As the name suggests, composite doors are manufactured using different materials such as wood, polyvinyl chloride(PVC) and glass-reinforced plastic (GRP). These are more energy efficient than UPVC doors due to their thickness. 

These are thermally efficient doors that can be used in any kind of environmental conditions. The PVC material provides insulation which is a much-desired characteristic of composite doors. Isolation lockout heat during the summer and also keeps the cold out during the winter. If you’re installing Solidor doors in your house, then you need to hire professional solidor fitters for composite doors

Composite doors reduce the need to cut down trees because wood is used together with other materials. Hence, these doors are environment- friendly as compared to wooden doors. 

These doors are more secure due to the glass-reinforced plastic (GRP) material. The door cannot be easily broken and therefore when you are away you can feel comfortable as no one can enter your house by breaking through these doors. 

Glass-reinforced plastic is used as the cover that provides a longer durability. Composite doors have no maintenance costs because they can be easily wiped off with a piece of cloth.

They are weather-resistant and last for more than 30 years if looked after properly. For UPVC doors, the life expectancy is slightly less at 20 to 25 years, but this also depends on how well you take care of it.
