TerraSpan Doors offer Impact Resistance
Kolbe's Lift & Slide Doors up to 10' Tall have Achieved Impact Certification
Wausau, Wis. (Oct. 2011) – Kolbe's Ultra Series TerraSpan® Lift and Slide doors' 10-foot-tall units have been certified to meet the impact testing criteria for large missile impact Level D, design pressure (DP) 45 rating, and Wind Zone 4 testing standards (IPD4). The IPD4 rating indicates these products are an excellent choice for hurricane areas, as well for any region of the country that is subject to severe storms or gale-force winds.
Successfully completing the extensive testing to meet or exceed the strict building codes of the coastal region, TerraSpan’s doors join Kolbe's K-Force® impact products. "These products are specially designed with the strength to withstand hurricane force winds and flying debris, while presenting the same beautiful appearance for which Kolbe windows and doors are known," says Cindy Bremer, Kolbe's vice president of marketing.
TerraSpan's large panels can pocket into a wall or stack together, and can be arranged in more than 900 operational configurations. A maximum of 10 stacking or pocketing door panels in widths up to 6-feet may be specified for a single, expansive opening. 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.
Along with impact resistance, TerraSpan doors are available with climate-appropriate, high performance glass options that balance daylighting and energy efficiency. These units also feature architecturally-correct coped corners where stiles meet rails, universal design ADA-compliant bottom panel rails, and a choice of screens, hardware, finishes, exterior colors and interior wood species.
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 surfaces are finished in environmentally-friendly, durable coatings and a broad palette of colors. For the interior, a range of sustainably-harvested wood species can be chosen for trim, such as those certified by the Forest Stewardship Council. Kolbe’s doors' environmental attributes also support projects pursuing green goals including ENERGY STAR®, Green Globes™ and the U.S. Green Building Council's LEED® Rating System™.
