Product Description

Trulite Glass & Aluminum Solutions’ unitized pre-glazed system is available in non-thermal CG330 version, single thermal CT331, and high double thermal performance CT332 configuration. The system is engineered to provide simple fabrication, easy pre-glazed unitized assembly setup, and problem-free field installations. The system can be glazed with a 1” insulated glazing infill. Trulite’s 200, 300, & 500 entrances are easily integrated into this system.

Applications

The CG330/CT331/CT332 Series is ideal for commercial, retail, and institutional projects where narrow framing and pre-glazed efficiency are priorities:

  • Retail and office storefronts – Slim 1¼″ profile showcases more glass, creating a modern, transparent façade.
  • Schools, municipal, and government buildings – Offers dependable structural performance for civic facilities and educational environments.
  • Healthcare, hospitality, and mixed-use projects – Provides reliable performance and aesthetics for entrances, interior divisions, and exterior walls.
  • Fast-track construction – Unitized/pre-glazed option speeds installation for new construction or retrofit projects.

Features

  • 1¼″ × 4-1/2″ Narrow Framing – Highlights the glass appearance for a sleek, contemporary look.
  • Available Configurations – CG330 (non-thermal), CT331 (single thermal break), and CT332 (double thermal break) to suit performance needs.
  • Unitized/Pre-Glazed Option – Ships pre-assembled and pre-glazed to reduce jobsite labor and installation time.
  • Exterior Heel-Bead Silicone Sealing – Prevents water infiltration; does not require sill flashing.
  • High-Performance Thermal Breaks – CT332 double thermal break utilizes enhanced isolation for superior energy performance.
  • Premium Finishes – Architectural Class I and II anodized coatings or AAMA 2604/2605 high-performance organic finishes for long-lasting aesthetics.
  • Single-Source Compatibility – Integrates seamlessly with Trulite entrances, curtain walls, and accessories for a complete building envelope.

Performance

  • Air Infiltration (ASTM E283) – Does not exceed 0.06 cfm/ft² at 6.24 psf static pressure.
  • Water Resistance (ASTM E331) – No uncontrolled water infiltration at 15 psf.
  • Structural Performance (ASTM E330) – ±35 psf design pressure; maximum allowable deflection of L/175 for spans up to 13’-6” and L/240 + ¼” for greater spans.
  • Thermal Performance – U-factor of 0.37 Btu/hr-ft²-°F for CT331 (single thermal) and 0.33 Btu/hr-ft²-°F for CT332 (double thermal).
  • Condensation Resistance (AAMA 1503) – CT332 achieves CRF ratings of 63 (frame) and 65 (glass).
  • Acoustic Ratings (ASTM E90) – STC = 32; OITC = 26 for effective sound attenuation.
  • Thermal Movement – Accommodates temperature swings up to 180°F (82°C) without compromising seals or structural integrity.
