer coating Never use metal polishes, abrasive cleaners, chemicals or other cleaning solvents on your door, as these can damage the coating
  3. Don’t forget your threshold. This space at the base of your door frame can easily collect dust and debris. It should be cleaned regularly.

Annual maintenance

Lubricate all moving mechanisms with a light oil after installation and at least once a year.


By engaging the multi-point lock each time your door is closed, the door compresses tightly and evenly against the frame beading. This will deliver the following benefits

  1. It keeps your door in perfect alignment
  2. Engaging the lock will create a seal to eliminate drafts and improve the energy efficiency of your door and help cut your energy bills
  3. A tight fit will prevent the door from bowing due to natural expansion as a result of temperature fluctuations

We don’t recommend painting a composite door yourself. Bowater Doors have a tough and durable GRP (Glass Reinforced Polyester) outer skin that won’t fade, warp or crack, so there is no need to paint after installation.

If you are looking to change the colour of your front door why not experiment with our online door designer? Thanks to a specialist in-house paint facility, we have the ability to paint these GRP skins to almost any RAL colour, from rural antique pink to cobalt blue, we have the range and the capability,  so you have the choice.

Experiment with colour

Please be aware, if you do decide to paint your own door,  your warranty does not cover any damage caused to the door or its finish.

Bowater Doors don’t recommend fitting a cat flap into your door yourself as this will invalidate your warranty.  Additional openings in your door will reduce its energy efficiency as there are more avenues for heat to escape.

If you require a cat flap in your new front door please discuss this with your retailer.

Although It’s possible to install a composite door that opens outwards, it’s commonplace for a front or back door on a house to open inwards in the UK for many reasons.


Exterior doors that swing outwards are awkward to operate, a pull motion is required instead of a push movement, so opening the door can feel clumsy, especially when carrying items like bags of shopping. From a safety point of view will always create a blind spot that could be hazardous for passers-by. In addition to this, external doors that open outwards are susceptible to gusts of wind that may cause injury to anyone near the door as well as damage the door.


Doors that open outwards require the hinges to be located on the external face of the door which can leave them exposed and vulnerable to intruders. For those who require installation of an outward opening door, Bowater Doors supply all doors with a fixed pin hinge that is inaccessible, so the door cannot be removed by the hinges from the outside.


Elements of the door that add additional protection for the homeowner such as a door chain cannot be fitted to doors that open outwards. From a functional point of view, if someone tries to gain access to your property when you answer the door, it is easier to push it closed as opposed to pulling.


The UK weather is renowned for being unpredictable and can often catch us all off guard. As well as the dangers posed by gusts of wind, snowdrifts piling up against the exterior face of the door will make it difficult to open.

Common applications for doors that open outwards

Outward opening doors are often used for side hinged garage doors where frequent access is required. This eliminates the need to open the main garage door every time access is needed. Residential garages often have cars in them or are used for storage so space is often limited. Outward opening side doors eliminate the need for the space for the door to swing. Additional restrictors can be added to the door to protect it in windy conditions.
