After the trusses were set and braced, we finished installing the rest of the blocks. Make sure that Temporary Dimensions are enabled. If trusses are stored horizontally, the blocking should be eight to ten foot centers to prevent lateral bending. Blocking between truss heels can function as this perimeter blocking of the roof diaphragm and becomes one of the connections from the roof diaphragm to the shear wall. Framing Details The 2009 International Residential Code, and to a greater extent its recently released 2012 version, require extensive blocking—perhaps even a shear wall detail—between trusses with heels higher than 15-1/4 inches to guard against truss uplift and seismic forces. Raised-heel trusses do not compress the attic insulation over the top plate, which compromises the insulation value. 2. Structural engineers may have questions regarding the prescriptive code requirements or the capacity of commonly used heel blocking to achieve a desired load transfer. By using longer OSB panels such as TallWall or Windstorm to cover the entire wall height and the raised heel, you can eliminate expensive blocking, while providing a continuous load path and lateral stability. Although 2×4 or 2×6 blocking is typically used, the new report outlines how structural wall sheathing can take its … If they are not, you can enable them by selecting View> Temporary Dimensions . I saw a great site that had photos of what can happen to trusses that aren’‘t properly braced during . July 7, 2017 Block the trem, loosen the strings, take a capo and back it off to minimal tension and slap it on the first fret (primarily for slot head tuners so strings stay in place), remove neck, adjust rod, reassemble and retune. Save design time, build time, and money with trusses built in long production runs. Framing Details The 2009 International Residential Code, and to a greater extent its recently released 2012 version, require extensive blocking—perhaps even a shear wall detail—between trusses with heels higher than 15-1/4 inches to guard against truss uplift and seismic forces. A new provision in the 2009 IRC, and carried through to more recent versions, is the use of blocking panels between roof trusses to connect the trusses to the braced wall panels below if the heel height is greater than 9¼". Heel blocking is for shear transfer. Metal Plate Connected Wood Trusses, HIB-91”, by permission of Truss Plate Institute, Inc. 4 STORAGE Trusses should be stored in a stable position to prevent toppling and/or shifting. In-Stock Trusses Built-to-Order Trusses. In high-wind or seismic areas, raised-heel trusses need special blocking and connectors. A construction system that uses raised-heel trusses in combination with exterior walls that are fully sheathed with plywood or OSB offers many ways to save and improves structural and energy performance, benefiting builder and homeowner alike. Less insulation for the entire ceiling system means savings on materials for the builder—and even with the reduced insulation, the home is still more energy-efficient and comfortable than one built with conventional trusses, and deeper insulation that is compressed at the eaves. —This article is from APA, The Engineered Wood Association. In traditional framing the roof is built stick by stick. When improved insulation is combined with efficient air sealing and adequate attic ventilation, a raised-heel truss roof reduces the pressure and temperature differences between the living and attic spaces, thereby cutting heat transfer and improving the efficiency of the HVAC system. We laid out for trusses on the double top plate and then pre-installed every other block so that we had instant stabilization for each truss where it sat on each exterior wall. Scissor truss slope differentials between top and bottom chords must be greater than or equal to 2/12 Maximum span to depth ratio is 24 for parallel chord roof trusses … Without the continuous sheathing, raised-heel trusses require blocking at truss ends above all braced wall panels. Blocking between rafters (or trusses) is used at the bearing points of rafters and ceiling joists to prevent lateral movement or rolling of the rafter. • The IRC requires blocking at the truss heels where there is a greater expectation of lateral loads causing rotation and displacement. The original purpose of a raised-heel truss was to allow roof lines to match up for improved curb appeal. 9:03. 1. Ventilation eave baffles, if needed, for air flow. Maximum span truss with un-triangulated heels 20’0”. For example, in colder climate zones where the energy code requires R49 ceiling insulation in attics, R38 insulation can instead be used, provided the truss heel is raised enough to prevent compression of the insulation. The extra height of a raised-heel truss roof provides additional space for uncompressed attic insulation and the full depth of insulation to be extended right to the outside of the top plate. Search Designs Custom Trusses. I was unclear on how those energy heels would work as part of the truss structure. 7 ULTRA-SPAN® TRUSS UPLIFT CONNECTION TO I-BEAM w/ 423HD14 1) Web or heel stiffener attached with (4) #10 SDS.

Roof Framing. Advanced options allows for the creation of sheathing, rake boards, fascia, heel blocking, roof returns (hip, full), battens, counter-battens and outlookers. Raised-heel trusses are most effective when used as part of a framing system that also includes continuous sheathing with wood structural panels on all exterior walls of the home. 7:55. = 2 vent holes 16 in. Other than Roof Pitch and Span, the most importand measurement need to match an existing roof is called the heel height. truss blocking for raised heel truss condition 1. The truss span is only ten feet, so (according to the Hawaii County building code) I do not need a professional design and stamp. 353 - Framing with Scissor Trusses . Ignore the vent holes in the blocking, I will provide additional options for venting in the near future. But sheathing with plywood or OSB can completely eliminate code-required blocking, saving time and expense provided that the requirements in Section R602.10.8.2 of the 2015 International Residential Code (IRC) are met. With this system, the wall-to-truss connection is greatly enhanced, resulting in superior overall load path, including better resistance to lateral forces like winds or seismic activity. The resulting lower HERS ratings make complying with the energy code easier and less costly. I do not like to rely on the truss not rolling over. Over time, this ice can force its way in under the shingles and cause water leaks. This heightened truss creates space that permits full-height, uncompressed insulation that … Savings aside, a home built with raised-heel trusses is simply more comfortable to live in. Continuous wood structural panel sheathing across top plates eliminates the need for blocking and minimizes air infiltration. Building Requirements with Raised Heel Trusses. or greater = 3 vent holes Install 2x4 plated roof trusses with slightly raised heel (provides additional insulation space over top of wall plus allows for strapping over bottom chord at top plate) on 24" centers. Raised-heel trusses improve energy efficiency, but the added distance between the roof sheathing and the top plates of the wall complicates the required lateral support, the APA said. A raised-heel truss is identical to a conventional truss except for one difference: it is raised higher, with a “heel” that extends up from the top of the wall and elevates the truss at the building’s edges. Currently this option is inactive/under construction. Standard trusses limit the amount of insulation that can be installed which reduces the efficiency of your building envelope or (depending on the Energy Code in your area), requires you to utilize foam insulation. Manufactured using high quality materials, pre-fabricated trusses typically enable the installation of roof framing in a single day. • Blocking is not typically installed in most interior parts of the country because the truss-to-bearing connections and the relatively close roof sheathing attachment is assumed to be sufficient to prevent any 3. Compressing insulation reduces its R-value but using raised-heel trusses provides additional space which means that the insulation doesn’t need to be compressed. Roof trusses combine rafters and attic floor joists into a modular triangular unit that replaces the traditional roof framing method. Without the continuous sheathing, raised-heel trusses require blocking at truss ends above all braced wall panels. To replicate trusses across a structure. Move the first truss into position using Temporary Dimensions. I will use a common truss design with plywood gussets, and the block raising the heel will be a 2x12, 3 1/2" high at the outer edge of the top plate. Multiple methods exist to increase the height of a heel. If the truss bundle is to be stored for more Overlapping the heels of raised-heel trusses with continuous plywood or OSB sheathing can cut costs. This will work better with the plywood gussets than a narrow upright. Finish materials such as gypsum board are typically applied to the bottom surface of ceiling joists or the bottom chord of a truss if the space below is to be occupied. (3) 2” screened holes for venting in each truss space (if needed) 2. Energy savings based on an analysis of homes located in climate zones 2–8. 3) Uplift values include 1.33 increase for wind or seismic. / Posted in: Builders, Framers.

The Ten most Important Fasteners for Installing Roof Sheathing, A raised-heel roof truss design can improve the efficacy of the. Trusses without raised heels will have a standard butt cut of 1/4 inches. It causes snow to melt instead of freezing into ice. Guitar Heel Blocks and End Blocks. Raised-heel trusses 9-1/4 to 15-1/4 inches in depth. Another good option is to install baffles 16 inches up the slope (or all the way up to near the ridge) to improve ventilation effectiveness. With trusses it is possible to prefabricate the pieces needed into modular frames that can be installed every 24 inches to frame a roof with much less time and trouble. Crushing at the heel - Sometimes the forces transferred through the wood into the bearing wall are enough to cause the wood to crush over time unless a bearing block is used. 3) Uplift values include 1.33 increase for wind or seismic. More importantly, the raised heel provides the opportunity to increase energy efficiency to meet new Energy Code requirements. Improved ceiling insulation eliminates the cold spots at the top of exterior walls that conventional trusses create, resulting in a more stable temperature and a more comfortable home. or greater = 3 vent holes Overlapping the truss heels with continuous plywood or OSB sheathing creates a stronger building envelope by enhancing the connection between the wall and roof. Other than Roof Pitch and Span, the most importand measurement need to match an existing roof is called the heel height. By using longer OSB panels such as TallWall or Windstorm to cover the entire wall height and the raised heel, you can eliminate expensive blocking, while providing a continuous load path and lateral stability. No further increase is permitted. We won't send you spam and only send at most two updates per month. While solid wood blocking can be used, this is an opportunity for flat top truss blocking, furthering the use of components. I always show 2x blocking between trusses at the bearing wall or beam regardless of truss heel height. If trusses are stored horizontally, the blocking should be eight to ten foot centers to prevent lateral bending. Building codes require extensive blocking on raised-heel trusses higher than 15 ¼ inches to prevent uplift during inclement weather and create a stable structure. Get all the latest news and industry tips straight from Norbord delivered to your email.

Improved ventilation can be achieved with the installation of not only the appropriately-sized soffit vent (or continuous eave vent) but also a ride vent along the roof’s peak. It’s not surprising that four out of five modern homes are built with pre-fabricated trusses as they offer many advantages; a more uniform pitch and size, increased spans mean fewer internal load-bearing walls and they use less installation time and labor. Ignore the vent holes in the blocking, I will provide additional options for venting in the near future. Raised Heel This option allows a raised or energy heel truss. Figure 1: Shear forces acting on heel block The Building Designer may not assume that prescriptive heel blocking will perform adequately as perimeter blocking for the ; Click the Select Objects button, then click on the truss to select it. In some jurisdictions, eaves blocking—2x blocking with a depth that matches the heel height—must be installed between trusses at the outside edge of the wall top plate to resist wind and seismic forces. Trusses will be toe-nailed or screwed to the top plate initially to hold them in place during installation. Where joists are perpendicular to a braced wall panel above or below, a rim joist, band joist or blocking shall be provided along the entire length of the braced wall panel in accordance with Figure R602.10.8(1). One of the biggest benefits of raised-heel trusses is a lower Home Energy Rating (HERS) index for the home, which means lower utility bills for the customer and easier code compliance (under Section R406, Energy Rating Index Compliance Alternative, of the 2015 International Energy Conservation Code, or IECC). It causes snow to melt instead of freezing into ice. The engineered stamped truss certificate will indicate if a particular truss requires bearing blocks. = 1 vent hole < 16 in. Roof Trusses Do not break truss triangulation by removing webs. Related Videos. Finish materials such as gypsum board are typically applied to the bottom surface of ceiling joists or the bottom chord of a truss if the space below is to be occupied. Advanced options allows for the creation of sheathing, rake boards, fascia, heel blocking, roof returns (hip, full), battens, counter-battens and outlookers. All other blocking between trusses can be vent blocking with 1" air space above the block for venting, or can be drilled blocking with vent holes. Raised-heel trusses are installed the same as conventional trusses. For uplifts not resulting from wind or seismic, reduce capacities to 75% of values shown. 2) Minimum screw spacing = 9/16". Looks like the wall sheathing overlaps the energy heel above the top plate. While solid wood blocking can be used, this is an opportunity for flat top truss blocking, furthering the use of components.

Using raised-heel trusses allows you to increase the amount of cheaper insulation used such as blown cellulose or fiberglass batts. For trusses perpendicular to the wall, blocking panels or full depth rim board blocking must be used to transfer forces from the roof/floor sheathing to the top plate of the braced wall panel, and to prevent the floor trusses from rotating. Raised-heel trusses differ from their conventional truss counterparts in that they are fitted with a heel where the bottom chord intersects with the perimeter wall plate which raises the top chord. Basic wind speeds of 110 mph or less (Ultimate design wind speed, VULT, of 140 mph or less), Seismic Design Category A, B, or C for detached one- and two-family dwellings, Seismic Design Category A or B for townhouses, Raised-heel trusses 9-1/4 to 15-1/4 inches in depth. A raised-heel truss is identical to a conventional truss except for one difference: it is raised higher, with a “heel” that extends up from the top of the wall and elevates the truss at the building’s edges. 3:46. A wall system combining raised-heel trusses with overlapping continuous wood structural panel sheathing has a hidden structural advantage over conventional wall-to-truss connections. Getting the house under roof sooner can help mitigate moisture issues. When builders use these trusses, the energy code allows for use of less insulation for the entire ceiling system. The email you entered isn't valid. Depending on the heel height raised heel trusses will require a wedge, slider or vertical web with strut. #66 – TRUSS BLOCKING AT RAISED HEEL CONDITIONS OR STRUCTURAL FASCIA AND SOFFIT 1.
