An opening solution for ICF, composed of LSL that allows for direct contact with concrete.
Engineered for the purpose of attaching wood floor joists or for the seamless connection of wood roofs to structures utilizing the Nudura XR35 Form
Nudura XR35 Insulated Concrete Forms (ICF) redefine the standards of building efficiency and resilience. Manufactured from Expanded Polystyrene (EPS) foam, and high-density polypropylene plastic, this cutting-edge flat wall system, with its 4" (102 mm) thick EPS panels on each side of the form, achieves an impressive R-Value of R-35, optimizing energy efficiency and reducing heating and cooling costs. Designed to withstand disasters, Nudura XR35 meets critical building codes, ensuring durability without compromising on thermal performance. Ideal for quick and easy on-site interior or exterior fastening, Nudura XR35 is the ultimate choice for sustainable and robust construction projects.
Best for:The innovation continues with our XR35 Plus Series form. With its 4-inch (102mm) EPS panels, the XR35 delivers an unprecedented R-Value, making it a game-changer for efficiency and insulation.

Our Fastening Strip utilizes a reversible triple tooth interlock mechanism to firmly secure forms in place, effectively preventing float and compression without the need for wiring forms together. Our Duralok design includes embedded web/fastening strips that span the entire 18-inch (457 mm) height of each web. This ensures that the ICF forms remain uncompressed during concrete placement and offers a continuous, industry-leading fastening strip for finish materials.
Our Hinged Web allows Nudura ICF Products to be shipped flat, allowing for 40% more product on a truck compared to other ICF manufacturers. Simply unfold and stack.
Nudura Standard Forms are the longest standard Insulated Concrete Form in the industry allowing the placement of 12 square feet (1.11 m²) of the wall area in one building step. Building with Duramax Technology® results in faster installation times, less waste and a reduced amount of seams.
The forms interlocking design allows it to be four-way reversible, significantly reducing waste by eliminating the need for distinct left and right corners. This adaptability allows Nudura Insulated Concrete Forms to be utilized in twice as many construction scenarios compared to non-reversible forms.
