Boiler Room Rules??
I am re-doing our block boiler room in a four family row house. We have been told that we need to install two layers of 5/8″ drywall (which we have done), but also cover that with sheet metal. Our questions are: 1.Do the layers of drywall in the ceiling need to be taped and compounded?…
I am re-doing our block boiler room in a four family row house. We have been told that we need to install two layers of 5/8″ drywall (which we have done), but also cover that with sheet metal.
Our questions are:
1.Do the layers of drywall in the ceiling need to be taped and compounded?
2.Do the sheets of galvanized sheet metal need to be overlapped?
3.Any other tips or rules about the regulations.
4.We are also doing the basement ceiling in single 5/8″, do these joints need to be taped?
Hi Brucef
–The construction of the boiler room should be one hour rated.
–Your minimum clearance for boiler equipment is 6″ above top of casing and equipment. Side, back and front clearances depend on what kind of system you have.
–You need sheet metal IF you are trying to reduce the required clearances. This is governed in the building code (you could look it up online) Reference Standard RS 14-16. You’ll see there are 9 different combinations of materials which govern these clearances (i.e. you could reduce the clearance to 2 inches with 28 gauge sheet metal and 1/8 inch asbestos millboard). It is not a one step answer, in other words.
–Fire ratings are not dependent on a specific material. They depend on the entire assembly of the room. Your engineer or architect are required to certify the firestopping and should be advising you on this assembly.
Hope this is helpful
How about sheet metal on the ceiling above the burner? And how far away must it extend?
1.you don’t need both drywall and sheet matel, and they must be taped and compouned
3. watch for clearance around units
4. you need 1 hour rating, 1 layer usally is not sufficent, all that need be rated must be taped!
