    Chamfered or sculptured frames

    Solidor composite doors are available with chamfered or sculptured frames. Chamfered composite doors have a cleaner, straighter finish which creates a stylish understated appearance. Sculptured composite doors, on the other hand, have a more decorative finish which looks great on properties with more traditional architectural features. Both chamfered and sculptured Solidor composite door frames provide the same high standards of performance and will complement all types of properties.

    Unique solid timber core

    Solidor composite doors feature a 48mm thick solid timber core. This is 10% thicker than most other composite doors, helping to massively improve thermal performance and boost security standards. The solid timber core is also extremely durable. It will enable the door to last for decades without any deterioration in quality. The timber used in a Solidor composite door is 100% sustainably sourced. FSC (Forest Stewardship Council) certified, the timber core consists of Falcatta and Meranti tropical hardwoods which are carefully selected for their outstanding performance characteristics.
