A concrete building block for masonry block walls is formed with first, second and third spaced rectangular face shells, where the second face shell is intermediate the first and third face shells. First and second cross webs connect the first and second face shells and a third cross web connects the second and third face shells. Insulating cores include end protrusions extending outwardly at the top edge thereof to fit into notches of the cross webs and include cutouts to accommodate mortar crumbs. The insulating cores further mate, creating an overlap that serves to (i) insulate against temperature transfer and (ii) provide a sound barrier. A unique block permits a combination of insulating inserts and solid grouting as well as a symmetric arrangement.

A module, in particular for a building, includes a wall having at least two, preferably parallel, wall outer sides, which are spaced apart from one another. At least one channel is disposed between the two wall outer sides and is filled with a self-curing material. A building including at least one module, a method for producing a module, a method for producing a building wall and a method for producing a building, are also provided.

The insulatable cementitious building block is a concrete block formed with first, second, and third spaced parallel rectangular walls, where the second wall is half the height of and is intermediate to the first and third walls. First and second vertical end cross webs connect the first and second walls from the bottom of the first and second walls to the height of the second wall. First and second spaced intermediate vertical cross webs are in planes between the planes of the end cross webs and connect the second and third walls. These intermediate cross webs are also from the bottom of the second and third wall to the height of the second wall. The first, second, and third walls together with the cross webs form openings that accommodate inserts. Alternatively, the spaces may be filled with liquid expandable foam.

The insulatable cementitious building block is a concrete block formed with first, second, third, and fourth spaced parallel rectangular walls, where the parallel walls are connected by offset and constricted cross-webs in parallel planes to each other and perpendicular to each of the walls. All the cross webs are from the bottom of their corresponding walls to the height of the second and third wall. The walls together with their cross webs form openings that allow for filling with insulating inserts dimensioned to fill the spaces between. Alternatively, the spaces between all walls plus the spaces above the second and third walls and above all cross-webs may be filled with liquid expandable foam.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins. Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A block is disclosed that includes a top surface, a bottom surface, a pair of sidewalls, and a pair of endwalls. The block also includes a projection that protrudes beyond the top surface along a first axis and is symmetrical along a second axis and a third axis. The block also includes a recess that extends into the bottom surface along the first axis and is symmetrical along the second axis and the third axis. The block also includes a pair of trenches including a first trench and a second trench that are respectively defined by a recess extending into an endwall of the pair of endwalls. The pair of trenches both run along the first axis from a surface of the projection to a surface of the recess, and a first width of the first trench overlaps with a second width of the second trench along the third axis.

A bridge to construct a multi-stage wall is provided with a clip at each end. One of the clips is sized and shaped to fit snugly onto the wall of a standard concrete masonry unit (CMU), while the other is sized and shaped to fit onto a segmental wall system (SWS) unit. A retaining or stand-alone wall is constructed by laying a row of SWS units and a row of CMUs roughly parallel to each other, with bridges extending between them to fix the units. The hollow spaces in each unit and the space between the rows is filled with gravel, rock or other fill material as each course is laid. Additional courses of SWS units and CMUs are placed on top of the prior courses, with bridges added to each course. This process is repeated until the desired wall height is reached. Various sized and shaped clips and connector brackets are provided to allow spacing of the walls at different distances, with varying blocks. Multiple walls can be constructed in parallel and connected with bridges to provide sufficient retention mass for taller walls.
