NUDURA has revolutionized the ICF industry from its inception, believing that making quality products that feature innovation to make the building process easier and faster is crucial to our customers. We believe that driving innovation and changing the status quo allows us to provide the most innovative line of Insulated Concrete Forms on the market.That innovation continues with a new breed of Insulated Concrete Forms. The One Series by NUDURA, featuring DURA MULTILINK Technology™, is the industry’s only multi-link form offering builders and architects unmatched versatility for projects designed using ICFs. At the core of this innovative line is DURA MULTILINK Technology™, a newly designed web that offers users the ability to create a wide variety of custom multi sided form combinations for a variety of building types from commercial to residential. DURA MULTILINK TechnologyTM features all of the original innovations that NUDURA is known for. DURALOK Technology™, locking forms together with a triple tooth interlock to eliminate the need to tie, glue or purchase additional clip accessories to keeps forms together. DURAMAX Technology™, the industry’s largest standard form on the market, 8 feet (2.4m) long by 18 inches (457mm) high placing 12 sq. ft. (1.11m2) of wall area in one building step.
The One Series will offer users the ability to reduce labor by eliminating the need to strip foam for elevator shafts, stairwells and other areas that require non-combustible products. The One Series gives Architects the ability to have more versatility with design for multi-storey, educational and commercial warehouses. For home builders, the One Series is ideal for pools and anywhere only one side of foam is needed. Transition between concrete and foam is seamless, the unique design allows concrete to meet with the outside edge of a NUDURA foam panel. The DURA MULTILINK Technology™ web, uses smaller attachment points that have been created to alleviate webs being visible in the concrete side of the wall. This innovative design features only two small connection points per web that are easily covered over and hidden. The end result is a smooth interior or exterior surface.
How does it work? The One Series combines traditional forming methods and Insulated Concrete Form technology together. NUDURA supplies all of the materials necessary to complete the mulit-link form, from the webs, form ply, screws and specially designed jig to make assembly easy and fast. The form ply pieces are pre drilled which eliminates the need for onsite drilling, installers simply assemble to the desired form combination quickly and easily. Combine this with NUDURA’s innovative existing ICF panel system, custom form combinations and transitions between 90° and 45° are easily done. Once the job is completed all of the form ply panels can be stripped, cleaned and reused for the next job, eliminating waste and further cost.

For testing certain wall assemblies, the 2012 International Building Code (IBC) requires National Fire Protection Association (NFPA) 285, Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-load-bearing Wall Assemblies Containing Combustible Components. (That standard’s title notwithstanding, the test is performed on both load-bearing and non-load-bearing wall assemblies.) Its successful completion demonstrates the ability of an exterior wall mockup to contain vertical and horizontal flame spread across the face and through the wall’s core. Continue reading
Whenever we do readership surveys, the Failures column consistently ranks as one of the most popular parts of The Construction Specifier. Over the years, Deborah Slaton and David S. Patterson (along with many guest authors) have used the magazine’s final page to delve into what went wrong with a building, and explore how it could have been prevented. Continue reading
In addition to the HVAC Duct Construction Standard—Metal and Flexible manual, Sheet Metal and Air-conditioning Contractors’ National Association (SMACNA) has developed an app for designing ducts. It includes information regarding options for rectangular ducts with dimensions up to 3048 mm (120 in.) for applications from negative to positive 254-mm (10-in.) water gage as described in the print manual. The most common installation options are included as part of the app, but it is intented to be used in combination with the manual, an American National Standard (ANSI). The app is available for purchase for both Android and iOS. For more information, visit www.smacna.org.
