In the early days, felled logs were transported using simple methods such as rivers to float tree trunks downstream to sawmills or paper mills. This practice, known as log driving or timber rafting, was the cheapest and most common. Some logs, due to high resin content, would sink and were known as deadheads.
Shaped like a “U” or channel to catch water (e.g., where the edge of a tile roof meets a wall). Through wall flashing Spans the thickness of the wall and directs water to weep holes. Cap flashing (drip cap) Often used above windows and doors. Drip edge A metal used at the edges of a roof. Step flashing (soaker, base flashing)
At very low fan speeds, less than 1 m/s, the air flow through the stack is often laminar flow, and the heat transfer between the timber surface and the moving air stream is not particularly effective (Walker et al., 1993). The low effectiveness (externally) of heat transfer is not necessarily a problem if internal moisture movement is the key ...
Built in 1640, C. A. Nothnagle Log House, located in Swedesboro, New Jersey, is likely the oldest log cabin in the United States. A conjectural replica of the log cabin in which U.S. president Abraham Lincoln was born, now at the Abraham Lincoln Birthplace Mortonson–Van Leer Log Cabin in New Sweden Park in Swedesboro, New Jersey A replica log cabin at Valley Forge in Pennsylvania A log house ...
Logs with a higher density than the density of water would sink. [2] Other logs would get caught in jams, sloughs, or floods, and become lodged in the riverbed. Such logs were often known as "sinkers" or "deadheads." Loggers attempted to reduce the number of logs which remained in the river in order to maximize profits, but some losses were ...
In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.

D-shape logs: round on the outside and flat inside; Full-round logs: fully round inside and out; Square logs: flat inside and out, and may be milled with a groove which could be chinked. When dealing with milled logs, chinking is a personal preference and not required to seal a house; however, a log house will eventually leak if it is not ...
