Acoustic Insulation for Ceilings

Mustwall 18B & Mustwall 33B Acoustic Insulation for Ceilings

The Mustwall B range offers high-performance acoustic insulation in two sizes, 18B and 33B, designed for easy installation in existing environments.

Mustwall 18B: A 20mm-thick acoustic insulation panel, featuring a 7mm layer of high-density SBR rubber granules made from End-of-Life Tyres (ELTs), bonded to a 12.5mm plasterboard slab. Mustwall 33B: A thicker 33mm panel, incorporating a 20mm SBR rubber layer from ELTs, also coupled with a 12.5mm plasterboard. Both sizes are pre-assembled and ideal for acoustic upgrades of masonry party walls, offering exceptional soundproofing while minimizing space loss. Mustwall B panels provide a straightforward solution for enhancing sound insulation without extensive construction or the need for metal frameworks, making them perfect for residential and commercial applications alike. It’s important to note that when used in a false ceiling situation, the performance of Mustwall B panels differs from when used in wall applications. This factor should be carefully considered during installation to ensure optimal acoustic results. With their durable construction and easy installation, Mustwall B panels are an efficient and eco-friendly choice for acoustic renovations, ensuring long-lasting performance and improved acoustic comfort.
