Backers Brown .011 Thick 25 x 97 Inch identifies this Richwood Industries PolyBak sheet as a thin, brown backer sized for larger panels, so it can cover significant surface area in a single piece and help reduce seams across the back side. The PB42BR28 2X8 designation ties this sheet to the PolyBak PB42 line, which is presented as a great choice for a low cost balancing backer or paintable overlay, giving shops one product that can serve both as a stabilizing layer and as a surface ready for finishing. Being part of the Richwood Industries Backers class places it within a family of products intended specifically for balancing substrates faced with wood veneer and decorative laminates, which supports predictable panel performance in those applications. The SAP description POLYBAK(.011) 25' X 97' BROWN reinforces the thickness, size, and brown color, which all matter when matching backers to visible faces in a job.
The .011 inch thickness called out in the product name defines this PolyBak backer as a thin sheet, which helps it function as a balancing layer without adding significant bulk to the panel build-up. The 25 x 97 inch size reported in both the product name and SAP description means the sheet spans over eight feet in one direction, which supports covering tall casework sides, doors, or other large components with a single cut. The brown color noted in both the product name and SAP description provides a consistent appearance on the non-show face, which matters when back sides may be visible in open installations. As a member of the Richwood Industries Backers category, this sheet aligns with common fabrication workflows that rely on backers behind wood veneer and decorative laminates.
The web description states that a common use for PB42 is balancing substrates faced with wood veneer and decorative laminates, so this sheet fits well on the back side of panels where the front is finished with those materials and a counterbalancing layer helps maintain flatness. Another listed common use is MDO for concrete forms and other applications, which positions this PolyBak backer as suitable for use with medium density overlay panels in forming work and related jobs where a stable overlay is needed. PB42 is also directly described as a paintable overlay, which means it can be used where a back face or secondary surface will be painted instead of veneered or laminated, keeping the build-up simple while preparing the surface for a coating. As a Richwood Industries backer under the PolyBak name, it aligns with shop practices that rely on dedicated backer products to support consistent panel behavior across projects.
The description explains that PB42 has properties similar to the lower cost Poly Bak PGB but with even greater tensile strength, which provides added resistance when panels experience tension during handling, transport, or fastener pull, supporting long-term panel integrity. The same comparison notes greater moisture resistance than Poly Bak PGB, which matters when panels are exposed to variable humidity or incidental moisture, because the backer is designed to limit moisture-related effects compared with that lower cost option. Calling PB42 a great choice for a low cost balancing backer highlights that it was positioned to deliver these strength and moisture advantages while still supporting budgets, which is useful when specifying material on multi-panel runs. Identifying the sheet specifically as POLYBAK(.011) 25' X 97' BROWN links its performance characteristics to a defined size, color, and thickness, making it easier to match repeat jobs around that balance of strength, moisture behavior, and cost.
The Backers Brown .011 Thick 25 x 97 Inch product is described as a great choice for a low cost balancing backer or paintable overlay, so it serves as a stabilizing and finish-ready layer on panel backs.
PB42 is specifically listed for balancing substrates faced with wood veneer and decorative laminates, so it provides a counterbalancing layer on the reverse side to support stable, flat panels.
The description notes that PB42 has even greater tensile strength and moisture resistance than Poly Bak PGB, which supports improved performance under tension and in humid or moisture-exposed environments.
The .011 inch thickness identifies PB42 as a thin backer, which adds minimal build to the panel while still providing the balancing and overlay functions described in the product information.
The 25 x 97 inch size lets the sheet span long or tall components in one piece, which reduces joints across the back face and supports faster layout for larger panels.
PB42 is directly described as a paintable overlay, so it is intended to provide a surface that can be painted when a back face or secondary surface requires a coating finish.
The Richwood Industries PolyBak PB42BR28 2X8 sheet combines a .011 inch thickness with a 25 x 97 inch size and brown color, giving panel shops a defined backer format to pair with wood veneer and decorative laminate faces. Its description as a great choice for a low cost balancing backer or paintable overlay, along with its greater tensile strength and moisture resistance compared to Poly Bak PGB, presents a clear performance and budget profile. For projects that call for balancing substrates, MDO for concrete forms, or a paintable overlay surface, this PolyBak backer offers a consistent, documented option to specify across similar runs and repeat jobs.
