Acoustic Plaster

What Is Acoustic Perlite Plaster?

Acoustic perlite plaster is an acoustic and thermal insulation plaster applied directly to wall and ceiling surfaces, containing expanded perlite. Perlite is a natural volcanic rock that becomes lightweight and porous when heated, providing both sound absorption and thermal insulation thanks to this structure.

Key Properties

• Sound absorption and insulation: Its porous structure absorbs sound waves and reduces sound transmission between rooms or to the outside, making it effective for noise control in interior spaces.
• Thermal insulation: The perlite content helps reduce heat loss and improves energy efficiency.
• Lightweight: It is applied without adding significant dead load to the structure and is suitable on concrete blocks, gas concrete, brick, and light aggregate block surfaces.
• Fire resistance: Due to its natural inorganic composition it is non‑combustible and acts as a protective barrier in case of fire.
• Easy application: It can be applied by hand or machine, offering a practical and fast plastering solution.

Usage Areas

• Used as a base plaster in interior spaces where high acoustic and thermal insulation performance is required (offices, residential buildings, studios, movie theaters, and hotels).
• Applied on concrete, gas concrete, perlite blocks, and similar substrates to provide both surface leveling and acoustic protection.
