S4 Universal Mounting Systems
In-roof solar mounting solutions
S4 Roofit has been tested for external fire performance in accordance with CEN/TS
1187:2012 (Test 4) and classified BROOF(T4) under BS EN 13501-5 based on a tested roof-integrated configuration. The photovoltaic module references listed in this document are covered by an Efectis. technical assessment based on BROOF(T4) fire test evidence and are considered suitable for use within the S4 Roofit system, provided the installation conditions, system configuration and validity criteria of the assessment are respected.
All modules must be installed in accordance with the applicable S4 installation manual, project-specific design conditions and recognised roofing practice.
At UKSOL we’re committed to delivering solutions that combine industrial vision, innovation and on-site practicality. The S4 Universal system reflects this vision by empowering installers, developers and distributors to adopt one mounting platform across multiple roof types and project sizes — reducing complexity, improving quality and accelerating deployment of solar projects.
