Thermabuilt^®
R-5 Insulated Doors

All of our doors comply with the 2006 and 2018 International Energy Code standards, and are Energy Star Compliant. Featuring 4-side weatherstrip jambs, our doors can be bored at any height, and are branded with ThermaBuilt®  on the edge, making it easy for building inspectors to verify compliance.

Built from hardboard or birch, choose from flush-cut, angled top, raised panel or double bi-hinge configurations.

Choose any hinge from our stock selection, and add options such as aluminum sills, ball catches, wood knobs, and counter sunk Neodymium rare earth magnetic catches.
