How To Keep Your Loft Conversion Cool

Loft conversions are a great way to add space and value to your home. They have become more popular in recent years, especially in cities such as London. It is widely known that lofts can get very hot, especially during the summer months. We are going to look at how to keep your loft conversion cool.

Why are lofts so hot?

Loft spaces get particularly hot because of a variety of factors. Firstly, as the sun hits the roof during the day, that heat gets radiated through the roof space. It is essential that you have adequate insulation to minimise the transfer of heat to the rooms in your home. Furthermore, you need to have your loft properly ventilated in order to reduce the hot air accumulating in the space. Measures should be taken to reduce the impact of other heat sources such as direct light through windows.

Insulation & Ventilation

Proper insulation and ventilation is critical to regulate the temperature in your home. Insulation will keep heat in during the winter months and keep heat out during the summer. When you convert your loft, you change the ventilation requirements of the space. Your loft conversion building contractor will ensure that your newly converted space meets regulation requirements. Another effective way to cool your indoor space is by using open windows and doors to create cross-ventilation. This will replace the indoor air with cooler outdoor air. If it’s a particularly hot day, it is best to wait until the evening as the temperature will be cooler.

Windows

In order to minimise the heat gained in your loft conversion, it is important to consider the sunlight gained through the windows. Limiting the amount of direct sunlight to the room will help keep the room cooler during the day. If your loft windows are facing the sun, consider using curtains, blinds or shutters to block out any direct light.

The colour of your roof will affect the temperature of your loft space. Darker colours will absorb more heat whereas lighter colours will reflect heat and light. If you live in the UK, it is important to note that although a lighter roof will help keep your loft conversion cool in the summer, it may not be a suitable option all year around.

How To Keep Your Loft Conversion Cool With Air Conditioning

Sometimes even with the proper measures in place, lofts can remain an uncomfortable temperature. This is particularly true in built-up areas such as cities and especially during the summer months. At this point your best option is to install an air conditioning system. Available in different types, sizes, colours and budgets, they are one of the most effective ways to cool your indoor space. If possible, we would recommend that you install your system during your loft conversion build.

Benefits of Loft Conversion Air Conditioning

Air conditioning systems offer many benefits beyond just temperature control, these include:

  • Improved air quality
  • Humidity control
  • Reduced odours and fumes
  • Improved sleep
  • Reduced allergens (e.g. pollen)
  • Reduced mould growth

Air Conditioning For Loft Conversions With No External Unit

If you live in a restricted property and cannot install a traditional external condenser, there is an alternative solution. Internal water cooled air conditioning requires no planning permission or external unit. They are ideal for properties that cannot install a traditional air conditioning system. The internal condenser is hidden in a concealed space such as a cupboard or under the kitchen sink. This means that you do not need to compromise on the visual aesthetic of your home.
