Defender System Innotech windows and doors provide effective security against casual break-ins*. Our windows and doors are equipped with the Defender System - an integrated set of features that includes multipoint locking hardware, steel reinforcement and welded frame construction. Multipoint Locking HardwareEach window and door sash is surrounded by a band of steel hardware that securely bolts to the frame at multiple points. The number of locking points increases with the size of the window or door. In the tilt position, the Defender Hardware System prevents the sash from being opened completely. This allows you to tilt your windows and doors for ventilation, without concern for forced entry. Steel Reinforcement Each window and door is internally reinforced with structural galvanized steel. The unseen steel not only provides structural strength, but also makes the framing stiffer and resistant to forced entry. Welded Corner ConstructionEach window and door sash is welded together into a one-piece, internally reinforced assembly that cannot be disassembled or broken apart. Security GlassFor additional protection and peace of mind, you can select impact resistant glazing to make the glass as resistant to break-ins as the framing - even in high-risk environments. Add It All UpA common point of entry for intruders is through a window or door that has been kicked in or forced open. The combination of the multipoint locking hardware, steel reinforcement and welded frames and sash corners, make it nearly impossible to quickly kick in the door framing or forcefully open the window to protect you and your home against break-and-enters.
