Perth summers are famous for endless blue skies, but with consecutive 40°C days, the indoor heat can quickly become uncomfortable. If your windows receive direct afternoon sun, your rooms can quickly become uncomfortable and harder to keep cool.
The right window coverings can help manage sunlight, reduce glare, and make your home more comfortable. Some blind fabrics are also designed to reduce solar heat entering through windows.
So, what are the best blinds for reducing heat in Perth homes?
In this guide, we look at sunscreen roller blinds, double roller blinds, plantation shutters, and Zebra blinds to help you choose the right option for your home or office.
What are Heat-Reflective Blinds?
When people search for blinds that reflect heat, they are usually looking for window coverings that can reduce the amount of sunlight and solar heat entering a room. These blinds generally feature:
- Reflective backings: Often white, silver, or light-toned backings that deflect UV rays and radiant heat.
- Dense weaves: Tightly woven fabrics that limit the amount of solar radiation penetrating the glass.
Good to know: While heat-reflective blinds substantially cut down direct solar heat gain, they are not a total substitute for structural wall insulation or air conditioning. Think of them as your first line of defence, easing the strain on your cooling system.
Do Blinds really help reduce heat?
Yes, the right window coverings can help reduce the impact of direct sunlight on a room.
This is especially useful for windows that receive strong morning or afternoon sun. By reducing direct sunlight and glare, blinds can help make the space feel more comfortable. The effectiveness depends on several factors:
- Fabric: Different fabrics allow different amounts of light and solar energy through.
- Colour: Some lighter or specially designed fabrics can help reflect more sunlight.
- Window direction: North- and west-facing windows can receive strong sunlight at different times of the day.
- Window size: Large windows can allow more sunlight into a room.
- Fit: A well-fitted blind can provide better coverage around the window.
Best Blinds for Hot Perth Summers
| Blind Style | Heat & Glare Control | Daytime Privacy | Best Suited For |
|---|---|---|---|
| Sunscreen Roller Blinds | High glare reduction, moderate heat block | Retains view outside | Living rooms, kitchens, home offices |
| Double Roller Blinds | Maximum (dual-layer control) | Complete day and night privacy | Bedrooms, media rooms, west-facing windows |
| Plantation Shutters | High insulation and airflow control | Fully adjustable | Street-facing windows, master suites |
| Zebra Blinds | Moderate heat block, versatile light control | Flexible transition | Modern living spaces, dining areas |
1. Sunscreen Roller Blinds
Sunscreen roller blinds are one of the most practical options for Perth homes that receive strong sunlight. They are designed to filter sunlight and reduce glare while still allowing you to maintain an outside view. This makes them particularly useful for living rooms, home offices, and windows that receive direct sun.
2. Double Roller Blinds
Double roller blinds give you two layers of control in one window.
Usually, one layer is a sunscreen blind and the other is a blockout blind. You can use the sunscreen layer during the day and the blockout layer when you need stronger privacy and light control. This makes them a flexible choice for Perth homes.
3. Plantation Shutters
Plantation shutters provide another way to control sunlight entering your home. The adjustable blades can be opened or closed depending on the amount of light you want. This gives you control over sunlight, glare, and privacy throughout the day. Plantation shutters can also provide a clean and lasting look that works well in both modern and traditional homes.
4. Zebra Blinds
Zebra blinds use alternating sheer and solid fabric sections. By adjusting the position of these sections, you can control how much light enters the room. They offer a modern look while giving you flexible control over light and privacy.
Blinds vs Curtains for Heat Control
Both options offer distinct advantages depending on your space:
- Blinds are sleek, compact, moisture-resistant, and easy to clean. They sit close to the window frame, making them practical for everyday high-traffic spaces, kitchens, and contemporary builds.
- Curtains—especially when fitted with heavy blockout thermal linings—trap air between the fabric and glass, creating a very strong insulating buffer.
The best approach? Layering. Pairing a sunscreen roller blind with floor-to-ceiling sheer or blockout curtains gives you flexible sun control during the day and maximum thermal insulation at night.
How to choose Blinds that help with heat
Consider these points when planning your window treatments:
- Check your aspect: West-facing windows need heavy blockout fabrics to survive Perth’s late-afternoon sun. East-facing rooms benefit from sunscreen fabrics to handle morning glare.
- Decide on your daytime view: If you love natural light and looking outside, choose a 3% to 5% open sunscreen fabric.
- Match the room’s function: Prioritise complete blockout options for bedrooms and nurseries to keep them dark and cool for sleep.
- Never compromise on fit: Off-the-shelf blinds leave wide side gaps where heat pours in. Custom, made-to-measure installation ensures snug coverage right to the edges of the reveal.

Frequently Asked Questions
What blinds are best for reducing heat?
Double roller blinds and blockout roller blinds with a white or reflective backing provide the strongest protection against solar heat gain.
Do sunscreen blinds reduce heat?
Yes. Sunscreen fabrics block up to 95% of harmful UV rays and significantly reduce radiant heat while allowing you to maintain an outside view during the day.
Are blockout blinds effective for hot weather?
Yes. High-quality blockout blinds stop direct sunlight from penetrating the glass, preventing the greenhouse effect inside your rooms.
What are the best blinds for west-facing windows?
Double roller blinds or heavy blockout blinds are ideal. They let you run sunscreen fabrics earlier in the day and switch to solid blockout when the harsh afternoon sun peaks.
Are blinds or curtains better for heat control?
Both work well. Blinds excel at deflecting direct light and glare close to the glass, while lined curtains create a thick dead-air insulation layer. Combining both yields the highest thermal performance.
