With the rising temperatures in summer, protection against overheating in living spaces is becoming increasingly important. However, not every property is sufficiently equipped for this. Owners can effectively prevent this with targeted structural and technical measures and thus ensure greater living comfort - without the need for air conditioning.
External sun shading works best
Roller shutters, awnings and blinds on the outside of the windows stop the heat before it can penetrate the building. The investment is particularly worthwhile for large windows facing south or west. Important: Internal privacy protection has a visual effect, but is much weaker thermally.
Insulation and building physics are key
A well-insulated building envelope not only keeps the heat in the house in winter - it also protects against the ingress of hot air in summer. The roof plays a particularly important role: if it is poorly insulated, the house heats up more quickly. Retrofitting insulation can achieve great effects here.
Sustainable cooling through greening and ventilation
Façade or roof greening acts as natural climate protection. At the same time, targeted ventilation - for example at night or in the early hours of the morning - can bring cool air into the house. If you also use fans or heat pumps with a cooling function, you can often do without air conditioning units.
Conclusion
Summer heat insulation is easy to implement with structural measures and not only protects against heat, but also reduces energy costs. A clever combination - with shading, insulation and targeted ventilation - ensures pleasant temperatures even on hot days.
