9 Ways Blinds and Curtains Can Keep Your Home Cool in a Heatwave

As summer heatwaves become more common, keeping your home cool can be a real challenge, especially in properties that aren’t designed to cope with extreme temperatures. While fans and open windows offer temporary relief, your window dressings could actually be one of your strongest defences against the heat.

At Cambridge Interiors, we believe beautiful design should also be functional. Here are nine ways the right blinds and curtains can help you stay cool and comfortable when the temperature rises:

  • Block Out Direct Sunlight

One of the most effective ways to stop heat from building up indoors is to block direct sunlight. Opt for thermal or blackout-lined curtains and reflective blinds to reduce solar gain and keep rooms noticeably cooler.

  • Use Light-Coloured Fabrics

Lighter shades naturally reflect sunlight, so choosing pale, breathable fabrics can help reduce heat absorption. White or neutral blinds and curtains are both stylish and practical in hot weather.

  • Layer Curtains with Blinds

Combining sheer blinds with thicker curtains gives you the flexibility to adjust light levels and manage indoor temperatures more precisely throughout the day.

  • Close Curtains During Peak Sun Hours

Keeping your blinds or curtains closed from late morning to mid-afternoon, especially in south-facing rooms, can dramatically reduce indoor heat build-up.

  • Install Thermal or Solar Reflective Blinds

Thermal blinds and solar shades are designed to reflect heat while still letting in light. Perfect for those who want a bright space without the added warmth.

  • Opt for Motorised Blinds

With automated blinds, you can schedule them to close during the hottest parts of the day, even when you’re not home. Smart control ensures a cooler return in the evening.

  • Choose Breathable Natural Fabrics

Curtains made from linen or cotton not only look relaxed and elegant but also promote air circulation, helping the room breathe on stifling days.

  • Use Day-to-Night Combinations

Daylight blinds can filter strong sunlight during the day, while blackout curtains provide full protection in the afternoon and evening when the sun is strongest.

  • Custom Fit for Maximum Efficiency

Gaps around window dressings let heat in. Choosing made-to-measure curtains and blinds ensures a snug fit, reducing air leaks and increasing your home’s cooling potential.
