FAQ

What sizes do NRG panels come in?
NRG panels are specifically designed for each project and panel sizes vary depending mostly on door and window sizes. NRG panels generally uses eight foot widths for ease of shipping and erection, but it is often necessary to produce larger panels for larger openings.

What is included with the NRG system?
The NRG system starts with the panelization of your project, using our proprietary computer software. Additional engineering may be required depending on the project size and it may be necessary to contact the project engineer. Details for tie down and J-bolt locations are supplied as well as all erection instructions. Panels are delivered to the job site with all track, over track connectors and screws.

Can NRG walls be made in any height?
Yes. Since NRG used the guidelines outlined in the 2003 International Residential Code (IRC), walls will be assembled to the specified requirements. For example, stud spacing for a tall wall carrying a heavy load for a large roof span may require 16 inch spacing, as required by the 2003 IRC.

How are NRG panels wired and plumbed?
The NRG system makes plumbing and wiring simple. Channels are placed in planels for running all wiring in exterior walls. This makes wiring an NRG home easier than wood since electrical contractors no longer have to drill through each stud to run wiring. Plumbing allowances are made in NRG panels at locations specified in the projects plumbing details.

What gauge of steel is used to build NRG panels?
Standard NRG panels are assembled using 20 gauge structural steel components. For larger spanning headers and some taller walls, heavier gauge steel is used.

Will a house made with steel rust?
No. NRG panels are made with F-90 galvanized steel. This galvanizing process makes the steel resistant to rust.

Does the Styrofoam used to insulate panels emit harmful gases?
The NRG Styrofoam that is used is manufactured to strict guidelines outlined by the IRC with the use of their ICBO standards testing. All Styrofoam is graded to be used for insulation in wall cavities and is treated to eliminate any off-gassing.

How are trusses attached to panels and do trusses need to be made with steel?
Trusses are attached to the NRG panel system using the method specified by the design. This means that all hardware and strapping components will comply with engineers’ specified hardware. Trusses do not need to be constructed with steel; however the attachment detail for wood to steel attachment must be followed.

How are NRG walls finished?
NRG walls are easily finished with any material that can be used on traditional wood framing. Finishes are attached using self-tapping hardware, such as self-tapping drywall screws.

Can I install NRG panels or do I need a contractor to install them?
The NRG panel system is so simple that anyone can put it up, it is necessary to follow all instructions carefully, and a framing inspection will still be necessary, but erecting NRG walls yourself can save valuable time and labor cost.

Is permitting more difficult when using the NRG panel system?
Since NRG is the only panel system that uses the guidelines outlined in the 2003 IRC, permitting is much easier than with other panel systems. It may still be necessary to perform additional engineering for special attachments, but generally the 2003 IRC guidelines will outline these attachments.

Will my home look different than the rest in my development?
No, once a house is finished, there is no difference between a steel home and one built with wood, in fact the steel home will remain straight and true long after the wood house has warped over time
