At Norcal Perlite, quality is engineered into every grade we deliver across Oregon’s diverse industries—from greenhouse growers in the Willamette Valley to contractors building energy-efficient structures along the coast.
Each batch of our expanded perlite is processed and tested in-house to ensure uniform particle size, low dust, and dependable performance in horticulture, construction insulation, and industrial filtration.
By controlling production from mine to market, we supply perlite that meets strict specifications for aeration, drainage, thermal resistance, and lightweight strength, helping Oregon’s growers and builders work cleaner and more sustainably.
