VELFAC and CWCT worked together to develop both the test rig and testing sequence; the whole test procedure was undertaken by Taylor Woodrow and overseen by CWCT. Having worked so closely with CWCT, VELFAC Plus achieved CWCT system certification on successful completion of Tests 1 to 6. This provides official CWCT accreditation of VELFAC Plus, a greater achievement than simply gaining a
successful test report from a testing house, thus ensuring specifiers an increased level of confidence in the performance of VELFAC Plus within their own projects.
