Understanding the Performance Differences Between Expanded Perlite …
The reason perlite insulation is technically referred to as "expanded perlite" is because when it is heated during the manufacturing process (to approximately 1600°F/900°C) the moisture expands, causing it to pop like popcorn at 1600°F. This makes perlite a very low-density material that is light-weight, with low thermal conductivity values.
Perlite in Construction: Reinventing Insulation & Concrete
How Perlite Helps: By integrating perlite into the mix, the weight of concrete can be reduced by nearly 20%. The resulting lightweight concrete maintains robust strength but is easier to handle, faster to set, and, crucially, puts less stress on the structures it's used in. This lightweight solution is perfect for floor fills, roof decks, and ...

AP-42, CH 11.30: Perlite Processing
Crude perlite expanded for use as a concrete aggregate ranges from 1 mm (plus 16 mesh) to 0.2 mm (plus 100 mesh). Ninety percent of the crude perlite ore expanded for horticultural uses is greater than 841 µm (20 mesh). Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled.
The Water-Holding Capacity of Perlite
The amount of water taken up by particles of perlite is largely dependent on particle sizes. Just as fine, clay-rich soil holds more moisture than coarse, sandy soil, different particle size distributions of expanded perlite hold more moisture than others (Fig. 2). Four example grades of perlite: Coarse, Medium, Fine, and Extra Fine
