To prevent heat build-up and prevent the interior from heating up uncomfortably, it is important not to close Roller Shutters completely when it is hot. Especially with large glass surfaces and windows facing south or west, a room can quickly heat up to over 30°C without sun protection.
A closed Roller Shutters acts like a protective shield against direct sunlight and significantly reduces the heat input. However, it is important that the Roller Shutters are not fully lowered so that warm air can escape through the ventilation slits.
Optimize the thermal insulation in your home with ROMA Roller Shutters:
Roller Shutters should not be closed completely when it is hot, otherwise heat can build up between the Roller Shutters and the window.
Roller Shutters with ventilation slits allow air to circulate comfortably even when the sun protection is lowered and reduce heat build-up.
Aluminum Roller Shutters prevent heat build-up, effectively reflect solar energy and support thermal insulation in summer.
Ideal position: Leave Roller Shutters slightly open to block the sun's rays and allow warm air to escape.
Roller Shutters are one of the most effective measures for summer heat protection on windows. They are fitted on the outside in front of the glass and stop most of the sun's rays before they reach the window. As a result, significantly less heat enters the interior, because the earlier the solar energy is intercepted, the less the interior of a building heats up.
In particular, high-quality aluminum Roller Shutters with ventilation slits effectively reflect the sun's rays and ensure a pleasant indoor climate, as the air can continue to circulate when they are slightly open.
In addition to optimum thermal insulation in summer, Roller Shutters offer other practical advantages:
Darkening and glare protection for living rooms and bedrooms
Privacy protection at the window from prying eyes
Soundproofing for peace and quiet at night and concentrated work
Improved energy efficiency of the building
Many people make a classic mistake in summer when they want to protect themselves from unpleasant heat: They leave Roller Shutters all the way down in summer to keep out as much sun as possible. However, this can be problematic and increase the heat build-up inside.
When the sun protection is completely closed, a closed air space is created between the window and the roller shutter curtain. The sun's rays heat this gap without the warm air being able to escape. Heat build-up occurs here, which releases heat inwards, heats up the living area and worsens the indoor climate.
A small opening in the sun shading is enough to counteract this. Ventilation slits in the Roller Shutter Profiles allow fresh air in over the entire surface of the blind and prevent heat build-up. Roller Shutters should therefore not be closed completely when it is very hot and should not be completely darkened.
Tip: If your Roller Shutters do not have ventilation slits, you can simply leave a small opening when closing them.
Electric Roller Shutters can not only be operated at the touch of a button, but also integrated into a Smart Home system. This not only increases energy efficiency, but also optimizes living comfort - the Roller Shutters close automatically when it makes energy sense and contributes to maintaining a pleasant living climate.
Intelligent operation of the sun shading system offers:
Convenient operation on the move via app
Control via a timer
Combination with sun sensors for optimum heat protection
Correct operation of the sun shading system is the first step towards optimum heat protection on hot summer days. In combination with well thought-out ventilation, the room climate can be optimally regulated.
We recommend the following for the summer
Keep windows closed during the day
Open sun protection and windows in the evening
Use the cool night air
Cross-ventilate rooms for maximum air circulation
Automated Roller Shutters can intelligently support this process: Sensors react to the position of the sun and temperature and automatically adjust the position of the Roller Shutters - for a pleasant room temperature and maximum living comfort on hot days.
Modern ROMA Roller Shutters are specially developed to optimally regulate heat, light and privacy. Whether Front-Mounted Roller Shutters or Top-Mounted Roller Shutters - the highly functional systems from ROMA are available with high-quality aluminum Roller Shutter Profiles with ventilation slits. This allows Roller Shutters to be adjusted so that they effectively block the sun's rays while still allowing air to circulate.
If you would like to know which solution is best suited to your building, we recommend a personal consultation. Use the ROMA specialist dealer search to find qualified partners in your area who can help you with planning and implementation.
No, Roller Shutters should remain slightly open when it is very hot. This prevents heat build-up in front of the window and the interior does not heat up uncomfortably.
Correct ventilation helps to reduce the heat load in the building. Windows should remain closed during the day, while intensive cross-ventilation is recommended in the evening and at night. In combination with slightly open Roller Shutters, this creates a pleasant indoor climate.
Ventilation slits in the Roller Shutter Profiles ensure that air can circulate between the window and the roller shutter curtain. As a result, warm air does not collect in front of the window and heat build-up is prevented.
With a ROMA Smart Home system, you can control your Roller Shutters automatically depending on the position of the sun, temperature or time of day. As a result, the Roller Shutters close in good time when the sun is strong and open again when it makes sense to ventilate.
