Artworks UK have been busy….

We are proud to launch our latest product range based on the ever popular ALTO acoustic surfaces. This high performance and design led product solution was born through and innovative collaboration with XSTONE.

The base layer is Artwork’s best-selling, eco-friendly focused 12mm acoustic PET ALTO panel, with 60% recycled content.

The XSTONE element is a roll material created entirely from recycled natural stone powder, carefully processed with eco-friendly, water-based binders and features a variety of naturally textured finishes, including concrete, wood and stone.

By laminating a selection of XSTONE finishes to 12mm ALTO, adding print and v-cut details – Alto X Stone was born.

Not only does XSTONE add visual depth, texture and tactile quality, it also improves the acoustic performance level and reiterates Artworks’ passion to push forward with natural, sustainability focused products.
