All four materials work as loose-fill insulation. Perlite and vermiculite are also used as aggregates for lightweight and heat-resistant castables. We select the bulk density grade from the certificate for the task.
Frequently asked questions
Can perlite and vermiculite be used as a concrete aggregate?
Yes, both are used as aggregates for lightweight and heat-resistant castables. Proportions are set by the castable recipe.
Perlite or vermiculite for loose fill?
Both are suitable for loose-fill insulation; the choice depends on the temperature and density requirements. Describe the task — we will select the material and grade.
