Log homes blend sustainably grown timber and hi-tech solutions

While log homes from Bracebridge, Ontario-based True North may look rustic on the outside, hi-tech secrets make these homes truly high performance.

 Built from white pine heartwood timber sustainably grown in northern Ontario and Quebec and certified by the Forest Stewardship Council, True North homes feature a log-lock compression system that overcomes one of the common problems of log homes.

Because wood logs may shrink and settle over the years, there may be gaps that lead to air infiltration. However True North developed a system that actually ratchets itself tighter as the logs shrink.

This provides the homeowners significant eco and cost benefits, and allows the only 25-year "zero" air infiltration warranty in the industry, according to Rob Wrightman, president of True North. The system also eliminates the need to caulk or chink the cracks in the wall, reducing use of chemicals and reducing maintenance costs.

Log Locks are installed in the center of the log at approximately six-foot intervals and two feet back from the corners. The average size log home will require approximately 40 Log Locks depending on log home design, to ensure the log walls remain tight. Competitor's thru-bolts installation time requires 2 days whereas True North Log Home's Log Lock cuts installation time to 2 hours.

For additional building envelope tightness, the company developed the patented Keylock Air Seal Corner, which increases a home's efficiency exponentially. The system locks and seals the logs from movement and airflow.

Other green building features include:

  • Modular components that allow for flexibility in design, as well as reducing the carbon footprint
  • Fast exterior construction, usually only a few days to roughed in status.
  • Joined together without screws or nails
  • Exterior shell is weather-tight
  • Interiors can be retrofitted to increase sustainability with options including energy efficient windows, solar panels, spray foam insulation, soundproofing with sheep’s wool, and radiant floor heat.
