Fitting Security Grilles or Shutters
Internally or Externally
On the continent they fit Security Grilles and Shutters externally; this is usually for Shading and Ventilation reasons.
In this country the Police and Insurance companies recommend that grilles are fitted internally. The reasons for this are;
| Fitted Internally | Fitted Externally | |
| Physical Attack | The thief would have to break the glass and then break through the grille, while the alarm is sounding. | The grille can be attacked all day without anyone knowing about it. |
| Fixings | The fixings are concealed within the grille, so it would be very difficult to undo the fixing through broken glass and with a door/window frame in the way. | The fixings are fully exposed, even if security fixings are used the bricks that hold the fixings, can easily be broken. |
| Product Life | As the grille is fitted internally the product is not going to subject to weathering and corrosion. | Even if the grille is Fully Hot Dipped Galvanised and Powder Coated, it is vulnerable to getting chipped and rusting, which reduce the life of the product. |
| Ease of Use | The grilles fitted internally require the minimum amount of maintenance and can be easily operated from inside. | Grilles fitted externally, require regular maintenance and sometimes have to be operated from the outside, which could mean going out in the dark and wet conditions. |
Roller Shutters are usually fitted externally; this is usually because they are used for Vandalism as well as security. To achieve a Maximum Level of Security we would always advise fitting them internally.
