Roof Slates

Swisspearl Berona Xxtra

Swisspearl Berona Xxtra is an attractive, smooth, flat, square-edged slate that is manufactured to the highest European standards. Berona Xxtra slates are durable and are an economical alternative to natural roofing materials. They are lightweight, pre-holed and easy to handle and install.

Berona Xxtra slates are produced in accordance with ISO-9001 (Quality Management System), ISO-14001 (Environmental Management System) and carry the Environmental Protection Declaration EPD-CEM-2012211.


Berona Xxtra slates are manufactured using Portland cement together with a non-asbestos formulation of superior blended synthetic and cellulose fibres. The slates are pigmented during production and are fully compressed. Berona Xxtra slates conform to class B in strength, the highest classification for fibre cement slates which are manufactured in accordance with European Norm EN429 – the European Standard for the manufacture of fibre cement slate. They are finished with a high-quality semi-matte acrylic coating to the top face and edges, with a tinted high-performance binder applied to the back face.

Berona Xxtra slates carry a 20-year colour and 30-year structural warranty when fixed in accordance with the latest versions of SR 82 Irish Code of Practice for slating and tiling and BS5534
