Harbour Alloy is a hybrid window system that combines the insulation properties of uPVC with the strength, finish stability, and durability of an aluminum exterior.
It is designed for architectural projects where long-term exposure, visual consistency, and material performance are critical considerations.
Harbour Alloy is often selected when standard uPVC finishes are not sufficient for the design intent or environmental exposure.
Harbour Alloy uses a uPVC structural frame paired with an extruded aluminum exterior cladding.
This hybrid approach allows the system to balance energy efficiency with architectural durability.
The aluminum exterior provides a clean, modern appearance and is well suited to contemporary architectural styles.
Finish options are selected to maintain color stability and resistance to corrosion, particularly in coastal conditions.
Harbour Alloy bridges the gap between premium uPVC systems and full European-style performance windows.
For projects that require the highest levels of airtightness, sound control, and system performance, the Fjord Series may be considered.
Harbour Alloy windows are manufactured locally and supplied through Thermoproof’s established process, with installation coordinated directly or through authorized partners depending on project location.
