With over 25 years of experience in manufacturing and installing window security grilles, these are only some of the work we have completed on a wide range of home and office windows, for a wide range of customers. Window security grilles represent a physical barrier as well as act as a visual deterrent, whilst they have a slim and tidy look that takes up a minimal space when they are retracted. They also look very aesthetic from the outside as well as from inside, and also very smooth to operate. They slide easily with only using one finger. Our sliding window security grilles come in the widest sizes and ranges, in fact they are all made bespoke for each window.
