This falls well below the minimum specified in Approved Document E which is Rw29dB. When tested again with FAS Corner Seal in conjunction with FAS Drop Down there was an increase in the performance to Rw39dB (Tested) depending on door sets. Please check test table for exact results. Background All doors need a gap between the perimeter of the door and the door frame to allow the door to function correctly. These gaps allow doors to be opened and closed easily and accommodate any expansion/movement within the building. Consequently these gaps also allow sound, smoke, fire heat (hot and cold) etc. to permeate through the doorset assembly.
