Architrave

This moulding provides textural and visual appeal to doorways and windows by creating a frame around them.
This frame is not merely decorative, it also conceals the joint where the wall and door frame meet, as well as any subsequent cracks that may occur here as a result of movement between the two.
Architraves should be fitted before the skirting boards and doors are installed. Just be sure to get the wood carefully mitred so that the corners join together neatly for a polished look.
