Insulation, security, comfort: the roller shutter has become the standard fitting on French windows. Here is the essential knowledge to choose well.

The installation types

Traditional (built-in): box hidden in the masonry, ideal for new builds
Renovation: visible box fixed to the existing window, without major work
Window-block: window and shutter delivered as one unit, common in full replacements

PVC or aluminium?

PVC is economical and insulates well, but is limited to modest widths. Aluminium, barely more expensive, lasts better, allows large sizes and offers foam-filled slats: it is our recommendation for most uses, and essential where security matters.

Manual or motorised?

Strap and crank remain reliable and cheap. Motorisation (wired or radio) brings comfort, time programming and presence simulation; it is strongly advised for large openings with heavy curtains.

Fitted price ranges

Manual PVC shutter in renovation: roughly €200 to €400 per window
Motorised aluminium shutter: roughly €400 to €800 depending on size
Motorising an existing manual shutter: roughly €250 to €450

Our advice before buying

Demand a detailed quote (motor brand, warranty, slats), choose anti-lift locks at ground level and think about maintenance: a cleaned, adjusted shutter lasts fifteen years and more. Our teams install and repair all roller shutter types in Île-de-France, with a free quote.
