Thermally Broken Double Glazed Aluminum Windows in Perth

For modern builders, balancing style, performance, and energy efficiency can be challenging—especially in Western Australia's warm climate. When Mansour Mohseni, a Perth-based builder, set out to construct a sleek and sustainable residence, he needed window solutions that would deliver comfort, efficiency, and long-term durability. After thorough comparison among multiple manufacturers, Mansour chose ROPO for its proven quality, engineering expertise, and reliable customer service.

📍 Location: Perth, Western Australia

🏠 Building Type: Residential

👷 Client Type: Builder

🎯 Project Goal: Create a modern, energy-efficient home that complies with Australian standards and achieves superior thermal insulation.

In 2022, Mansour reached out to ROPO for consultation. After discussing his vision for a contemporary, high-performance home, ROPO's team recommended thermally broken double-glazed aluminium windows and doors with Low-E glass to achieve exceptional energy savings and indoor comfort.

ROPO supplied a complete thermally improved window and door system, including:

Aluminium Fixed Windows

Aluminium Awning Windows

Aluminium Sliding Doors

Aluminium Hinge Doors

Each unit was engineered to meet AS2047, AS1288, and WERS certifications for safety, performance, and energy efficiency.

These products were made with high-quality 115 mm commercial-grade aluminium profiles:

Material: 6063-T5 aluminium alloy

Surface Finish: Interpon D1010 powder-coated Monument (German brand, 10-year warranty)

Powder Thickness: 60 microns

Frame Thickness: 1.6 mm for windows / 3.0 mm for doors

The thermal break separates inner and outer aluminium profiles using high-performance polyamide, reducing frame U-values from ~2.0 to ~1.0 Btu/hr·ft²·°F

This technology is key for meeting Passive House-level energy performance targets.

Color: Monument (Colorbond® range)

Powder: Interpon – 10-year warranty

'We compared several aluminium window manufacturers, and ROPO stood out for their product quality and professionalism. The thermally broken system performs exceptionally well, keeping indoor temperatures stable even on Perth's hottest days. Their communication and technical support made the process seamless.'

Traditional aluminium windows often struggle with heat transfer, which can increase energy costs. ROPO's thermally broken aluminium frames significantly reduce heat conduction, offering:

✅ Better insulation & lower energy bills

✅ Enhanced comfort in all seasons

✅ Compliance with Australia's toughest energy standards

✅ A clean, modern look suited for contemporary architecture
