Green Roof The 1,000-square-foot vegetated roof consists of 2-foot-by-4-foot trays filled with growing medium and a selection of sedums chosen especially for the location and conditions.

Window Flashing VaproFlashing, Factory Formed Corners, and VaproSillSaver are engineered to prevent moisture intrusion around windows and doors. 3D Factory Formed Corners are manufactured using a patented breathable membrane fabric with each corner formed using an ultra-sonic welding process; this eliminates weak joints compared to traditional heat welding, which can cause problematic leaking, says the firm. The flashing is pre-cut for easy installation. VaproSillSaver slopes 1/8 inch back to front to allow water runoff. The sills are compatible with most flashings and vinyl, wood, and aluminum windows and doors, and they are 100% recyclable. 866.731.7663. www.vaproshield.com.
