Built-on roller-shutters: closed really means closed

<< overview shutters
Built-on roller-shutters are placed on top of the window frame. With the practical built-on system, Harol guarantees problem-free installation both during renovations and in new constructions. The newcomers, OB440 and OB450, are an ideal combination of safety and design.
  • Sophisticated design: with its rounded revision board, the OB440 looks modern. Easy to open, standard heat-insulated and available with finishing profiles and sound insulation. Due to its rounded revision lid, the OB450 has a contemporary design. Thanks to the accompanying corner profile with adhesive strips, the compartment can easily be installed on top of the window. The compartment can even be plastered over. And as if that weren’t enough, you can place an insect screen or sliding door in both models.

  • Windproof comfort: your home is insulated a good deal better with built-on roller-shutters: a saving of up to hundreds of euros per year.

  • Silent: with the specially designed narrowing chutes, your roller-shutter will open and close remarkably quietly.

  • All your favourite colours: built-on roller-shutters are available in any RAL colour, so they will match your outside window and door frames.

As far as the roller-shutter slats are concerned, you can choose from a range of aluminium and PVC slats. Both types of built-on roller-shutters are characterised by their modern design and their sturdy construction. Both types of roller-shutters are suitable for new constructions and renovations and go perfectly with wooden, PVC and aluminium windows. Another aspect that cannot be ignored is the additional protection that an built-on roller-shutter gives your home.

Tip: thanks to the revision board of the roller-shutter compartment the mechanism is always easy to reach for maintenance.
