Typical Timber Frame Wall Construction

The typical timber frame wall construction is a very popular method of building a house. It is used in many different kinds of construction, including houses and apartments. This type of wall usually consists of studs that are placed on the floor joists and plates that are nailed over the studs. The gaps between these members are filled with insulation or sheathing materials such as plywood or OSB boards. Then, metal plates called siding sheets are attached to both sides of each vertical stud after which windows and doors can be installed into them for easy access.

Timber frame wall construction is one of the most popular construction methods in the United States. It’s used for residential and commercial buildings, as well as individual homes. The construction method is considered to be environmentally friendly and energy efficient.

Timber frame walls are usually made with a combination of wood and steel beams. These walls are constructed by attaching vertical and horizontal beams together to create structural support for the building’s roof.

Wooden beams provide the strength and rigidity needed to support heavy loads while steel beams provide additional support for wind loads and earthquakes. Timber frame walls are usually made with dimensional lumber that includes 2x4s and 2x6s.

The wood used in these walls must be able to withstand fire or other damage that could occur if there’s an accident such as a fire or earthquake.

Timber frame walls are built using a timber frame and load-bearing, load-transferring members. The simplest and most common type of timber frame wall is one that uses horizontal beams called sole plates as the base of the wall, with vertical posts (also called studs) running straight up from the sole plate. These studs are attached to the sole plate by means of nails or screws at intervals of around 400 mm.

In addition to these studs, other horizontal members such as purlins (horizontal slats) can be added to support roofing materials in a structure. A timber frame wall is considered complete once all these elements have been added together.

What is Timber Frame Wall Construction

Timber frame wall construction is a type of house building that uses timber frames to support the walls of a home. Timber frames are constructed from large pieces of wood and are designed to stand up on their own, eliminating the need for load-bearing walls. Timber frame houses are built in three main phases:

  • Foundation – The first phase involves digging out a hole for the foundation and then pouring concrete into it. Afterward, you’ll place rebar into your foundation so that it can hold up the weight of your house.
  • Flooring – In this phase, you’ll put down OSB (oriented strand board) flooring or plywood overtop your foundation and secure it with nails or screws as needed. This will provide a solid base for placing your exterior walls and roof on top later on down the line.
  • Exterior Walls – In this final phase before moving inside, workers will build all four sides by attaching studs (vertical pieces) onto each side one after another like bricks stacked together vertically until all sides have been completed successfully; making sure each one matches evenly with its neighbors both vertically as well as horizontally in order for everything else below such as insulation to fit correctly too; which means two distinct layers at least between them both: First being exterior sidings such as cedar shakes or brick veneer panels along with other decorative features.

What is Timber Frame Wall Construction used for

Timber frame wall construction is used for residential, commercial, agricultural, and industrial buildings. It is used to build homes and other types of buildings that are designed to last long periods of time without needing significant maintenance.

Advantages of Typical Timber Frame Wall Construction

First, it is strong. In fact, a timber framed wall can support up to six times its own weight without requiring any additional support. This makes it an excellent choice for large, open spaces. Second, it’s durable and long-lasting; you won’t have to worry about water damage or mold as with sheetrock walls because the wood will not absorb moisture as sheetrock does. Thirdly, since the wall is made of solid lumber it has very good insulation properties; this will help keep your home cool during summer months and warm during winter months reducing energy costs. Lastly, timber framing is easy to construct compared with other materials such as concrete block or stone masonry that require specialized skill sets before construction can begin.

Disadvantages of Typical Timber Frame Wall Construction

Timber frame walls have a few characteristics that can make them less than ideal for some conditions. These include:

  • Timber frame wall construction is more expensive than other types of wall construction.
  • The timber frame walls are not suitable for all locations, such as where earthquakes and hurricanes occur.
  • Installing timber frame walls requires more skill and experience than installing masonry or steel studs.
  • It takes longer to install timber frames compared to other types of wall construction because each piece must be fitted together before it can be attached to the foundation or another piece of the structure.

Parts of Typical Timber Frame Wall Construction

For timber frame walls, each of these components is individually cut and assembled.

  • Studs: The studs are the vertical pieces that make up the frame. They’re typically made of 2 x 4s or 2 x 6’s and maybe single-sided or double-sided.
  • Plate: The plate is a horizontal piece that sits at the top of each stud it provides stability to prevent sagging and helps distribute weight evenly across all framing members. Purlins can also be used as plates if they’re part of an engineered system.
  • Cavity insulation: Insulating layer placed between walls before sheathing (the board covering) is applied; usually consists of fiberglass batting or polystyrene foam in loose-fill form (see below). Most often done with blown-in cellulose insulation; other options include blowing in loose-fill mineral wool batts or spraying foam insulation into cavities through small holes drilled into wall framing members by licensed professionals who do this for a living.

Floor joists

One of the most important elements in framing a timber frame is the floor joist. It’s not, however, always obvious what exactly a floor joist is or how it works. So let’s take a few minutes and go over some basics.

The first thing you should know is that there are two different ways to lay out your floors: along the lengthwise axis and across the widthwise axis of your building (or “in plan”).

To begin with, let’s look at how floor joists are arranged when you build along their lengthwise axis. To do so, we will take as an example a 16′ x 20′ house with 12″ on center timber frame walls (i.e., 2′ x 4′). In this scenario there would be 28 individual 16′ long joists running from wall to wall across each level of our home (or “floor”). Each one of these joists would have its own dedicated load-bearing capacity; for instance, if we were using pressure-treated lumber for our frames then it would be possible for each individual 2×4 to bear up under around 1 ton per linear foot – meaning that all together those 28 2×4 studs could support 28 tons worth of weight (“dead load”). We must also consider live loads though; when calculating how much weight each floor beam can safely hold without buckling you must also account for any people currently occupying those rooms as well as any furniture they may place upon them which might add additional stressors onto this total figure.

Floor decking

The floor decking is a ¾-inch plywood or oriented strand board (OSB) subfloor that serves as the base for the rest of the floor system. It provides a smooth, flat, and level surface for attaching the subflooring and finishing the flooring.

The floor decking sheet is installed over sheathing on top of the sill plate, which is in turn attached to concrete piers or timber posts. The joist hangers are then inserted over nails driven into these piers or posts through holes in joist hanger plates.

The next layer consists of joists spanning 16 inches in the center with 2x12s running perpendicular to this layer to support headers above openings such as doors and windows. Beams run parallel to this layer at diagonals between gable walls; they provide strength against lateral pressure from wind loads acting on outside walls due to their unique configuration: each bears outward against one wall while bearing inward against another wall at its opposite end where it forms part of an internal corner joint between two walls meeting at right angles (eaves).


The subflooring layer is the bottommost layer of material that is installed under the flooring. The subflooring can be made of plywood or OSB (oriented strand board). The purpose of this layer is twofold: it provides a smooth surface for the flooring to be installed on, and it keeps everything from settling over time.

The subfloor should always be at least 1″ above the finished floor height so that you have room for expansion if your building is not perfectly level, as well as for any moisture that seeps into the walls from below ground level (if this happens).

Liner panels

Liner panels are used to reduce the amount of air that gets between the studs and sheathing. They’re typically made of plywood or OSB (oriented strand board), which is similar to plywood but made from smaller pieces of wood, giving a stronger bond when glued together. Liner panels are installed on both sides of the wall.

In addition to reducing air leakage, liner panels help keep moisture from pushing behind your exterior siding or trim by acting as a barrier against rainwater and snow melt.* They also act as an insulating layer for heat loss in wintertime* and help prevent condensation in walls constructed using cold-formed steel studs.

Studs and Plate

  • Studs are vertical members in timber frame walls.
  • Plates are horizontal members that run perpendicular to the studs.

There are a few different types of plate, but they all have one thing in common: they’re all 2×4 or 2×6 lumber (or solid wood or engineered wood).

Cavity insulation

The next layer is the insulated sheathing. This is made up of a combination of wood, foam, and plasterboard insulation. The primary purpose of this layer is to provide structural stability, as well as thermal and acoustic insulation for the wall assembly.

To further improve the insulation properties of this layer, it should be lined with 2 or 3 inches (50mm-75mm) of rigid plastic sheeting known as ‘liner panels’. These liner panels prevent moisture from getting into the cavity and cause it to bypass through or around any voids in your timber frame wall construction as outlined below.

A final finish can then be applied on top if required – typically lime plasters will be used in most cases but these can also be replaced with acrylic render systems which offer more flexibility when finishing external surfaces

Insulated sheathing

The insulated sheathing is a material that is used to improve the thermal performance of the wall. It can be made from fiberglass, polystyrene, or polyisocyanurate. The insulated sheathing is attached directly to the studs or attached to a gypsum board for fire protection. The thickness of insulated sheathing will depend on what it’s being used for and how much air tightness you want in your home.

Wind and rain barrier

Here’s a primer on the two most common types of waterproofing:

  • Waterproofing is the process of preventing water from penetrating through a wall assembly.
  • Weatherproofing is the process of preventing wind and rain from entering a building.

It’s important to note that both waterproofing and weatherproofing are important, but there is also a difference between them: Waterproofing prevents water from getting in; weatherproofing prevents wind and rain from getting in.

Materials needed for Typical Timber Frame Wall Construction

  • wooden studs are the horizontal and vertical timbers that form the framework of a wall, creating cavities between them. They are usually made out of softwood such as spruce, pine, or fir. The size can vary depending on whether it’s a primary or secondary stud. Primary timber has a large face area and is used to support heavier loads like structural loads on floors or roofs. Secondary timbers are used primarily for partition walls and don’t need to be as strong because they aren’t supporting any other load-bearing components such as floors or roofs. If you look at your typical wooden studs you’ll see that they have three sides (top side, bottom side which is usually wider than the top side), one end grain face which has many knots or holes from where the tree grew and its growth rings (this face will be covered by insulation later) and an open end on each end where there’s no knotting but instead rather straight grain lines running down along this third side – this helps prevent splitting when nailing into it with nails which would otherwise happen more often if there was no straight line running through this open area without any knots present since nailing into wood tends to split off pieces if it hits any knots while being hammered;
  • If using traditional construction methods then all wood used should ideally come from sustainable sources such as forests certified according to PEFC standards where possible.

Tools needed for Typical Timber Frame Wall Construction

You will need the following tools for typical timber frame wall construction:

  • Hammer. A hammer with a claw on the back is ideal for removing nails from framing members.
  • Sledgehammer. You may have to use a sledgehammer or other heavy, solid striking tool to drive stakes into the ground for temporary bracing during the construction of your timber frame wall.
  • Tape measure and level. Use these tools to ensure that you are building each panel within tolerances outlined in your plans or from an existing framework that was built by someone else at some point in time (e.g., historical precedent). If you choose not to follow these guidelines and do not have access to them yourself, then your timber frame wall may be slightly out of plumb when it’s finished which means it won’t sit very straight up against its neighbors (or maybe even fall down).

Cost of Typical Timber Frame Wall Construction

The cost of typical timber frame wall construction is the sum of the cost of materials and labor. The overall cost will vary depending on whether you plan to hire a contractor or do it yourself.

Typically, a contractor would charge $10-$15 per square foot for labor costs (not including material costs). The total amount that you can expect to spend on your timber frame home will depend on how large it is and what materials you choose, but using this rough estimate as an example: If you have an average-sized house at 1,500 square feet then the overall costs would be $17,000-$22,500. That’s not too shabby considering a similar size conventional home built with drywall might run about $40K.

The material cost of Typical Timber Frame Wall Construction

The materials you need to build a typical timber frame wall are mostly straightforward and available from any home improvement store. You can also shop online for them, but make sure you’re getting the best deal by comparing prices across multiple websites. Here’s a list of common tools and materials used in typical timber frame wall construction:

  • Wood frame materials (lumber)
  • Nails or screws (for fastening wood pieces together)
  • Mortar (for filling cracks between large pieces of wood and small gaps between smaller pieces)

The labor cost of Typical Timber Frame Wall Construction

The cost of labor for Typical Timber Frame Wall Construction is high because it requires skilled workers to do the job. The labor costs of Typical Timber Frame Wall Construction can vary depending on whether you have a professional crew or you hire amateur laborers. The labor cost of Typical Timber Frame Wall Construction is fixed and does not change, even if you are willing to pay more money.

Benefits of Typical Timber Frame Wall Construction

  • Low Cost

The cost of this type of wall is about half that of concrete block and masonry walls. This is due to the lack of mortar required for joining the timbers together, which reduces labor costs and time spent on construction. Also, wood framing can be more efficient than brick or masonry because it has greater insulation value (especially when compared to concrete blocks).

  • Easy To Build

Timber framing is easier to build than other types of walls because it uses prefabricated headers, girt beams, and braces that are bolted together with connections that don’t require mortar or plastering skills (unlike masonry). In addition, many contractors have extensive experience building timber frame homes because they’ve been building them since colonial times. They know all the tricks needed for an efficient installation process such as installing insulation layer after layer while avoiding excessive dust etc.

Maintenance tips for Typical Timber Frame Wall Construction

The best way to ensure your timber frame wall lasts a lifetime is to keep it in good condition.

Regularly inspect the timber frame wall for signs of rot and decay. Repair any damage immediately and consult with an experienced builder if you’re unsure how to do this on your own. Remove any mold growth from the timber frame wall before it becomes a problem, as it can spread quickly. Clean the timber frame regularly using a mild detergent solution, then dry completely with a soft cloth or chamois leather (never use soap). Protect your timber frame from water damage by covering it when washing windows or cleaning outside soffits, eaves, and gutters; also avoid exposing it to rain during construction projects on neighboring properties that might cause runoff onto yours (e.g., roof repairs). If you often need access above doors or windows but don’t want them propped open permanently because you’re worried about security issues such as theft which could occur if someone broke into your property while you were away consider installing either an exterior doorstop (one part fits inside the doorjamb while another part goes outside) so that when closed properly this type of product prevents both openings inward or outward movement due its design which allows only one direction at once; alternatively, there are inexpensive acrylic blocks available online which function similarly but aren’t suitable for outdoor use due their fragility should they fall off scaffolding etcetera

In Conclusion

Timber frame walls are a great way to build your dream home. Not only do they have a lot of character, but they also have longevity and durability. When done properly, they’re very strong and can last for generations if properly maintained.
