Energy efficiency is a must for any home. Logs are a natural reservoir for heat energy. To enhance this natural thermal mass efficiency, for example, each log in a pre-cut log package is coped using a Swedish cope. The radius of this cope is slightly smaller than the log diameter to maintain a uniform fit along the length of each log as the logs settle.

To increase weather tightness each pre-cut log package includes the following: foam gasket tape, (for the cope between the logs), foam insulation (for dado joints), and sill seal (for bottom plate logs). Each pre-cut timber package includes the following: foam gasket tape (for the dovetail corners), expanding foam insulation (for the dado joints), and sill seal (for the bottom plate logs).

To further increase weather tightness, due to the nature of logs and timbers, you will want to caulk the corners of your home. For a log home you may choose to caulk or chink the exterior and interior of your home. For a timber home you may choose to caulk your home, but you will have to chink the exterior and interior of your home, due to the design of timber homes.
