Product catalog summary

Overview: The document provides detailed specifications and features of a series of architectural grade hung thermal windows, specifically the Series 601 Single Hung, Series 6615 Fixed, and Series 6740 Fixed windows. These windows are designed for both historical replication and new construction projects, offering flexibility and energy efficiency.

Key Features:

Thermal Performance: The windows include a thermal barrier in the vent and frame to improve U-Factor performance, enhancing energy-saving potential.
Weather Resistance: Weather-stripped sash and sill provide superior air and water performance, while continuous interlock meeting rails improve air infiltration resistance.
Glazing Options: The windows accommodate glazing from 1/8" to 1" depth, offering flexibility in design and energy-saving options. Inside or outside glazed sash allows for design flexibility.
Convenience and Durability: Features like automatic sash locks and extruded aluminum alloy screen frames enhance convenience and durability.
Customization: An accessory line of subframes, mullions, and architectural sills allows for custom designs with standard products. Anodized or painted finishes are available to meet economic and aesthetic concerns.

Performance Data:

AAMA Rating: H-AW70
Air Infiltration: Less than 0.30 CFM/sf at 6.24 psf
Water Resistance: No leakage at 12.0 psf
Condensation Resistance Factor (CRF): Frame - 44, Glass - 74

Construction Details:

Main Frame: Constructed of 6063-T6 aluminum alloy with a depth of 3 7/8" and a nominal material wall thickness of .080".
Sash Frame: Aluminum members with .080" nominal material wall thickness, featuring dual weather-stripped, continuous interlock for superior performance.
Thermal Barrier: Sills are thermally isolated with glass-reinforced polyamide nylon struts, and other frames and sash are thermally broken using high-density polyurethane.

Hardware and Glazing:
