Perlite Insulation Plaster

(Thermal and Acoustic Insulated Lightweight Plaster)

Perlite insulation plaster is a cement-based, lightweight, and high-performance plaster solution used for both interior and exterior applications. It enhances the energy efficiency of buildings and provides long-lasting protection by combining thermal insulation, sound insulation, and water-repellent properties.

Thanks to its porous structure, it allows walls to breathe while helping to prevent moisture formation. Being significantly lighter than traditional plasters, it does not impose extra load on the structure.

What is Perlite Plaster? Where is it Used?

Perlite plaster is a special construction material used on brick, concrete, briquette, and aerated concrete surfaces, providing thermal and sound insulation.
