Currently under development, our prototype bubble glass logs and siding provide many advantages beyond what conventional concrete can deliver in these products. They use a tongue and groove interlocking method and can be made in a variety of lengths.
They are fire resistant, insect resistant, and provide for a much higher R value than conventional concrete and  can be stained to resemble many types of wood. Utility runs can be molded into them for ease of utility installation.
Using bubbleglass as the aggregate in the logs provides for up to 50% lighter weight than conventional concrete and provides up to 6 times the R value.
This results in superior acoustical properties, insulating from noise as well as heat and cold. Logs made with bubbleglass based concrete accept nails and screws without having to use special tools or fasteners.
