does anyone have experience air sealing fire sprinklers?

 

Per California code, all new  homes must have fire sprinklers.... think 30 to 40 holes in the ceiling.

 

Per installer, you can't foam/caulk the sprinkler as this will make it inoperable or void the warranty.

 

Any ideas?

Yep its called a hot roof assembly

I would check the manufacturers directions / website but you will probably end up using something like tenmat covers over them

Sean,  Thanks for the suggestion, but just to confirm, the manufacturer is hot roof assembly?  please verify.  Thanks.

Sorry, you asked for suggestions & the best one is to go with a hot roof assembly (http://bit.ly/HotRoof)

I would simply ask the installer for the manufacturer & model info if they don't have the specs handy. With that you can generally find a mark / info on the head

Sean,  Thanks for clarifing... I didn't know that "hot roof assembly" referred to conditioned attics.  Unfortunately that won't work with this builder.  The builder is a medium size production builder who is not ready to make that big a leap.

My pleasure & let me just quickly state - being in Cali with the new Title 32 (?) stuff coming out, he might find it cheaper & easier - definitely worth giving it a shot 

Check out this study from DOE: http://www.nrel.gov/docs/fy13osti/56667.pdf

Great.  How timely is this!  and I'm on a BA team.  Thanks.

Great document - however they give short shrift to my preferred recommendation which is to install wall heads - get ALL the pipes out of the attic.  I don't care how well you do the "tenting", I can still see the path of the pipes with IR on a cold day in zone 4.
