At Heritage Log Homes, our double tongue-and-groove, saddle notch corners virtually eliminate air infiltration at corner joints, allowing your home to maintain maximum energy efficiency.

Each log is milled with a pair of parallel ridges (tongues) that run the length of the timber and are covered with strips of foam gasket material. When two logs are stacked, the gasket-covered ridges on top of the lower log fit tightly into precision-milled grooves that are cut into the underside of the upper log.

Heritage Log Homes is unique because we are the only log-home company in the industry that incorporates this patented double tongue-and-groove feature into corner joints, which means your home is tightly sealed from top to bottom and side to side.
