What Is the Ideal Home Temperature and How Can You Achieve It?
Finding the ideal temperature at home is not always easy. Some people feel comfortable in a warmer room, while others prefer a cooler environment. In many homes, one room may feel warm and comfortable, while another feels cold, damp or difficult to heat.
The ideal home temperature is not only about comfort. It also affects energy use, heating costs, condensation risk and the overall performance of the building.
What is the ideal temperature for a home?
As a general guide, many energy efficiency recommendations suggest keeping living areas at around 20 to 21°C during the day and bedrooms slightly cooler at night, often around 15 to 17°C.
These temperatures are only a guide. The right temperature can depend on the age of the building, insulation, ventilation, heating system, humidity levels and personal comfort.
For most homes, the goal is simple: keep the property comfortable without wasting energy.
Why stable temperature matters
Large temperature changes can make a home feel uncomfortable and can also increase energy use. If a room becomes very cold and then needs to be heated quickly, the heating system has to work harder.
A more stable indoor temperature can help:
- improve comfort,
- reduce unnecessary energy use,
- lower the risk of condensation,
- make rooms easier to heat,
- create a healthier indoor environment.
Instead of constantly overheating the house and then letting it cool down too much, it is usually better to maintain a steady and comfortable temperature.
Adjusting temperature when the home is empty
When nobody is at home, it may be sensible to reduce the heating temperature instead of heating the property as if it were occupied.
However, the home should not be allowed to become too cold, especially in damp climates. Very cold internal surfaces can increase the risk of condensation when the heating is turned back on.
The right setting depends on the property. A well-insulated home can usually maintain temperature more effectively, while poorly insulated homes lose heat quickly.
Why heat escapes from your home
If your home is difficult to keep warm, the problem may not be the heating system itself. Heat can escape through weak points in the building envelope.
Common causes include:
- poor wall insulation,
- cold external walls,
- gaps around windows and doors,
- poor attic or roof insulation,
- thermal bridges,
- cracks or damaged external surfaces,
- poorly sealed extensions or older construction details.
When heat escapes too quickly, the heating system has to work harder, and the home may still feel cold.
Improve insulation and surface performance
One of the most effective ways to maintain a comfortable home temperature is to improve insulation and reduce heat loss.
This can include attic insulation, better windows and doors, wall insulation, sealing gaps and improving the performance of external surfaces.
A properly protected external wall can help reduce the cold surface effect, improve comfort and protect the building from weather exposure.
Can spray cork help improve thermal comfort?
Spray cork is a modern protective coating made with natural cork and water-based resins. Because cork has a natural air-filled cellular structure, it can help improve thermal comfort on treated surfaces.
When applied to external walls, façades, roofs or metal cladding, spray cork may help reduce the cold surface effect and support better temperature balance inside the building.
It is important to be realistic. Spray cork should not be presented as a complete replacement for traditional insulation systems. However, as part of a suitable renovation or protection system, it can contribute to improved comfort, reduced thermal bridging and better protection of external surfaces.
Breathability is also important
A building needs protection from rain and weather, but it also needs to breathe. Some coatings can trap moisture inside the wall, which may lead to damp or condensation problems over time.
Spray cork helps create a protective external layer while still allowing water vapour to escape. This balance between protection and breathability is especially useful in climates where buildings are exposed to regular rain, wind and changing temperatures.
Simple steps to achieve a better indoor temperature
To make your home more comfortable and energy efficient, start with the basics:
- keep a stable indoor temperature,
- avoid overheating rooms unnecessarily,
- reduce the temperature when the home is empty,
- check windows and doors for draughts,
- improve attic and wall insulation where possible,
- make sure ventilation is working correctly,
- protect external walls from weather and moisture.
The best results usually come from combining several improvements rather than relying on one single solution.
