When it comes to beating the Aussie heat, you might first think of cranking the aircon or grabbing a fan. But what if your secret weapon is already hanging in your window? Blockout blinds are often praised for their ability to darken a room, but do blockout blinds reduce heat too? Spoiler: yes, they can. And we’re about to uncover how.
Exploring the Role of Blockout Blinds in Temperature Control
Here’s the thing: many people assume that blockout blinds are just for sleeping in or binge-watching Netflix at noon without a glare. But their powers go beyond darkness. One of their underrated abilities is helping control indoor temperatures.
That said, they’re not magical shields that turn your home into an icebox. Instead, they act as a barrier, blocking out sunlight and insulating your windows, which just so happen to be one of the biggest culprits when it comes to unwanted heat.
So, while blockout blinds won’t cool a room like air conditioning, they do play a role in preventing it from heating up in the first place.
How Blockout Blinds Work to Reduce Heat: Mechanisms Behind Heat Reduction
Sunlight streaming through glass is beautiful, but it’s also the main reason your home starts to feel like a greenhouse. Blockout blinds work by intercepting solar radiation before it can transform into trapped heat.
Think of them as the sunscreen for your house—the less sun gets in, the less heat builds up.
Material Composition – The Impact of Fabric Thickness and Lining
If you’re wondering what are the best blockout blinds, the real MVP here is the material. Blockout blinds typically feature multiple layers: a decorative front, a dense core, and a specialised backing designed to deflect sunlight and trap heat.
Thicker, tightly woven fabrics do a better job at this. Some blinds even include a thermal lining, which boosts insulation and further blocks heat transfer between your window and the rest of the room.
In short: the thicker the fabric and the more layers it has, the better it will be at keeping the heat out and the cool in.
Colour Considerations – Does the Colour of Blockout Blinds Affect Heat Reduction?
Yes, colour matters. Light-coloured blinds tend to reflect sunlight, while darker shades absorb it. This might seem like a win for team white, but it depends on where the blinds sit.
If your blinds are installed on the interior of the window, dark colours can still absorb heat and radiate it into the room. If you’re really focused on heat reduction, opt for light-coloured blockout blinds with thermal backings. They bounce the sun away without compromising darkness or insulation.
Additional Benefits of Blockout Blinds – Beyond Heat Reduction
If heat control was the only thing blockout blinds did, that would already be pretty impressive. But they’re overachievers. Let’s talk about the other perks that come with a good set of blockouts.
Light Control – Achieving Complete Darkness for Better Sleep
Whether you’re a shift worker, a nap enthusiast, or a parent of a toddler who refuses to sleep past sunrise, total darkness is a game changer. Blockout blinds shut out even the most stubborn light sources—streetlights, early dawns, neighbour’s fairy lights—you name it.
Your brain’s sleep-wake cycle thrives in the dark. Better sleep equals better mornings, and who doesn’t want that?
Energy Efficiency – Reducing Energy Costs Through Insulation
Here’s where the savings kick in. By insulating your windows, blockout blinds reduce the need for artificial cooling in summer—and heating in winter. That means lower energy bills, reduced environmental impact, and less dependence on air conditioners.
It’s a quiet kind of efficiency that adds up over time, and it’s just another reason blockout blinds are a savvy home investment.
How to Install Blockout Blinds – Step-by-Step Installation Guide

Measuring Your Windows – Ensuring a Perfect Fit
First things first: measure. Twice. Maybe three times.
You’ll want to decide between inside mount (fitted within the window frame) or outside mount (covering the frame completely). Each has its perks, but for optimal light and heat blocking, outside mounts usually win.
Measure the width and drop of each window accurately, noting if any trims or handles might get in the way. Custom-fit blinds look neater, work better, and avoid that dreaded gap of sunlight streaming through the sides.
Installation Process – DIY Installation Tips
Once you’ve got the right size, the rest is smooth sailing. Most blockout blinds come with brackets, screws, and clear instructions. You’ll need a drill, level, tape measure, and possibly a helper to hold things in place.
-
Mark the bracket positions.
-
Drill pilot holes and secure the brackets.
-
Slot in the headrail or roller mechanism.
-
Test the function—raise, lower, and roll with satisfaction.
Pro tip: if you’re mounting above the window frame, leave enough space so the blind fully clears the glass when rolled up.
Choosing the Best Blockout Blinds – Factors to Consider
Choosing the right blockout blinds isn’t just about practicality; it’s also about personality. Your windows are focal points, so make sure your blinds match the vibe.
Material Options – Comparing Different Fabrics
There’s a wide world of materials out there, from cotton/polyester blends to PVC-coated fabrics and triple-layer thermal blockouts.
-
Polyester is durable, affordable, and resists wrinkles.
-
Thermal blinds offer layered insulation, ideal for extreme climates.
-
PVC-coated fabrics are easy to clean and great for kitchens or bathrooms.
Choose based on the room’s purpose, sun exposure, and how much insulation you need.
Style and Design – Matching Blinds to Your Home Décor
Blockout blinds don’t have to be boring. They now come in sleek neutrals, bold patterns, textured weaves, and minimalist finishes.
Choose a style that complements your furniture, wall colour, and mood. Want a clean, modern look? Go for crisp whites or matte greys. Prefer a natural, earthy tone? Soft taupes and linen-style textures work wonders.
