Abstract: A thermally insulated masonry block includes pairs of spaced opposed side walls and web walls defining a cavity. A rectangular thermally insulative plate is disposed in the cavity and extends from one web wall to the other. The plate and side walls are spaced apart to define air cells. At least two aligned stub walls project into the cavity from the side walls to reinforce the side walls. The stub walls are of substantially the same height as the side and web walls and are spaced apart by a distance approximating the thickness of the insulative plate.

Abstract: A masonry block includes pairs of opposed side walls and opposed web walls forming a cavity therebetween. One of the side walls is apertured to conduct sound waves into the cavity. A panel formed of acoustically insulative material is disposed in the cavity and is spaced from the side walls to form front and rear sound damping chambers therebetween. Sound waves passing through the apertured side wall enter the front damping chamber and are subjected to a damping action within the block. Various sizes, shapes, and patterns of openings in the apertured side wall can provide varying sound damping effects. The panel may be inclined at an acute angle relative to the apertured side wall. The block cavity may be divided into cavity portions of different volume to provide for effective sound damping of high and low frequency sound waves.

Abstract: A masonry block comprises pairs of spaced opposed side walls and spaced opposed web walls forming a cavity therebetween. An insulative plate of thermally insulative material is disposed within the cavity. The insulative plate extends across the cavity from one to another of the web walls. The side walls each include a portion spaced from the insulative plate so as to define an air cell therebetween extending from one to another of the web walls. The side walls each further include another portion projecting into engagement with the plate to form an air barrier extending across the air cell from one to another of the web walls. Upon forming a wall with such insulated blocks, the air cells are sealed-off from one another to limit convection within the wall.

Abstract: A masonry block is disclosed having a pair of spaced opposed side walls forming only a single cavity therebetween. The side walls define the outer side periphery portions of the block and include mutually facing inner surfaces. At least two opposed web walls extend between the side walls. The web walls have inner surfaces extending between the inner surfaces of the side walls. The web walls include channels situated intermediate the ends of the inner web surfaces. The channels extend in a top-to-bottom direction and converge toward the bottom of the block. An insulative plate of thermally insulative material is disposed in the cavity with the ends thereof being mounted in the channels. The insulative plate is situated intermediate the side walls to divide the cavity into a pair of air cells separating the insulative plate from the side walls. The single cavity formed between the side walls may be partitioned into a plurality of cavity portions by one or more intermediate web walls.
