Insulated Metal Panels (IMPs – SIPs)
4evr Homes LLC, the parent company of Carolina Log Homes, offers construction with insulated metal panels as an alternative to the log and timber frame/SIP building systems available through Honest Abe Log Homes.
A Modern, Efficient Building System
Insulated metal panels (IMPs – SIPs) are a high-performance construction solution used for both interior and exterior walls. Each panel is made by bonding a durable metal surface to a rigid insulating foam core, creating a unified barrier against heat, cold and moisture. Available in various widths, these panels are ideal for structures that require energy efficiency and environmental control.
Why 4evr Homes Chooses PermaTherm Panels
4evr Homes LLC uses insulated metal panels manufactured by PermaTherm, a U.S.-based company that has specialized in these systems since 1987, because because they offer long-term reliability and outstanding thermal efficiency. Over the years, PermaTherm’s panels have been integrated into a wide range of construction projects across multiple industries, known for their adaptability and dependable performance.
We’ve seen firsthand how well this system performs, both in cost and quality. The panels provide one of the lowest cost-per-R-values available, which means you’ll see savings on energy bills without compromising on performance. We trust these panels not just for their insulating power but also because they’re backed by decades of engineering and real-world application.

Benefits of Insulated Metal Panels
Energy Efficiency and Performance
Insulated metal panels (IMPs – SIPs) are a high-performance construction solution used for both interior and exterior walls. Each panel is made by bonding a durable metal surface to a rigid insulating foam core, creating a unified barrier against heat, cold and moisture. Available in various widths, these panels are ideal for structures that require energy efficiency and environmental control.
The insulated metal panels used by 4evr Homes offer exceptional thermal resistance and help prevent unwanted air infiltration. Their high insulation value means better energy efficiency at a lower cost per R-value than many other options. This makes them a smart choice for clients looking to balance performance with long-term savings.
Easy Installation and Structural Reinforcement
A key benefit of this system is its simplicity during installation. Thanks to PermaTherm’s z-lock joint design, these panels interlock cleanly and securely, creating a smooth, continuous barrier. Beyond energy efficiency, these panels also enhance the strength and rigidity of the overall structure, adding value and durability to your build.
When you choose 4evr Homes, you’re not just getting access to premium materials—you’re getting expert guidance, thoughtful customization, and a commitment to long-term performance. We’ll work with you every step of the way to design interior partitioning solutions that are efficient, attractive, and built to last.
Customizable and Greenguard Gold Certified
Every build is different, which is why we offer a wide range of panel sizes, finishes, and core options to suit your vision and performance needs. All panels used by 4evr Homes meet GREENGUARD Gold certification standards, meaning they contribute to healthier indoor air quality and meet strict chemical emissions limits.
By sourcing our insulated metal panels through a single trusted manufacturer, we streamline your construction process and eliminate the need for third-party coordination. You get the benefits of premium materials and expert guidance—all in one place.
Custom Metal SIP Home at Old Fort
This metal SIP home, designed and built by Rich Melius, is a showcase of comprehensive new construction. The exterior features log siding, while the interior is finished in tongue and groove. European doors and windows add to the home’s visual appeal. Among the highlights are a semicircular staircase with Mountain Laurel twig art crafted by Rich M and a closet equipped with a 30-foot electric rotating closet rod. To evaluate the energy efficiency of the metal SIP construction, a blower door test was conducted.
IMP-SIP Interiors
Ideal for Interior Partitioning and Environmental Control
One of the key advantages of insulated metal panels is their flexibility. They’re perfect for creating interior partitions within a structure, allowing for clearly defined spaces with independent environmental control. Whether you’re dividing a large open area or creating specialized zones within your home or facility, this system gives you precise control over temperature and moisture levels across different rooms—all within the same building envelope.
Custom Interior Partitioning with Structural and Thermal Benefits
At 4evr Homes LLC, we rely on insulated metal panel systems that offer both flexibility and performance – especially when it comes to interior partitioning. The panels we use, manufactured by PermaTherm, are strong yet lightweight and can be installed quickly and efficiently. They attach easily to existing structures and come in thicknesses ranging from 2 to 10 inches, giving us full control over the insulation value based on the specific needs of your project.
Whether you’re dividing up interior spaces in a custom home or planning for a controlled environment within a larger facility, we offer engineered panels in a variety of sizes, finishes, and insulation types. Our team can help you select from a range of exterior skins—including stainless steel, galvanized steel, and standard steel—and core materials like PermaTherm’s proprietary EPS and mineral wool.
IMP-SIP Exteriors
A Smart, Efficient Exterior Wall System
At 4evr Homes LLC, we integrate exterior insulated metal panels into our construction systems to deliver outstanding energy performance and lasting value. These panels, manufactured by PermaTherm, feature a durable metal surface bonded to an expanded polystyrene (EPS) foam core. The result is a high-performance wall system that is lightweight, strong, and easy to install.
Designed for both residential and specialty structures, this system offers exceptional thermal insulation and long-term durability, making it a smart alternative to traditional wall assemblies.
Energy Efficiency That Lasts
Energy efficiency is at the heart of the building solutions we offer. The insulated exterior panels we use maintain consistently high R-values that don’t degrade over time—ensuring your home or facility stays efficient for decades. With one of the lowest cost-per-R-values available, these panels are not only a sound environmental choice but also an excellent financial investment.
Panels are available in multiple thicknesses, from 2 to 10 inches, allowing us to tailor the insulation level to your specific climate or structural needs. The continuous laminating process used during manufacturing allows for precise customization, ensuring that every project gets the right fit and performance.
Quick Installation and Seamless Integration
Thanks to PermaTherm’s innovative z-lock joint system, our exterior insulated panels snap into place using a tongue-and-groove design that ensures a secure, continuous seal. This tight connection reduces thermal bridging—a common issue in traditional framing—resulting in more consistent indoor temperatures and reduced energy loss.
Beyond thermal control, these panels add strength and rigidity to your structure. Their easy installation saves both time and labor costs during the build, allowing your project to move forward efficiently without sacrificing quality.
