The thickness of the aluminium and the shape and size of the profile along with the strength and flexibility aluminium has to offer it is designed to make attack difficult and the all-important overall security performance strong. When the Aluminium is installed the glazing bead is the strip of aluminium that clips into the frame to hold the glass in place. The window is then designed so that the glazing bead is on the inside, meaning there is no way that any potential intruders can remove the bead and glass from the outside to gain access. As an additional extra, we also offer electric roller shutters which we can fit once the shop-front is in place. Most customers having a shop-front fit often go for the option of a roller shutter due to the amount of extra security it will offer.
