Hurricane, Tornado and Extreme Weather Protection

Impact-resistant windows consist of laminated glass surrounded by a heavy-duty frame that is securely fastened to the window header and frame. Their construction and anchoring with hardened steel bolts keep hurricane winds and debris from breaching your home’s outer envelope. The idea for shatter-resistant glass windows for homes came from the automotive field, where laminated glass has been in use for years to protect occupants. Laminated glass consisting of two or more sheets of glass with an inner shatter-proof membrane between them. Once the glass receives a significant impact, it may shatter but the inner membrane holds the pieces firmly in its frame so that the barrier is not broken. These windows are designed to handle wind-borne debris hurled at high wind speeds, as well as repeated impact from would-be intruders.

Prevent Damage

Windows offer a significant opportunity for combined wind and water damage in hurricanes, but manufacturers originally came up with impact-resistant windows to save structures from destruction. A broken window provides a point of entry for wind, which enters the house, increases pressure, and seeks another way out.

Hurricane impact resistant products use a thicker sandwich of glass and special film interlayer to make the glass unit stronger. Laminated glass also eliminates 99% of UV rays, reduces noise transmission, provides enhanced security protection for your home, and reduces the air conditioning and heating portion of your energy bill.

According to the code, the windows must meet requirements for large and small missiles. It specifies that for large missiles, the window has been tested with an impact from a six-foot-long 2×4 weighing nine pounds, traveling at 50 feet per second. The test is done in a laboratory setting with the lumber fired from a cannon into the window. The window glazing must remain intact after the impact.

The small missile test exposes the window to a variety of impacts with 30 pieces of roof gravel traveling at approximately 80 feet per second or 50 miles per hour in order to meet the certification requirements. Current tests actually use steel ball bearings for uniformity in test conditions.

Laminated Security Glass Specifications (A 3) for Fauser Windows:

1. All Fauser Windows with laminated security glass (A 3) are marked with one or both of the following descriptions: A 3, DIN 52290

2. The standard laminated security glass is manufactured and tested to the exact specifications of the German National Institute for Glass and the German National Institute for International Norm, form DIN 52290 A.

3. Security glass with an A 3 rating (DIN 52290 A) surpasses the safety of tempered glass. Even after repeated impact by sharp or blunt instruments, the glass is held together by a laminate and can therefore not break into shards and splinters. It is approved by the German Goverment for the use in high rise buildings and all other applications where safety glass is mandated.

4. The stamp on the glazing warrants the above specifications and certifies the performance according to DIN52290 A, DH 4 and is VdS approved.

5. A 3 security windows and doors with an A 3 rating (DIN 52290 A) have to withstand the impact of a 9 pound steel ball, dropped on the glass from a height of 31.2 feet. This test is repeated 7 times and no penetration is allowed.

6. The glazing consist of 10mm laminated glass on the attack side, 10mm Argon filled insulation space and an inner, 4mm and lowE coated glass panel.

7. The multi-point locking mechanism has to have a minimum of 7 Cam Locks per opening. 8. The installation of the units to the above specifications requires the use of (included) ¼“ hardened steel bolts, fastened through the pre-drilled holes in the jambs.
