Shaft Enclosure Fire Rated Walls On Roof Level
I have central AC system & air ducts are coming from roof through one big shaft. We have so many air ducts coming from roof through the same shaft. My questions are: 1. Shall this shaft on roof covered and constructed with fire rated walls? 2. Shall we install fire dampers on air ducts...- Waleed Ali
