Surrounds & architraves

External window architraves & mouldings

Exterior window surrounds and external architraves frame the head and sides of an opening, adding depth and a more deliberate architectural outline. The phrase window external architrave describes the same trim-around-an-opening role in a different word order. See square profile moulding.

Kayvic’s lightweight, weatherproof profiles give the look of traditional cement mouldings while being practical to handle. Explore the wider external mouldings UK for coordinated wall and opening details.
