JBLTH’s Square Log System uses a square log-on-log concept with two types of dovetail corners.
This system uses square log elements manufactured from 6″x12″ or 8″x12″ or 9″x12″ or 10″x12″ stock. Each square log element will have either hewn or planed exterior and interior appearance and will have incorporated into its configuration the JBLTH double tongue and groove system. The exterior surface of the Square Log System does not require chinking. However, the standard square log element has an indention on the exterior and/or interior surface at each layer joint that is suitable for simulated chinking. A V-groove is available as an optional exterior and/or interior groove.
