The shield is made of 16 ounce copper sheet metal.
Several photographs depict various details of how the shield was fabricated and installed.
Termite shields are physical barriers made of sheet metal which are fitted to the foundation of a house to exclude subterranean termites from tunneling up into the wood framing. Termite shields are often used in tropical countries where the risk of termites is more familiar to home owners and architects. In North America over the last 50 years, soil termiticides have become the dominant method of termite control and shields are rarely used. However, with increasing concern about the excessive use of pesticides, many people are looking for non-chemical alternatives to soil termiticides which can be installed as preventive barriers during construction. Recently, a situation arose where soil termiticides could not be used due to the high water table on the building site.
