Termite shields can be made up of various materials. One type of termite shield is made from various sheet metals including
Lately, granite and Polyvinyl chloride (PVC) shield can be installed into tiny brick open spaces where termites can enter the building surrounding the whole perimeter of the property. The termite shield is too thick for the termites to chew and penetrate the material forcing the termites to migrate into the open where they can be more easily eradicated. The benefits of using this type of material is that they are sustainable to the environment being awarded Environmental Choice Declaration from the Environmental Labelling Association.[3] Other benefits include being cheaper than metals, and can be coupled with other shield protection systems.
Problems
One problem with termite shields is the gaps which exist at seams and at openings where steel reinforcing bars penetrate the metal shield. Since many species of subterranean termites can enter through openings >1/20 Inch (1.27 mm), these gaps must be sealed with a sealant known to block termites. Additionally, termite barrier sealant should be used underneath the shield, so termites are forced to go to the exterior of the structures.
Other materials
There are two other materials called "termite barriers" rather than "termite shields" which have been evaluated by the International Code Council.
