Glossary of Lodge Log and Timber Products Terms


All Thread:   5/8" x 3' section of threaded rod that is attached to a J-bolt embedded in the foundation using a coupler. The 1000# tension spring sits at the top of the log wall on the all thread keeping constant pressure on all the logs in the walls thereby eliminating the common problems associated with log homes. It is a vital part in a log home's design, which is efficiently dealt by the usage of the Thru-Bolt system that was pioneered by Lodge Logs in 1975.

Board & Batten Siding:   1" x 12" boards installed vertically and seams covered with 1"x4" battens. Can be done with 1"x10" boards and 1"x3" battens.

Checking:   Large cracks in the log or timber caused when drying. These are greatly reduced in Lodge Log and Timber Products homes by our specialized drying process and the stress relieving, drying kerf innovated by Lodge Logs.

Clapboard Siding:   Horizontally installed boards that overlap at the top of the lower board. There is no milling so the siding will not have a flat profile when complete.

Cold Roof:   A type of roof system that allows air flow between the inner and out layer of roofing. This is the most common style of roofing used in log home construction. The insulation is between the roof members and is typically hidden from sight. If this method is desired and employed in a log home design and construction then decorative components can be utilized to partially hide the appearance of exposed beams and rafters.

Composite Decking:   This is a decking material made from a mixture of plastics and fibers since this material lasts much longer than wood decking, which has chances of getting oxidized to an undesired state within a few years of exposure. Follow the manufactures cleaning and maintenance recommendations to slow or prevent this.

Coupler:   5/8" x 2" threaded nut allowing 3' sections of all thread to be attached to each other. Part of the thru-bolt system innovated and implemented by Lodge Logs since 1975.

Crawl-space:   Area below the framed floor system of a log home's floor. Usually about 3 to 4 feet high, from the bottom of the foundation footing to the bottom of the main floor.

Decking:   Dimensional lumber or composite material installed over the floor joists to complete the structural floor system.

Dimensional - Nominal Lumber:   Typical framing lumber milled for 2"x4"(1-1/2"x3-1/2"), 2"x6"(1-1/2"x3-1/2"), 2"x8" (1-1/2"x7-1/4"), 2"x10" (1-1/2"x9-1/4"), 2"x12" (1-1/2"x11-1/4") this lumber is surfaced on 4 sides and is actually smaller than the actual call sizes.

Dimensional - Rough-Sawn Lumber:   Non typical framing lumber milled to actual size. This lumber is used for trim and construction that will not be covered.

D-Log:   Style of log offered by Lodge Log and Timber Products that is Slabbed on the interior side to create a flat wall. The Slabbing is stopped just before the corner to ensure a tight and sound saddle notched corner construction.

Draw Knife:   Specialty tool of log smiths used to peel the bark from a log.

Dry Standing:   Trees that have died in the forest due to forest fire or insect infestation. These trees will have varying moisture content from tip to base causing shrinkage to vary from one end of the wall log to the other with the possibility to compromise the structure. Lodge Log and Timber Products does not use dry standing logs in any of its log home constructions.

Footing:   Structural concrete at the base of the foundation system that supports the weight of the log house and other applicable loads that are part of the custom log home design.

Hand-Crafted:   Term used to describe the type of log construction where milled logs are not used. Logs will be notched and coped by hand and sometimes at a factory where they assemble the log house and then disassemble the house for shipping. This is the most expensive type of log home design.

Hand-Hewn:   Process used by Lodge Log and Timber Products to give milled logs an appearance of rustic living.

I-Joist:   Engineered lumber that resembles an "I" from a cross section, used for structural floor joists and rafters.

J-Bolt:   5/8"x12" J shaped bolt that is embedded in the concrete foundation for attaching the thru-bolt system. This secures every wall log to the foundation.

Kiln Dried:   Refers to lumber dried artificially in warm chambers. The heat is regulated to prevent sudden loss of moisture, thus preventing checking, warping, and other defects that afflicts log houses. The Industry standard is 19% 1" from the surface. This allows the core of the log to be very high in moisture content allowing shrinkage, settling, warping and checking, which can still cause a major concern. At Lodge Log and Timber Products the walls are dried to 15% of the moisture content at the heart with the aid of a relief kerf thus greatly reducing checking and almost eliminating shrinkage of wall logs used in the log home.

Knee Brace:   Diagonal member used to support a horizontal purlin or girder that does not span across two points. Usually purlins are installed under roof to support a large overhang.

Log Girder:   Horizontal member spanning anywhere between two or more points that supports a bearing load, such as the floor joists.

Log Headers:   Horizontal member spanning anywhere between two or more points that transfers the load above to the sides of the desired opening.

Log Mantels:   Log shelf above a fireplace.

Log Purlin:   A horizontal member attached perpendicular to the truss top chord or rake wall for supporting the roof rafters or panels.

Log Rafter:   Framing member used as part of a system for the structural part of the roof framing. Typically log rafters will be spaced around 32 inches apart and will span from the ridge beam to the top wall plate.

Log Ridge Beams:   Ridge Beams are the large structural members that support the roof rafters at the peak of the roof.

Log Siding 2x:   Typical log siding milled from boards to moderately resemble a log structure on the outside of the house.

Log Valley:   Structural member used to support the roof rafters at the intersection of two sloped roofs.

Peeled:   Term used to describe the finish look and texture of a log where it resembles a hand peeled log. Lodge Log and Timber Products offers this effect on post and poles for a natural effect. These will be varyingly tapered from tip to base depending on the length desired or applicable.

Pier:   Individual member installed vertically, extending above grade from the foundation footing just below frost-line and is built upon. Usually used for decks, but can be used for primary foundation system in many places.

Pith:   Reddish layer under the bark that is not removed completely while peeling the log.

Relief Kerf:   Specialized process used by Lodge Logs to relieve stress on the drying log in a controlled location (top of log) that does not affect the integrity of the log, but greatly reduces checking.

Re-sawn Cedar:   Cedar lumber that is re-sawn on the exposed side to create a rough surface, reducing cupping caused by direct sunlight. Typically used as fascia and trim, resembling rough-sawn lumber.

Roof Eave:   Overhang of a roof that is not sloped.

Roof Rake:   Overhang of a roof that is sloped.

Rustic Corrugated Metal:   Corrugated metal panels that have no rust protection or galvanization. It can be pre-rusted or left to rust naturally, and will eventually resemble the aged tin that was used on many mountain style homes decades ago, without causing leaks. This material is used for roofing and siding applications.

Rustic Pine Board:   Rough sawn pine planed smooth, but not deep enough to completely remove the character saw marks from the mill. Usually 1" x 4", 5", 6" or more.

Rustic Pine Trim:   Rustic Pine Board used as trim for windows, doors, etc...

Settling Jack:   Aid in the compensation of settling log walls. It has a threaded rod mounted to a steel plate with a nut acting as the height adjuster, with another steel plate on top of the nut. The bottom plate is screwed to the floor and the top plate is screwed to the bottom of the vertical log post. The threaded rod will pass through a hole in the center of the upper plate and into a predrilled recess in the log. Note: It takes years for the logs to completely settle, which means that it will take some time for the jack to be lowered to a point where it will not be seen by someone in the room. (However due to our specialized drying process and thru-bolt system these are not needed in Lodge Log  and Timber Products Homes)

Shiplap Siding:   Horizontally installed boards that overlap at the top of the lower board. This siding is milled to create a flat profile when complete.

Siding:   Exterior veneer installed to the exterior walls as a finish material.

Slabbing (Slabbed):   This is the process of cutting a portion of a round log to create a flat surface. The amount cut depends on the log home plan and the application in which the log will be used.

Stem-Wall:   Foundation wall (usually concrete) that is constructed on the footing, extending above grade upon which the log house will be built. Lodge Log and Timber Products provides custom layout for each house, these details show exact placement of the J-Bolt in the foundation. The house logs are pre-drilled to these specifications for assembly using the Thru-Bolt system.

Swedish-Cope:   The concave shape on the bottom of the milled log, allowing the tightest fit from one log to another. Lodge Log and Timber Products applies a single tongue and groove to its Swedish-Cope, producing an efficient seal between the logs.

Thru-Bolt System:   Innovated by Lodge Log and Timber Products in 1975, this system was designed to eliminate potential pitfalls caused by shrinkage, settling, warping and twisting of logs, ensuring a tight fit between logs and thereby adding structural strength to the walls.

Tension Spring:   Steel coil, 1000# spring attached to all the threads at the top of the log walls, thus compensating for any shrinkage or swelling. Doing this secures the log home and also eliminates the need to chink the log walls. Lodge Log and Timber Products Homes is the only manufacture to secure logs to the foundation and not the sub-floor.

True Half Log Siding:   Half of a log used as siding. This is usually installed over conventional framing to imitate a log house on the outside.

Warm roof:   A built up roof without ventilation that is insulated on the top rather than between the rafters or below them. This method is most common in homes using exposed rafters and beams.

Warranty:   A written guarantee given to the purchaser by the manufacturer or dealer, specifying that the manufacturer will repair or replace defective parts for a certain period of time. Lodge Log and Timber Products warrants it's product against defects with a limited lifetime warranty.
