Extech Inc. has introduced its TechVent® top-hinged windows, which the company says provide massive natural light and ventilation, doing everything that a louver can do at a lower cost. Available in continuous or individual units, these windows can be left open during normal rainfall. When glazed with cellular polycarbonate they also provide exceptional insulating value and resistance to impact and other abuse, according to the company. Rack and pinion operating hardware is durable and remote operators are available.
