Replicating an aged metal surface, Iron Corten sintered stone was selected for various areas in the refurbishment of IV Centenário, a residential home in Brazil.
Ricardo Rossi of Ricardo Rossi Architecture and Interiors specified this surface from Neolith® by TheSize’s Iron Collection, both for its visual qualities and durability. “We wanted a hardwearing surface that would remain intact over time, and withstand the wear and tear that typically occurs in the home environment,” he explains.

With its stout orange hues inherent to iron oxide, Iron Corten provides a contrast of colour against the sophisticated greys and muted whites, while also complementing the earthy tones present throughout the property.

Versatile, durable and low maintenance
While a highly resistant satin finish is often favoured for commercial use, a matte finish was chosen for this project. Coupled with the scratch resistance and modulus of rupture afforded by Neolith, it gives a hardwearing integrity to the design.

Hygienic, waterproof, easy to clean and 100% natural, Neolith’s surfaces are versatile. “Neolith’s properties meant we could apply the panels to different rooms throughout the house in full confidence that the surfacing material possessed the qualities best suited to the functionality of that particular environment,” Rossi states.

Exterior application
Iron Corten could also be specified for the balcony facades, thanks to Neolith’s resistance to high temperatures and ultraviolet (UV) rays. “Due to the open-plan nature of the ground-floor layout, in which the outdoor area connects with the interior lounge, it was important for the surfacing material to not deteriorate under exposure to the sun and extreme temperatures,” Rossi points out.

Furthermore, with the connecting exterior featuring a swimming pool, Neolith’s near-zero water absorption and resistance to chemical cleaning agents meant exposure to pool water and chlorine would not affect the integrity of the material.

Covering large areas
Lightweight, a 3mm and 12mm Neolith panel weighs only 7kg/m² and 30kg/m² respectively. It also comes in different sheet sizes, including large formats measuring 3 200 x 1 500mm and 3 600 x 1 200mm, as well as bespoke options.

“Being able to cover large areas with fewer panels, combined with Neolith’s lightweight properties, provides installation advantages from a labour, time and cost perspective,” Rossi adds.

Ricardo Rossi Architecture and Interiors is also concerned with sustainability and whenever possible will specify eco-friendly materials. For the IV Centenário project, TheSize’s production processes and Neolith’s sustainable, ecological and 100% recyclable nature offered a product in keeping with this approach.
