Definition
A door build where insulation is bonded between two steel skins — steel, foam, steel, like a sandwich. Compared to a single-layer door or one with loose foam backing, a sandwich door is quieter, stiffer, more dent-resistant, and far better at holding garage temperature through Four-State winters and summers. It is the construction Door Serv Pro recommends for attached garages, since the garage wall is effectively part of your home's thermal envelope.
