We offer an extensive range of composite door designs and colours, as well as PVC-U doors, French doors, and exit doors. Composite doors are becoming an increasingly popular choice due to their modern wood-effect appearance. They combine the look and feel of a timber door with a tough, durable outer skin with a high density foam core, which offers excellent thermal performance and low U values.
PVC-U doors are a practical, versatile and low-maintenance option for building projects of all sizes.
