Welcome to the fold: new acoustic product launched

A new non-combustible acoustic insulation product that provides a quick and easy-to-install solution for metal frame construction has been launched by Knauf Insulation.

Earthwool glasswool is an acoustic 11kg/cu m, 2.7m long folded product which can be installed in steel framing in one go. Because it holds firmly in place it doesn’t require adhesives, saving valuable installation time. 

Furthermore, it is compression packed, and will recover to its intended thickness when opened, allowing for more product per pack — resulting in less transport and storage on site.

Just one pack of 11kg/m3, 50mm acoustic product will cover an area of 32.4 sq m2!

In comparison to polyester insulation, the new insulation provides higher acoustic performance.

For example, in a typical 92mm steel stud with 13mm plasterboard on both sides, the STC result from using the new product is STC 50, whereas a thicker polyester product (90mm) only achieves STC 48.

It is made using recycled glass and with ECOSE Technology, a revolutionary binder that contains no added formaldehyde or petro-based chemicals.

The natural brown colour represents a level of sustainability and handling for glasswool never before achieved.

Installing the product, will not only save you time, but will help your customers enjoy a more peaceful and comfortable environment.
