While these ethnic groups had a long-standing cultural background in log construction in Europe, and were comfortable in its continuation here in pioneer America, it seems that only the English had no experience building with logs and instead clung to their own familiar building practice of timber framed houses sided with sawn clapboards. We have several log cabin floor plans and designs to choose from. Virtually all logs/timbers, regardless of how straight they may appear, have some varying degrees of left or right-hand spiral grain. Other strategies employed include compound dovetail notches on the plates, the load bearing and structurally superior stepped-lapped rafter seat, and the vertical pinning of the knee-wall logs at 4 feet intervals with 1¼” hardwood dowels. Log Cabins built with you in mind. This site uses Akismet to reduce spam. Where in the past it was quite common in log and timber frame structures to find a square peg securing the rafters to the top plate (and you may still use this traditional method of attachment if building code allows), I find it less of a compliance issue to use a fastener whose hold-down characteristics can be quantified to building officials. Don’t be tempted to purchase a stain/preservative from the big-box stores. These plate logs and their attachment are a critical structural component, as they must be up to the task of countering the roof thrust that is inherent in rafter framing, which is generated by roof loads that push down and out on the eave plates and (in story-and-a-half structures) the knee-wall logs below. Here are a few floor plans that we have come up with. Because of this, we can add a insulation break with a Wood fiber board and a interior stick framed wall for insulation purposes which gives us above building code standard R-values (R-26 with 2″x4″ interior wall and R-34 with 2″x6″). It is 18 x 26 with a classic front proch. Log structures need a superior product that has been specifically developed and tested for its unique requirements, and one of the most important decisions you will make once construction is completed is the quality of the finish/stain you will apply to the exterior of the logs. This tie beam is supported at mid-span by a braced and pegged 8"x 8" post. Partnered along with material handling issues and my local mills saw-length capacity, these factors will dictate the size of the log cabins. You are building a house that has all the creature comforts such as: plumbing, electrical, septic or sewer, and maybe even heat/air? Contact woodmizer sawmills to get a list of owners near you. Gasket groove on inside of notch, 3/4" wide x 3/8" deep. It has been shown that the borate solution in timbers will tend to leach out of the wood once it has been exposed to rain, unless a high-quality stain/sealer is applied to logs soon after installation, usually within a few days. Email Address * GRK rafter screws secure rafters to top plate, providing hold-down capacity while supplementing the stepped-lapped rafter/plate timber joinery. Dovetail. You will need to prepare your building site, foundation, and subfloor prior to the log kit assembly. Chink materials you will need:1) GripStrip foam backer.2) Chink joint insulation (sheepwool, mineral wool, or fiberglass)3) Topical chinking. The square foot of living space will cost an average of about $60 – $95 and includes all the outside and inside walls and insulation, timber, trusses and roofing, windows and doors, 2nd floor and stairs, porch, decking and railings. The walls of a TrappeurHome, unlike conventional log homes, have minimal settling or shrinkage after construction, meaning once you’re finished there are no ongoing maintenance costs. These collar ties feature half-lapped, dovetailed joinery and are fastened to their rafter mates with white oak pegs. You can alter this design (move the porch to the gable end), or start from scratch and we can arrive at a design that is unique to your lifestyle. ILBA Log Building Standards state that green logs (in chinked dovetail) must be allowed to settle approx. A concrete driveway on a sunny, hot summer day is an example of thermal mass because it absorbs, holds, and re-radiates heat well. Our dovetail log wall system cost is maybe 10% more and at least twice as energy efficient than a conventional 2×6 stick framed wall system. The loft is framed using massive posts and beams with pegged, wood-to-wood joinery and with an 8”x12” tie beam spanning the 18' width and joined to the eave wall logs with a housed dovetail joint. Notch extensions are additional amounts of wood left on the log ends and aid in the protection of the dovetail notches from end grain deterioration. Unlike timberframe construction where the layers of exterior skin protect against the elements, a log wall acts as both the structural frame and the first/last line of defense against air and water intrusion. Our innovative wall system allows you to choose any interior wall finish from log wall paneling to drywall and beyond. I work with a log building system which allows a wall thickness of 8" and incorporates 8" x 12" wall logs of two different profiles: 1) rectangular-sawn timbers that result in an even, symmetrical horizontal chink-gap between log courses, and, 2) for those interested in a more authentic/traditional look, a log profile where the log is hand-hewn and flattened on 2 faces with the broadaxe, and the chink joint follows the natural contour of each log. This is the structural framing method employed in 18' x 24' cabin. Dry logs do not deteriorate. Energy efficient, healthy and sustainable dovetail log homes. competitor and why should someone buy our package? Not too bad in itself, but compare this to the standard 6” stick framed wall packed with fiberglass which carries an R-19 rating, and the log wall lags a bit behind when using that standard of measure. They are highly effective as a wood preservative in preventing fungal decay and are deadly to most wood-boring insects (termites, old house borers, carpenter ants, etc. Trappeur Homes log walls are built with the venerable dovetail corner joint. In the end though, engineering specs will have the final say in determining the appropriate roof framing system for your particular situation.

Another benefit with our wall system is that you can run you electrical and mechanical in the 2″x4″ or 2″x6″ liner wall used for insulation and finish the interior wall to look like the logs, drywall or combine wood and drywall. Our log cabin kits include all structural logs, handcrafted in our assembly yard, then delivered and set up on your building site. The sawmill where I obtain the timbers that will be incorporated into your log structure is given a set of standards regarding the quality/grade of logs and acceptable sawing methods needed to produce structurally sound timbers for a log structure. * All timbers clearly numbered/labeled according to their orientation within the structure. 14 degree dovetail slope. Each dovetailed corner notch, and all wooden joinery is laid out (framing square, chalk-line, level & protractor) and handcrafted (mallet, chisel, slick, hand saws, axes) with the traditional hand-tools of the past.
