BioClimatic Structures is the exclusive distributor of Solisysteme pergolas in the U.S. The “Bioclimatic” model (shown) features adjustable aluminum louvers that block sunlight and keep out rain. Custom-sized modules can be freestanding or installed next to an existing structure, the company says. Aluminum parts come in several colors and are treated for UV and weather resistance. Moving parts have a 3-year warranty; aluminum blades and structural parts have a 10-year warranty. A 10-by-10-foot motorized Bioclimatic pergola costs about $8,000 and will be available starting in July. BioClimatic Structures, 973.513.7016,
