Resistance to the passage of sound
Manufacturers of cladding and curtain wall systems provide notional sound-resistance
figures for their products. The figures provide a useful guide to the expected noise reduction
of a particular construction; however, the actual detailing at the cladding and curtain
wall, especially at the junction with the structural frame, will affect the actual values. The
most effective way of reducing impact sound is to isolate the potential source of impact
from continuous solid transmitters such as structural frames. Resilient fixings to door
