- After thorough research and scientific tests at the WTCB - laboratories
at Limelette (Belgium), Promagglo (double) walls can meet the
most stringent acoustic requirements.
- Promagglo walls consist of two gypsum walls with different thickness
(and in some cases having a different density), a special acoustic
foam insulation,
a combination of peripheral insulation strips and an Elasto WP12
flexible junction at the ceiling.
