How Does True North Join A Log End For End?

At True North Log Homes we pride ourselves on our ability to manufacture a log home that requires no caulking or chinking—ever!

What size logs do you inventory and how long a wall can you manufacture?

This is a common question and there is a misconception that we can only manufacture a log wall as long as a log itself. The simple answer is here at True North we inventory logs 16′ and longer vs most manufacturers are 16′ and shorter. In fact, True North has up to 40′ logs in inventory for special applications such as window walls or large garage door headers. So, does this mean we can only manufacture a 40′ wall? No, we have completed projects with straight walls over 127′ long. Typically there is a corner or post in most residential homes but we do commercial projects as well. This is completed by joining two logs end to end or commonly referred to as a butt joint in the log home industry. Most log home manufacturers use plywood or wood splines, lag bolts, screws, spiral spikes, and sealants to connect the ends of two logs together. The problem with those connections is that they are susceptible to air infiltration, log wall separation, & structural stability concerns. So how does True North achieve an airtight connection and structural stability?

The ButtSpline® System

True North uses the naturally occurring shrinkage of the log to our advantage, with our patented ButtSpline® technology to make your log home airtight. The log squeezes on the radius of the ButtSpline® at the same time the log shrinks lengthwise, pulling on the ButtSpline® causing the joint to tighten over time. What truly makes this log wall joinery system unique to the log home industry is that we offer a “Zero” Air Infiltration Warranty.

Here’s how it works:
