Abstract

A structural unit having a frame, a connecting face that surrounds an opening and a cover that is attached to the connecting face to cover the opening. The frame and the cover are formed of materials with different coefficients of thermal expansion, and the connecting face has a channel that opens towards the cover. At least one duct communicates with the channel so that when a filling compound is injected into the duct it is received in the channel. The filling compound thereby attaches the cover to the frame and provides a seal therebetween.
