Building Today has reported (01/04/2016) on a new easy to install acoustic insulation product released by Knauf Insulation.
Earthwool glasswool, made from recycled glass, is non-combustible and very quick to install in metal frame constructions. The 2.7m long folded insulation is compression packed and can be installed in one go because it does not require adhesives. This saves installation time and money.
One pack of this acoustic product covers an areas of 32.4 sqm2. The acoustic rating is 11kg/m3 providing a higher acoustic performance than polyester insulation.
A STC50 rating can be achieved with a typical 92mm steel stud with 13mm plasterboard on both sides compared with STC48 achieved by using a thicker polyester product.
No added petrol based chemicals or formaldehyde are used in the binder so customers can be satisfied that they are buying a sustainable product.
