Insulgard offers several SAFECHANGE bullet-resistant accessories for use in our counterline systems or your existing workspace, including overhead louvers and speak-thru systems.

Our SAFECHANGE overhead louver systems are designed to extend the height of a counterline system at reduced costs. While the louvers are not bullet-resistant themselves, they can help deter attempts to leap over a bullet-resistant barrier and cause a breach in security. The innovative design allows air to flow through the barrier, whereas a solid barrier may otherwise restrict the effectiveness of a heating and cooling system.

We also offer various SAFECHANGE speak-thru systems designed to match the barrier or window they are installed in. Made of transparent, bullet-resistant acrylic or polycarbonate, our backer plate speak-thru delivers excellent voice communication between the employee and the customer. For added security, choose our round stainless steel speak thru, which features Level 3 bullet resistance and a design that deflects projectiles effectively.

All of Insulgard’s bullet-resistant accessories are delivered and ready to install. For more information read the product data sheets below.
