Dissemination and Planned Demonstrator of New Precast Concrete Sandwich Panels

This paper presents work developing thin precast concrete sandwich panels for recladding and overcladding applications. These panels are designed for the retrofit of precast concrete structures where the underlying frame is structurally sound. Structural and thermal testing has been carried out to validate the performance of the panels. The panels are designed to have thermal performance better than current national standards, and this has been verified through hot-box testing of components and small-scale panels. Structural performance of the panels has been tested with 3 point bending tests on full-scale panels. Work is in progress towards demonstration of the panels on an occupied building in the UK
