The utility model relates to the vacuum metallized units destined for application onto the glass surface of a metal layer, namely to the vacuum chambers. The vacuum chamber comprises a body (1) in the form of parallelepiped with branches (2) and a cover (3) with sight port (4). Onto the flat surfaces of the body (1) there are made vertical and horizontal stiffening ribs, to which by means of rests (9), there are fixed arched girders (11), the ends of which are rigidly fixed to the upper and lower edges of the body.
