Yes. URESTONE faux stone, faux brick, and faux wood panels can be used to clad most chimney chases and exterior or interior chimney surrounds when installed on a flat, stable substrate and when all clearances to combustibles, venting requirements, and local building codes are followed. The panels are made from high-density polyurethane, so they must not contact the flue, liner, or any surface that reaches elevated temperatures or has direct flame exposure.

Details

• Where they work: exterior framed chimney chases, interior chase surrounds, and existing masonry chimneys when you provide a flat substrate such as exterior sheathing, cement board, or furring over masonry

• Where they do not go: never on the metal flue pipe, chimney cap, crown, inside the firebox, or any surface defined as non-combustible by code or the appliance manufacturer

• Clearances: follow the fireplace, insert, stove, or chimney system manual for clearances to combustibles and respect all local building and fire codes

• Heat zones: within any manufacturer-defined hot zone, use Class A fire-rated panels or a non-combustible material as required. Class A increases fire and heat resistance but is not fireproof

• Weather resistance: panels have a durable, weather-resistant finish suitable for exterior use when properly sealed at penetrations and terminations

• Substrates: install over wood framing with sheathing, cement board, masonry with furring, or other approved vertical surfaces that are flat, clean, dry, and structurally sound

• Fastening: use construction adhesive plus corrosion-resistant screws. Maintain recommended screw spacing and follow expansion gap guidance

• Flashing and moisture: integrate with proper step flashing, counterflashing, kick-out flashing, and sealants where the chimney meets the roof or wall cladding

• Style continuity: large 4x8 panels reduce seams for tall chimney runs. Use keyless corners, narrow corners, end caps, and color-matched touch-up for a seamless stacked stone or brick look

• Maintenance: inspect sealant, flashing, and panels periodically, especially after severe weather

Quick planning checklist

• Confirm chimney type and venting system

• Identify manufacturer-required clearances to combustibles

• Decide where non-combustible borders or Class A panels are needed

• Provide a flat substrate and proper flashing details

• Order panels, corners, end caps, adhesive, screws, and touch-up kit
