East-Facing Bedrooms Have A Deadline
In December the sun is up over the water before five, and it arrives at an angle that walks straight into an east-facing bedroom. That is the single most common reason someone on the Gold Coast rings us about blockout curtains, and it is also the reason the fabric spec matters less than the fit: at that angle the light comes in along the top edge and down the sides long before it comes through the cloth.
The other half of the problem is heat. A blockout curtain closed against a western wall in February is doing what it can, but by then the sun is already through the glass. Shading the outside of the window is what actually keeps the room cool — the Australian Government's Your Home guide to shading is blunt about it, and so are we. If that is your real problem, an outdoor blind or an awning will beat any curtain we could sell you.
So we ask which way the room faces before we talk fabric. It changes the answer more than the colour chart does.
