The Gilman Brothers Company is one of North America’s premier manufacturers of foamboard products.  Founded in 1897, Gilman Brothers has been in business for over a century and continues to supply the signage, display, and graphics markets with quality materials and expert product knowledge. As one of the originators of foamboard manufacturing, the Gilman Brothers Company continues to propel themselves into the future thanks to their hard work, innovation, and celebration of progress.  

With a full line of foamboard products to choose from, Gilman Brothers has provided graphic arts professionals with the materials they need to create merchandise signage, advertisements, art, displays, and exhibits. Gilman Brothers offers a variety of materials, but their most popular products include INFINITY® Styrene Face Foamboard, InSite® Reveal® Clay-Coated Paper-Faced Foamboard, and EAGLECELL™ All-Paper Honeycomb Graphics Board.

The Gilman Brothers’ INFINITY styrene faced foamboard features a smooth styrene surface for efficient and clean printing. The INFINITY foamboard can also be cold bent and wrapped around a pole and is optimized for many signage and display applications.

The Gilman Brothers’ InSite Reveal clay-coated paper-faced foamboard is a high-quality material with a proprietary foam center that was specifically designed to retain its thickness. The InSite Reveal paper-face foamboard also features a smooth, bright white paper with moisture resistant clay-coating for exceptional ink and color gloss.

The EAGLECELL all-paper honeycomb graphics board is an all-paper honeycomb board with triple-thick bright white clay coated liners. The EAGLECELL’s 100% fully recyclable paper core and surface papers feature an open core design engineered with 95% open space, making it lighter without compromising structural strength, rigidity, and warp resistance.
