HS Armor Panels

Strongwell’s HS Armor fiberglass armor panels are designed for ballistics resistance. The panels are manufactured using specially constructed glass reinforcements in a proprietary resin matrix. The panel components are then cured in a controlled cycle.

Products_Ballistic-Panel-TestWhen struck by a bullet or other projectile, HS Armor panels delaminate in a way that absorbs the energy and stops the projectile. Thousands of these panels have been purchased by the military, law enforcement, and numerous private and public sector organizations to provide an extra layer of protection for its people.

HS Armor panels have been independently tested to Underwriter’s Laboratory (UL) 752 and National Institute of Justice (NIJ) Ballistics Specifications. Please refer to the chart elsewhere in this brochure for the classifications of panels meeting UL 752 and NIJ requirements. Regarding fire performance, HS Armor panels are self-extinguishing and meet a UL 94 V-0 flammability rating.

HS Storm Panels

Products_Storm-Panel-TestStrongwell's fiberglass HS Storm Panels are designed for high impact performance. The panels are made with a proprietary resin mix and fiberglass fabric consisting of woven rovings to create panels that absorb large amounts of impact energy. Independent testing at Texas Tech University's Wind Science and Engineering Research Center has verified HS Storm Panels meet the criteria of FEMA 320 and are suitable for above ground shelter sheathing.

To meet FEMA 320 standards, a panel must withstand a 15 lb. 2x4 timber missile propelled at 100 mph. This relates to a missile propelled horizontally by a 250 mph ground speed tornado. Strongwell's 1/4" thick HS Storm Panel meets the FEMA 320 criteria whereas 5 layered sheets of 3/4" thick plywood failed. The videos available in the right sidebar of this page allow you to see the performance of HS Storm Panels in the simulated environments of both a hurricane and tornado.
