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. Available in "Flush or Lap" siding styles. It is fast & easy to install and fits to windows and doors easily (it is 7/8" overall thickness). CRX attaches with staples, nails 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. Available in "Flush or Lap" siding styles. The thick, dense foam reduces noise & super insulates the walls over the studs which nearly doubles the stated R-value of "cavity insulation" alone. Attaches with staples or screws.

The C-Series XL are custom size Insulated or non-insulated Rainscreen porcelain panels up to 24" x 126". Panels are R-10 to R-21 insulation rated. Panels can be installed vertically, horizontally or diagonally. Panels attach with staples or screws directly to the sheathing, even Type X Gypsum. See installation Guide for details.

InsulStone by CastleRock is available in an insulated version up to R-21 or a non-insulated version CRX with a built-in Rainscreen to prevent moisture intrusion into the wall cavity. Natural stone fascia never fades, discolors or warps. Both styles are available in the stone colors below:
