Abstract
An insulating building block which is a composite of masonry material and a foam material is disclosed.

A shield insert may be employed to define that portion of a block cavity which is to receive the foam.
Claims8
A method for forming a composite insulating building block which comprises:
- a. disposing a shield insert within at least one original cavity of a hollow building block to form a relatively smaller cavity between the shield insert and a longitudinally extending side face of said original cavity, said shield insert extending from top to bottom of said original cavity when disposed in said original cavity;
- b. dispensing a foam material into the smaller cavity between said shield insert and the side face of said original cavity;
- c. allowing said foam material to solidify as it adheres to the side face of said original cavity, thus forming a layer thereon;
- and
- d. removing said shield insert from said original cavity.
