Create an expansive scenic addition to your design project with Kolbe’s Ultra TerraSpan® lift and slide door. TerraSpan doors open up rooms dramatically by extending the living space to the outdoors, and are ideal for many applications, from new residential projects to commercial buildings. Attention to visual details also gives the TerraSpan the same aesthetics as our other Ultra Series products for a seamless match throughout an entire project.

Panels can either recess into a wall pocket or stack in various configurations within the opening. TerraSpan doors are also available as 90° corner units. Each door panel is only 2-1/4" thick, allowing for a less space consuming unit, yet is designed to provide both versatility and durability. The exterior is covered by a thick extruded aluminum cladding, while the interior has the warmth and beauty of natural wood.

A wide selection of choices are available to specify a TerraSpan to meet your needs. Many glass options, finish options and over 900 operational configurations make the possibilities nearly limitless. Talk to your local Kolbe dealer to learn more about all that Ultra TerraSpan lift and slide doors have to offer.
