A sealable electrical junction box of one piece unitary construction which incorporates one or more sealing chambers through which one or more electrical wires can pass before they reach the main chamber of the inside of the box. These chambers may then be filled with an expandable foam sealant to form an airtight seal around wires. A flange around the outside of the box allows a vapor barrier to be sealed to the box, so that an airtight seal may be formed around the outside of the box. When properly installed, no air or water vapor can pass from the inside of a building to the outside around or through the sealable electrical junction box.

[ What is claimed is:] [1.]1. A sealable electrical junction box for receiving a sealant to provide a vapor barrier proximate an electrical junction between a plurality of electrical wires, the junction box having an interior and an exterior, the sealable electrical junction box comprising:an enclosure having first and second walls and first and second chambers, the first and second chambers each communicating with the exterior, the first chamber being at least partially defined by a first wall separating the first chamber from the exterior, and by a second wall separating the first chamber from the second chamber, the first wall having a first knockout for anticipated destruction to permit passage of at least one of the plurality of electrical wires from the exterior into the first chamber through a first knockout access opening created by the destruction of the first knockout and defined by the remaining portions of first wall proximate the first access opening following the destruction of the first knockout, the second wall having a second knockout for anticipated destruction to permit passage of at least one of the plurality of electrical wires from the first chamber into the second chamber through a second knockout access opening created by the destruction of the second knockout and defined by the remaining portions of the second wall proximate the second knockout access opening following the destruction of the second knockout;wherein following the destruction of the first and second knockouts and passage of at least one of the plurality of electrical wires from the exterior to the second chamber via the first chamber and the first and second knockout access openings, a vapor tight seal between the exterior and the second chamber can be formed by injecting the sealant into the first chamber such that the sealant engages portions of the first wall proximate the first access opening such that the passage of air through the first access opening is blocked.
