Acoustic products

About Acoustic products

We have a range of acoustic products to help with sound insulation in buildings. For new builds and conversions, sound insulation is essential to pass Part E of the building regulations. The Code for Sustainable Homes also has sound insulation credits available to help promote Health and Wellbeing and avoid complaints of noisy neighbours.
