Building Envelope Protection = Property & Life Protection:
During a severe weather event, the most critical factor for increasing the chances of a building’s survival is protection of all the openings to the outside. Once the wind enters the structure, the pressure changes lead to disastrous results.
Impact testing simulates windborne debris striking a window during a hurricane. Within the laboratory setting, this is done by firing a 2×4 projectile at predetermined locations on the window and seeing if there is any penetration.
The cycling portion of the testing ensures that a window having withstood impact by the 2×4 can then stand up to the rapid increases and decreases in pressure within the building during a hurricane.
