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 OnceSince 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 TapeExtend 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 HookThe 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).

16mm RDC Storm Panels are engineered from multiwall polycarbonate to provide reliable window and door protection for commercial businesses and homes during severe weather and active hurricane seasons. Designed as a lightweight yet durable alternative to traditional storm shutters, these panels allow natural light transmission while shielding windows and doors from high winds and flying debris. They are a popular choice for coastal environments and regions with frequent storms. Important Notice: All sales on twinwall panels are final. No returns or refunds will be accepted once the material ships. For volume orders and custom shipping inquiries, please contact our sales department at 888-768-5759. This 16mm multiwall polycarbonate storm panel is engineered specifically for storm mitigation and opening protection. Unlike standard corrugated plastic or multiwall options, it has undergone rigorous testing under Miami-Dade County NOA protocols. It is the correct choice if you require: While both materials utilize polycarbonate engineering, they are rated for different structural demands. This lightweight material is designed for practical handling and installation using appropriate job-site tools. When preparing panels, follow the approved installation documentation for panel sizing, hole placement, substrate requirements, fastener type, and fastener spacing to maintain applicable wind and impact performance ratings. Performance ratings depend on approved installation methods, substrate conditions, fastener spacing, panel size, and local code requirements. Always review the current NOA and installation documentation before specifying or installing storm panels. Multiwall Polycarbonate for Severe Weather Protection
