What is loose fill masonry insulation?
Perlite loose fill masonry insulation is an inert volcanic rock expanded by a special heat process and is often treated with water repellent material. The resulting granular product is lightweight with countless tiny, sealed air cells, which account for its excellent thermal performance and fire resistance.
How do you insulate existing concrete block walls?

Is perlite good insulation?
Perlite ore, when expanded, takes on a low- density cellular structure that makes it an extremely efficient high-temperature insulation material.
What is the R-value of vermiculite?
about R-2 per inch
Expanded vermiculite is lightweight, fire-resistant, and odorless; since it has an R-value of about R-2 per inch, it was used for decades as an insulation material.
How do you insulate masonry walls?
To improve energy efficiency, structural masonry buildings can be insulated, often by adding a layer of spray foam or rigid foam to the interior face of the wall. One problem with this method, however, is that it changes the vapor profile so that the wall can only dry to the outside.
Can you put insulation against concrete?
It’s not recommended that you apply fiberglass insulation directly to a concrete wall. If you must use fiberglass, there needs to be a space between the insulation and the wall. If not, the place where the insulation touches the concrete will be overtaken by mold and mildew.
