HOW DOES ACOUSTISORB WORK?
During the summer months, Acoustisorb, when laid horizontally as a ceiling or over purlin will reduce the downward heat flow entering by trapping the heat in the fibre. It works the same in winter by preventing the heat from leaving a building. The product retards heat flow, or slows down heat flow through the product. An important factor is thermal lag. Thermal lag means that after approximately 72 hours the heat on the one side of the product will be the same on the other. Therefore it is important to adequately ventilate the building as it will improve the performance of the product! With regards to the acoustic properties, owing to the density of the board and fibre and the softness of the material, any sound waves that approach the products behave in this manner:
|THICKNESS||DENSITY||WIDTH (M)||LENGTH (M)||R-VALUE|
|25 mm||50 kg/m³||1.2 m||20 m||0.74|
|35 mm||50 kg/m³||1.2 m||10 m||1.48|
|50 mm||50 kg/m³||1.2 m||10 m||1.48|
