Frame and Sash

• 3 mm (0.12 inch) thick RAU-PVC extrusions from REHAU.
• 60mm, four-chamber design in the sash and frame increase strength and reduce heat transfer.
• Pockets for galvanized steel reinforcement when additional strength is necessary.
• The extrusions and hardware are so strong that when steel reinforcement and appropriate glazing is used, Tilt & Turn Windows can reach performance levels comparable to a 172 mph wind speed for uniform load deflection and a 210 mph wind speed for uniform load structural tests.

Performance

• 4500 Series Tilt & Turn Windows come standard with your choice of two superior insulated glass packages – a high Solar Gain package featuring Cardinal LoE 180 glass or a low solar gain package featuring Cardinal LoE³ 366. Additionally, WASCO offers two high performance triple pane packages at fair prices -- the Comfort³ Triple Pane for the greatest comfort or the Sustainability Glass Package, with triple glazing and two layers of Cardinal LoE180 glass, provides for even greater energy efficiency, as it achieves a very low U-Factor while maintaining a good solar heat gain coefficient for Wisconsin's climate. WASCO uses the no-metal SuperSpacer® between the panes of glass for a warm edge. (Tempered and oversized units may be supplied with Cardinal XL-Edge® Spacer.) Supplied with three layers of double strength glass, this combination simply shuts out outside noise.
• 4500 Series Tilt & Turn Windows earn the EnergyStar® with dual pane glass and can achieve NFRC whole-window U-Factors below 0.20 Btu/hr•ft²°F with triple pane glazing.
