Series T3 120 Thermal Break Casement Window with Screen
-
The Series T3 120 Thermal Break Casement Window with Screen combines a robust thermal break aluminum frame with precision European hardware to deliver a high-performing casement window suitable for residential and commercial projects. It can be specified as a standalone casement, a fixed unit, or a combination.
Key Features
- 2.0 thickness design provides a sense of security, fearless of typhoon weather
- Large beveled edge line and narrow edge design offer a broad and transparent view
- 27A large hollow glass reduces noise and maintains quiet
- Hidden drainage structure effectively prevents the risk of rainwater backflow
- Hollow glass filled with argon gas significantly improves the overall thermal insulation of the window

Frequently Asked Questions
What is a thermal break and why does it matter?
The thermal break is an insulating polymer strut between the interior and exterior aluminum surfaces of the frame. It prevents cold or heat from conducting straight through the metal, dramatically improving U-value and preventing interior condensation.
How is the hardware quality?
We use branded European hardware (Roto, GU, or equivalent) for hinges and locking systems on all casement units. Hardware is corrosion-resistant grade suitable for coastal environments on request.
What is the U-value of this window?
With standard double glazing and thermal break profile, U-value is typically 1.4-1.8 W/(m²·K). Triple glazing lowers it to 0.8-1.1 W/(m²·K). Exact figures depend on frame series and glazing choice — request the spec sheet for your configuration.
Can the window be reversed (inswing/outswing)?
Most casement windows are configured inswing by default. Outswing is available on request. Fixed units have no opening mechanism. Confirm orientation at quote stage.
Do you supply matching fixed and operable units together?
Yes. Combination frames with fixed and casement sections in a single unit are a standard configuration. This creates a large glazed area with strategic ventilation.
