14kg/m3 Knauf Earthwool® Glasswool Internal Wall Acoustic Insulation
The Earthwool® glasswool acoustic insulation range has been designed to meet or exceed the New Zealand Building Code in incredibly cost effective ways.
Knauf’s acoustic insulation segments and rolls are designed to be flexible and can be used in wall, ceiling, underfloor and sound absorbing applications. Earthwool acoustic insulation is rot-proof, non-hygroscopic (doesn’t absorb airborne moisture), has practically no smell, does not sustain vermin and will not encourage the growth of mould, fungi or bacteria. It does not contain added phenol, formaldehyde or artificial colours (dyes) and is provided with a 50 year warranty from the manufacturer Knauf Insulation.
New Generation Acoustic Glasswool Insulation
Earthwool is a new generation of softer, safer and more environmentally friendly glasswool insulation. Knauf Insulation’s advanced compression packaging reduces handling time and also the risk of damage in transit, storage and on-site. Earthwool glasswool insulation is supplied in pre-cut rectangular segments at 580mm width to suit the common wall joist centres, and it is considered to be the least itchy of all the glasswool brands.
Knauf acoustic wall insulation is recommended mainly for installation in the internal walls of the home. It is very effective in reducing noise transfer between rooms, but if installed in the external walls will also greatly reduce the amount of airborne noise disturbance from outside which enters the home.
Noise, Stress and Sound Insulation
The primary reason to install insulation is to reduce the effect of outside temperatures inside your home. Properly installed thermal insulation will keep you warmer in winter and cooler in summer. But when choosing insulation, you may also want to consider acoustic insulation, which reduces the transfer of noise. Excessive exposure to unwanted noise can lead to stress, sleep disturbance and numerous other health complications.
