Bedroom Too Bright or Too Cold? How Blockout Curtains Fix It
Blockout curtains darken a bedroom that gets light while someone sleeps, and slow the heat a room loses through its glass, when they are measured and fitted to close the gaps.
In a nursery, that means daytime naps and bright summer mornings. For a shift worker, it means sleeping through the middle of the day.
For light sleepers in street-facing rooms, the problem is street light and privacy at night. Whichever room it is, blockout curtains Sydney homes rely on come down to the right fabric, a curtain cut to the window and a fitting that closes the gaps.
Coated or Lined: How Blockout Curtains Work
There are two ways to make a curtain blockout, and they look and hang differently. A coated fabric has a coating bonded to its back, while a lined curtain has a separate blockout curtain lining sewn behind it.
Choose lined curtains for a heavier, fuller drape and a choice of face fabric. Choose a coated fabric for a lighter curtain and a single-layer S-fold. Triple weave curtains suit rooms that need less darkness.
Why Made to Measure Blockout Curtains Block More Light
A curtain measured to your window can be made wider and longer than the opening, so less light escapes at the sides and top. Most light in a blockout room comes in around the curtain, not through it.
Ready-made packs come in standard widths and drops and usually hang from a rod, leaving light gaps at the edges.
A made to measure curtain covers the opening with room to spare on a track fitted close to the ceiling. A measure includes fabric samples, track advice and installation.
Do Blockout Curtains Keep Heat In?
Yes. Closed blockout curtains slow the heat a room loses through its windows on cold nights and cut the heat it gains on sunny days. The Australian Government’s YourHome guide to glazing explains why: curtains that fit snugly with a pelmet trap still air against the glass. Heavy fabric or extra layers add insulation, which is why thermal curtains are often lined.
A pelmet is a panel over the curtain top that stops air moving behind it. For the warmest room, choose floor length curtains, close the top with a pelmet or ceiling fix, and draw them before the room cools. They can also help limit fading.
On west-facing glass in summer, thermal blockout curtains do less than shading outside the window, so look at our outdoor blinds and awnings.
