Hip to Gable L-shaped Loft Extension in Brixton ext alt 2 - 10 Considerations when planning a loft conversion - ways to keep your loft conversion cool in summer

A loft conversion is an awesome way to add more useable space to your home and create an entirely new living area. Loft conversions are available in different types including simple Velux loft conversions or larger options such as a dormer loft conversion or hip to gable loft conversion if you want to maximise the space and turn it into a new bedroom, home office space, upstairs living room, or anything else. In the hotter months of the year, however, your loft conversion can quickly become a stuffy, warm, and uncomfortable place to be due to the heat rising upwards throughout the house. Thankfully, there are several ways to keep your loft conversion cool in summer.


Smart Velux windows are a popular choice for adding ventilation to the room, as they open automatically when the temperature in the room is too hot, and close automatically when the temperature drops or it rains, so you don’t have to worry about them. If you have a larger loft conversion, then you have the room to add larger windows, which you can open and close as needed to regulate the temperature inside. 

Ventilation Installation

Good ventilation in your loft conversion is important for keeping fresh air flowing through. There are lots of options to consider for adding ventilation to a loft conversion, whether you have a basic roof light loft conversion or a large L-shaped dormer loft conversion. Along with windows, it’s important to consider adding ventilation as your loft conversion is being carried out. Holes for ventilation can be drilled into the rafters around the windows or skylights, or you can have insulation installed above the rafters to improve the ventilation in the room.  


We are all aware of the importance of good insulation during the winter season to prevent heat loss from the room. But what you may not have realised is that when your loft conversion is well-insulated, this can also help to keep the room cool when the temperature peaks. In the summer, however, good insulation will prevent your loft space from overheating by preventing the build-up of heat, allowing you to keep the room at a stable and comfortable temperature easily. 

Blinds and Other Window Coverings

Made-to-measure blinds for any windows that you have in your loft conversion can be an ideal way to block the sun’s rays and avoid the temperature rising too high in the roof. Lots of homeowners add a large window or windows to their loft conversion to let in the maximum amount of light to the space. But the problem with this is that it also lets a lot of heat in. In addition to blinds, there is also the option to fix shutters over windows to deflect the heat. Shutters are a great option as they will block the majority of the sun to keep the room as cool as possible, while allowing in enough natural light to keep the space illuminated. 

Air Conditioning

While it may not be the cheapest option for keeping your loft conversion cool in the summer, air conditioning can be very effective. If you are concerned about your carbon footprint or simply want to keep your energy bills lower during the summer months, then it might be worth considering solar-powered air conditioning units in your loft conversion. 

A loft conversion can be an ideal way to add an extra room to your home, but since heat rises, it can be uncomfortable and stuffy in the summer.
