As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Advanced Multiwall Cladding: The Rigid Alternative to FRP
Duraclad™ interlocking PVC liner panels are made for environments where standard thin-sheet liners fail. Their specialized 1/2" thick multiwall structure delivers superior structural strength and rigidity compared to standard single-wall PVC liners and fiberglass reinforced panels (FRP).
Designed as a rugged, installer-friendly alternative to traditional FRP and drywall, these panels provide a lightweight yet exceptionally tough solution for moisture-prone and demanding interior environments.
Duraclad™ utilizes thicker inner walls to resist impact and prevent bowing, all while maintaining a smooth, high-gloss finish. It is a great choice for facilities requiring a 100% waterproof, hygienic surface that is virtually maintenance-free.
Duraclad™ is the ideal choice for high-moisture agricultural and industrial cladding. Unlike thin, single-sheet liners, Duraclad's multiwall design ensures:
Zero-Exposure Fastening: The interlocking tongue-and-groove system features a pre-slotted nailing flange. This hides all fasteners behind the face of the next panel, creating a flush, fastener-free surface that prevents bacteria buildup and simplifies high-pressure power washing.
Sanitary Excellence: Its non-porous surface is inherently resistant to bacteria, mold, and mildew, meeting FDA/USDA requirements for walls and ceilings.
Extreme Chemical Resistance: Engineered to withstand harsh cleaning agents, industrial chemicals, and corrosive gases emitted by animal waste.
ASTM Class A Fire Rating: Certified non-flammable with a Class A fire rating (ASTM E84-17a)—suitable for a wide range of regulated commercial structures.
Expansion-Ready Design: Unlike glued FRP, which can crack or delaminate during temperature swings, Duraclad’s mechanical fastening system "floats," allowing for natural thermal expansion and contraction without compromising the seal or structural integrity.
Duraclad™ vs. Traditional FRP: Which Do You Need?
While both materials are used for sanitary wall cladding, Duraclad™ offers distinct advantages in installation and longevity.
Choose Duraclad™ (This Panel) for faster, cleaner installations. It requires no messy adhesives or trim-heavy transitions and offers better impact resistance due to its internal rib structure.
Choose FRP for low-clearance areas where an ultra-thin profile is required. Note that FRP often involves adhesives and visible fasteners for proper securing/bonding.
Installation & Accessories
Duraclad™ is designed for efficiency, installing directly onto wall studs or over existing surfaces. For optimum performance, use color-matched installation accessories. Components like J-Trim, H-Dividers, and Inside/Outside Corners are designed to house the panel edges for a fully water-tight and professional seal. This material can be cut and drilled using standard woodworking tools.
When you order from Interstate Plastics, you're accessing an expansive nationwide network of material expertise. Interstate Plastics sources Duraclad™ directly from the manufacturer, ensuring you receive genuine, Made in the USA panels that meet strict RoHS and lead-free compliance standards.

Technical Performance
Duraclad™ is an engineered multiwall PVC panel designed for interior environments requiring a combination of high structural rigidity, fire safety compliance, and a maintenance-free sanitary finish.
Structural Rigidity: Features a multiwall internal rib design with thicker inner walls than standard PVC liners, providing superior impact resistance and preventing panel bowing.
Fire Safety Certification: Rated Class A under ASTM E84-17a and CC1 under ASTM D635-74, meeting stringent building codes for commercial and industrial interiors.
Thermal Expansion Design: The specialized interlocking tongue-and-groove system is engineered to allow for natural material expansion and contraction without compromising the secure, hidden fastener seal.

Engineering Limitations & Alternatives
While Duraclad™ is the industry leader for multiwall PVC cladding, specific environmental factors may require alternative materials:
Operating Temperature: PVC is an interior-grade thermoplastic and should not be used in environments where continuous service temperatures exceed 140°F. Better Alternative: For high-heat industrial wash zones, consider stainless steel or high-temp composite cladding.
Profile Depth: At 1/2" thick, the multiwall structure requires more clearance than traditional thin-sheet liners. Better Alternative: For ultra-low profile needs in tight spaces, choose FRP (Fiberglass Reinforced Plastic).
UV Exposure: Standard Duraclad™ is designed for interior use. Prolonged direct sunlight exposure may cause discoloration or brittleness over time. Better Alternative: For exterior-facing applications, consider UV-stabilized Polycarbonate Multiwall Panels.
