Openings up to 1 m wide
Openings in building units made from gypsum blocks up to 1 m wide require no door lintel and no reinforcing.
They are covered in the continuous gypsum block bond. Here, both edge gypsum blocks, if possible, should overlie the opening by 20 to 30 cm. For the possible remaining width an adjusting piece is cut to shape, which is installed between the edge gypsum blocks. As far as it is practical due to the height of the room the upper or lower row of blocks can be offset edgeways.
If the frame is installed at a later point and an assembly aid can be placed over the opening and removed once again after the gypsum adhesive has bonded, the shoulder of the wall next to the opening (remaining width of the wall) should be at least 10 cm.
