modularArts® creates fluid wall surfaces in rock that dance with light and shadow. Manufactured with gypsum and lightweight aggregates, their modules can be joined on-site by standard tradespeople and blended seamlessly in a manner similar to drywall. The materials are non-combustible, durable, and do not off-gas. The company's new InterlockingRock® Blocks actually become fully dimensional walls. They create double-sided walls and allow varying degrees of light to pass between spaces.
