External wall & facade mouldings

Decorative detail for external walls and facades

External mouldings are decorative architectural profiles fitted to the outside of a building. External wall mouldings and external house mouldings add proportion, depth and character to facades and openings—framing windows and doors, defining storeys, or finishing rooflines.

For rendered elevations, they create the look of traditional cement mouldings without pretending to be timber. Kayvic’s outdoor range is made from lightweight EPS with a Hyper Polymer Coating, keeping it lighter and practical to handle.

Unlike interior plaster cornice, external mouldings need to cope with rain, sunlight and knocks during service. These weatherproof profiles suit careful period-property renovation, new homes and commercial facades that need a more considered architectural finish.

The look of traditional cement mouldings, without the weight

Kayvic external mouldings are made from lightweight polystyrene coated with a Hyper Polymer Coating. The system gives the look of traditional cement mouldings but is lighter, stronger and more durable.

The coating is waterproof, UV-resistant and impact-resistant, making these weatherproof exterior mouldings well suited to changing UK conditions. Once installed and finished, they can be painted with suitable standard exterior paints.

Design an elevation

Where exterior mouldings are used

Use individual profiles as restrained details or combine them into a complete facade scheme. Explore each application before choosing from the Kayvic external range.

Banding & String Courses

Create clear horizontal lines across an elevation, divide storeys or add definition around rendered sections. Lightweight banding gives a facade architectural structure without the handling weight of traditional cement mouldings.

Window surrounds & architraves

Frame windows with heads, cills and side details that add depth to traditional and new-build elevations. Exterior window surrounds and architraves can introduce period character or a cleaner contemporary outline.

Door surrounds & architraves

Give entrances greater presence with lightweight external mouldings around door openings. Door surrounds and exterior architraves can form simple frames or more substantial architectural entrance features.

Exterior cornice

Use cornice profiles at rooflines, soffits and fascias to finish the top of a facade and create strong shadow lines. The coated lightweight construction makes larger details easier to handle.

Render mouldings

Add decorative external mouldings to rendered elevations for new builds, renovations and period-property updates. Use wall details, corners and banding to give a facade a more considered finish.

Yes. Kayvic external wall mouldings are designed for outdoor architectural use. The Hyper Polymer Coating is waterproof, UV-resistant and impact-resistant, making the profiles suitable for exposed UK elevations when correctly specified, installed and finished with suitable exterior paint.
