Solar Heat Gain & External Fabrics: Choosing the Right Option for Brisbane Homes

External blinds are one of the most effective ways to reduce heat in your home — but choosing the right fabric makes all the difference.

What Is Solar Heat Gain?

Solar heat gain refers to the amount of heat that enters your home through windows.

In Brisbane, this can significantly increase indoor temperatures and energy use.

External blinds help stop heat before it reaches the glass, making them far more effective than internal coverings alone.

Screen Fabrics: 1% vs 5%

Screen fabrics are commonly rated by openness factor.

1% Openness

• Blocks more heat and glare

• Offers greater privacy

• Reduces visibility through the fabric

Best for:

• Western-facing windows

• High sun exposure areas

5% Openness

• Allows more natural light

• Maintains better outward visibility

• Still reduces heat effectively

Best for:

• Areas where view is important

• General living spaces

Solution-Dyed Acrylic Fabrics

Acrylic fabrics are another premium option.

They offer:

• High durability

• Excellent UV resistance

• Strong colour retention

• A softer, more traditional awning look

These are ideal for:

• Folding arm awnings

• Premium outdoor applications

What Should You Choose?

The right fabric depends on:

• Sun exposure

• Privacy requirements

• Desired level of visibility

In our experience, Brisbane homeowners often choose a balance — using 1% fabrics for high-exposure areas and 5% where visibility is preferred.

Reduce Heat, Improve Comfort
