How Big Is the Hood/Casing, and Can It Be Concealed?

When installing roller or security shutters, one of the most common questions is about the size of the hood (also known as the casing or box) and whether it can be concealed. At HVP Security Shutters, we offer flexible solutions to suit both practical and aesthetic requirements, ensuring your shutters are both secure and visually unobtrusive.

What Is the Hood/Casing?

The hood or casing is the enclosure at the top of the shutter that houses the rolled-up curtain and operating mechanism. It protects the shutter components from the elements and helps maintain a neat appearance.

How Big Is the Hood/Casing?

Size Depends on Shutter Dimensions: The overall size of the hood is determined by the width and height of the shutter, as well as the type of slat used.

Smallest Size: 205mm x 205mm (typically for smaller residential shutters).

Average Size: 350mm x 350mm (for larger commercial or industrial shutters).

For particularly large shutters, the hood may be larger to accommodate the increased curtain roll diameter.

Can the Hood/Casing Be Concealed?

Yes, the hood or casing can be concealed within a soffit, lintel, or recess to achieve a discreet finish. Concealing the casing is a popular choice for architects and property owners who want a seamless look. However, it is essential that the design allows for maintenance access to the shutter mechanism for future servicing or repairs.

Maintenance Access Is Essential

Even when concealed, the hood must remain accessible for routine maintenance and emergency repairs. Our team will advise on the best ways to integrate the casing into your building’s structure without compromising serviceability.
