I’m Wondering Why I Waited So Long to Try This 'Heat Reflective' Window Film — It's Cheap and Will Stop My House From Boiling Over in the Heatwave
For less than £7, this heat reflecting window film is a no-brainer solution to keeping the heat out during this sweltering summer


This really feels like one of the hottest summers we've ever had — having to wear as little clothing as possible without raising eyebrows, while fighting an assault of dosey wasps that are as exhausted with the heat as we are — it can be hard to actually cool ourselves down.
A lot of the time, it feels even hotter than the weather app reads, as our homes in the UK are just not built to deal with the heat in the way that other countries are. And with summers like this likely to be the new norm, we must find whatever solutions we can to make the heat more bearable.
That's why when I stumbled across this Heat Reflective Window Film on Amazon for just £6.79 in the Amazon Prime Day sale, I was more than a little overjoyed. The one-way mirror film keeps the heat out during the day, with advanced UV-blocking to boot.
It's easy to remove, making it one of the best window treatments to keep a house cool this summer. Of course, the 'mirrored window' look is great for privacy during the day, but understandably not for everyone; however, for the price, I would use it just for the summer months to beat the heat, as it's super easy to remove, after all.
Prime Day ends tonight, so if you want to take advantage of the deal, don't hang about for long.
- Size: 44.5x200 cm (also available in a range of larger sizes)
