JL Windows supplies custom thermally broken casement windows in Melbourne for homes and building projects. A casement sash is hinged at the side and opens like a door, providing a generous opening and the ability to direct airflow when the configuration and conditions allow.
The JL Thermal system includes an insulating section between the internal and external aluminium profiles. It can be combined with compatible double glazing, Low E glass, privacy glass, hardware and flyscreens.
What Is a Casement Window?
A casement window uses side hinges and an outward- or inward-opening sash depending on the selected system. Opening direction, hardware, size, wind exposure and clearance must be reviewed for the project. The sash should not conflict with paths, screens, curtains, furniture or surrounding building elements.
Thermally Broken Aluminium Frame
Standard aluminium transfers heat readily. A thermal break reduces direct heat transfer through the frame by separating the internal and external profiles with an insulating section. This improves the frame component of the window, while the glass specification addresses the glazed area.

Double-Glazed Casement Windows
Double glazing uses two panes separated by a sealed cavity and can reduce heat transfer through the glass compared with basic single glazing. Combining a compatible double-glazed unit with a thermally broken frame addresses both the glass and frame components.
Actual performance also depends on seals, window size, opening function, installation and the wider building design. See our double-glazed windows Melbourne guide for glass options.
Casement Window Ventilation and Clearance
An open casement sash can capture and direct breezes, but it also projects from the frame. Check external paths, balconies, landscaping and cleaning access, as well as internal curtains and furniture for inward-opening systems. Any required opening restriction should be identified before ordering.
Casement Windows with Flyscreens
Compatible flyscreens can support ventilation while limiting insects. Screen type and position depend on the opening direction, handle and selected aluminium system. Confirm screens and any restrictors in the quotation.
Casement or Awning Windows?
Casement windows are hinged at the side, while awning windows are hinged at the top and open outward from the bottom. The appropriate style depends on ventilation, clearance, façade design, window proportions and weather exposure.

Replacement Casement Windows
Thermal casement windows can be considered for replacement projects where the opening, clearance and wall construction are suitable. Existing frames, reveals, flashing, access and surrounding finishes require assessment before manufacturing dimensions are confirmed.
