strapping?

sunsen | Posted in Construction Techniques on January 25, 2009 09:17am

I use the bulletin board at Chief Architect from time to time and there was something that came up not too long ago that I’m puzzled about. Apparently several of the folks who do framing in the northeastern part of the country use “strapping” or 1x furring strips perpendicular to ceiling joists prior to rocking and I’m unsure as to why. Anybody here familiar with this technique and as to what the advantages might be? I can’t see any from where I sit and I see a lot of downside. No big thing as I have no interest in adopting this style of framing, I’m just curious.

    We do strap all ceilings quite beneficial from my pov. Stapping provides sctructural stability to gable walls, makes interior partitions go up faster as you don't need to add blocking for nailers. Also makes electricians life easier. Why not strap?

  2. Piffin | Jan 25, 2009 10:11pm | #2

    There are a lot of advantages, and no disadvantages that I know of.

    Pros include the foillowing....

    when you frame with trusses at 24" OC, you need 5/8" rock on the ceiliong, but strapping at 16"oc lets you drop that to 1/2"

    When you use Thermax foam board to reduce thermal bridging, the strapping helps the electrician by providing a space and it gioves the required airspace for the radiant barrier to work.

    strapping on the bottom of floor joists adds integrity to the floor system to reduce vibration and decrease deflection better than bridging or blocking does.

    strapping a ceiling on first floor when there is a second floor reduces chances of floor vibrations telegraphing seams and nail popps.

    strapping between levels like that reduces sound transfer because there is far less solids contact between surfaces to carry the sound waves

    It is far easier for a sheet rock guy to hit strapping at 2-3/4" wide than it is to get his screw into a framing member at 1-1/2" wide.

    and last but not least, remember that the origin of this method was to level out a ceiling plane when the framing was rough hewn timber or sometimes even log poles, so it is an ideal way in remodel situations to bring the old back to a true plane again with a few shims.

    The ease of inserting partition walls was already mentioned.

      In our area it is unusual to see.

      I'm mostly with you on all points but unclear on one of your's:

      When you use Thermax foam board to reduce thermal bridging, the strapping helps the electrician by providing a space and it gioves the required airspace for the radiant barrier to work.

      And one from Cape Framer that stated that strapping a ceiling strengthens a gable wall?

      Care to give these a shot?

        That 3/4" space lets a sparky run wire to a ceiling fixture without penetrating the barrierThe space is necessary for foil to work as radiant barrier to ad effectiveness to insulation. With SR tight to a foil surface, it will not work as a radiant barrier.Not too sure on the gable wall except it it is balloon framed and you are using scissors t5russes for a modified cathedral ceiling.

            Which tickles the question that's been in the back of my mind...........

            What do you (strappers that is) attach the strapping with?

            And, do you just strap, or do you actually start checking and shimming a 15x20ft living room? 

          2. sunsen | Jan 27, 2009 04:25am | #53

            And I'm wondering how they handle exterior walls which run parallel to joists. Seems like you can't have the ends of the strapping hanging in joist bay.

             

          3. PatchogPhil | Jan 27, 2009 04:54am | #54

            If I understand your query.... all you need is a 2-by nailer scabbed onto the inside of that wall (whether it is an exterior or a partition wall). This nailer runs parallel and even with the ceiling joists.

            So the ends are toenailed, (never thought about the spelling of that)? 1x...? Or are they just loose or pressure fit? Does not compute, heh, heh!

            I see. That takes that edge of the sheetrock completely out of the picture, structurally speaking. Another reason that'll never be common practice in earthquake country.

            you had mentioned earlier that you weren't sure what I meant by strapping braces the gable end wall? Well your drawing shows it perfectly, without the strapping that would be one bouncy gable end.

            The more I think about it, I have to question why plasterers would want that. I mean, cracking is the biggest issue with that stuff. Maybe that's why they invented crown moulding, heh, heh.

            Now in these circumstances the practice makes a lot of sense to me. Uneven timbers, long spans, old fashioned lathe and plaster, I can see it. Otherwise, it's beyond me why people still do it.

            No need to check. By the time you are ready to strap you know if you need to shim if you've been working with your eyes open.8d rings mostly, but sometimes screws when you have to shim. Another trick is to tack it up with 6d brights, then drive shims as needed and tight nail with the rings.

            furring... by tradition... (2 ) 6d common... or (1) 8dmost of the time... just adding the new transverse layer will reduce the error by half, so no real need to shim... but if if something is way out... the furring can be shimedMike Hussein Smith Rhode Island : Design / Build / Repair / Restore

          "That 3/4" space lets a sparky run wire to a ceiling fixture without penetrating the barrier"Is sparky running that in metal conduit? I wouldn't want wires that close to the drywall...what if someone decided one day to cover the ceiling in paneling or t&g?I have never seen strapping used in Michigan. The only time I have ever seen it is on This Old House...but then I've seen them do a lot of weird/unnecessary things.DC

            "What if.That can make a Loooonng list."Some things are closer to the top of that list than others, though, and that's a "what if" that at least some code officials have already thought of:Our local BI won't let us run wiring in 2x4-furred walls, and hasn't for almost 20 years.And that's twice as much space as 1x.Not that I'm arguing either for or against what we call furring here. I always use it when I need to.AitchKay

          3. Piffin | Jan 27, 2009 08:14pm | #85

            In walls, we place the wiring same as always, where you still have the "What if" of somebody using too long of a siding nail or attaching braces to the outside with a 4" screw.
            ;)it is on ceilings that we are likely to use that space to run wires to the ceiling fixture to maintain the integrity if the VB there. My Electricians both tell me there is provision for this in the electrical code they are under here in Maine.

            This is from the 2005 NEC."300.4 Protection Against Physical Damage
            Where subject to physical damage, conductors shall be protected.
            ...
            (D) Cables and Raceways Parallel to Framing Members and Furring Strips In both
            exposed and concealed locations, where a cable- or raceway-type wiring method is
            installed parallel to framing members, such as joists, rafters, or studs, or is installed
            parallel to furring strips, the cable or raceway shall be installed and supported so that the
            nearest outside surface of the cable or raceway is not less than 32 mm (1 1/ 4 in.) from the
            nearest edge of the framing member or furring strips where nails or screws are likely to
            penetrate. Where this distance cannot be maintained, the cable or raceway shall be
            protected from penetration by nails or screws by a steel plate, sleeve, or equivalent at
            least 1.6 mm ( 1/ 16 in.) thick.Exception No. 1: Steel plates, sleeves, or the equivalent shall not be required to protect
            rigid metal conduit, intermediate metal conduit, rigid nonmetallic conduit, or electrical
            metallic tubing.
            Exception No. 2: For concealed work in finished buildings, or finished panels for
            prefabricated buildings where such supporting is impracticable, it shall be permissible to
            fish the cables between access points.
            Exception No. 3: A listed and marked steel plate less than 1.6 mm ( 1/ 16 in.) thick that
            provides equal or better protection against nail or screw penetration shall be permitted."Now the stuff below is the 2005 NEC Handbook. The handbook includes the code plus explanatory and background information. But it is not "code"."As shown in Exhibit 300.3, NM cables are positioned so as to equal or exceed the
            minimum clear distance of 1 1/ 4 in. that is required between the furring strip (wood
            strapping in this case) and the nearest edge of the NM cable as required by 300.4(D).The intent of 300.4(D) is to prevent mechanical damage to cables and raceways from
            nails and screws. Revised for the 2005 Code, this section recognizes that cables and
            raceways need the same level of physical protection at furring strips as they do at
            framing members where nails and screws are likely to penetrate. The Code offers two
            means of protection. The first method is to fasten the cable or raceway so that it is at
            least 1 1/ 4 in. from the edge of the framing member, as illustrated in Exhibit 300.4.
            This requirement generally applies to exposed and concealed work. The second
            method permits the cable or raceway to be installed closer than 1 1/ 4 in. from the edge
            of the framing member if physical protection, such as a steel plate, its equivalent, or a
            sleeve, is provided. (A steel plate is illustrated in Exhibit 300.2.) New for the 2005
            Code, Exception No. 3 to 300.4(D) permits the use of steel plates thinner than 1/ 16 in.
            to protect cables and raceways, but only if the plates are specifically listed and marked.
            As stated in Exception No. 1, the steel plate requirement does not apply to rigid metal
            conduit, rigid nonmetallic conduit, intermediate metal conduit, or electrical metallic
            tubing wiring methods because those methods provide physical protection for the
            conductors. "I have to reboot to get a better picture.But this is fron the Handbook.While this is suppose to be improved, the same basic requirements where in the 99 NEC. I have not tried comparing it word for word to see what was changed..

            no...  we  work  under  the  same  code

            all  it  means  is if  you run  wires between  the  furring and  under  a joist ,  you have  to  put  a  protector   plate  over   the  wire  WHERE  it  ducks  under  the  joist...

            not  a  big  deal... most  of  the  time  the  elec.  will still drill thru  the  joist

            but  occasionally.... like  in  a   remodel...  they  can  use  the  furring  space  and  the  protector   platesMike Hussein Smith Rhode Island : Design / Build / Repair / Restore

      So using TJI joists, (which I use exclusively), pretty much eliminates any of the apparent advantages to this system? Essentially just making it more work at greater material cost?

      1. Piffin | Jan 26, 2009 12:24am | #8

        Not at all. One common problem with TJIs is vibration. but making the floor system a sandwich with two separated diaphragms ( subfloor one side3 and strapping on the other) increases its stability measurably. Keep in mind that the strapping is run perpendicular to the joists.

        Its a regional thing. North eastern builders swear by it, elsewhere they don't seem to miss it. One minor point: Strapping makes your walls too short for two sheets of drywall.

        1. Piffin | Jan 26, 2009 12:36am | #10

          No it doesn't. Framing the walls too short for strapping is what makes the walls too short to hang two sheets. When you are going to use strapping, you frame for it.

            I think we can get two different sizes of precuts, but because all my stuff is on remo work and 9-10' ceilings, I never order precuts - I need to match what is there already for additions.

    No big thing as I have no interest in adopting this style of framing, I'm just curious.

    It's a Regional thing. The people who do it have always done it and believe in it. That's fine. You have never done it where you are, I don't do it where I'm from. I did do it when I framed in Cape Cod, but left it there when I went back to NJ. Keep doing what you do, you obviously don't need it.

      Well, to be honest, they wouldn't allow it here in California. It would decouple the floor joists from the sheetrock, which is considered a structural. We have nailing inspections for that here.

      If noise is a problem resilient channel is used along with varying sized layers of sheet rock, (something about varying frequencies).

      This makes sense to me only with regard to the original intent, which was mentioned, where you have uneven timbers, widely spaced. That I can understand. I can't really see a reason to continue the practice with engineered material. Framing here is almost exclusively 16 o.c. and we always use 5/8'' rock on account of it's a better job.

      Also, TJI's have knockouts designed for electrical runs. Couldn't be much easier.

      Another thing, it seems like splitting the 1x material has to be an issue when fastening sheetrock.

      Funny, I've just never heard of it till someone brought it up over at Chieftalk. Interesting.  

      1. Piffin | Jan 26, 2009 01:49am | #16

        Maybe I'm having a brain fahrt, but I don't know what you mean by that one. Why would you want to split the strapping anyways?

          He's thinking the 1x will split easier than joists when the drywall is screwed on.

        2. sunsen | Jan 26, 2009 02:08am | #18

          Well, I'm not sure what sort of 1x material you use but the 1x pine and fir we get around here is prone to splitting along the grain, especially when dry.

        "Well, to be honest, they wouldn't allow it here in California. It would decouple the floor joists from the sheetrock, which is considered a structural. We have nailing inspections for that here.

        If noise is a problem resilient channel is used along with varying sized layers of sheet rock, (something about varying frequencies). "

        I'm not a builder, so please forgive a stupid question: I thought the purpose of RC was to decouple the sheetrock from the framing members to reduce noise transmission, so I don't understand how that would be more structurally acceptable than strapping?

        1. sunsen | Jan 27, 2009 04:20am | #52

          First they put 5/8" rock on, get it inspected for nailing, then resilient channnel, then another layer of rock of a different thickness, (vibrates at a different frequency I believe). That's how it's decoupled yet structural integrity is maintained.

            Well, to be honest you don't see a whole lot in the way of sound walls around here in single family homes. Maybe if a bedroom backs up to a bathroom with plumbing or something like that. Theaters and such are generally isolated below grade. (Don't need a whole lot of windows in those, heh, heh).

            Thanks for the explanation. How is sheetrock considered structural? I've never thought of something that I can crumble in my hands, that disintegrates if a pipe leaks and that can easily crack if the wood it is nailed to moves, as having structural qualities.  I've always thought of it as a fire retardant and a place to put paint.  How does it contribute to the structure of the building?

          4. sunsen | Jan 27, 2009 05:10pm | #80

            Sheetrock definitely provides rigidity. I mean, just try racking a wall that has sheet rock on it as opposed to bare studs. I'm sure those engineers have calculated just how much and throw that into the overall calculations.

            In today's LA Times (emphasis mine, and I couldn't help but include some screw related information too):

            Initial observations by the assembled experts yielded some surprises. At 80% of the Northridge intensity, about half the bricks on one outside wall came tumbling to the ground. At 120% intensity, the other half came crashing down."I was not expecting to see this at this level," said Richard E. Klingner, professor of civil engineering at the University of Texas at Austin.But the 150% shake appeared to do little further damage to the exterior. And the 200% test only knocked loose a few bricks on a different wall.The wall whose bricks fell first had been constructed with a nail-like device that fastened the masonry to the wooden structure.The walls where bricks did not fall as easily were made with a screw-in device."This is not a failure of the masonry, it's a failure of the connection system," said Klingner. Earlier tests at 25% and 50% of the Northridge quake's intensity had shown no damage.At Monday's tests, the masonry on the outside was not the only focus. The experts were also interested in what happened to the drywall, whether it cracked or crumbled, and whether it provided structural support.Gary Hart, an emeritus professor at UCLA now working for a consulting firm in Marina Del Rey, said questions about drywall are often key to insurance claims involving earthquakes.

        Well, to be honest, they wouldn't allow it here in California. It would decouple the floor joists from the sheetrock, which is considered a structural. We have nailing inspections for that here.

        "decouple"? Do you build guitars?

        Sheetrock hasn't been allowed for structural in many years in the Bay Area and wouldn't ever be needed for shear on the bottom of a joist anyway. I wish they made structural sheetrock!

        Nailing inspections for sheetrock have been done away with by the new California Code. Yea! 

        I use RC all the time to level ceilings and for soundproofing. Proper installation includes a draft stop top and bottom of walls. It's as easy as running your ceiling rock tight to the top plate and caulking the bottom to the floor or adding a sheetrock strip at the bottom plate.

        Strapping? I have little use for it except under TJI's to stop the bounce.

          I'm in the bay area too. Been building here since 1985. Hawaii prior to that. Sheetrock definitely is part of the structural calculation. It doesn't replace shear panels but it counts. Hence the nailing inspection. The inspectors will tell you this as well as engineers.

        2. sunsen | Jan 28, 2009 05:36am | #92

          Oh, the "decouple" reference must have come from this radiant heating system I'm installing at the moment, heh, heh.

        3. sunsen | Jan 28, 2009 05:37am | #93

          I didn't read your post very thoroughly. Sheetrock nailing is no longer inspected? When did that come about? Interesting...

          1. klhoush | Jan 28, 2009 07:14am | #94

            I'm in San Anselmo and the new CA code (adopted last June here) doesn't require drywall nailing inspections. Floating corners were impossible under the old code. The building inspector is pretty good at keeping us educated and brings hand-outs about railings and thresholds.

            It does contain some accessibility language about 1/2" maximum threshold height. Try installing a patio door with that restriction.

            That's interesting. I'm doing a project in Portola Valley right now so I guess I'll find out about that nailing inspection thing pretty quick.

            The threshold thing, that's commercial, right? Otherwise, I'm going to have a bit of a problem with that.

          3. klhoush | Jan 28, 2009 06:57pm | #96

            San Francisco may not have adopted the new code and they have their own fire codes that take precedence. YMMV

            I stopped working over there years ago after realizing I'd have to spend a lot of time trying to figure out their codes before bidding a project. Add the commute, theft, and the parking hassles.

        Using resilient channel is useful in many applications, not just when the joists are uneven. No only does resilient channel assist with sound dampening, it also absorbs flex, vibration or shifting in any of the joists. This can be a problem in all joist materials. Though I recognize the immediate benefits of using 1by for strapping, resilient channel adds to these benefits.

        using a pre-cut stud of 92 5/8 plus a shoe and double plate will give you a wall of 97 1/4" ( some figure it as 97 1/8 .... which is the default wall in Chief Architect )when you strap the ceiling ( and only a hack wouldn't strap the ceiling ), it reduces the height to 96 1/2 " and 8 " sheet rock works fine without cuttingMike Hussein Smith Rhode Island : Design / Build / Repair / Restore

            You are not a hack at all. Mike is clueless if he's serious. There are thousands and thousands of houses that are not strapped that are worth millions of dollars Strapping is by CHOICE, it is not required ANYWHERE! You don't have to start something that is not necessary. If you feel like because Mike says people are hacks, go for it.

            People who strap don't no any other way to frame, so some think it is the best and only way to frame. To say that people who don't strap are hacks, is insane and ignorant.

            At the risk of starting a bun fight I'd have to disagree. Here, only the "B" grade builders don't strap. Even the plasterboard fixing manual tells us to strap for a better finish.

            Level 4 Finish

            At least 90% of measurements taken over any 1.8m span of the

            substrate shall not deviate from the plane by more than 4mm. The

            remaining 10% shall be within 5mm. A suitable levelling system

            must be used to correct deviations falling outside these tolerances.

            Use metal battens or furring channels on sliding clips to level

            ceilings and maintain independent movement. Plasterboard is not

            designed to provide lateral bracing. Supplementary bottom chord

            bracing may also be required.

             

            1.8m is about 6 foot and 4mm is just over 1/8th inch. Don't know about your lumber over there, but there is no way I can put a straight edge perpindicular to my truss bottom chords and achieve those tolerances.

             

            In addition our experience is that strapping adds substantially to increasing the buildings rigidity in the lateral plane ( and we build to some of the most strict hurricane codes in the world.)

            Mark,

            All the A builders and contractors here don't strap building all types of homes and additions costing millions of dollars. I could care less what the plaster board manual says. The finishers here must be much better than where you are if you need strapping to get a better finish because our ceilings come out just as nice as yours do. I lived and framed in Cape Cod and strapped. Ceilings ain't no prettier there than in NJ.

            We'll have to agree to disagree. You just don't need strapping period! Is it wrong to strap, no. Is it wrong not to strap, no! Do you need to strap, no! Millions of houses that don't get strapping and the ceilings are beautiful.

    I grew up in strapping country,,, moved away and started getting a lot of strange looks.

    Anyway, when you strap, it reverses the direction of the wall board, and a lot of times you will then have no butt joints on a ceiling.

    I was finishing a place last year, attic level, three doghouse dormers.
    It wasn't originally meant to be finished, and the framers gave no regard to hanging wall board. A few bundles of strapping and two hours later, we were in business.

    I have installed a lot of metal resiliant channel the last few years and that stuff really flattens out a ceiling. Very easy to work with.

    I can't get decent KD 1x3 here in southern Ontario. The yard stocks 1x3x8' propellers. I keep a few bundles of 1x4x16' (purchased green) in my shed to feed my habit.
