Field Fusion Recap: The Disconnect Between Fire & Energy Codes

The Q3 Field Fusion event delved into air-sealing and sound transmission challenges in multi-family units through a guided discussion that included perspectives from Code Officials, Insulators, and Raters. Read more here.

There are many complexities that accompany building townhomes and duplexes.  For example, townhomes and duplexes built with common fire separation walls (party walls) are twice as leaky as single family houses that are twice their size.

Why?

The shaft wall, which we see most often in Colorado, is open directly to the outside through the designed gap between the shaft liner and the framing, thus creating a leaky assembly.  An additional complexity arises when the reduction of unit-to-unit sound transmission is taken into account, which requires correctly installed insulation.

EnergyLogic’s August 31st Field Fusion delved into the details of these assemblies through a guided discussion that included perspectives from Code Officials, Insulators, and Raters.

Clarification: What Part of the Shaft Wall Assembly is Fire-rated?  recap-of-ff-image_1

We must first define what part of the shaft wall assembly is fire-rated, as the entire assembly is not.  This is an important distinction that allows for more air sealing options once understood.

In chapter 3 of the IRC, Section R302 “Fire Resistant Construction” and Section R302.2 “Townhouses” states, “The common wall shared by two townhouses shall be constructed without plumbing or mechanical equipment, ducts or vents in the cavity of the common wall. The wall shall be rated for fire exposure from both sides and shall extend to and be tight against exterior walls and the underside of the roof sheathing.”

This statement in the IRC is our first indication that the two layers of sheetrock in the shaft liner wall are the fire-rated two-hour wall, designed to slow the spread of fire from unit to unit.  Thus, the two layers of 1” drywall cannot be penetrated with ducts.

The framing (which is held off the fire-rated assembly by a clip) often has ducts or plumbing in it and is specifically designed to burn and separate from the two-hour assembly when the clip melts.  This allows one unit to burn and fall before fire is able to pass through to the adjacent unit.  The UL (Underwriters Laboratory) listing for many of these assemblies’ references section 705 of the International Building Code (IBC) which states in Section 705.2 “Structural Stability”, “Fire walls shall have sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall for the duration of time indicated by the required fire-resistance rating.”  This is another indication that UL listings and the code are in agreement that the fire assembly is the two layers of 1” drywall and not the framing adjacent to the drywall.

recap-of-ff-image_2

It is important to point this out because throughout Colorado there is not a common understanding of what constitutes a shaft liner fire-rated party wall assembly.  Some jurisdictions still hold that the assembly is the drywall, air gap, clip, framing and interior drywall while others hold that it is as explained above.   What is consistent is the understanding that the assembly must be built continuously from the foundation to the roof deck.

EnergyLogic suggests having a discussion with jurisdictions, in an effort to:

  • Ensure a common understanding of this assembly
  • Determine how the assembly will be air sealed to control airflow to meet the air leakage requirements of the energy code.

One thing to note: jurisdictions throughout the state require that the two layers of sheetrock run continuously from the foundation to the roof deck, but not the entirety of the rest of the assembly.  The most conspicuous example is the interior drywall, which is always missing on the ventilated attic side of the party wall.

Challenge: How to Achieve 3 ACH50?

Now that a common understanding of the assembly has been achieved, it is time to determine how the assembly can be air sealed in order to meet the air leakage target of 3 ACH50 for the 2012 and 2015 IECC.  Most jurisdictions have not amended the requirement to meet this airtightness level, so pre-planning is crucial in order to be successful.

The clip that holds the framing off the two-hour party wall assembly creates a 1” gap that is connected directly to the outside at the front and back of the unit, as well as to the attic.  This is where the UL listing of the assembly comes into play. UL is an American safety consulting and certification company that provides the one or two-hour rating for fire-rated assemblies by testing them in a laboratory environment. The UL listing for these assemblies is often mixed up with code’s definition of the assembly, which creates confusion regarding what materials are allowed to be used to seal them.

UL often refers to fire-blocking materials.  Fire blocking materials are usually defined within the UL assembly and can be any one of the following:

  • 2” nominal lumber
  • Two thicknesses of 1” nominal lumber with broken lap joints
  • One thickness of 0.719” wood structural panel with joints backed by 0.719” wood structural panel
  • One thickness of 0.75” particleboard with joints backed by 0.75” particleboard
  • Gypsum board, including 1” DensGlass Ultra® Shaftliner and 5/8” DensArmor Plus drywall
  • Batts or blankets of mineral wool or fiberglass
  • Other approved materials installed in such a manner as to be securely retained in place shall be permitted as an acceptable fire block (Section 717.2.1, 2006 IBC). recap-of-ff-image_3

As some fire blocking materials are air barriers and some are not it important to choose a material that can stop the flow of air.  EnergyLogic has seen the most success when builders tackle fire blocking on each individual floor.

Application: The Picture Frame Method

When looking at the party wall assembly, envision a picture frame around the perimeter of the wall. All four sides need to be fire blocked.  The material of choice right now is the same 1” gypsum board used in the 2-hour rated assembly.  Install the 1” gypsum board in the 1”  gap between the interior of the unit and the outside at the front and back of the units, between floors, and to the attic.  Again, picture framing the party wall.

recap-of-ff-image_4

Depending on your foundation type, if you are standing on the first floor you will need to air-seal the two layers of gypsum and the bottom plate to the slab in the shaft wall, or address the rim joist connection in the basement or crawl space to the shaft wall. At the rim joist be sure sill seal has been installed between foundation and sill plate as it is your primary capillary break, then seal the sill plate to foundation, seal rim board to the sill plate, and seal the rim board to sub floor.  Pay special attention to any knockouts for foundation bolts.

Once the large 1” gap has been fire blocked with an air-impermeable material such as gypsum, seal the smaller gaps between the fire block and the shaft wall and the fire block and the framing.  A fire-rated caulk or expanding foam works for this. Following these steps, with careful attention to detail, should enable you to successfully achieve 3 ACH50.recap-of-ff-image_5

A few words of caution:

  • Ensure that the drywall lid is air-tight: duct boots and other penetrations need to be sealed. In addition, as required by ENERGY STAR, the drywall to top-plate should be sealed. (This is a requirement of code that is generally not enforced.)
  • Mechanicals can derail all good air-sealing intentions. Undampered ducts run to the exterior for combustion or ventilation air as well as atmospherically vented appliances. These combustion air ducts can ruin one’s ability to build a tight home that gains control and predictability of the airflow in the building.

Don’t Forget: Sound Reduction

Lastly, these assemblies should reduce sound transmission from dwelling unit to dwelling unit.  The party wall is assumed to be an adiabatic wall, i.e. there is no heat loss or gain through the wall between two conditioned spaces as the temperature is the same on each side. Therefore, the insulation is primarily installed to lower sound transmission.  The principles of sound reduction and heat flow are the same, so proper installation of the insulation in the framed cavity of the party wall is imperative.

NAIMA, the North American Insulation Manufacture Association, states that the installation of insulation in a party wall application should “comply with the manufacturers’ instructions including filling the entire stud cavity and cut to fit around outlets, junction boxes, and other irregularities in the cavity.”  In other words, the insulation in a common party wall should be installed to a RESNET, Grade 1.

The True Honor in Donating Time

During the week-long 2013 Habitat Jimmy & Rosalynn Carter Work Project, with Habitat For Humanity – Metro Denver,  EnergyLogic committed to sending members of our staff to work in the Globeville neighborhood.  The goal of the project was to complete 11 townhouses and rehabilitate 15 homes.

HFH Carter Visit

Mario, a metal worker, made a metal peace sign for each of us.

I was signed up for Wednesday, October 9th, which was the day that the Carters and honorary sponsors Garth Brooks and Trisha Yearwood were in Denver.  I was assigned to existing house #7 at the home of Mario and Phyllis Mora.  Our lively crew finished re-siding and painting the Mora’s garage that day.

I’ve been asked by many friends if I met the Carter’s.  Well, we sort of did get to meet them.  Mid-afternoon, we stopped work early to return to the park where we had met for the early morning  devotional ‘lesson’ from Jimmy Carter, and lunch.

Each ‘house’ gathered in a group with the homeowners at the park and when the Carters and Garth Brooks and his wife Trisha Yearwood arrived, they went from group to group for pictures.  Later, crossing the park, Garth Brooks said to me, “Take care.” I looked around to see if someone else was behind me!  They were all personable and funny and friendly.

It was exciting to see our former president, and to meet the honorary sponsors.  The biggest honor is to be a part of this project, and seeing that we all made a positive difference for the Mora Family, and for our community.

The Write Thing = The Right Thing

Very short missive this time.  I’ve been consciously working to get LinkedIn recommendations for those that I really know and value in my connections bucket.

An odd thing happened as I was writing.  If the touchy, feely freaks you out in any way, stop here…

In many cases, the folks that I’m recommending are in competitive or at least co-opetition relationships with me and EnergyLogic.  However, the very ACT of writing recommendations for these people resulted in my thinking positive increased positive thoughts about them.

In other words, there are a bunch of people that I have deep and genuine respect for.  It doesn’t mean that I always agree with them, but we are all generally working toward the same goals and objectives.  I value that tremendously.  It is one of the best things about this industry.

Who knew, saying positive things about people makes you feel even more positive about them.

Thanks to all who are on this path (even if I haven’t recommended you… yet).

ACI 2011: Thoughts about conferences in general

Another ACI has come and gone. This one, ACI 2011, was the biggest one yet.  That in and of itself tells you something important about our industry and the larger direction of things.  Beyond that however, here is what I took away from the conference.  To be fair, I didn’t attend very many sessions.  After a decade of attending ACI, I feel the quality of ACI sessions is beyond serious question.

I’m often asked by people relatively new to the industry where they should spend their conference travel dollars.  I almost always tell people that if they have the resources they should attend both RESNET and ACI.  If they can’t and they’re new to the field, they should probably pick ACI.  If they are primarily charged with running a company, organization or need to be involved in larger policy issues then RESNET is probably the better choice.  Now, this is just my opinion and I’m sure others would have a different perspective.  To be fair, both conferences have excellent technical content and both have pertinent and timely policy content.  One man’s perspective.

This year was like every other hear in that the content was excellent.  For any conference, after several years of attendance, you begin to feel as if you’ve little to gain.  A common conference complaint for the person who’s been to several years of the same show is that there isn’t advanced content for them.  True to some extent, but most people should be able to go to at least five years of a particular conference before they’ve tapped everything it has to offer.

Of course, that’s the time (or even before then) that you should be becoming part of the conference, more on that in my next post – Conferences – Taking it to the Next Level.

One of the primary reasons that we go to conferences of course is to see people that we rarely otherwise see.  Networking is not only fun and satisfying, it’s key to building a successful enterprise.  I just came across a great piece by Keith Ferrazzi called Conference Commando, on how to maximize your conference networking experience.  Not many of us are going to do everything that Keith suggests, but even doing a few things will help you get more out of your conference experience from a business perspective. I highly recommend reading it and implementing some of his suggestions.  Happy conferencing and good luck out there!
