Cupa 5 slate surface finishes
R – Relief: A naturally textured surface that retains the natural roughness of the stone. The most popular choice for roofs — relief emphasizes the characteristic split structure of Cupa 5 and gives the roof a lively, artisanal look.
H – Honed: A smooth and matte, lightly polished surface. Suitable for those who want the dark gray tone of Cupa 5, but a more restrained and even surface structure than the classic embossed option.
Natural: A raw, untreated surface — the closest to what the stone looks like after it has been quarried. The choice for those who value the authenticity of the material to the maximum, such as restoration projects and traditional architecture.
If you are in doubt about which surface finish is suitable for your building — ask for samples, we will send stone pieces to assess the tone and texture in real light.
Quick comparison of options
- R (Embossed) — the most commonly used option on Estonian roofs, suitable for both new and old buildings
- H (Honed) — the preferred option for buildings and facades with modern architecture
- Natural — mainly used on heritage sites and in the restoration of historical buildings
All three options are available in the same sizes and thicknesses — the choice does not affect the technical specifications, only the visual appearance of the roof.
