Insulated & Rainscreen Porcelain Siding - Plank & Large Format Panels

US Patent #8,176,701 B2 ---- Canada Patent #2,588,294 & Other patents pending

The CRX Series Rainscreen is our most economical Porcelain Siding Panel. It is not insulated but has a 1\2" interlocking honeycomb rainscreen drainage backing. It is fast and easy to install and fits to windows and doors easily (it is 7/8" overall thickness). CRX attaches with staples or screws. Also, great for interior applications.

The C-Series Insulated is our Premium Insulated Porcelain Siding Panel system. It is available in R-10 & R-21 series. The thick, dense foam reduces noise and super insulates the walls over the studs which nearly doubles the stated R-value when compared to "cavity insulation" alone.
C-Series attaches with staples or screws.

The C-Series XL are Insulated or Rainscreen Large Format porcelain panels up to 24" x 126" mounted on the interlocking 2" R-10 or the 4-/1/4" R-21 foam panels. Large format is available in several standard sizes. It is commonly installed vertically but can be used horizontally or diagonally. All CastleRock Systems attach with staples or screws per our installation Guide.

InsulStone by CastleRock is available in an insulated version up to R-21 or a non-insulated version CRX Rainscreen. The CRX is less expensive & eliminates the need to install wood slats to the studs to space siding away from the wall to protect against moisture intrusion in the framed wall. Both styles are available in the stone colors below:
