Blockout roller blind pulled down across a bedroom window

Blockout blinds in Brisbane for cooler, darker rooms.

Where the light gets in, and how to stop it

Blockout fabric does exactly what the name suggests, but a blind made from it can still leave a room disappointingly light. The fabric isn't usually the problem. Light comes in around the edges, through the gap between the blind and the reveal, or over the top of the roll. At Studio Curtains & Blinds, we fit blockout blinds in Brisbane bedrooms, nurseries and media rooms with that in mind, mounting outside the reveal or adding side channels where genuine darkness is the point. The dense fabric also blocks radiant heat, which makes a noticeable difference on a west-facing window through summer. For a softer look with the same result, blockout curtains are worth comparing.

Blockout blind lowered to keep afternoon sun out of a room

Getting a room genuinely dark

Four details separate a blind that darkens a room from one that merely dims it.

  1. 01

    Mounting position.Fixing outside the reveal, above and wider than the frame, removes most of the perimeter light leak.

  2. 02

    Side channels.Aluminium tracks down each side capture the fabric edge, which is the most effective option for a media room.

  3. 03

    Pelmet or fascia.Enclosing the top of the roll stops light escaping over the tube and down the face of the blind.

  4. 04

    Fabric backing.A white or reflective backing bounces heat away from the glass as well as stopping light.

FAQs

Standard mounting leaves a small clearance on each side so the fabric can travel freely, and light enters through those gaps. Outside mounting, side channels or a pelmet each close off a different part of the leak.

An opaque fabric stops radiant heat passing through the glass, so a closed blind slows how quickly the room warms. A light-coloured backing improves this further by reflecting heat back outwards.

Yes, blockout fabrics come in a wide colour range, with the light-stopping layer built into or coated onto the back. The room-facing side can be chosen independently of that backing.
