Are composite doors draughty?2017-04-25T11:17:26+00:00

Composite doors should not be draughty. If you are experiencing draughts, make sure that your composite door is properly fitted and that the hinges have been adjusted correctly.

How do I care for my composite door?2017-04-25T11:17:31+00:00

Caring for your composite door is simple. To get the best from your composite door, it is important to oil the hinges and relevant hardware on a yearly basis. Apart from that, the only maintenance required is to wipe the surface of the composite door when it needs cleaning.

Can you get composite side panels?2017-04-25T11:17:36+00:00

Yes, we supply composite doors with matching composite side panels. These composite side panels can match the composite door in colour and glazing, or you can choose contrasting options.

Can composite doors be opened without a key?2017-10-09T14:50:42+00:00

We offer two different types of locking – composite doors which can be opened without a key if the deadbolt hasn’t been locked (the standard function for back doors) and composite doors which require a key to gain entry from the outside whether the deadbolt has been locked or not (the standard function for front doors – the door can be opened from the inside without a key unless the deadbolt has been locked). The options can be chosen under ‘Handle Type’ on our Composite Door Designer.

Can composite doors be painted?2017-04-25T11:18:17+00:00

Our composite doors feature a coloured skin. As the colour runs throughout the skin, rather than coating the surface, it does not wear away or fade like painted doors do. This makes the colour long-lasting and reduces the level of maintenance required to keep the door looking smart. All you need to do is clean the door with a sponge if it begins to look dirty.

Can composite doors be made to measure?2018-10-03T14:58:43+00:00

All of our composite doors are made to the measurements given to us by you. If you need help measuring your door, see our composite door measuring guide (pdf).

Why are composite doors considered to be better than other doors?2017-04-25T11:19:54+00:00

Composite doors are the latest addition to the door industry, and have been designed with the knowledge of the flaws of previous doors. Because of this knowledge and the freedom of using multiple materials, composite doors have been designed to phase out old flaws and create a whole new standard of door

Composite Doors – Phasing out common flaws

Unfortunately, many homeowners will experience flaws when it comes to their front or back door. The effects of seasonal heat changes are an unavoidable issue when it comes to doors made from a singular material. Reinforcing wood or uPVC doors can sometimes weaken the door, causing other issues. Another general issue is security – how can you keep your home secure without spending a small fortune on expensive additions? Without these additions, other doors are vulnerable to potential attacks. There are many other common flaws that people experience.

The design of composite doors has enabled these flaws to be taken in to consideration, and effectively phased out.

The GRP skin prevents the composite door from warping during seasonal changes, preventing the door from both sticking and causing draughts. The thermal core provides further energy efficiency benefits.

The GRP skin of composite doors is able to withstand a higher level of force than most other doors.

The GRP skin provides a maintenance-free finish. No sanding and painting is required to keep the door protected and looking fresh. It also won’t fade or discolour over time like other doors.

Composite doors have a longer lifespan than most doors, increasing the cost efficiency and reducing the environmental impact of the door.

If those benefits were not enough, The Composite Door Shop offers each composite door with a 10-year guarantee.

What is a composite door?2017-11-22T14:40:47+00:00

A composite door is an exterior door made from a multitude of materials, instead of a singular material such as wood or upvc, which have been chosen specifically for their beneficial properties.

There are three main types of door used in homes today. To answer the question in full, it is important to review each type of door.

Wooden Doors

Wooden doors are the earliest type of door used in homes and have varied in design and style over the years. Despite having been around the longest, the traditional appearance of wood remains highly desirable, especially over the plastic appearance of uPVC.

uPVC Doors

uPVC doors are more modern than wooden doors and are popular for several reasons. One of the main reasons is that uPVC doors are cheap in comparison to expensive wooden doors. They also have other benefits in comparison, such as they have a higher resistance to weathering and require less maintenance in general.

However, both of these doors have flaws which are very similar. The use of a singular material limits the design of the door significantly, allowing for certain flaws to be common across both types of door. This is where composite doors come in.

Composite Doors

Composite doors are the newest type of door used in homes. Composite doors have been designed taking into consideration the common flaws experienced in singular material doors. Using a combination of materials which have been selected for their beneficial properties, composite doors allow for the old flaws to be effectively ‘designed out’.

Composite door specification

Composite doors are made up from a variety of materials, including PVC, wood, insulating foam and GRP (glass reinforced plastic). The combination of materials result in a door that is very strong and secure.

Composite back and front doors have a high resistance to weathering and will not react to seasonal changes like a singular material door. Composite doors have a higher thermal resistance than wooden doors, due to the insulating foam core.

A composite door is designed to appear as a wooden door, with an attractive wood grain, but thanks to the materials used, it won’t fade, discolour or require any maintenance beyond wiping with a damp cloth if it gets dirty.

In short, composite doors are exceptionally well-designed modern doors made from several materials. Their superior quality sets a new high standard within the door industry.
