Safety Impact Glass
HOOGOVENS™ FOR EXTREMELY HIGH IMPACT EXPLOSION AND PENETRATION RESISTANT SAFETY WINDOWS. 1-5/16″ Thick glass.
A bar was repeatedly dropped on the test glass to the same location on the glass. All tests were completed without penetration. “Bullet-Proof” or Bullet-Resisting Glass is designed to withstand 130 KGM impact from a machine gun bullet, but will fail with this test dart test at 7.8 KG with a height of 4 meters or 31.2 KGM, versus the HOOGOVENS™ impact resistant glass tested to over 600 KGM without penetration.
Thicknesses available in: 1/2″, 7/8″, 1″.
SAFE-SHIELD™ Safety Glass
Combines impact resistance with heat resistance. Available in 1/2″ and 7/8″ thicknesses.

In 1976, at J&L Steel Company (now LTV Steel Company) in Cleveland, Ohio, a test was conducted using our 7/8” SAFE-SHIELD™ and other products. The test consisted of mounting the windows into a box placed below the slag pit trough and molten slag poured on to the glass. Pictured above is our SAFE-SHIELD™ Glass just after a dumping of 2900° F. slag. The red-hot steel slag can still be seen all around the box. Of all the products tested, MacPherson designed composite glasses were the only ones that passed.
SAFE-SHIELD™ has an Infrared Reflective (IRR) coating on the outer face plate. This allows SAFE-SHIELD™ to be used by itself where the depth is limited to a single glazing or as the final barrier to radiant heat.
