The patented R-stud is the lightest, strongest, most cost-effective and energy efficient steel stud available on the market today. Its unique design and superior performance allows developers, architects, engineers and general contractors to produce a new generation of energy efficient and cost-saving structures. R-Stud wall assmbly cost comparison by STC.

R-stud minimizes upfront carbon emissions by employing efficient manufacturing processes and reducing material waste. This approach ensures that from production to installation, RStud products contribute less to the initial greenhouse gas footprint of building projects, promoting sustainable construction practices.

Higher Limiting Wall Height

R-stud’s have a higher limiting wall height than a generic steel stud of the same gauge/thickness. This translates into the ability of the designer to use either a lighter gauge R-stud than a generic stud or to space the studs at 24” on center instead of 16” on center. Simply enter the desired wall height and load factors into our on-line stud calculator, and see the difference between an R-stud and a generic (SSMA type) stud.

Better Thermal Performance

With more emphasis being put on building performance, R-stud is the only steel stud that provides a 40 percent reduction in thermal bridging over the generic steel stud. Download our thermal performance test conducted by RDH Building Sciences here.

Lower Sound Transmission

Acoustical tests prove R-stud’s performance to be significantly higher than generic steel studs. R-stud eliminates the need for extra layers of gypsum or resilient channel to attain STC (sound transmission class) This translates into lower cost of construction and because the wall assembly takes up less space (less gypsum and/or RC) there is more marketable square footage in the buildings that use R-stud.

More Sustainable

R-stud is eco-friendly from production through construction, emphasizing on sustainable design. R-studs are made from 34 percent recycled steel. They provide superior strength with thinner gauge steel, meaning 18 percent less raw material compared to a generic steel stud. When a generic steel framing stud needs to be 16” o.c., the R-stud allows for 24” o.c. Walls built with R-studs use less gypsum and still get better STC ratings than with a traditional steel framing stud.

Lean Construction

The use of the R-stud embraces the Lean construction approach. When R-studs are used on a building there are less studs needed to be delivered to the job site, walls are built faster due to less studs needed, less gypsum needed for walls and subs can install utilities faster because of the large supplemental flanges built into each stud. And there will be less wasted material to dispose or recycle.
