Benefits of VELUX solar shutters and blinds for blackout and thermal protection without heavy electrical works.

Solar solutions recharge via an integrated panel — ideal for lofts where running cables is complex.

An external roller shutter blocks heat and boosts insulation. An interior blind manages light. An external awning limits summer overheating.

Most VELUX accessories fit existing windows, even older ones. An assessment confirms compatibility.

Do solar shutters work in cloudy weather?: Yes — batteries store energy and cover less sunny periods.
Must the window be replaced to fit a shutter?: Not necessarily. Many shutters fit existing frames.
