Abstract
A construction element for forming an expansion joint, wherein the construction element acts as a physical and chemical barrier against the penetration of insects, in particular termites, into a structure, the construction element comprising a closed cell polymeric foam containing at least one insecticide substantially distributed throughout the polymeric foam; wherein on at least one outer surface of the construction element there is a water resistant adhesive attached thereto and a removable cover releasably attached to the adhesive whereby the removable cover is adapted to be removed upon application of the casting element.
Claims22
A construction element capable of forming an expansion joint, the construction element comprising
- a polymeric foam containing at least one insecticide substantially distributed throughout the polymeric foam;
- wherein the polymeric foam has a cell size of approximately 0.5 to 2 mm;
- and
- wherein on at least one outer surface of the construction element there is a water resistant adhesive attached thereto and a removable cover releasably attached to the adhesive whereby the removable cover is adapted to be removed upon application of the construction element;
- wherein the construction element acts as a physical and chemical barrier to impede the ingress of insects into a structure;
- wherein the polymeric foam has a compression set at 22 hours of less than 6%;
- wherein the polymeric foam is closed cell polymeric foam;
- wherein the polymeric foam is manufactured at a temperature of less than 180° C. and is prepared primarily from a blend of a crosslinked polyethylene and a low melting ethylene-vinyl acetate (EVA) copolymer;
- and
- wherein the polymeric foam has a density of between 23 to 28 kg/m3.
A method of protecting a structure against the ingress of insects into the structure, the method comprising the step of positioning one or more construction element(s) at a position(s) during the construction of the structure to form a barrier to at least impede the entry of insects, the construction element comprising
- a polymeric foam containing at least one insecticide substantially distributed throughout the polymeric foam;
- wherein the polymeric foam has a cell size of approximately 0.5 to 2 mm;
- and
- wherein on at least one outer surface of the construction element there is a water resistant adhesive attached thereto and a removable cover releasably attached to the adhesive whereby the removable cover is adapted to be removed upon application of the construction element;
- wherein the polymeric foam has a compression set at 22 hours of less than 6%;
- wherein the polymeric foam is closed cell polymeric foam;
- wherein the polymeric foam is manufactured at a temperature of less than 180° C. and is prepared primarily from a blend of a crosslinked polyethylene and a low melting ethylene-vinyl acetate (EVA) copolymer;
- and
- wherein the polymeric foam has a density of between 23 to 28 kg/m3.
