Installed by Side-Pro Exteriors across Seattle, Bellevue and Tacoma
Swisspearl is an architect’s panel, sold to architects. If you are re-siding a house, we will tell you honestly whether it fits.
Swisspearl makes large-format through-colored fiber cement facade panels — the Largo range at 6, 8 and 12 mm — for ventilated rainscreen assemblies. The material is cement, cellulose, water, synthetic fibres and air, and the color is in the panel rather than on it.
The frost data is the figure that earns attention in this climate: 100 freeze-thaw cycles at a residual strength ratio above 0.75 under EN 12467. A panel on a Seattle or Bellevue elevation that crosses freezing a dozen times a winter is being asked precisely that question, and the answer is documented.
It is a commercial and architectural product first. Swisspearl’s North American site is written for specifiers, there is no residential lap siding line, and there is no homeowner product page at all. On a modern Tacoma or Seattle house with a designed facade it can be exactly right. On a conventional re-side it usually is not, and we would rather say that than quote it.
We install Swisspearl rainscreen assemblies on residential and commercial buildings across Seattle, Bellevue, Tacoma and the wider Puget Sound region.

Two cautions you should hear from us rather than find out later. Swisspearl publishes no warranty — its US download center carries technical data sheets, EPDs, installation manuals and approvals, and no warranty document at all. Where a warranty is quoted for Swisspearl it generally belongs to a North American distributor rather than the manufacturer, and those are not the same thing. And on biological growth, Swisspearl says only that the alkaline composition of the material resists it: no moss claim, no algae claim, no test standard. We are not going to upgrade that sentence on their behalf.
