One material, different characters Clean line or natural slate look.

Fibre cement slates make it possible to combine roof and façade cladding. Cedral has models for clean, modern lines and for more natural, texture-rich expressions.

The UV-cured protective layer is colourfast and low-maintenance.

The build-up A slate is only as good as the roof underneath.

Under fibre cement slates, too, we renew the roof as one system:

  1. 01Roof covering

    Roof tiles or slates

  2. 02Underlay

    Water and wind barrier, vapour-open — with counter battens and tile battens

  3. 03Insulation layer

    PIR, glass wool or stone wool — according to height and substrate

  4. 04Vapour control layer

    On the inside, limits moisture penetration from inside

How do you choose? Three choices determine the look.

  1. Surface: flat and matt (TECTA Smooth, Alterna) or with relief and a slate look (TECTA Texture, New Stonit).

  2. Edge: straight, chamfered or jagged.

  3. Colour: make your final choice on a current Cedral sample — colours on screen are indicative.

  4. Roof and façade in one material, or just the roof.

Questions about fibre cement slates What our clients ask us.

What is the difference with natural slate?

Natural slate is a natural product with a texture you cannot imitate. Fibre cement slates have a uniform, colourfast surface; TECTA Texture and New Stonit come close to the look of natural slate.

Can I use the same slate on the façade?

Yes. Fibre cement slates make it possible to do roof and façade cladding in one material.

What colours are available?

Alterna is available in nine colours, from crystal white to black; TECTA and New Stonit in shades of grey. Make your final choice on a current sample.

What warranty does Grava Group give?

We give a 20-year warranty on our work, in black and white in your quote.
