EI60 window for Salquenen school

very large windows with a fire protection rating of 60 minutes were produced for the school in Salquenen.

These EI60 windows measuring 1900 x 3400 mm (width x height) separate the stairwell from the gym.
Initially planned in 2 parts, these elements could be produced in 1 piece in our workshops.
Their installation required the use of 2 crawler cranes to handle these larch windows weighing more than 700 kg each.
