One of the most important features in any log home is how the log walls are sealed between each course of logs to prevent any air or water infiltration.


Strongwood has developed a proprietary 4-Way Seal to seal the log walls.

1. First, each log is milled with a single tongue and groove.
2. Upon installation, an asphalt-impregnated foam insulation strip  is placed on top of the tongue
3. Then we apply a bead of specialty caulking to each side of  the tongue for the entire length of the log.
4. Repeat on every log.


This 4-Way Seal not only provides fail-safe protection against the elements, it is also fully contained between the log courses and therefore not exposed to weather and potential failure/maintenance over time.
