Blockout vs sunscreen blinds.

The one sentence version.

Sunscreen keeps your view and kills glare during the day. Blockout kills all light and gives privacy day and night. If a room needs both, you need two fabrics, which is what a double roller is for.

Side by side.

The night-time trap.

This one catches people out constantly and it is worth being blunt about. During the day, sunscreen fabric reads as opaque from the footpath because outside is the brighter side, so it feels completely private. After dark that flips. Your room is now the bright side, and anyone standing on the street can see shapes, movement and the shape of the room through the weave. On a small estate block in Officer where the front window is eight metres from the footpath, that is a real problem. A sunscreen blind gives you daytime privacy only. Any room where you want privacy at night needs blockout, either on its own or as the second layer of a double roller.

The darkness trap.

The mirror-image mistake is assuming a blockout blind gives a black room. The fabric blocks 100 percent of light passing through it. The installation does not. Light comes around both edges, over the top of the roll, and under the bottom rail, so a bedroom in blockout is dim rather than dark at 6am in December. If real darkness matters, for a shift worker, a nursery or anyone who struggles to sleep in summer, ask for side channels, and ideally a pelmet over the top. Channels add roughly $60 to $140 per window and they are the difference between a dark room and a properly dark room. This is worth deciding at the measure, because retro-fitting channels later means new brackets and often a new blind.

Room by room, for a Pakenham house.

• Main bedroom and children's bedrooms: blockout, with channels if anyone sleeps late or during the day. Cordless where a child can reach, see child-safe blinds.
• Nursery: blockout with channels, cordless, no exceptions.
• Open-plan living and dining: double roller. Sunscreen at 3 to 5 percent openness for the day, blockout behind it for evenings and for the worst of a 38 degree afternoon.
• Kitchen: sunscreen or a wipeable light-filter. You want the light and you rarely need privacy at the sink window.
• Study or home office: sunscreen, because screen glare is the whole problem and darkness is not the answer.
• Bathroom and ensuite: blockout or a translucent light-filter, depending on how overlooked the window is.
• Media room: blockout with channels, every time.

Why the double roller is the default here.

A double roller carries both fabrics on a single bracket at the same window. One blind position for the day, another for the night, no compromise on either. In the Cardinia growth corridor, where living rooms have wide west-facing glass and small front setbacks, it solves the two problems that otherwise force an unhappy choice. Cost is roughly $260 to $600 per window in 2026, which is close to double the fabric of a single blind plus a small premium for the dual bracket. That is cheaper than two separate blinds and far cheaper than replacing a single blind in a year when you realise it only does half the job. The wider heat discussion, including where honeycomb beats both fabrics, is in best blinds for Pakenham heat.

What about light-filter fabric?

There is a third category people forget. Light-filter (or translucent) fabric is solid rather than open weave, so you cannot see through it in either direction, but it passes a soft diffused light. It gives full daytime and night-time privacy while keeping a room bright. It suits bathrooms, laundries, a front bedroom that faces the street, and any window where privacy matters more than the view. It is the right answer more often than people expect and it costs about the same as blockout.

How to decide at your own window.

Stand in the room at the hour you use it most and ask two questions: do I need to see out, and can anyone see in when the lights are on. If you need the view, you need sunscreen. If you need night privacy, you need blockout or light-filter. If the answer to both is yes, you need a double. We bring the fabric books to the measure so you can hold each sample against your own glass and see the difference rather than guess from a photograph. Pricing across all fabric types is on the cost guide, and if you are furnishing a new estate home the timing advice is in blinds for new builds.
