Building exterior wall framing for additions, sheds, playhouses, or tiny houses is crucial in ensuring the structural integrity, insulation, and overall performance of a building. The permit process is usually simple, and stud spacing is typically 16 inches in exterior walls. 2- by 6-inch studs create a thicker wall, providing extra space for insulation, making a home more energy-efficient, comfortable, and soundproof. Exterior walls should be 254 mm thick, and a one-story building should not have an exterior wall under 245 mm.
The thickness of a stud wall can vary slightly based on factors such as timber thickness, plasterboard thickness, and sheathing thickness. For example, a home’s interior wall using 2×4 studs typically measures 4.5 inches thick, while exterior walls built with 2×6 studs have a 6-inch thickness. Masonry walls created with 2×4 and 2×6 framing look similar, but the sheathing must be 1⁄2 in. thick on the outside and 1⁄8 in. thick inside to span the 24-inch wall.
In most houses, interior walls are 4 1/2 inches thick, with a 2×4 stud (3 1/2″) and 1/2″ drywall on each side. Exterior wall thickness will vary depending on the building’s size and the type of studs used. Modern exterior walls are typically about 7.25 inches thick, with 2×4 framing, 1 inch exterior siding, and.25 inch interior drywall. Research has shown that exterior framed walls can be adequately supported by 2×6 studs spaced 24-inches on-center, reducing the number of studs in the wall.
For walls built with 2×6 studs, the minimum door jamb width required is 6 ½ inches.

Are 2×4 good for exterior walls?
Modern conventional home building typically uses 2×4 lumber for exterior walls, but 2×6 framing is a common upgrade required by some local building codes. This framing is 1. 5 times wider and is more expensive due to its higher wood content. Wider boards are used for rafters, floor and ceiling joists, and support columns.
Additionally, many wall supplies need to be upgraded at the new size, including extended window jambs, larger door jambs, extra insulation, and double top and bottom wall plates. The bottom plate typically consists of pressure-treated lumber on the bottom and conventional lumber on top. These additional costs add up, making it a major factor for more homeowners not opting for 2×6 framing.
What gauge metal studs for exterior walls?
Steel stud framing is a cost-effective alternative to wood stud framing due to its hollow design and minimal extra steel required. The cost of materials is determined by the steel gauge, with most load-bearing walls using 16 or 18-gauge studs and interior walls using 20 or 25-gauge metal studs. Contractors charge between $5 and $10 per square foot or $10 – $30 per linear foot for commercial projects. The larger the project, the lower the cost per unit.
Building type is rarely a factor in labor costs, but materials prices vary greatly due to special considerations like thicker steel gauge, multistory constructions, and thicker walls. Metal stud framing is more expensive than wood framing due to its durability, cost-effectiveness, and versatility. However, the cost of wood studs has decreased due to the increasing popularity of metal studs in new construction projects.
Can you have a 50mm stud wall?
The Stud Wall Kit 50mm is a soundproofing system designed to prevent sound transfer between rooms in homes. It is suitable for stud frames with a minimum depth of 50mm and includes high mass/density products, such as acoustic insulation slabs, Soundbreraker Bars, a 12. 5mm acoustic soundboard, and the 18mm Noisestop 1 Plus Panel. The panel features a 10kg mass-loaded vinyl acoustic membrane pre-bonded to the acoustic plasterboard. Acoustic sealant tubes are also included to ensure effective acoustic sealing.
The system includes acoustic insulation slabs, Soundbraker bars, a 12. 5mm soundboard laminated with 10kg mass-loaded vinyl, 12. 5mm Acoustic plasterboard, and acoustic sealant. The total wall area can be selected from the dropdown box at the top of the page.
What is the standard thickness of plaster on external wall?
Plastering thickness for external walls typically ranges from 15 mm to 20 mm, depending on the wall’s environmental exposure, material type, and desired aesthetic finish. The process involves a base and finishing coat, with a second coat applied depending on the surface type. For two-coat plaster, the total thickness should not exceed 20 mm, 15 mm for in situ concrete soffits, and 25 mm for three-coat plastering. The Indian Standard specifies the thickness for individual coats.
Should exterior walls be 2×4 or 2×6?
2×6 vs. 2×4 wall framing is generally suitable for small garages and sheds, as it is code compliant when bearing wall heights do not exceed 10 ft. Medeek Design typically specifies 2 x 4 studs @ 16″ o. c. spacing for small sheds and garages with building widths less than 16 feet. Larger structures are called out with 2 x 6 exterior studs @ 16″ o. c. unless otherwise specified. This type of framing is considered “conventional light framing” and is in prescriptive compliance with the building code.
Using 2 x 6 framing can increase the structural strength of the building significantly, with a significant difference in compressive strength, resistance to buckling, and lateral deflection. Additionally, 2 x 6 walls provide more space for insulation, resulting in less heat loss and smaller cooling and heating costs. Walls are also less drafty, improving the overall comfort level of the living space. Additionally, more space is available for utilities within framing, resulting in thicker walls with better soundproofing and less outside noise.
How thick is structural stud?
The article discusses the various stud sizes and metal thicknesses for structural applications, including web sizes, flange stud sizes, and metal thickness for interior and exterior curtain walls. The International Building Code requires interior walls to handle an interior pressure lateral load of at least 5 psf perpendicular to the wall, while walls spanning multiple floors with multiple exterior openings use loads of 7. 5 psf to 10 psf.
Clark Dietrich provides information on metal stud sizing, including the structural stud look up tool, which helps determine the appropriate stud for your desired wall height and thickness. The most common stud flange is 1-5/8″.
When deciding on sizing exterior curtain walls, key factors to consider include the weight of the wall, additional finishes, and other loads. The most common stud flange is 1-5/8″. The article also discusses the importance of considering the metal thickness and metal thickness for structural applications.
How thick is a 2×4 exterior wall?
The minimum exterior wall thickness is 3. 5 inches, inclusive of 2×4 framing, sheetrock, and exterior finish, with stucco and screen being 1/2 to 3/4 inches thick.
What is the thickness of exterior wall in MM?
In accordance with the bye-laws regulating the construction of buildings intended for residential use, external walls are required to be constructed using one of the following materials: 200mm blockwork, 230mm brickwork, or a 150mm reinforced concrete (RCC) wall. Conversely, internal walls may be constructed using either 100mm blockwork or 115mm brickwork.
How thick are exterior wall studs?
Studs are vertical load-bearing members used to support elements in walls and partitions. In exterior walls of one- and two-story buildings, studs are at least 2×4 inches, with a 16-inch spacing. In three-story buildings, studs in the bottom story are at least 3×4 or 2×6 inches, and may not exceed 16-inch spacing. They are arranged in multiples at corners and partition intersections for rigid attachment of sheathing, siding, and interior wall finish materials.
Nailing strips or metal clips may be used to back up interior finish at corners. A grademark identifies the species, grade, grading agency, and mill number, allowing the product to be traced to the mill of origin and establishing its structural properties. Most 2×4 dimension lumber is visually graded and marked with an ink stamp at the mill, ensuring the product’s strength for the application.
How thick should external walls be?
The thickness of exterior residential walls using ICFs depends on factors like the building’s design and location. Standard ICF walls require six inches of concrete, while areas susceptible to high winds require at least 8 inches. Engineering tables review these factors to determine the concrete core size and rebar layout. ICF reinforced concrete walls are superior to wood framed walls as shear walls.
How thick should a stud wall be?
A timber stud wall is typically comprised of studs measuring over 5 inches in thickness, with a width of 70 or 100mm. The construction comprises 5mm-thick plasterboard sheets and skim plaster finishes, typically made of plasterboard.

How can you eliminate thermal bridges in your new construction home? And, how do you build your home to maximize energy …
Double-stud 2×4 construction has become the ONLY build method my wife and I use these days. We’ve built a few homes and other buildings this way over the last fifteen years, and it’s both easy and cost-effective. Sure, the neighbors rolled their eyes, but they’re not laughing now. Our beautiful off-grid solar home requires a tiny fraction of the energy to heat, compared to the homes around us. We have twelve inch R-48 walls, R-68 overhead and R-36 underfoot (double Roxul batts). With our method, the outer wall is load bearing. The inner wall retains the insulation (blown-in cellulose), and supports the drywall. We use raised-heel trusses so the attic insulation doesn’t taper down over the walls. We clad the exterior in either Hardi composite cement siding or metal, over plywood. Never OBS, which is not an acceptable building material, in our opinions. We install triple-glazed windows, not top-of-the-line but better-quality vinyl windows we can afford. Right now it’s winter in central British Columbia. It’s minus 33C or minus 27F outside. Our home is heated with only a small wood cookstove and a bit of occasional solar gain via the south-facing windows. We light a fire in the morning, warm up the house, then let it go out. We light a smaller fire around dinner time, then let it go out as we head for bed. Our neighbors have huge wood heaters, which they load with armloads of wood. They all get up once or twice in the night to feed them. We use 1 1/4 cords of firewood per year versus their 5-8 cords.
