    Insulation above suspended ceiling

    Yes, I specified an Armstrong ACT which supports up to 6" r19 insulation.

    Insulation above suspended ceiling

    Yes, AHJ may be the way to go at this point. I am just thrown off because it's a conditioned space inside of a semi-conditioned space so I wasn't sure if the insulation requirements would be more stringent.

    Insulation above suspended ceiling

    I don't believe IECC covers semi-heated spaces. ASHRAE 90.1-2013 does. Semi-heated spaces are generally spaces that are heated to prevent freezing and to take the "edge" off. This is also a category type when performing COMChecks. Think large industrial/warehouse buildings.

    Insulation above suspended ceiling

    The roof meetings the rqrts based on a semi-heated building. Given that office space will be fully conditioned, I'm not sure this will work.

    Insulation above suspended ceiling

    Thanks Paul. Is there anywhere in the building or energy code I can find information regarding this matter? Given that I've already instructed the contractor to lay batt insulation on the suspended t-grid, I'd like to have something to reference.

    Insulation above suspended ceiling

    The building is actually semi-heated and constructed of tilt-up concrete panels with r21 rigid insulation on the roof deck. Essentially there is a conditioned office space inside of a semi-condiitioned warehouse space.

    Insulation above suspended ceiling

    I am working on an office fit-out (B accessory use) in an S1 Use, Semi-heated warehouse. The perimeter office partitions only extend 12 feet up and do not go to the underside of the metal deck, which is about 40 feet up. My original drawings propose insulated walls with a suspended ceiling 10'...

    Converted 2-Family to 3-Family - New Jersey

    Thanks so much for the incredibly helpful reply! I owe you a beer! I believe my misunderstanding occurred the moment I encountered Section 903.2.8. Because the subsection doesn't make reference to R-2 specifically, I assumed sprinklers were not a requirement. This forum is an invaluable...

    Converted 2-Family to 3-Family - New Jersey

    Doesn't this essentially state that sprinklers are not a requirement unless exceeding 3 stories? § 5:23-6.26A Supplemental requirements--Groups R-2 and R-4 (a)Automatic Sprinkler System: Automatic fire sprinkler systems shall be installed in Group R-2 and R-4 as follows: 1.In Group R-2...

    Converted 2-Family to 3-Family - New Jersey

    Although Zoning allows for a 3-family dwelling unit in this particular area, we would be required to file for a variance given the lot size / existing built sq. ft. I have checked with the local fire subcode official regarding the sprinkler requirements and he seems to think the building would...

    Converted 2-Family to 3-Family - New Jersey

    Thank you for your patience and the provided information. I was getting myself turned around jumping from Rehab Code to Residential, to Existing Building Code and NJBC!! Do you have any experience converting 2-family to 3+ dwelling units?

    Converted 2-Family to 3-Family - New Jersey

    Rick, so in NJ anytime a new 1 or 2-family house is built, sprinklers are required? I need to study the code book! Unfortunately, most of my experience has been working in NYC on renovations and mixed-use projects, so existing residential is something I'm not well versed in.

    Converted 2-Family to 3-Family - New Jersey

    So it appears when converting from a 2-family to a 3-family, a change of use and occupancy is required, from R-3 to R-2. Because of this, there is an increase in hazard. When converting from a 2-family, to a 3-family residential building, I would either have to sprinkler the entire building or...

    Converted 2-Family to 3-Family - New Jersey

    I spoke with the local Fire Subcode Official and he believes it would require the entire building to have sprinklers installed, but I was seeking the opinions of other's on here in the event we may be overlooking something. I am still awaiting my NY/NJ License so I'm not in a HUGE rush, but I...

    Converted 2-Family to 3-Family - New Jersey

    Just discovered this forum exists by way of Archinect. This looks to be an incredible resource! What led me to post on here is I have someone interested in converting an existing 2-family, 3 story residential building into a 3-family in New Jersey. Based on my research via the Rehabilitation...
