Dual protection: effective sound absorption and excellent thermal insulation
The ALAMENTTI MW S PERF acoustic sandwich panel is a specialist engineering solution designed for buildings where acoustic comfort, fire safety and energy efficiency are of critical importance. Its unique structure, combining a high-quality mineral wool core with a precisely perforated steel facing, enables effective attenuation of various types of noise – both airborne and impact noise – while significantly reducing sound transmission between adjacent spaces.
ALAMENTTI MW S PERF panels are ideally suited for use in:
- production halls
- logistics centres
- open-space offices
- schools and educational facilities
- healthcare buildings
- cultural and public venues
This system is an ideal solution wherever strict occupational safety regulations, high aesthetic standards and long-term durability must coexist with advanced acoustic requirements.
