Milled logs are the most common logs used in log home construction.  These logs are formed by feeding logs through a computerized precision cutting lathe that cuts the logs into various shapes, such as the popular D style, and cuts the tongues and grooves which make up the sealing system  Tennessee Log Homes are cut to an accuracy of 1/32 of an inch.  This accuracy along with our sealing gasket  insures that the outside air stays out and the inside air stays in.
