Patio Doors

Sliding glass patio door in white with prairie grids. Sliding patio doors open horizontally, along the plane of the home. The maximum glass surface construction of sliding patio doors allows them to let in a lot of natural light. Because sliding doors don’t swing open, they perfect for use in applications where the wall space required by a hinged “swing in door” is not available or, where a projection may present a safety issue.

Our patio doors can be made with either two or three panels. Two (double) panel doors can be manufactured to cover 5’, 6’, or 8’ door widths, while three (triple) panel doors are used for 9’ and 12’. Jantek’s Patio door comes standard with our triple pane tempered Low-E safety glass which provides an industry leading R5 insulation value to save you energy and capture comfort.
