Design Options

Wide Range Available

RIGIWALL® 4323 combines exceptional durability, the widest range of color and texture options and long service life in a wallcovering material for schools, hospitals, office buildings, hotels and other high traffic environments.

Available in thicknesses from 0.028 to 0.060 in. (0.7 to 1.5 mm), this proprietary thermoplastic alloy meets Class 1-A flammability requirements, and carries a UL 723 listing. Its high impact strength also resists damage from shopping and luggage carts, wheeled equipment, gurneys and wheelchairs.

RIGIWALL 4323 also helps maintain clean, attractive aesthetics even in damage prone areas. Its integral colors mask marring and scratches that visibly damage painted, laminated and printed materials. It also withstands sanitizing chemicals and strong cleaners needed for removing graffiti and scuff marks.

The material can be adhered directly to interior walls, mechanically fastened, or pre-laminated to substrates like MDF to create strong composite panels. It can also be thermoformed, post-formed and machined to make guards, rails and wall system components in matching and complementary colors.
