Type of Wood

All material is a northern spruce grown in a cold climate, creating a tight grain and is the most accepted and stable material for log construction. The wall logs sizes and moisture content is consistent, allowing for accurate production and assembly. The wood has been kiln dried to 16% moisture content and can air dry to less than 14% prior to milling.

Mounting first two rows of wall logs to foundation

Concrete - Mounting first two rows of wall logs to foundation. The first two rows of wall logs must be secured to the foundation using long screws or lag bolts. Local wind codes may require the use of additional metal bracket on the interior. These brackets would be lagged or bolted to the floor and fastened to the wall log. When insulating the wall these brackets are not seen. A moisture barrier can be applied between the first wall log and the surface it's being mounted to. Do it yourself building kits.

Wood sub floor - Mounting first two rows of wall logs to foundation. Wood sub floors are built prior to arrival of the package using local materials. Floor plans are provided in advance to determine the location of blocking required under interior walls. Do it ypourself building kits. EZ Log Structures.

Stacking of wall logs

Stacking of wall logs. Logs are stacked without the use of sealants between the logs. The logs must be allowed to expand and contract to climatise with the local enviroment. A wall height of eight feet high will shrink up a little over first year as the moisture content of the lumber neutralizes. During production wall logs are pre-drilled in the horns to accept stainless steel rods that run the entire height of the wall. Upon completion of wall assembly, the provided rods are dropped into the holes from the top and secured using metal washers and nuts. In addition rods are placed at each interlocking junction of wall logs. The horns hang over the foundation, which allow access to tighten the nuts as the wall logs shrink.

Stacking of wall logs. Rods can also be applied at either side of windows and doors, or any position in the walls to accommodaste regional sheering requirements in hurricane or earthquake zones. When rods are positioned at locations other than horns an access port for tightening is cut into the logs of three inches wide three inches high at the wall base. Wood plinth blocks are used on the outside and inside to cover the access ports. Do it yourself building kits. EZ Log Structures.

Length of wall logs

Length of wall logs. When longer walls are required, a dove tail joint is used to connect logs. This joint is pinned on both sides using a wood dowel, driven into pre-drill holes. In long walls wood dowels are used to strengthen the wall. Do it yourself building kits. EZ Log Structures.

Gable Ends

Gable Ends. Visible gable ends. Do it yourself building kits. EZ Log Structures.
Gable Ends. Where wall logs are not screwed together, tapered logs used in the gable end walls and interior divisional walls are stacked in sequence and individually screwed together. Purlins stacked two or three layesr high. They are placed in position during the stacking of wall logs and are locked in position by overlaying wall logs. The purlins are screwed to the wall using long screws or lag bolts. Purlins run the lenth of the building and locked in at all gable positions. When purlins are double or triple high, they are screwed together during assembly. Do it yourself building kits. EZ Log Structures.
Gable Ends. In higher wind or earthquake regions, 3/8 inches stainless steel rods can inserted trough the purlins and the entire height of the wall. This ties the purlins to the building. Do it yourself building kits EZ Log Structures.

Roof Purlins & Snow Loads

Roof Purlins & Snow Loads. To meet local snow load requirements the number of purlins can be increased and the height of purlins can be increased by stacking two or three high. Purlins for homes and cabins are spaced twenty four on center or less at time of production. In most regions, double high purlins will meet snow loads. Local engineering will determine the required size an quantity prior to production. Do it yourself building kits. EZ Log Structures.

Windows & Doors

Windows & Doors. Windows and doors are not fastened to the wall logs with fastenners. This allows free movement for the logs to settle as they climatise. The wall logs have a dado (groove) cut into the edge at the rough opening and the window jamb has a protruding strip of wood build into the jamb that fits into the dado. This joint prevents with window from coming out of the wall, creates an air barrier and allows the wall logs to settle. Do it yourself building kits. EZ Log Structures.
Windows & Doors view. Two inches of space must be allowed on rough opening at the top of all windows and doors. This cavity is reduced over time as the wall logs settle. Larger trim boards are used on the outside and inside. Do it yourself building kit. EZ Log Structures.

Using Local Windows

Using Local Windows. When local building codes require specific windows and doors, local windows are used. Rough openings are cut during production to fit the local windows and door sizes. A spacer block must be fastened to the outside of the window frames at time of installation. This spacer block is equal to the depth of the studs being used and is seled and fastened to the bottom and sides of window jambs and sides only of door jambs. Do it yourself building kits. EZ Log Structures.
Windows & Doors insulation. When the exterior trims (brick mold) is applied on the outside and it creates a cavity for the wall logs to move freely between the spacer block and the exterior trim board. The exterior trims are not fastened to the wall logs. Wall logs floats freely between outside trims and the spacer block fastened to window or door jamb. Interior trim boards are not fastened to interior wall cover boards, allowing the window to lower as wall sttles. Do it yourself building kits.

Flashing

Insulating Walls. Where flashing is required above windows and doors a saw kerf is cut in the wall log two inches above the exterior top trim board. Flashing is inserted to the saw kerf and sealed. (do not fasten to wall). As the wall logs settle the flashing will move down freely over the top exterior trim boards. Do it yourself building kits. EZ Log Structures.

Insulating Walls

Insulating Walls. Studs with a depth required for the insulation being used, are installed sixteen or twenty four inchec on center. Metal brackets are provided to attach the studs to the wall logs. No top plate or bottom plate is required. The metal brackets are designed to allow the exterior while the studs remain stationary. Do it yourself building kits. EZ Log Structures.
Insulating Walls. Studs are cut two inches short of ceiling height to accommodate shrinkage. A crown molding attached to the ceiling lower as the wall logs settle. Do it yourself building kits. EZ Log Structures.

Insulating Ceilings - Option 1

Insulating Ceilings - Option 1. Insulating the ceiling can be done from the interior by placing insulation between the purlins and then applying cover board to the underside of the purlins. Insulating from the underside reduces ceiling heights. Walls can be increased in height if requested. Do it yourself building kits. EZ Log Structures.

Insulating Ceilings - Option 2

Insulating Ceilings - Option 2. Insulating from the outside requires a buildup using local materials. Insulation is installed and then a layer of plywood before instaling the finished roofing materials. Larger fascia trims are required for this method. Interiorwall cover boards must be cut two inches short of the ceiling and crown molding is fastened to the ceiling. As the wall settles the crown molding lowers. Do it yourself building kits.

Vapor Barrier & House Wraps

Must be determined by local engineers based on regions climate.

Wood Treatments

The wood must be sealed on the interior and exterior wall surfaces immediately following assembly. High quality treatments are available locally; similar to what is used on wood decks or fences. Research the wood treatments used in your region from approved manufacturers.

Maintenance

During the first year, storm rods need to be tightened as the moisture content reduces and the building settles. At the end of the first year tightening will not be required. Exterior and interior staining or painting will be required as recommended by the stain or paint manufacturers.
