many thanks a lot for this piece. Having said that, I have a matter, in calculating the overall stress fall per duct length. Are we taking into consideration the successful duration with the duct or just the size in the duct?
On the other hand, when sounds just isn't a priority, linear slot diffusers are good for top ceiling rooms. These are capable of throwing air within the ceiling to the ground in a peak of around 9-twelve meters most of the time.
