SoundScreen dramatically reduces unwanted
noise transfer through walls and between floors
to create peace and quiet
Doctors and psychologists agree that noise has the ability to raise stress, disrupt sleep and generally
reduce your quality of life. There are a lot of reasons for the growing problem of noise pollution.
Acoustic insulation is typically installed in a wall cavity or between a first floor ceiling and second
storey floor at the time of construction. Therefore, if you are renovating, adding an extension or
building a new house – you should consider SoundScreen in the following applications to help
localise noise and limit disruption to adjoining rooms:
Home theatres Laundries
Study or parents’ retreats Nursery/kids’ rooms
Bathrooms/ensuites Mid-floors
