Dura-Foam is a lightweight closed-cell, free foam, rigid PVC sheet. It is homogeneously colored with a matte finish that is tough and versatile enough for many of today's applications. Dura-Foam is available in 12 standard vibrant PVC color sheets, plus black and white, and a variety of thicknesses and sizes to fit most uses. The matte surface is the perfect substrate for screen printing, painting, laminating, vinyl lettering and forming projects. Dura-Foam can be sawed, drilled, bent and fabricated using ordinary (plastic) tools and fasteners. Dura-foam is manufactured to be used for interior and limited exterior applications. Please use caution when using Dura-Foam in an exterior application, especially when dark paint, ink or vinyl is applied. This may cause the sheets to expand in heat and contract in cold. Test before any production run. S&F Supplies does not recommend long term term/permanent use of Dura-Foam in exterior applications.
