Madico's 8-mil safety and security window film, when combined with a wet glaze attachment system has passed the following standard for Windstorm Debris, consisting of impact and cyclic wind pressure testing:
Large Missile Category "B" (4.5lbs.) Impact and Cyclic Pressure testing: International Building Code - ASTM E1886 and E 1996, and SSTD 12-99
Summary: Three sliding glass door test specimens were impacted with a 4.5lb. 2"X 4" traveling at 40 fps; specimen "A" was impacted in the center, specimen "B" was impacted within a 6" radius of the upper right corner, and specimen "C" was impacted within a 6" radius of the lower left corner. In each case the glass was broken by the impact from the 2"X 4" projectile, but the film and silicone restraint system kept the opening sealed. After impact, all specimens were subjected to 9,000 cycles of pressure, both positive and negative up to a maximum pressure of +/- 100 psf, which aquates to a wind speed of 198 mph. (ATL Test Report 0219.02-01)
By passing the Large Missile "B" protocol, this system is also accepted in lieu of the Small Missile requirements, 10 - 2 gram steel ball bearings projected at 130 fps.
Wind pressure testing to ASTM Standard E997-01 was conducted on standard residential windows to see if an application of Madico's 8-mil and wet glaze attachment system using Dow 995 structural silicone had improved performance versus a stock annealed window glass.
Summary Three (unbroken) standard residential windows glazed with 6mm annealed glass were subjected to varying loads of wind pressure to determine there failure point. At an average of 80 psf, the glass in each specimen either broke or was ejected from the glazed openong. In turn, three standard residential window were filmed with Madico 8-mil and affixed to the window frame with a structural silicone sealant, Dow Corning 995. When subjected to the same protocol as the unfilmed windows, these window had an average failure at 115 psf which is in excess of 200 mph. meaning when subjected to wind load only, the filmed and wet glazed attached windows withstood 30% more pressure than the unfilmed windows.
