TIMBER FRAME - Timber species - timber framing techniques

Traditional mortise-and-tenon joinery is at the heart of every Timberpeg design. The centuries old technique of joining timbers secured with oak pegs is the primary fastening system. Housed tenon, bird-mouth, shouldered, fork & tongue, dovetail, tusk tenon, and splines are but a few of the more common joinery techniques used. Below are some more details about what we provide in a TIMBERPEG home and our timber frame package.

Our vast experience with various species tells us that frame stability is of paramount importance. Therefore, we have chosen eastern white pine and Douglas fir as our primary materials to fashion our timber frames. High quality Douglas fir and eastern white pine are the most stable green materials we have ever worked with, offering our customers a superior frame that will endure for generations. Other species are available upon request. Species we support are as follows:

  •     The finest grades of Douglas fir, (available FSC® Certified)
  •     #2 Eastern White Pine, Boxed Heart; (#1 is available in limited quantities. Available FSC Certified)
  •     Port Orford Cedar, Available Upon Request
  •     Reclaimed Douglas Fir and Other Species, Available Upon Request

Timberpeg designs and manufactures both "Traditional" and "Bent" style timber frame systems. Occasionally, we incorporate both styles into the same structure. Only after a careful analysis of your space requirements can we offer you our opinion as to which style will be most effective for your particular need and budget.

Traditional Timber Framing - Traditional timber framing uses common rafters supported by a principal ridge beam or series of principal purlins. The vertical support posts can be placed virtually anywhere along the support line, which allows for greater flexibility during design than the bent style allows.

Bent Style Timber Framing - Bent-style timber framing uses principal rafters with purlins running parallel with the ridge of the building. Each bent is assembled on the first floor deck and raised into place, often with the help of a crane. Purlins are then inserted to link one bent to the adjacent bent.

Second, Third and Loft Floor Systems

A typical Timberpeg floor system in our timber frame package is comprised of timber floor joists 4' o.c. with 2" x 8" western white spruce tongue-and-groove decking with v-joint placed down. Electrical wiring can be embedded into the floor joist or deck boards as needed. An alternative approach is to frame a conventional open floor over the top of the timber floor joist. This creates a cavity in which you may run electrical and mechanical ductwork. Timberpeg can provide TJI joists and AdvanTech subflooring, which are standard on the Homestyle(tm) Series and an option on any other Timberpeg design.


Timberpeg partners with several name-brand manufacturers including Andersen®, Marvin® and Pella® that offer the highest quality windows and doors available. With many styles and options available, their attention to high quality manufacturing standards and outstanding field service assures you of the highest performing, maintenance free windows and doors for your new home at competitive prices.


Timberpeg offers several combinations of wall and roof enclosure systems to effectively deliver various interior and exterior design elements along with superior energy efficiency. A standard Timberpeg Package uses structural insulated panels for the wall enclosures and either the Timberpeg Wrap & Strap system or SIPs on the roof (the roof option will depend on your particular location and building requirements). 

Timberpeg works with two panel companies, Foard Panel and Premier SIPs, to provide high quality 6-1/2" EPS SIPs for the wall enclosure. SIPs are insulated enclosure panels made with two layers of Oriented Strand Board (OSB) with an insulating core made of Expanded Polystyrene (EPS). (Foard panels are also available using an insulated core made of extruded polystyrene (XPS) or urethane (URE) foam). This system is the standard enclosure for the walls only but is also available as an option for the roof enclosure. The benefits to using this technology are many.

Some of the more notable benefits of SIPs are:

  • Allows faster assembly with fewer man-hours than other methods of enclosure
  • High R-values are easily obtained (up to R-50)
  • Fewer interruptions in the wall and roof mean fewer opportunities for air infiltration
  • Provides additional strength to timber frames being built in seismic or hurricane prone areas of the country
  • Using SIPs will gain points towards LEED Certification and Energy Star Certification.
  • Both Foard Panel and Premier Building Systems offer additional services such as pre-cutting for window and door openings and pre-cut chase for electrical runs, which also eliminates most job-site waste. SIPs manufacturers offer experienced installation services in many areas of the country.

The Timberpeg Wrap & Strap Roof System

Depending on your needs and building requirements, you may choose to use the Timberpeg Wrap & Strap roof system in your timber frame package. For more than 30 years Timberpeg has used an individually laid-up enclosure system, which features tongue-and-groove on the interior but gypsum wallboard and plywood backer is an option for those desiring a painted wallboard appearance behind the timber frame. The 1"x 12" wide dead air space between the 1x4 strapping provides a chase for electrical wiring. An important feature of this system is the built-in air space under the roof shingles or plywood substrate when using fiberglass shingles or metal roofing. The airspace provides a "cold roof" - and far superior performance for your home in hot and cold climates. Talk to your representative about which roof enclosure option is best for you.


All fasteners to assemble the Timberpeg timber frame package are supplied. Depending on the choices you make  you will receive the following fasteners:

  • Engineered screws of the appropriate length to assemble the wall and roof components supplied with the Timberpeg Package.
  • Assorted galvanized nails for roofing and Package assembly
  • Stainless steel nails for siding and trim
  • 2" x 24" Kant-Sag metal straps and nails for post-to-deck tie-downs and other critical locations for reinforcement
  • Pre-installed hidden bolted timber connectors, if required by code
  • Panel spline's and spray foam for panel assembly


Timberpeg welcomes your individual creativity for your timber frame home by providing engravings, drop pendants, gunstock posts, and more at your request.

Family names, year-of-construction, or a favorite phrase can be hand-carved into your frame to make your new Timberpeg home a true "heritage home" for you and your family's enjoyment.
