Should you open your loft hatch in hot weather? How to keep house cool in heatwave

News

This week the UK has been plunged into an intense heatwave – and temperatures are expected to reach a record-breaking 41C.

The Met Office has issued an extreme heat warning and many places across the country have already experienced 37C temperatures, with roads melting and train tracks buckling.

UK homes just aren’t built for this kind of weather, making the heatwave even more unbearable for many of us.

Without any air conditioning, it isn’t long before our homes skyrocket in temperature, but thankfully there are a few hacks to help you get through it.

One of them includes your loft, which may provide a simple way to cool down your entire home.

Should you open your loft hatch in hot weather?

Yes, opening your loft hatch can be a nifty solution to reducing the temperature in your home.

This is because hot air rises and an entrance for the heat to escape will lower the temperature in the rest of the home.

Victoria Arrington, a spokesperson for Energy Helpline, told This Is Money: “If you have a loft window, opening it up will let out warm air, and that will likely produce a cooling effect – especially if you open some additional windows in your home to keep the air flowing.”

However a spokesperson for Green Age adds that the type of loft you have makes all the difference, saying: “Opening the loft hatch might seem like a quick fix to your hot master bedroom, but is only really an option if your loft is insulated between the rafters.

“If your loft is insulated at joist level, then you may find that opening the hatch only causes the even hotter trapped air to circulate.”

However, if there is a cool airflow through your home, it should be achieved through the use of a fan.

While opening your windows during normal hot days can help, when the temperature reaches the levels we are experiencing now, the advice actually changes.

It isn’t advised to keep your windows open during the heatwave as it can let in more hot air that a breeze would help mitigate.

Other hacks to cool down your home

Alongside keeping your windows closed, it is also advised you close your blinds or curtains to keep out the sun’s rays.

These beams of light directly heat up your home, so it isn’t advised to keep your blinds open.

Also, alongside the use of a fan, you should place ice in front of it as it can amplify the cool air.

As the ice melts, cold air will be blown around the house, providing some relief.
