Sound Barrier Systems presents their Sound Barrier Secondary Glazing Systems, which serves as an effective method of reducing sound transmission through windows. They have been independently acoustically tested and verified to reduce noise transmissions by up to 80%.
These systems are ideal for strata units, townhouses, heritage style properties and free standing homes. The Secondary Glazing Systems suits all window styles and do not require the need for existing windows to be replaced.
The add-on glazing systems are installed on the inside of the existing windows, which creates a double-glazed unit that helps reduce noise transmission. The air pockets created between the original window and the Secondary Glazing Systems provide the insulated medium for both noise and thermal transmission. Both the original and glazed windows can be opened for cleaning and ventilation.
The Secondary Glazing Systems, from Sound Barrier Systems, also suit window replacement projects, new construction and renovations, especially when the highest possible noise reduction is required. The Secondary Glazing Systems can also be installed to Sliding, Double-Hung, Casement, Awning or Fixed windows.
