Boltaron introduces Rigiwall 4333 Class 1-A sheet, a protective interior wall covering. It is a proprietary calendered PVC/Acrylic alloy developed as a protective interior wall covering for commercial and institutional buildings, including hotels, commercial and government offices, schools and retail stores. Rigiwall 4333 can be adhered to interior walls or pre-laminated to MDF and other substrates to create high performance composite sheet products. It can also be post-formed, thermoformed and machined using conventional tools to produce corner guards, crash rails, base moldings, profile moldings, self-supporting panels and other parts. The material has an Izod impact rating of 15 ft. lbs/in. (795 J/m), says the company.
