GWT-CRK100 Heavy-Duty Aluminum Crank-Out Window: Built for All-Weather Comfort

When specifying windows for modern residential projects, balancing expansive views with reliable weatherproofing is always a critical challenge. Large fixed panels bring in natural light, but without effective ventilation and drainage, high-wind and heavy-rain seasons can cause issues.

The GWT-CRK100 Crank-Out Window is engineered specifically to solve these real-world building envelope challenges. Certified by Intertek and SAI GLOBAL, this system combines heavy-duty structural aluminum with a high-performance insulated glass unit to deliver year-round climate control.

Key Engineering Highlights

1. Robust 2.0mm Structural Profile

Unlike standard residential windows that use 1.4mm to 1.6mm extrusions, the GWT-CRK100 uses high-strength aluminum alloy with a solid 2.0mm profile wall thickness. This extra rigidity prevents frame deflection under heavy wind loads, ensuring smooth operation even on high-rise or coastal installations.

2. Integrated Sub Sill & Sub Head System

Water leakage around frame perimeters is one of the most common call-backs in window installation. The GWT-CRK100 comes pre-configured with a Sub Head and Sub Sill system. This design creates a secondary drainage channel to direct rainwater away from the building interior, significantly improving installation efficiency and water-tightness.

3. Advanced High-Performance Glazing (6mm + 12A + 6mm)

Thermal efficiency comes down to glass specification. The GWT-CRK100 features a double-glazed structure packed with energy-saving technology:

• Fully Tempered Glass: High impact resistance for safety and building code compliance.

• Energy-Efficient Low-E Coating: Reflects solar heat in the summer while trapping indoor warmth in the winter.

• Argon Gas Filling: Replaces ambient air between the glass panes to drastically reduce thermal transfer.

• Top Quality Warm Edge Spacers: Minimizes thermal bridging around panel edges, keeping condensation from forming during cold seasons.

4. Smooth Crank Operation & Customizable Hardware

The top-hinged / side-hinged crank-out mechanism allows precise air-flow control without taking up interior room space. Even during light rain, the outward-tilting sash acts as a canopy, allowing fresh air in while keeping moisture out. The hardware system can be customized to meet specific project aesthetics and security requirements.

Ideal Application Scenarios

• Bedrooms & Living Rooms: Pairs fixed picture windows with operable side crank-outs for unobstructed outdoor views and controlled airflow.

• Coastal & High-Wind Regions: The 2.0mm thick profile combined with multi-point locking mechanisms ensures long-term resistance to harsh weather.

• Modern Residential & Custom Builds: Sleek frame lines blend into contemporary interiors while meeting strict energy codes.
