SPOTLIGHT METAL CONSTRUCTION ASSOCIATION IMPs Provide Proven Thermal Performance. The chemicals react and expand to create a rigid cellular foam that fills the cavity and fuses with the metal skins. This eliminates interior cavities and provides consistent insulation values throughout the panel. The finished product is a complete insulated panel with R-values that range between R-14 and R-48, depending on the core thickness and mean core temperature. Normally, insulation placed within a building’s stud cavity can be as little as 33 percent effective. In contrast, IMPs can provide up to 95 percent thermal efficiency. This high level of performance in the field is verified by the IMP’s compliance with ASTM C-1363-05 dealing with thermal performance and ASTM C 518 related to steady-state thermal transmission properties (www.astm.org). IMPs also protect the building’s interior and exterior and reduce airflow in and out of the building envelope, which helps improve HVAC performance. This enhancement may potentially contribute up to 10 points for Optimized Energy Performance if the building is aiming for certification in the USGBC’s voluntary LEED guidelines. IMPs also help the environment by reducing or eliminating field cutting and material waste. One Multi-Powered Unit Although individual products have slight variations, all IMPs typically consist of an insulated core, exterior and interior metal skins, double tongue-and-groove joinery, and concealed clips and fasteners. They are ideal for the entirety of an exterior wall or roof system but can also be used in conjunction with other panels for multi-component solutions. Regardless of climate conditions, IMPs offer the long-term durability and low maintenance offered by metal. The highperformance coatings applied to the metal skins protect the panels from exposure to sunlight, wind and harsh weather elements for decades, maintaining the aesthetic values and eliminating repainting. Architects and building owners are turning to IMPs for the panels’ proven thermal performance. But they also appreciate the benefits of a wide range of color and style options to fit all types of designs and the reduced installation time compared to multi-component assemblies that require trade groups for each component.

Proven Performance Insulated Metal Panels (IMPs) have proven to be sturdy, time-saving building elements in roof and wall applications for more than 30 years. The growing interest in improving building performance has brought IMPs to the forefront as a solid solution to making the best use of resources in designing and operating a building. Thermal Efﬁciency IMPs were one of the first exterior wall systems to place insulation outside of the support system while maintaining or improving thermal performance. IMPs are installed out- side the metal stud cavity or other structural support mechanism. This minimizes thermal bridging while efficiently incorporating a water, air and vapor barrier using a single-unit wall assembly that eliminates the need for other materials and construction trade coordination. The panels have a proven record of meeting new performance standards related to improved energy efficiency prescribed by ASHRAE 90.1. Many IMP products are produced via a state-of-the-art and highly efficient continuous bonding technology. During this manufacturing process, a liquid mix of pre-formulated chemicals is injected between two metal sheets. 44 ed+c J A N UA R Y 09 http://www.astm.org http://www.insulatedmetalpanels.org
