Eastern High School in the United Kingdom is an education project associated with CSP Architectural’s Siniat plasterboard and Siniat Weather Defence™ systems. Weather Defence™ provides an external sheathing solution for framed construction, while the broader Siniat range includes plasterboard products for internal wall and ceiling applications. CSP Architectural lists both systems for this school project, demonstrating how external sheathing and internal lining products can form part of a coordinated specification for educational building construction.
