Questions & Answers:

• Will installing more than one vent to achieve a greater free area have an effect on the acoustic performance? We asked the BRE who said "The performance of the ventilator will not degrade when you put in more of them. The composite sound insulation performance of the facade will degrade if you increase the number of ventilators, assuming that they are one of the weaker links."
• Will the vent reduce sound from inside to outside as well as from outside to inside? The BRE has advised us that it's reasonable to assume that 'reciprocity' applies to the vents. That is, the third octave values for sound reduction index are the same in both directions (out to in and in to out).
