Fire Rate Spray Foam, Help Setting Poles, and a Riding Arena

This Wednesday the Pole Barn Guru answers reader questions about code requirements for fire rated spray foam in enclosed parking structures, a request for assistance to set poles, and a question about the clear span of a riding arena.

DEAR POLE BARN GURU: Trying to find the NFPA code or Building code requirements for having to used fire rated spray foam in enclosed parking structures with sprinkler protection. Your help with this is appreciated. We went to the garage yesterday, and it is an enclosed garage with employee vehicles in it and pretty full. It is sprinklered with a dry system. The garage is already currently fire rated spray foams throughout. The owner had to install additional support steel beams due to deterioration and his architect told him the new code doesn’t require him to spray the new steel support beams with fire rated spray foam. Its an existing building and 90% was previously sprayed and still has a fire rated spray foam applied. He is questioning the new steel as it will cost him $60k to do. I can’t find any code on this currently and still looking. Just looking for insight from a company that does this and might have knowledge of the code for this type of application.

Your help is appreciated.

CHAD in STAMFORD

DEAR CHAD: Building is an S-2 occupancy. If structure itself is of non-combustible materials (steel/concrete) then it is Type I or II. As best I can tell from Code readings, his architect is correct – as long as member is not in an exterior wall or roof assembly where insulation is required for climate control. If it is in either of those areas, then closed cell spray foam is likely to be a best choice and as it is flammable, it would need to be either fire retardant, or covered with appropriate fire retardant material (e.g. Type X gypsum wallboard).

 

DEAR POLE BARN GURU: I need a referral for someone to set the poles on a pole barn 36 x 50. I am building it myself but need poles set correctly. Thank you. PATRICE in BIG LAKE

DEAR PATRICE: We have developed a significant list of independent building erectors covering much of our country’s contiguous 48 states. Provided you are ordering your building from us, we should be able to connect you with one or more of these independent builders who can assist you.

 

DEAR POLE BARN GURU: Can you make the pole barn riding arena kit 13 feet wide? TONY in DOUGLAS

Interior Clearspan ArenaDEAR TONY: My educated guess is you are actually looking for a width greater than 13 feet. Our clearspan limitation is 102 feet and unless you are doing professional barrel racing, we have not found a client yet who needed a width over this. Here is a little extended reading about riding arenas: https://www.hansenpolebuildings.com/2015/06/horse-riding-arena/

 

Gable Rake Trim, 24″ oc Framing, and Lap Siding Options

Today the Pole Barn Guru answers questions about cutting the rake trim at the gable end, Mike’s thoughts on 24″ oc framing for drywall, and types of lap siding options.

DEAR POLE BARN GURU: Can you advise me on how to cut sculpted rake trim at gable.  Pitch is 4/12.  This trim is a little hard to work with due to the angles that I suppose give it the name “sculpted.  Wanting to overlap the two pieces. 

Thanks, HEATH

DEAR HEATH: This excerpt from Hansen Pole Buildings’ Construction Manual should assist you:

At peak, See Figure 22-5 (when I piece ‘folds’ over peak) or Figure 22-6

Interior Wall FramingDEAR POLE BARN GURU: With lumber prices being what they are, what is your take on doing all interior framing on 24 inch centers and using all 5/8 drywall everywhere? Do you feel like it would be a significant enough savings to warrant it. I know that builders typically struggle with achieving dead flat walls even with 16 inch center framing. I’m willing to invest the time in choosing my framing materials to minimize the potential for waves. I guess it really just boils down to being able to accept slight imperfections in the wall in order to keep the project affordable. I’ll invite any opinions on this as long as it’s civil. RUSS in PIPERSVILLE

 

DEAR RUSS: I am a huge fan of using 5/8″ Type X drywall everywhere. In fact, I used it in our own shouse (shop/house). It offers several advantages, besides just an increase in fire protection. Its added stiffness hides a plethora of framing imperfections and it tends to lay smooth over framing two foot on center. We have found it to be very durable in holding up to my paraplegic wife’s power chair (yes, collisions do occur). Another often overlooked virtue – it dampens sound transmission through walls. For a couple of cents per square foot of material in my humble opinion it is a no brainer.

 

DEAR POLE BARN GURU: Do you have a siding option that resembles vinyl lap siding? CHUCK in HOGANSVILLE
