St. Cloud Window Inc. has introduced the SCW3000 Series, a line of historic replication/narrow sightline windows and terrace doors. The SCW3000 Series is designed around a 3-inch frame engineered to maintain a narrow sightline profile yet facilitate the structural needs of large window openings and maintain the historic integrity required for landmark properties. It is available for awning, hopper, casement and fixed applications, as well as floating vent fenestra- tions that are common in buildings of historic significance. The new window boasts 45 STC and 36 OITC (without the need for an acoustic interior panel) and thermal values ranging from 0.23 to 0.31 U values and 0.16 to 36 SHGC values.
