Insulpour thermal entrances use IsoPour thermal-break technology to provide high thermal performance, strength, and interior and exterior dual-finish options. The technology merges pour and debridge thermal break with polymer isolator technologies. The door and frame use IsoPour to create assemblies with higher structural performance, enhanced energy efficiency, and greater design flexibility. With sightlines that match non-thermal doors, the entrance is available in 250T narrow, 350T medium, and 500T wide stile options. Multiple cross-rail sizes and bottom rail heights are available.
