Forced Entry Ratings
Forced entry is a persistent threat to retail stores, financial institutions, schools and other buildings where items of value are kept. Insulgard’s FORCEPROTECT security products are designed to protect against a wide range of forced entry threats—from blunt instruments to cutting tools and thermal stress—and meet the strict standards of the most respected forced entry testing agencies in the industry.
When architects, glazing contractors, and other construction professionals need to build secure environments, they turn to Insulgard security products for trusted and tested solutions
AMERICAN SOCIETY FOR TESTING MATERIALS (ASTM F1233-08) TESTING SEQUENCE
The American Society for Testing and Materials (ASTM) is a globally respected standards organization that conducts rigorous field tests on the durability of forced entry-resistant materials.
The F1233-08 testing sequence defines three factors that contribute to the success or failure of a forced entry breaking through a glazing material:
- The type of tool used
- The techniques with which the tool is employed
- How long the attack lasts
See the table below for specific information on the levels of threat protection as defined by this testing sequence:

AMERICAN SOCIETY FOR TESTING MATERIALS (ASTM F1915-05)
The ASTM F1915-05 testing sequence measures the forced entry resistance of glazing materials in detention facilities, also taking into account the type of tool used, the techniques employed and the duration of the assault.
| Security Grade | Time Rating | Sequence 1 Blunt Impactor | Sequence 2 Sharp Impactor | Sequence 3 Blunt Impactor | Total Impacts |
|---|---|---|---|---|---|
| 1 | 60 minutes | 150 | 300 | 150 | 600 |

HP WHITE-TP-0500.03 (FORCED ENTRY TEST PROCEDURE) TESTING SEQUENCE
Although HP White ceased operations in March 2023, it is still a standard seen in the industry. This forced entry testing conducted by HP White Laboratories measures a glazing material’s resistance to a wide range of threats, from sustained impacts from a sledgehammer to stress induced by torches and chemical agents.
| LEVEL I | LEVEL II | LEVEL III | LEVEL IV | LEVEL V | |
|---|---|---|---|---|---|
| TOTAL FORCED ENTRY SEQUENCES | 5 | 15 | 26 | 39 | 54 |
| (a) Pinch or ripping may be substituted for any portion of Blunt Impacting Sequence at rate of 1 minute for each 5 impacts (Test Director Option) (b) Additional sequences of one minute intervals in conjunction with all Sharp Tool Sequences except sequences 5 and 15 (re: Test Protocol HPW-TP-0500.03 paragraphs 3.5.7 and 3.5.8) |

What Level of Protection Do You Need?
Insulgard’s FORCEPROTECT glazing material products are designed to protect against varying levels of threats. The level of protection you need will depend upon factors such as:
- The presence of crime: The presence of burglary, vandalism, assaults, and other crimes in the neighborhood in which you are building, and the value of the assets you are protecting, will help determine the level of forced entry protection you need.
- Threat assessment: What kind of threats is your building likely to face? A small retail store may face quick “smash and grab” attempts that require a smaller level of protection, while a bank or government building may need to defend against stronger and more coordinated attacks.
- Regulations: Depending upon the jurisdiction in which you are building, you may be required to build with forced entry-resistant glass and other architectural security products.
Our security experts will work with you to help you select the products that are right for your building project, so you can establish the strongest forced entry resistance where you need it the most.
