Should you tilt your blinds up or down to keep your room cooler? We reveal all

When the heat is on, I try all sorts of hacks to keep cool during a heatwave, from trying the ‘caveman method’ (it’s not as bizarre as it sounds) to beating the heat using wet laundry. But there’s one way that you can keep cool that’s far simpler than either of these methods, and it has to do with the direction you tilt your blinds.

Does it help to tilt the blinds up toward the window, or down toward the room? When it comes to keeping a room cooler, it’s best to tilt your blinds up — here’s why.

Tilt your blinds upwards to stay cool

Your blinds are tilted upwards when the top of each slate is angled toward the window.

This prevents the sun from shining directly inside and is the best position to place your slats in the summer. When the slats are angled in this manner, sunlight and heat are reflected back outside. So, if you have a south-facing room, you’ll notice a difference if you positioned your blinds in this way.

Within a YouTube video, Penny Rafferty Realty explains how the direction of the slats on your blinds influences the temperature of your room.

Privacy

Apart from reducing the amount of sunlight and heat entering your room, positioning your blinds in this position also provides added privacy. Upturned blinds make it impossible for anyone outside to take a peek inside your home. I have shutters in my bedroom, so I always make sure my blinds are set on ‘privacy mode’.

Soft light

When light is aimed toward the ceiling, it also creates a soft ambience, reducing any harsh glare. This effect is perfect for rooms where you choose to relax, such as bedrooms and sitting rooms.

Protect your furnishings

By shielding your room from direct sunlight, you are also protecting your furnishing, as the sun’s Ultraviolet rays fade textiles and carpets. If you tilt your blinds up during the day when the sun is at its strongest, you’ll reduce the effect of sun damage.

These authentic hardwood slated blinds will add a touch of elegance to any room. I prefer the painted white option, but they are also available in cream, oak, pine, hickory and mahogany stains. This option is for a blind measuring 24 (W) x 36 (H), but other sizes are available.

Tilt your blinds down to absorb the heat

Your blinds are turned down when the top of each slat tilts towards the room. When they are in this position your room will be become warmer and light and heat are being encouraged to come in.

More sunlight

When your blinds are tilted downwards, more sunlight is directed to the lower half of the room, and when closed completely, some light will still come through, adding a soft glow to what would otherwise be a darkened room.

More heat

While you might prefer the reverse angle in the summer, having your shutters angled downwards in the winter can help to keep your room warmer, offering the warmth of free solar heat. And, for the full benefit of the sun’s rays, open your blinds completely.
