Viroc panels appeal to architectural needs thanks to its’ natural appearance, which can be further enhanced by three different finishes: raw (unpolished), polished and sanded. The sanded finish highlights the visible wood particles on the surface of the board.


Viroc boards come with a 10 year warranty against deterioration and offer a European fire rating standard of B1. Viroc ventilated facade boards provide a high tolerance to moisture and give excellent thermal insulation for buildings. Other benefits of Viroc board include sound insulation (which varies according to thickness) and because of the natural composition of the board, Viroc is a eco-friendly, non-toxic material.

Viroc ventilated facade panels can be installed using a screw fix system or with adhesive, either onto a timber, aluminium or metal supporting structure. Please contact Pura Facades for full details on recommended fixing systems for varied applications of Viroc cement particle boards. General guidelines on Viroc board preparation:

Circular saws are ideal for thicknesses up to 19mm and for anything greater in thickness, the support of a workbench is recommended to ensure an even surface quality. For curved edges, a jigsaw is ideal (using the correct blade depending on wood or metal).

Conventional hammer drills are ideal for drilling.

The thickness tolerance of the sanded board is ± 0.3 mm. When the board is sanded, wood particles become visible on the board surface, enhancing the board’s natural appeal.

Machining of edges
Bevel, tongue-groove or half lap joints can be created onto the edge of the panel. The tooling pieces should be tungsten carbide.

Continuous and steady application is recommended to support a uniform finish to protect against UV and rain. Solvent based acrylic varnishes are ideal for application.

To help the longevity of the Viroc panel, it can be painted for decorative purposes with a large variety of paints or coatings.
