Double hung windows remain a popular choice in Australian homes due to their timeless design, flexible ventilation options and increasing alignment with modern energy efficiency standards. As Australia’s renovation and building industries continue to evolve under new environmental and design expectations, double hung windows have been adapted to meet these contemporary needs.
What are double hung windows?
Double hung windows feature two operable sashes that slide vertically within the frame. This design allows both the top and bottom sections to open, promoting effective airflow and easy cleaning. They suit a wide range of home styles, from traditional Federation homes to sleek modern builds.
Why choose double hung windows?
- Improved Ventilation: The dual-opening sashes offer greater control over airflow, helping regulate indoor temperature naturally.
- Energy Efficiency: With rising energy costs and stricter energy ratings (such as the 7-Star NatHERS standard), today’s double hung windows are often fitted with double or triple glazing, low-emissivity (Low-E) glass, and argon gas fills to maximise thermal insulation.
- Contemporary Materials: Modern frames are available in thermally broken aluminium, uPVC, composite materials and sustainably sourced timber. These options minimise maintenance while enhancing energy performance.
- Security and Safety: Enhanced locking mechanisms, toughened or laminated glass, and child-safety features make these windows suitable for families and upper-storey installations.
- Aesthetic Flexibility: Slimline aluminium frames cater to minimalist tastes, while timber options suit heritage restorations, ensuring visual continuity across styles.
Trends driving window design in 2025
- Sustainability: Builders and renovators are prioritising sustainable materials and energy efficiency. Upgrading to energy-efficient double hung windows is a key step in sustainable refurbishment.
- Smart integration: Homeowners are adopting smart window technologies including automated blinds, sensors and remote-controlled openings.
- Triple glazing: Particularly in cooler climates, triple-glazed windows are becoming a preferred option for superior insulation and acoustic control.
- Compliance with updated building codes: New standards mandate improved thermal performance, pushing demand for high-performance glazing and insulated frames.
Choosing the right double hung window
When selecting double hung windows, consider:
- Glazing type: Choose double or triple glazing with Low-E coatings and inert gas fills for optimal performance.
- Frame material: Aluminium with thermal breaks offers durability; timber adds natural warmth; uPVC delivers great insulation at an affordable price.
- Climate suitability: Consider your local climate zone and orientation to determine the best window specifications.
- Security needs: Opt for products that meet or exceed Australian safety and security standards.
Double hung windows are more than just a traditional choice, they represent a smart investment in comfort, efficiency and home value. As Australia moves toward greener, more energy-conscious living, these windows have adapted through innovative materials, better insulation, and smart technologies. Whether you’re renovating a period home or building new, double hung windows continue to offer practical benefits with modern-day performance.
