How to Insulate Block Buildings.
With specially formulated open cell foam for block buildings, we can inject fill into all cavities to greatly decrease energy loss. Other block fill insulation we have seen installed have one thing in common: They settle over time. This leaves many pockets along the entire wall system that are uninsulated, making energy sinks where controlled climate air is lost. With the formulated foam that we use, the foam will be injected into dime-sized holes with a high-pressure machine. Then with a slower-than-normal reaction time, it runs down into all voids and cracks, where it expands into every contour. Next, all holes will be cleaned and grouted. The entire process can cover hundreds of square feet in one day.
