In high-risk environments, protecting entry points is critical to maintaining the security of an entire facility. Whether it’s a government building, correctional institution, retail storefront, or financial branch, door systems play a key role in deterring unauthorized access. At Insulgard Security Products, we specialize in providing tested, certified glazing materials that integrate seamlessly into forced entry-resistant doors—helping architects, contractors, and facility owners meet demanding safety and security requirements.
Building an Effective Forced Entry Door System
An effective forced entry door system is engineered to withstand deliberate, sustained attack. Insulgard’s high-performance glazing products are a critical component of doors designed to meet forced entry standards.
Key Characteristics of Forced Entry Doors
- Glazing must be rated to the same forced entry level as the rest of the door assembly. Underrated glazing can compromise an otherwise secure door.
- Frames and hardware must be constructed and tested to withstand prying, blunt force, and sustained impact. Reinforced frames, mortise locks, and continuous hinges are commonly used.
- Anchorage at hinge and latch points is critical. If the frame isn’t properly secured to the structure, the system can fail regardless of component strength.
- Full system testing—not just individual components—is required for certification. Real-world attacks test the integration of glazing, hardware, and framing together.
The Role of Glazing in Overall Door Performance
When attackers target a door, the glazing is often the first point of impact. To prevent a quick breach, glazing must resist forced entry for long enough to trigger a response or alert. That said, security glazing is just one part of a larger system—it must be paired with robust framing, certified hardware, and proper anchoring to be fully effective.
The entire door assembly should be tested as a unit to ensure that all components work together to meet the required threat level.

Insulgard’s FORCEPROTECT product line offers durable glazing materials engineered specifically for use in forced entry door applications. Designed and tested to meet a range of attack resistance levels, these glazing options are trusted in a variety of building types, from storefronts to secure government facilities.
