How Can I Keep My House Cool in Hot Weather?

In the UK, our homes are famously designed to keep us warm. But with global temperatures rising and heatwaves becoming more frequent, it’s time to shift our focus towards staying cool. Did you know that the UK’s average summer temperatures have increased by 1°C since the 1970s, and 2022 saw record-breaking heat, with temperatures soaring above 40°C for the first time ever?

According to recent data from the Met Office and UK Climate Projections, 2024 is shaping up to be another scorcher. Here’s how you can beat the heat and keep your home cool.

1. Close Curtains and Blinds During Peak Sunlight

Block out the sun’s rays with reflective blinds or blackout curtains. Studies show that drawing blinds or curtains can reduce heat gain by up to 30%.

Here’s what the Energy Saving Trust has to say:

“Close curtains and blinds, especially in rooms that face the sun. If you have shutters, keep them closed. Shading can reduce indoor temperatures by around 1-2°C and stop rooms from overheating.”

2. Close Windows During the Day and Open Them at Night

During the day, keep your windows closed to prevent hot air from entering your home. Open them at night when temperatures drop to let in the cool evening breeze and refresh your indoor air.

3. Switch to Energy-Efficient Lighting

Incandescent bulbs produce more heat than light. Replace them with energy-efficient LEDs to keep temperatures down.

4. Cool Your Body, Not Just Your Home

Sometimes it’s easier to cool yourself rather than your entire home. Drink plenty of water, wear lightweight clothing, and try cooling towels for an instant chill.

5. Embrace Cross Ventilation

Maximise airflow by opening windows on opposite sides of your house to create a breeze. Cross ventilation can significantly lower indoor temperatures.

6. Use Fans Wisely

Position fans strategically to circulate air or create an airflow directed at your seating areas. A bowl of ice in front of a fan can also provide a quick DIY air conditioner.

7. Install Energy-Efficient Windows

Traditional windows can act like greenhouses, trapping heat indoors. Modern energy-efficient windows with low U-values and optimized G-values can make a world of difference. They prevent excess solar heat from entering while keeping your indoor temperature stable and comfortable.

What Are U-values and G-values?

  • U-Value: Measures thermal insulation efficiency. The lower the U-value, the better the window keeps heat out during summer and retains warmth in winter.
  • G-Value (Solar Gain Coefficient): Indicates how much solar energy (heat) passes through a window. Lower G-values mean less heat enters your home, keeping it cooler.

7. Upgrade to High-Performance Windows by Gowercroft Joinery

Our award-winning energy-efficient windows are designed with advanced glazing technology to provide the perfect balance of low U-values and G-values:

  • Low U-values: Our windows minimize heat transfer, ensuring optimal thermal insulation.
  • Optimal G-values: Keep the summer heat at bay and maintain a cool indoor environment.
