Surface-mounted exterior shutters — exposed or plastered box
Surface-mounted exterior shutters are a practical and premium solution when you want real solar protection, better light control and more comfort without redoing the window opening. They mount on the joinery or wall — often chosen in renovations and modernisations. At Kulttur: aluminium, plastered or exposed, manual or electric, custom colours and sizes.
Surface-mounted exterior shutters mount on the joinery or directly on the wall, outside. Not factory-integrated with the window like some built-in systems, but added later — very useful in renovations and modernisations.
Depending on project: exposed box or plastered version for a more discreet look.
The logical choice when the project is already built and you want efficient exterior shading without redoing the whole window.

We review the plans, discuss technical details (triple glazing, RC2/RC3, acoustics, sealing) and propose the right Internorm window configuration for your home or project.
Benefits go beyond shading — daily comfort, light control, less overheating, extra window protection.
Reduce thermal exchange through the window. When closed, improve the opening's thermal behaviour. Up to 25% better insulation, depending on configuration.
Beyond shading, acoustic comfort. Doesn't replace acoustic glass but reduces perceived noise and blackout, especially in bedrooms or street-facing rooms.
Work as physical and visual barriers. Motorised versions may include anti-lift and auto-stop on obstacle — safer use and deters quick forcing attempts.
Aluminium exterior shutter blocks sun before reaching the glass — major vs interior solutions. Summer: south/west rooms — up to 10°C lower interior temperature vs unshaded.
Design flexibility: exposed box (clear) or plastered (discreet). Box and guide colours match facade and joinery. Fits well with PVC-alu windows.
Installation depends on window, facade and variant. A well-planned detail helps appearance and long-term operation.
Most common in renovations. Mounts directly on the wall — good when you don't want to touch existing joinery.
Used when the system must align precisely with the window and configuration allows. Good for clean projects with tight detail control.
Plan the box space, finish transitions and service access. Not complex but requires planning. Proper pre-installation consulting makes the difference.
Technical details separate standard from premium-feeling systems. Slat material, box stability, guides, motor safety all matter.
Most appreciated in premium: double-wall aluminium slats with PUR foam. Good rigidity, better thermal/acoustic comfort.
Guides and box aren't just housing. Affect operational stability, facade look, long-term behaviour. Weather-resistant, easy to service.
Modern motors may include anti-lift and auto-stop on obstacle. More safety, less forcing risk.
