Traditional windows have hollow chambers in their frames that allow air to circulate, creating thermal bridging and energy loss. FoamCoreX™ technology fills every chamber with high-density polyurethane foam, creating a continuous thermal barrier that revolutionizes window performance.
Custom Contracting is the only certified FoamCoreX™ installer in Ontario, ensuring you get authentic technology with factory-trained installation and full warranty protection.
