What are the through vision requirements for security grilles?

Local authorities and retail centre owners usually require commercial shop premises to offer a level of through vision for shop front security grilles. This is to provide an visually attractive, aesthetically-appealing look when locked out of business hours.

This can be achieved through an open-vented or glazed security grille. The HAG range offers designs with up to 80% through vision. Please speak to our estimating team to discuss the options for your requirements.
