Composite Stone – Window sill (interior and exterior)

by Holonite · Netherlands · CON213 · Published 04 Sept 2025
About this material

Interior
Holonite window sills are available in three different variants: flat, L-type and angled. They are also available in various colours and textures. They are delivered to order and are processed as required, e.g. cut to length and with holes or recesses.

Exterior
Holonite supplies a wide range of window sills, from extremely slim types with a front view of 15 mm to large, sturdy variants. All window sills are lighter as standard due to the strength of the composite stone used as the primary material. As well as conserving materials, this is highly beneficial when it comes to processing the products.
