The following tables illustrate the available levels of security which are available. From burglar proof to bullet proof.
Security level A3 (DIN 52290 T4) 10mm/3/8" UL 972
Security level B1 (DIN 52290 T3) 18mm/3/4" UL 972
Security levels C1 through C5 (DIN 5229 2C) UL 752 1-8
Equivalent to EN 356/UL 975 rated impact resistance. Creating a barrier that deters intrusion and protects your home. Also ideal for extreme weather such as hurricanes and tornados to protect from flying debris. The DIN standards surpass the Dade county Florida large missile test such that the impact of a steel ball has a more concentrated force than a 2 X 4's surface area.
Bullet resistant entrance door level C1 certified to stop 9mm rounds fired 3 times. Frame is manufactured out of Mahogany wood clad with bronze anodized aluminum. Installed with hardened steel bolts around the perimeter of the frame. Multi-point locking mechanism with 3 bolts on the jamb side.
Steel reinforced UPVC frames can hold glazing up to a thickness of 32 mm or 1.22 inch. For glazing thicker than that, a steel reinforced aluminum frame has to be used. Depending on the level of security, the increased weight of the glazing is an important factor in designing opening windows and doors. Each opening mechanism can carry a given load. A tilt / turn or turn only mechanism can carry up to a maximum of 270 pounds. The tilt-slide sliding door up to 330 pounds and the slide only sliding door up to 660 pounds. If the weight is above this limit, the openings have to be reconfigured by using a combination of fixed and opening panels
