Yes. CeilingMAX components are manufactured from durable PVC material and are suitable for outdoor applications. Some deformation may occur in extreme temperatures due to expansion and contraction of the components. We recommend using solid colors or our Argent finishes in an outdoor application. Foil-faced finishes are not recommended for outdoor use as corrosion from salts can occur. Please contact us at customersupport@acpideas.com for more information about appropriate finishes for outdoor use.
