High Performance Backer 0.24 inch is a Poly Bak PB90 sheet designed as a high-strength backer for laminated substrates and as a paintable overlay for substrates and columns. The 0.24 inch thickness gives a consistent profile behind decorative laminate, which helps projects keep a uniform build across panels. The 61 x 145 inch size covers large surfaces in a single sheet, reducing seams on wide casework or tall column wraps. Being 3.5 times stronger than a leading saturated Kraft paper backer of the same thickness, this Poly Bak PB90 backer supports demanding commercial or shop environments where panels are handled repeatedly. As part of the Richwood Industries backer line, it fits into standard woodworking workflows that pair decorative laminate on the face with a stable backer on the reverse.
This 61 x 145 inch Richwood Industries backer sheet is sized to work across full-height panels and wide runs, so fabricators can plan cuts with fewer offcuts on large projects. The 0.24 inch thickness pairs with laminated substrates, supporting assemblies where the backer build must match the face material more closely. Because Poly Bak PB90 is designated as a backer for laminated substrates, shops can route it into the same pressing or bonding steps as their face laminates. When used as a paintable overlay on substrates or columns, the full sheet format helps installers wrap or skin surfaces in single pieces before trimming, cutting down the number of seams that need finishing.
The High Performance Backer 0.24 inch from Richwood Industries is described as most commonly used as a backer for laminated substrates, so it fits projects built around decorative laminate panels. In cabinet or casework runs, one 61 x 145 inch sheet can back tall partitions or oversized ends, giving the reverse side a consistent surface. On wall panels or fixtures, the full sheet format supports layouts where the laminate face and backer run in parallel during pressing. As a paintable overlay for substrates and columns, this Poly Bak PB90 backer serves in column wraps and other vertical elements where a paint-ready skin over a structural core is required.
The Poly Bak PB90 formula is stated to be 3.5 times stronger than a leading saturated Kraft paper backer of the same thickness, which helps panels stand up to fabrication, transport, and installation stresses that can otherwise affect flatness. The 0.24 inch thickness aligns with the thickness of comparable paper backers, letting shops treat it as a direct substitute where additional strength is valuable. Because it is intended both as a backer for laminated substrates and as a paintable overlay for substrates and columns, one material can serve across different parts of a project, simplifying material handling and inventory. The 61 x 145 inch dimension allows fabricators to nest multiple cabinet parts or column sections from a single sheet, which supports repeatable layouts from job to job.
High Performance Backer 0.24 inch is most commonly used as a backer for laminated substrates, giving the reverse side of laminate panels a stable backing layer.
The Poly Bak PB90 backer sheet measures 61 x 145 inches, which lets fabricators cover large panels or multiple parts from a single sheet.
