Acheiving Your Ideal Security Grilles Design

Whether you want a secure front door grille design as a feature for your house or attractive security grilles for windows indoors which appears almost invisible there are a number of considerations to keep in mind.

5 Important Choices for Attractive Security Grilles Installation

There are a number of decisions to make when choosing security grille designs for windows and doors. An experienced security grilles specialist will advise you on making sound choices when designing your bespoke security grilles.

1) Internal or External Security Grilles?

There are various factors that may dictate whether you have the option to have window security grilles indoors or outdoors. The decision can come down to preference and practicality but what is feasible can often be dictated by the layout and configuration of a property.

External Grilles Installation

We get lots of requests for external security grilles installation. This can work well but is not always the most suitable option and it is not always possible. For example,

  • If your windows open outwards external grilles can prevent windows from opening
  • If your property is in a conservation area external grilles may not be allowed

They work well when there are no restrictions and windows open inwards or with sash windows. When grilles are installed on the outside of a property they can be locked from the outside and the inside.

Internal Grilles Installation

Internal security grilles can be designed to look practically invisible or they can be made to be an attractive feature. Grilles inside a property allow the user to lock up without going outside. Internal window grilles work well but it is often better to have a door gate installed on the outside.

Sometimes a combination of internal and external security grilles works well.

3) What is the Best Layout and Configuration?

When it comes to designing security grilles it is important to have a thorough understanding of the installation process, what will work in the property and what will be most convenient for the homeowner. For example;

  • If a patio has a standard door which opens on the left it may be advisable to stack the security grilles to the right when open to avoid the doorway being obstructed
  • If a window design in symetrical stacking the security grilles 50/50 to each side makes sense

It is all in the detail. Foresight, experience and knowledge is important when planning the finer details of made to measure grilles design. In some security grilles companies quotes and measure ups are done by sales people with no grilles installation experience. Always check that your choosen security grilles designer has expertise in the installation and completion of projects in addition to experience in precise measuring, planning and design.

  • Letter box
  • Cat flap
  • Windows opening
fixed window bars

Or more decorative features such as adaptions to;

  • Accomodate window boxes
  • Add a bespoke decorative design within the metal
