Kalwall translucent sandwich panels can add aesthetically pleasing and sustainable elements to any commercial design. In a recent installation, the Kalwall wall system efficiently served as a heat insulator. The company’s wall systems include translucent panel wall applications that are for a single story or less and do not integrate fixed or operable glazing units or louvers. Structural sandwich panels, up to 5 feet by 20 feet, may be either flat or curved. In addition, sizes may be customized to accommodate a variety of head and sill conditions.
