Acoustik Perlite

What is Acoustic Perlite?

Acoustic perlite is a type of perlite used in construction and acoustic systems to provide sound insulation and sound absorption. Perlite is a natural volcanic glass rock; when expanded at high temperatures it becomes lightweight and porous, offering both thermal and acoustic insulation properties.

Key Properties

• Sound insulation and absorption: Its porous structure absorbs sound waves and provides sound insulation, especially effective at high frequencies.
• Lightweight: Expanded perlite has very low density, which reduces the weight of walls, screeds, and concrete toppings, lowering structural loads.
• Fire and thermal insulation: It is a natural, inorganic material, non‑combustible and highly heat resistant; it also provides good thermal insulation.
• Environmentally friendly and durable: It is chemical and biologically stable, does not rot or attract pests, and is non‑toxic.

Usage Areas

• Used in acoustic panels, wall and ceiling finishes, perlite‑containing screeds, and insulation plasters.
• Frequently applied in spaces where acoustic comfort is important, such as schools, concert halls, studios, office buildings, and hotels, to improve sound absorption and noise control.
