The casing is made of an external sheet of aluzinc, the inner sheet is galvanised on both sides, and the filling between them is mineral wool, which has very good thermal and acoustic properties. The thickness of the insulation is 30 mm. The device can be operated from the bottom or from the top, and from one of the two service sides – right or left.
