ApplicationsVermiculite for Insulation
Lightweight mineral solutions for thermal insulation, fire-resistant systems and low-density construction materials.
- Insulation Mortar
- Fireproof Boards
- Loose Fill
- Lightweight Panels
Traditional mineral fillers and aggregates may increase system weight. Expanded vermiculite helps reduce bulk density and supports lightweight construction products.
Insulation systems need stable internal pores and low-density aggregates. Vermiculite contributes to thermal insulation through its expanded particle structure.
Boards, panels and mortars often need non-combustible mineral components. Vermiculite supports fire-resistant formulations subject to final system testing.
Lightweight mortars can segregate, collapse or become difficult to apply. Proper particle size selection helps balance flow, coverage and surface finish.
Expanded vermiculite reduces the weight of mortar, panels and boards while maintaining mineral-based formulation stability.
The expanded structure helps introduce low-density voids and supports heat-insulating performance in construction systems.
Vermiculite is widely used in non-combustible and fire-resistant systems, with final performance verified by the full formulation and test standard.
