At more than 9 feet tall, the lift and slide door panels on the right side of the corner unit span 12 feet. The panels on the left side stretch more than 21 feet and pocket into the wall, practically disappearing to provide wide, open access to the outdoors.
When the new TerraSpan 90-degree corner door unit is closed, LoE3-366 glass keeps the interior comfortable. The glass is formulated to reject unwanted solar heat, allow natural daylight and maintain outside views. LoE3-366 also blocks 95% of UV light to protect furniture, carpets, curtains and wall coverings from fading.
Blending with interior décor, the TerraSpan unit features an alder wood species with a rich Coffee Bean stain, square glazing bead, and rustic umber hardware. As part of the Ultra Series product line, TerraSpan doors' exteriors are clad in low-maintenance, extruded aluminum that contains recycled content. The outer, metal surface is finished in a custom Copper paint color for a door that makes a statement.
Inviting all areas of the country to use Kolbe products, some TerraSpan door configurations are available with impact certification to withstand hurricane force winds and flying debris. TerraSpan's large panels can pocket into a wall or stack together, and can be arranged in more than 900 operational configurations. These units also feature architecturally-correct coped corners where stiles meet rails. Other options include universal design ADA-compliant bottom panel rails and a choice of screens, hardware, finishes, exterior colors and interior wood species.
Design teams can easily communicate and visually customize TerraSpan doors' dimensions and functionality using Kolbe's 3-D Revit® building information models (BIM). In addition to BIM tools, the website offers 2-D drawings; air, water, structural and thermal reports; warranties, installation and maintenance information, and online videos to demonstrate product operation and performance testing.
