It’s a breakthrough in materials technology – a patented triple composite of polymer resins, inorganic minerals and acrylic colourings. Its minimal contraction and expansion, whatever the weather conditions, means no rectification visits. With the aluminium rail and fixing system, there’s no mortar or rendering involved in the installation, and easier to handle than cement boards. There’s practically no maintenance required for at least 10 years, and Coastline is 100% recyclable.
