Top tips to stay cool in a heatwave

Restless nights, blistering sunburn, a swarm of uninvited bugs in your living room… sounds familiar? With record breaking temperatures across the UK, we're all feeling the heat!

Although 38 degrees might be a blessing when abroad by the poolside, in Britain it feels almost oppressive. This is down to a variety of factors, from the fact that our houses are built to keep heat in, to our psychology: us Brits simply just aren't cut out for the heat.

It is, however, important to consider our windows too. With conflicting advice from experts, it can be hard to know how to utilise our windows best to maintain a cool temperature. That’s why we’ve pulled together some tips and tricks to keep you cool for the next few days!


Make sure your windows are double glazed

Never underestimate the importance of making sure your home has double glazed windows. As well as keeping the heat in, double glazed windows are also winners at keeping the heat out.

All modern windows are rated by the British Fenestration Council (BFC). The two main ratings to look at when considering how to keep cool in a heatwave are as follows:

  • G value- how much heat from the sun is transferred into your home
  • U value- indicates the insulating property of the material.

Double glazing helps to keep us cool in summer by limiting the amount of energy that can transfer from one side of the window to the other. This is even more effective in modern double glazed windows, such as the ones we install with argon gas.

Keep your windows shut

Keeping your windows closed may seem counter intuitive; however, if the air outside is hotter than the air in your home it may be better to keep them shut. This is especially applicable during the day, where it’s important to keep rooms that are facing the sun as shaded as possible.

At night time, although, it is generally accepted that cranking your windows open is beneficial to allow some of that cooler air in.

Use a reflective material on the outside of your windows

As a result of rising energy bills, many of us are hesitant to leave the fan running. But have you ever considered putting foil or another reflective material on the outside of your windows?

Recommended by the US government, this relatively unknown hack works by reflecting the sunlight back on itself to stop it from warming up your home.

However, if this is a bit ‘out there’ for you, luckily there are many other ways to help!

Close your curtains

Keeping your blinds and curtains closed when the sun is at its hottest is also a way to maintain a good temperature, with the curtains acting as a barrier between your home and the sun.

Furthermore, consider the colour of your curtains or blinds. Light coloured drapes are the best for keeping cool as they absorb less heat.


So, what are you waiting for? Utilise these tips and tricks to keep cool this summer, and head on over to get a quote today to make sure your windows are performing the best that they can!
