It’s snowing inside. At least that’s what it feels like.

It’s the middle of the night, toes numb, face stinging. Buried under two blankets with Nan’s hand-knitted slippers, none of it helping. The heat pump hums, but the room feels like a tent pitched on a glacier.

You turn to the culprit: wafer-thin curtains, limp as tissue, barely clinging to the window. Not blocking the cold, but practically welcoming it in. You sigh. Your power bill flashes in your mind. Then your toes. Then life without your toes. Frostbite feels inevitable.

If this feels all too familiar, we’re here to remind you that curtains and blinds are one of the easiest, most effective ways to winter-proof your home. And this ultimate guide will show you exactly how to do it, so you can be as snug as a bug in a rug this cosy season. But first, let’s look at why your windows are the real problem…

Why Windows Are Your Home’s Weak Spots

Newsflash! Up to 40% of a room's heat escapes through windows. That’s more than walls or ceilings. Glass is a poor insulator, especially in older or single-glazed homes, meaning even the most committed heat pump, putting in a double shift, can’t outwork the exposed glass. 

Thankfully, a long time ago, humanity discovered that layering fabric over windows creates a thermal barrier that slows heat loss, blocks draughts, and keeps your heating costs down. And the best part? It’s not as complicated (or expensive) as you might think...

How Curtains and Blinds Actually Keep the Heat In

Curtains and blinds aren’t just for looks. When properly chosen and installed, they work hard to keep the warmth in and the cold out. Here’s how:

• Trap a layer of air: The space between your curtains or blinds and the window acts as a buffer zone, slowing the transfer of heat and keeping warmth indoors.

• Reflect radiant heat: Fabrics with thermal or blockout coatings bounce warmth back into the room, helping your heat pump work more efficiently.

• Slow heat loss through density: Thicker or multi-layered options like triple-weave and blockout curtains resist temperature changes and absorb sound.

• Block draughts with full coverage: Floor-length curtains that sit wider than the frame seal off gaps where cold air can sneak in.

• Minimise condensation risk: By keeping the window’s interior surface warmer, good coverings prevent moisture build-up that can lead to mould.

• Promote healthier air: Mould-resistant, breathable materials are ideal for damp or poorly ventilated rooms during winter.

Together, these tactics turn ordinary windows into high-performing insulators. A bona fide winter window makeover, minus the sledgehammer. But, which curtain types actually tick these boxes? Let’s break it down…

What Makes Curtain Studio’sHoneycomb Blinds So Good?

• Built-in thermal barrier: Their signature hexagonal cells create air pockets that act like invisible insulation, trapping warmth in, keeping cold out, and helping maintain stable indoor temperatures 24/7. It’s the double glazing effect, minus the hefty invoice.

• Condensation control like a pro: By maintaining a warmer internal surface on your windows, these blinds help cut down condensation, which means less mould, less mildew, and fewer soggy sills this winter.

• Gap-free insulation: Curtain Studio’s honeycomb blinds are designed to fit snugly with minimal gaps around the edges, creating a seal that locks in comfort and keeps energy bills in check.

• Sleek, strong and built to last: Their low-profile look suits even the most design-conscious homes, while the bonded fabric construction delivers quiet strength and long-term durability, without the bulk.

How to Install Curtains and Blinds So They Keep the Cold Out

Even the best thermal fabrics won’t perform if they’re poorly installed. For real insulation, precision matters. So for toes-out warmth this winter, follow these tips from our team:

• Go floor-length to trap warm air and stop cold draughts sneaking in below.

• Extend past the window frame on all sides to block edge leaks and seal the space.

• Use double tracking to layer sheers with linings, combining softness with insulation.

• Line your curtains with attachable blockouts or triple-weaves for an instant upgrade.

• Position linings on a separate track behind sheers for extra privacy and warmth.

• Fit tightly to the wall or frame, think of it like sealing a chillybin: every gap counts.

• Let in the sun during the day, close before dusk to lock in natural heat.

These small adjustments will deliver serious improvements, especially in older, single-glazed homes. Once you’ve nailed the install, there’s one final piece of the puzzle that everyone conveniently  forgets: cleaning. Learn how below…  

How to Maintain and Clean Your Curtains and Blinds

Regular care extends the life and performance of your window furnishings. Here’s how to keep your magnificent cold-blocking friends working their best for winters to come:

• Vacuum weekly: Use a soft brush attachment to remove dust and allergens, especially in pleats and along hems.

• Steam for freshness: A handheld steamer can remove wrinkles and kill dust mites without taking curtains down.

• Avoid direct sunlight: Rotate curtains periodically to prevent uneven fading from UV exposure.

• Professional cleaning: For delicate fabrics or deep cleaning, we recommend professional services to avoid damage.

By treating them right, your curtains and blinds will keep doing what they do best: making winter feel less like survival and more like a snug season.
