The new performance window system (PRW) from Vistawall Architectural
Products, part of the Terrell, Texas-based Vistawall Group, was
designed for projects with punched or ribbon window openings that
require quick and easy installation.
According to a company press release, the PRW's preassembled
frame is designed to save time for the installer. The announcement
said the PRW has been tested to high levels of air and water performance
and includes many features such as secondary water control, molded
corner gaskets and dual-finish capabilities. The system offers
2 ¼-inch and 4 ½-inch framing for 1-inch glazing.
