How to keep your loft conversion cool in the heat

We're about to have our first proper heatwave of the year, but how do you ensure your loft conversion can handle the heat?

Warm air rises and this could result in your loft being a few degrees hotter than the rest of the house, so you need to take this into consideration when designing your loft space.

Below are some great tips on how to keep your loft cool:


The easiest way to keep a room cool is to ensure it's well ventilated and the type of windows you have installed will make a big difference.

We recommend smart windows such as the Velux Integra windows. Once opened, they can be set to close automatically after 15 minutes, or sooner if it starts to rain. They can also be closed with a click of a button when you leave the house.

Have ventilation flaps installed too and they can be set to open regularly for 15 minutes during the day whilst your windows remain closed, maintaining a comfortable climate. Passive slack ventilation can also be used to add vents throughout the room, drawing cool air down and forcing hot air out.

Having a Juliet balcony is another great way of increasing ventilation. As well as creating a focal feature to the room, there's the added benefit of increasing natural light, airflow, and creating a feeling of increased space.

Control Direct Sunlight

If you want your loft space to feel light and airy it means letting in as much natural light as possible, which our skilled architects can help you with. However, more sunlight can also mean that the space gets super-heated in summer.

So to maintain a comfortable indoor temperature, have Velux sun screening products installed along with your windows and these can be set to keep heat out during the hottest hours of the day.  

Solar-Powered Air Conditioning

Admittedly, air conditioning is not usually environmentally-friendly, but there are a number of solar-powered systems on the market that harness the very thing that causes your loft to heat up in the first place.

Installing a solar powered air conditioner allows you to cool down the room without drastically increasing your carbon footprint. At the same, time you save money on energy bills as you're generating your own power to run the unit.


As strange as it may seem, good insulation is quite important when it comes to controlling the climate in your home. Using a high-performance insulating board will lock heat in during the winter months but will also prevent the build up of heat during hot summer days. Effective insulation can mean you save on winter fuel bills and have a cooler space during the summer months. So before you start planning your loft conversion, talk to our team and we'll design you a loft space that keeps you cool in summer and warm in winter.
