What Are Composite Doors?

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

However, what makes the composite doors manufactured by The Lockwood Window Company so unique is that they have combined the Solidor solid timber core and thermo plastic door skins, with the Kommerling galvanised steel reinforced profiles and Astral S locking mechanism, as they felt that this combination was even more secure than the standard Solidor range.

The company are able to do this as they manufacture each door on site themselves. Because of this unique combination, the composite exterior doors manufactured by The Lockwood Window Company are probably the most secure on the market. They are also resistant to weathering and will not react to seasonal changes like a singular material door.

Composite doors are also more energy efficient because they have a higher thermal resistance than wooden doors.

Although it appears to look just like a solid timber door, a composite door has greater benefits as, thanks to the materials used, it won't fade, discolour or require any maintenance beyond wiping with a damp cloth if it gets dirty.

Below is a comparison between a composite door made by us, and a typical foam filled door to give you an idea of the differences between the two. A key point is that our composite doors feature the steel reinforced profile unlike many other companies who just use thermal inserts which are not as strong.
