Stay Cool in Summer: An Energy-Efficient Window Coverings Guide

Summer comfort usually fails at glass. This isn’t opinion. Australian sources repeatedly describe windows as a major heat pathway, with up to 87% of heat gain in summer occurring through windows in some homes. 

If you want a cooler home without flogging the air con, the order of effectiveness is:

1) External shading (best impact)
External shading stops heat before it hits the glass. YourHome notes that shading windows can have a significant impact on summer comfort and energy costs and shading can be fixed or adjustable (including external blinds/louvres). 

Good external options:

  • Folding arm awnings for patios and big openings
  • External screens for west-facing glazing
  • External shutters for security + heat control

2) Screen/sunscreen roller blinds (strong day performance)
Screen fabrics reduce glare and solar load while keeping daylight usable. The openness factor controls the balance between view, glare control and privacy. 

3) Blockout blinds and lined curtains (strong peak heat + night performance)
Blockout helps when the sun is directly hammering a room or when privacy is needed at night. To increase performance, fit matters. Energy.gov.au recommends close-fitting lined coverings and pelmets. 

4) Plantation shutters (control + structure)
Shutters manage privacy, light and reduce glare. They also keep a consistent look from the street.

Melbourne-specific orientation tips

  • West-facing rooms: prioritise external shading + a sunscreen layer. Close before the sun hits the glass hard.
  • North-facing rooms: use adjustable solutions so winter sun can still be welcomed, but summer sun can be blocked. YourHome climate guidance explicitly recommends shading east and west glass in summer and using adjustable shading for variable solar access. 
  • Street-facing glazing: day privacy plus night privacy usually means double roller blinds or double curtains.

A quick “hot room” checklist

  • direct sun on the glass for hours
  • glare on screens
  • minimal external eaves/shading
  • large uninterrupted glazing
  • dark floors/furnishings absorbing heat

If you tick several, you’ll feel the benefit of external shading first.

Sustainable and Eco-Friendly Materials

Environmental consciousness is no longer optional—it's essential. Homeowners are increasingly choosing window treatments made from sustainable materials like organic cotton, bamboo, and recycled fabrics. These eco-friendly options don't compromise on style or quality, offering beautiful textures and durability while reducing environmental impact.

2

Smart Home Integration

Motorisation continues to dominate the market, but now with even more sophisticated features. Voice control, app integration, and automated schedules based on sunrise and sunset times are becoming standard expectations. The convenience of controlling your blinds from bed or while away from home is transforming how we interact with our living spaces.

3

Layered Window Treatments

The layered look is making a strong comeback. Combining sheer curtains with blockout options, or pairing blinds with decorative drapes, creates depth and versatility. This approach allows you to adjust light levels and privacy throughout the day while adding visual interest to your windows.

4

Bold Colors and Patterns

While neutrals remain popular, 2025 is seeing a surge in bold, statement-making window treatments. Rich jewel tones, dramatic patterns, and textured fabrics are being used to create focal points and express personality. Don't be afraid to make your windows a feature rather than just a functional element.

5

Minimalist Roller Blinds

Clean lines and simplicity continue to appeal to modern homeowners. Sleek roller blinds in neutral tones complement minimalist interiors while providing excellent functionality. The beauty lies in their simplicity—no fuss, just pure efficiency and style.

Making the Right Choice

When selecting window treatments, consider your lifestyle, aesthetic preferences, and functional needs. Each trend offers unique benefits, and the best choice depends on your specific situation. Our team at Luxe Interiors is here to help you navigate these options and find the perfect solution for your home.
