Roller Shutters - the all-rounder in sun protection

Roller Shutters are installed as a permanently closed surface in front of the window and therefore offer particularly comprehensive protection.

Your advantages:

  • Comprehensive protection: Roller Shutters almost completely prevent the entry of light and thus protect against overheating in summer.

  • Energy efficiency: insulating in winter, heat protection in summer.

  • Security: make break-in attempts more difficult.

Blinds at a glance: external and internal variants

ROMA Venetian blinds are among the classics in sun protection - both indoors and outdoors. While external Venetian blinds impress above all with their precise light control, high summer heat protection and modern façade design, internal blinds score points with their simple installation, flexible light control and diverse design options.

Their advantages:

  • Modern façade appearance: clear lines, filigree look.

  • Summer heat protection: blocks the sun's rays before they heat up the glazing.

  • Daylight utilization: the view to the outside is maintained despite privacy protection.

External venetian blinds combine elegant design with high functionality and create a pleasant, glare-free indoor climate at any time of day.

Internal Venetian blinds - flexible and versatile

Internal blinds consist of adjustable slats made of aluminum, wood or plastic and are mounted on the room side of the window.

Advantages of internal blinds:

  • Simple installation: no structural work required, ideal for rented apartments.

  • Individual light regulation: slats can be infinitely adjusted.

  • Wide variety of designs: large selection of colors and materials.

  • Cost-effective: inexpensive solution for privacy and glare protection.

When is it worth replacing Roller Shutters with Venetian blinds?

It can make senseto replace Roller Shutters with Venetian blinds if you want more daylight with simultaneous glare protection, if you want to visually enhance the façade or if you value precise light control (e.g. in offices or living rooms with computer screens). These are advantages that External Venetian Blinds fulfill.

Conversely, it is worth switching to Roller Shutters if there are high security requirements, maximum weather protection is required or good darkening is needed, for example in the bedroom.

Which solution is better?

The decision "blinds or Roller Shutters" depends on your priorities: Roller Shutters score points with all-round protection, security and energy efficiency. External blinds offer flexible light control, modern design and a high level of thermal insulation in summer, while internal blinds are particularly impressive due to their simple installation, diverse designs and variable privacy protection, but keep out significantly less heat.

In many projects, a combination also makes sense - for example, External Venetian Blinds on the south side for daylight control and Roller Shutters in bedrooms for almost complete darkening. ROMA offers both systems in premium quality - individually plannable, automated on request and color-coordinated for a harmonious façade appearance.

Frequently asked questions (FAQ) about Roller Shutters and Venetian blinds

What is more effective against heat - Roller Shutters or blinds?

Both systems are very effective as external sun protection. Roller Shutters block heat completely, external blinds reduce the heat input and let in daylight at the same time. Internal blinds, on the other hand, offer variable privacy and glare protection, but can only reduce heat development to a limited extent, as the sun's rays hit the window glass and heat it up.

Can Roller Shutters and Venetian blinds be retrofitted electrically on the outside?

Yes, both Roller Shutters and External Venetian Blinds can be retrofitted with motors. Wireless solar drives are particularly convenient to operate, as they work independently of the power grid and are ideal for retrofitting - without any complex wiring or structural work. Depending on the equipment, both systems can also be integrated into Smart Home solutions and conveniently controlled via app, radio remote control or automatic timer.

Can you darken with blinds in the same way as with Roller Shutters?

No, blinds - whether internal or external - do not allow complete darkening. They are primarily designed to direct light and always allow some daylight through when closed. Roller Shutters, on the other hand, close completely and can stop the light coming in almost completely, which makes them ideal for bedrooms or rooms with a high need for darkening.

Textile Screens can also achieve a strong darkening effect depending on the selected opening factor, making them an interesting alternative to Venetian blinds and Roller Shutters.

Can I replace Roller Shutters with Venetian blinds without changing the façade?

Whether you can replace Roller Shutters with external blinds without making structural changes to the façade depends on the construction method. ROMA specialist partners will check on site whether the existing roller shutter boxes and guide rails can be used.
