Rhyl High School will reopen on Monday after safety tests on its cladding.
The school, which moved into its new £25 million home last year, was closed for two days after Denbighshire County Council found the external cladding sheet was made by the same American firm which provided cladding for the Grenfell Tower in Kensington.
The council has now ruled that the school’s fire safety procedure is fully compliant, there is no added risk of a fire and its safety management is sound.
In a joint statement, the council and the school said ”full and rigorous tests and assessments have been carried out by a team of professionally trained, qualified safety experts. These tests have looked at fire safety procedures, evacuation processes and checking of all other safety measures.”
They added that they believed ”the safety of pupils was paramount and that additional safety checks were necessary.”
Headteacher Claire Armitstead said on Wednesday that the new school had horizontal and vertical firebreaks, full coverage alarm and sprinkler systems and a half-hour fire rated internal plasterboard layer to the cladding system. Its design was approved by a fire engineer.
