    Description

    PolyBak Ultra Veneer Backer For Stable Panels

    PolyBak Ultra veneer backer gives you a premium balancing backer that is stronger than phenolic and more water resistant, so veneered panels stay flatter under demanding conditions. The nominal 0.035 inch thickness creates a consistent backing layer that supports reliable panel construction across large surfaces. The 61 inch width pairs with the 97 inch length to cover common cabinet and fixture panel sizes in a single sheet, which helps reduce seams during layup. The brown color provides a neutral, professional-looking back face for casework and architectural panels. With an advanced performance level, this Richwood Industries backer supports projects that require more demanding moisture and durability performance than standard options.

    Key PolyBak Ultra Details That Save Rework

    • Being stronger than phenolic means the PolyBak Ultra veneer backer resists mechanical stresses behind the decorative face, which helps panels stay rigid and reduces the chance of telegraphing or distortion in service.
    • Greater water resistance than phenolic allows the backer to better tolerate elevated humidity or incidental moisture exposure, which supports panel stability in typical kitchen, bath, and commercial interiors.
    • The advanced performance level rating indicates this backer is engineered for higher-demand applications, helping installers match material choice to projects where panel movement control is critical.
    • The nominal 0.035 inch thickness provides a substantial yet workable backing layer, allowing fabricators to balance veneered panels while still fitting standard cabinet and furniture construction details.
    • The 61 inch standard width works well for wide cabinet sides and tall panels, so fabricators can back larger components without creating additional joints that might complicate pressing or trimming.
    • The 97 inch length suits many vertical and horizontal panel layouts on shop presses, which supports efficient yield when backing doors, partitions, and case components.
    • Availability in 1,800 lineal foot rolls gives production shops the option to run longer parts with consistent material, supporting repeatable results across multiple similar panels.

    Veneer Backer Dimensions That Support Workflow

    The 0.035 inch nominal thickness of this PolyBak Ultra veneer backer provides a predictable backing layer that aligns well with standard panel buildup practices, so finished thickness remains consistent from part to part. The 61 inch width reduces offcuts on tall or deep cabinets because many components fit across the sheet width without excessive trimming. The 97 inch length matches common full-size panel formats, which helps integrate this backer into existing press setups and cutting patterns. Together, these dimensions allow shops to balance veneered panels efficiently while maintaining the layout patterns already used for other sheet goods.

    Using PolyBak Ultra Backer In Cabinet Work

    Where This Veneer Backer Fits Best

    PolyBak Ultra veneer backer, with its advanced performance level and greater water resistance than phenolic, fits projects where panel stability is a priority, such as cabinet cases and interior architectural panels. The brown color gives the non-show face of panels a uniform appearance, which suits open cabinets or areas where backs are occasionally visible. The 61 inch width lets shops back tall pantry sides, wardrobe panels, and deep base cabinets from a single sheet, limiting seams in the balancing layer. The 97 inch length works well for typical casework heights and horizontal runs, supporting efficient cutting diagrams on panel saws. Because it is stronger than phenolic, this backer supports veneered faces in areas subject to everyday impacts and handling, helping the finished surface perform consistently over time. Availability in 49 and 61 inch widths and 97 and 145 inch lengths gives shops flexibility to match sheet size to their standard cabinet and fixture programs, which can improve material yield across different runs.

    Details That Support Repeatable Panel Results

    The nominal 0.035 inch thickness of the PolyBak Ultra balancing backer provides a consistent counter-balance for the decorative veneer on the opposite face, which helps control panel cupping once the panel is pressed and trimmed. Being stronger than phenolic means the backer contributes structural support across the full panel area, which can reduce localized deflection behind hardware or shelving loads. The higher water resistance supports dimensional stability when environmental conditions fluctuate, which is especially important for maintaining even reveals and door clearances in installed cabinetry. With lengths also available up to 145 inches, production shops can standardize on a single backer family for both standard and oversized components, maintaining the same performance characteristics across the job. Availability in long 1,800 lineal foot rolls supports high-throughput operations by reducing changeovers, so large batches of matching cabinets or fixtures can be balanced with the same material for consistent behavior in the field.
