    R602.3.1 Stud size, height and spacing. o.c. Exceptions: 1. Building scientists suggest that builders should consider the “whole-wall” R-value as opposed to the center-of-cavity or rated R-value of the insulation. Utility grade studs shall not be spaced more than 16 inches (406 mm) on center, shall not support morethanaroofandceiling,andshallnotexceed8 feet (2438 mm) in height for exterior walls and Stud spacing can also affect cost savings. Footnote 25) In Climate Zones 6 - 8, a minimum stud spacing of 16 in. is permitted to be used with 2x6 framing if ≥ R-20.0 wall cavity insulation is achieved. While we continually update our database, links may have changed since posting. Align windows and doors with this two-foot stud spacing to reduce the number of extra king studs needed. Where the number of required jack studs equals one, the header is permitted to be supported by an approved framing anchor attached to the full-height wall stud and to the header. Exhibit 1, Item 1) Certified under the ENERGY STAR Qualified Homes Program or the ENERGY STAR Multifamily New Construction Program. the Original wall 14x14,so is the wall i will be building. In nonbearing exterior walls, 2x6 studs spaced at 24 in. The wind loads to which they will be subjected. 2x4 vs 2x6 framing is a valid question. The construction supervisor should ensure that framing crews are knowledgeable of or trained in advanced framing techniques. ENERGY STAR Certified Homes, Version 3/3.1 (Rev. Table 2 diagrams the allowances for the maximum stud spacing based on the number of supported stories for load-bearing walls. The Compliance tab contains both program and code information. Cutting, notching and boring of nominal 2x4 (1-1/2" x 3-1/2") and 2x6 (1-1/2" x 5-1/2") LP LSL and LP LVL wall studs used in prescriptive wall framing is permitted in accordance with sections 2308.9.10 and 2308.9.11 of the IBC and section R602.6 of the International Residential Code (IRC). Advanced framing techniques should be specified in the framer’s contract. While we continually update our database, links may have changed since posting. for 2x6 framing.25. Detailed framing elevations should be prepared after confirming that these advanced framing techniques are permitted by code in the local jurisdiction. Code language is excerpted and summarized below. For example, 16-foot, 3-1/2-inch metal studs spaced every 16 feet inside a wall provide nearly twice the support as the same size studs spaced every 24 feet within the wall. on center (upper stories are allowed to be at 24 in. Guide describing details that serve as a visual reference for each of the line items in the Thermal Enclosure System Rater Checklist. 2. Metal T-bracing nailed to studs saves on the labor cost of 1x4 let-in bracing 2x4 or 2x6 stud Saw kerf for T-brace K-brace when window or door is near corner 1x4 let-in brace notched into wall studs • Use full foam sheathing over other ap-proved wall bracing (e.g., metal strap-ping, let-in wood 1x ’ s). Align rafters, wall studs, and floor joists so that the load is transferred and adequately supported to allow installation of single top plates. When other advanced framing measures were added, like switching to single top plates, 24-inch spacing of interior walls, and open headers, lumber costs were reduced $1,117 (Baczek, Yost, and Finegan 2002). Construct framed walls using advanced framing details like using the minimum amount of wall studs permitted by code to reduce thermal bridging and allow more space for insulation. This topic is not specifically addressed in the IRC. This 2x6, 24-inch on-center stud spacing is one of many components of advanced wall framing that reduce costs and provide materials and energy savings. Research has shown exterior framed walls can be adequately supported by 2x6 studs spaced 24-inches on-center. This relationship is only approximate because the improvement will not be the same at every frequency and depends on the source of the sound. Because Table R602.3.1 addresses stud heights above 10 ft, the implication is that the default maximum stud height is 10 ft. for 2x4 framing in all Climate Zones and, in CZ 6-8, 24 in. Techniques for installing 24-inch on-center exterior and interior wall framing and single top plates are described below. 09), Thermal Enclosure System.

Detailed guide to advanced framing, a system of construction framing techniques designed to optimize material usage and increase energy efficiency. In some cases, local authorities may waive this if the exterior framing uses 2 x 6 … We did a project last year and we had to build a 20′ high fire wall. As wall height increases, so does the need for a beefier structure. For exact code language, refer to the applicable code, which may require purchase from the publisher. One 2″ x 4″ x 8′ #2 Spruce Pine Stud is good for about 3000 lbs of compressive load, when held in place by drywall. 1. Reducing the number of studs in the walls by one-third also reduces labor costs in terms of the time it takes to handle, cut, install, drill through, and attach to studs. There's a small extra labor fee to work with the studs. The size, height and spacing of studs shall be in accordance with Table R602.3.1. Minimum 2x6 studs at maximum 16” (406 mm) on centre 4. Also, cost savings will be realized because the details will help gain building official approval, improve accuracy for materials purchasing, clarify instructions for the lead framer, assist in training subs, and greatly improve the chances that the specified measure will actually be implemented (Baczek, Yost, and Finegan 2002). These stud tables are intended for determining the feasibility of using tall wood stud walls for a given application. Walls that tall tend to get wavy if framed with 4" lumber. In some jurisdictions, particularly in hurricane zones, 16-inch on-center is the maximum stud spacing allowed; check with local code officials. It had 3 layers of 5/8″ firecode drywall on each side!! A nominal 4 in. Notching bearing walls cannot exceed 25% the width and 40% in non-load bearing walls. Privacy. on center). 3. We used 18 guage 6″ studs for that. In the same simulation, researchers found that the calculated whole-wall R value of a 2x6 24-inch on-center wall insulated with R-19 batts, was R-15.2, or 80% of R-19 (Baczek, Yost, and Finegan 2002). Building America Solution Center is a resource of the Department of Energy's Building Technologies Office. Got to love fire rated walls . Stud Tables Scope This section features stud tables for lumber studs and proprietary engineered wood studs. Read more Read less, Simulated tones developed by Veneklasen Associates. Notches in bearing wall studs may not exceed 25 percent of the stud’s width. The energy savings is accounted for by two factors – the thicker wall enables wall insulation to be upgraded from R-13 to R-19 and less studs mean less thermal bridging. Report describing approaches to using less wood in home building that minimize waste. (So, it needs 9-foot studs.) Exceptions: Utility grade studs shall not be spaced more than 16 inches (406 mm) on center, shall not support more than a roof and ceiling, and shall not exceed 8 feet (2438 mm) in height for exterior walls and load-bearing walls or 10 feet (3048 mm) for interior nonload-bearing walls. Web Policies | When the entire home is designed on a 2-foot grid from roof rafters to wall framing to floor joists, sheet good and lumber waste are greatly reduced. All else being equal, a wall with a rating of STC 60 will result in sound levels that are on the order of 10 dB lower than a wall with a rating of STC 50. we have and are using flitch plates bolted between 2 2x6 studs for each king of the header in a 14' wide opening 16' tall. This is not intended to be a simulation of any particular wall or source; subjective reaction to noise is dependent on many factors (such as background noise level, time of day, frequency of occurrence, spectral characteristics) that cannot be adequately simulated in an on-line demonstration. Table 2 diagrams the allowances for the maximum stud spacing based on the number of supported stories for load-bearing walls. Framing on a two-foot also saves money by reducing material waste. Advanced framing details should be specified in the construction plans (i.e., framing elevations should be provided) and reviewed with framers. Advanced framing details include using the minimum amount of wall studs permitted by code. A Sound Transmission Class or STC rating provides a rough estimate of the reduction in sound level across a wall from one space into another. For me, it isn't a matter of code. For walls up to 10' in height, 2x4 and 2x6 1.3E TimberStrand® LSL studs may be conventionally specified per the limitations described on this page. For frame walls that are more than 20 feet in height, fasten the studs to the top plate and sole plate using fastening or an approved fastener that is capable of supporting at least 450 pounds. Exterior Stud Walls: 2x6 16" O.C., 5/8" Gypsum, Insulated, 3/8" Siding 12 FRAME WALLS Exterior Stud Walls With Brick Veneer 48 Windows, Glass, Frame, Sash. Where the roof span exceeds 32 feet, the wall studs shall be increased to 2x6 or the studs shall be designed in accordance with accepted engineering practice. The studs for these framing systems must be able to withstand: The weight of the cladding material (metal, stone, tile, etc.). Tall Walls. The size, height and spacing of studs shall be in accordance with Table R602.3.(5).. Reduced Thermal Bridging. This house is being built with advanced framing techniques including 2x6 24-inch on-center wall … the overall wall height is just shy of 18'; 2x6 studs will be used throughout the rest of the 2 story wall. Maximum total height = 24 ft (7.3 m) 2. Drilling holes can’t be more than 60% the width if 5/8” is left on each side of hole. Connect top-plates using either a metal plate or a wood splice. Information sheet about advanced wall framing. So, let’s take a look at the numbers… This house will use approximately 580 studs. In one study employing several advanced framing techniques, such as 2x6 24-inch on-center wall framing, 24-inch on-center floor joist and rafter spacing, 2x4 24-inch on-center interior framing, 2-stud corners, open and insulated headers, reduced studs around windows and doors, and single top plates, all of the measures combined contributed to energy savings of 13% over standard framing but this single measure alone  - switching from 2x4 16-inch on-center to 2x6 24-inch on-center framing– accounted for energy savings of 11% (Lstiburek and Grin 2010). i have to build a wall that was removed a few years ago. The ’03 edition has been revised to 3.4.3e Minimum stud spacing of 16 in. For this discussion, we are going to use a 3,200 square foot home with a wall height of 9 feet. Brick veneer wall assemblies with wood stud backing routinely attain fire ratings of up to 2 hr. Report investigating implementation of advanced framing in both production and prototype built homes built in a variety of climate regions across the USA. This wider spacing reduces the number of studs in the wall, thus reducing thermal resistance and increase the amount of space available for insulation. If bearing wall height is greater than 10 ft. the building code requires that they be engineered to verify their load capacity to resist bending of the studs due to out-of-plane loads. For an 8-foot wall, don’t purchase standard precut 92.5-inch studs, purchase 8-foot (96-inch) studs and cut them to 94 inches (. An architect might call for two-by-six wall studs instead of two-by-four studs when wall height exceeds 9 feet. Adding more studs than necessary wastes lumber and reduces the wall’s thermal resistance because the lumber blocks cavity space that could be filled with insulation and because each stud represents a thermal bridge that can transfer heat between the interior and exterior of the building. This house requires 4,276 square feet of framing with porches and patios, which is approximately 580 studs. Design for wall lengths and heights, window and door sizes, etc., on a 2-foot grid, wherever possible to reduce framing members in walls and to reduce lumber and materials waste. in Climate Zones 6 - 8 shall have ≥ R-20.0 wall cavity insulation installed regardless of any framing plan or alternative equivalent total UA calculation. Non-structural connectors can be installed for non-load-bearing interior walls. This is intended to help users experience the changes interactively. The following authors and organizations contributed to the content in this Guide. my question is what is the maximum height for a 2x4 stud non load bearing wall? Most sheet goods (plywood, OSB, foam insulation) come in 4x8-foot sheets. Exhibit 1 Mandatory Requirements. Attach gypsum board to full height on both sides of studs with Type S bugle-head drywall screws (Type S-12 for 20-gauge studs) This topic is not specifically addressed in the IECC. Other techniques are described in other resource guides: see Insulated Corners, which explains how to construct corners with 2 studs instead of 3 studs to permit more insulation, Insulated Headers for tips on how and when to build open and insulated headers over windows and doors, Minimal Framing at Doors/Windows for efficient framing around doors and windows, and Insulated Interior/Exterior Wall Intersections for ways to reduce framing and add insulation where interior walls intersect exterior walls. Tall Walls Workbook 3 2. 1½ : 8 height limit 5½” (2 6) M H i ht 22’ 6” between blocking… 5½” (2x6) Max Height: 22’-7¼” (2x8) Max Height: 30’ Stud or column in a sheathedStud or column in a sheathed Stud or column in a sheathed wall is braced against buckling in this direction. Load-bearing walls may be designed in a manner similar to that for columns but including the design requirements for non-load-bearing walls. Access to some references may require purchase from the publisher. In one study, a 2x4 16-inch on-center wall was insulated with batts labeled R-13, but researchers calculated the actual whole-wall insulation value of the wall at R-9.4 (or 72% of R-13) when the thermal conductivity of the framing, windows, and doors are taken into account. 3.
