Good Sidings

“You don’t think of maintenance as a sustainability issue, but it is,” says Swatt, who points out that most exteriors require stain, paint, or sealant for upkeep. This house instead boasts a zero-maintenance facade made from concrete block, corrugated metal, and Parklex—a siding material from a company based in Navarre, Spain. Parklex is an amber-colored wood, yet, because it is a thin veneer set in resin on top of an engineered panel core, it doesn’t require any scraping, painting, or sealing. If the siding ever does need cleaning, a pH-neutral soap-and-water solution and a mop will do the trick.  Photo 7 of 8 in What Would Eichler Do?
