One of the many benefits of using insulated metal panels (IMPs) for commercial and industrial construction projects is the materials cost-effective one-pass installation.
IMPs, also known for their spanning abilities and exceptional insulation, are becoming an increasingly popular choice of building designers across the country.
Manufacturing, recreational, institutional and government buildings and facilities are utilizing IMPs architectural advantages and energy efficiencies in sustainable initiatives.
IMPs, roof and exterior wall panels composed of steel skins surrounding a highly insulating foam core, are the most common type of insulated panels in use today.
While the typical IMP installation will save your project on labor costs and expedite the building process, those benefits can be erased with installation mistakes.
Here are some common mistakes that are made with IMP installation that can cost your project both time and money:
In a perfect world you can order the exact number of panels to complete your project without any IMPs being damaged while in transit, stored on the job site or during the actual installation.
Those panels on hand can be installed very quickly with the Metal Construction Association in its “Selection Guide for Insulated Metal Panels” estimating that a four-man crew working an eight-hour shift can install up to 5,000 square feet of panels on an industrial project. An architectural project can be installed up to 1,100-square feet by the same size crew.
While the speed of installation is a bonus, projects can grind to a half when crews run short of material and must wait for more orders from the manufacturer.
It is not only important to have enough panels on-site to complete the project, but installers must have access to proper equipment to complete the job safely and efficiently.
Equipment, such as forklifts, must be available with sufficient capacity to handle the lifting, carrying, and setting of the IMPs. Smaller IMP bundles, for example, can be handled with one forklift but for larger IMP bundles, two forklifts are required.
Specific equipment made to handle IMP installation can include:
Not having the proper equipment on-site can lead to delays in installing IMPs and to damaging of the panels.

All IMPs come with extensive installation manuals for a reason – to help you safely install the panels on your project.
Green Span Profiles provides customers with two general guides as a starting point -- Insulated Metal Wall Panel Installation Guide as well as Insulated Metal Panel Handling and Maintenance Guide.
Familiarity can be a great thing when you have a contractor and crew with experience handling and installing IMPs. On the flip side, it is a mistake to assume that each application is the same and that way of thinking can lead to errors.
It is critical for installers to rely on the project’s installation drawings as each project can have different requirements for sealants, spacers, and fasteners.
Green Span Profiles guide says, “Always reference the project’s installation drawings for the specified requirements. If there are differences between the installation drawings and these installation guide details, the installation drawings will govern.”
Your project could avoid all the pitfalls covered above but still have problems when it comes to the structural support framing, which must be checked for straightness and alignment prior to IMP installation.
Framing alignment must be checked to verify that wall and roof panels can be installed without interference. IMPs installed on misaligned framing can lead to rippling or buckling which ultimately will require panels to be replaced.
When it comes to tolerance, Green Span Profiles says that “intermediate framing member’s alignment tolerances are as specified below:
Any misaligned framing must be addressed prior to the installing of IMPs.
